The computer requirements depend on your media type. For example, playing multiple HD videos requires a good computer. A rule of thumb is you can play one full HD video @ 30fps for each 2 GHz CPU core. So if you have an Intel i7 4 GHz (4 cores), you should be able to play 8 full HD videos. Increasing the playback speed to 2x means the fps also increases two times and the number of videos you can play simultaneously is roughly divided by two.

The next table shows the approximate number of videos you can play simultaneously at 30 fps depending on your CPU.

For live video performances, when you want to change the playback speed and go up to 10x, the recommended video resolution is 640x360.

To use the built-in effects, particularly the eye candy effects, the video card will be doing the hard work. If you’re using a laptop, make sure it can sustain a continuous use of the effects without overheating. Usually, an integrated video card can render two eye candy effects. For more effects, you need to have a discrete video card.

About the DMX output, a 1 Gigabit network should be able to handle 2048 universes @ 44fps. For more universes, a supplementary network card and a second Ethernet network are recommended.

Licenses

The ELM’s licensing system has been built with reliability and simplicity in mind. Basically, once a

computer has been activated, it will be able to run ELM until it dies. No internet connection required, so you can be completely off the grid without worrying about the license.

Each license is registered to one individual or company and covers the activation of the software on a certain number of computers, so long as ELM is running on one computer at a time. For example, you can activate a show and a backup computers but only one computer can run ELM at a time.

The license is a simple file that you import once. No hardware dongles are needed, eliminating a whole range of tricky problems: broken dongle, lost dongle, dongle suddenly not detected in the middle of the show, etc.

The license is linked to your computer’s CPU and motherboard. You can upgrade any other components and reinstall the OS without invalidating your license.

A license isn’t transferrable, meaning once your computer stops working, you can only activate

ELM on another computer if you still have activations left. Use this online form to activate a computer: https://www.enttec.com/my-account/license-registration/.

To get more DMX universes, you can activate multiple licenses on the same computer. The DMX universes of all licenses will be added.

Software Updates

You always have access to the latest and greatest version, free of charge.

To get the updates, go in the Settings/About menu and press the check for updates button. Alternatively, you can go on the Enttec’s website and download the latest version.

Definitions

Art-Net: Protocol to transmit DMX over a standard Ethernet network. Designed by and

CITP/MSEX: Controller Interface Transport Protocol/Media Server Extension.

DMX: The most common protocol to control lighting fixtures. The full name is DMX512, which

stands for Digital Multiplex.

DMX universe: Represents 512 DMX channels. Enough for 170 RGB LEDs (1 LED takes 3 channels, one for red, one for green and one for blue).

FPS: Frames per second. It refers to an output rate for video or DMX.

KiNet: Protocol to transmit DMX over a standard Ethernet network. Designed by Color Kinetics.

LED strip/string: Lighting fixture that may contain many LED elements and have a certain

physical length. Some LED strips are flexible and can be bent to create curves and all kind of shapes. ELM handles all lighting fixtures as if they were strips, giving you a lot of positioning flexibility.

Mapping: Mechanism used to associate a pixel from a media source to a specific lighting fixture element.

Media: Any type of visual content, including videos and pictures.

Network Device Interface (NDI): Protocol to stream live videos over the network. Developed

by NewTek - http://NDI.NewTek.com.

Open Sound Control (OSC): Network protocol allowing multimedia apps to communicate. ELM can be remotely controlled via OSC.

RGB, RGBW, RGBA, RGBWA: Various color components: red, green, blue, white and amber.

sACN: Protocol to transmit DMX over a standard Ethernet network - like Art-Net. More

specifically, the E1.31 subset is used for DMX control. Developed by ESTA.

Spout: Real-time video sharing framework for Windows. Similar to Syphon on Mac. http://spout.zeal.co/

Stage: A mapping surface defining the position of the media placeholder and the position of lighting fixtures.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Getting Started With LED Strips

ELM can control any DMX-enabled lighting fixtures – not only LED strips. This is made possible because ELM outputs industry standard protocols like Art-Net, sACN and KiNet. This means that ELM can control traditional DMX dimmers and any RGB, RGBW, RGBA and RGBAW lighting fixtures. It’s also possible to control complex fixtures like moving heads.

Controlling LED strips is a little bit different than traditional DMX fixtures. The main difference is that you need to use LED controllers to drive your strips. They replace the Art-Net nodes you use for traditional DMX fixtures. The LED controller receives DMX via Art-Net/sACN and converts to the special protocol the LEDs understand. Enttec offers the Pixelator which takes 48 DMX universes and controls up to 8160 RGB LEDs.

The next step is to get LED strips and DMX fixtures. Since there are many LED protocols out there, you need to make sure your LED controller fits with your LEDs. Common protocols for RGB LEDs are WS2811 and WS2812/B. For more information about getting compatible LEDs, contact your Enttec representative. Here’s the Enttec Pixelator that can be used to control the Phero and Enttec LED tapes:

Quick Overview

ELM allows dividing your installation into multiple zones and layers called stages. You control the media content independently for each stage. Stages can overlap and they are merged (blended) to generate the final result. A common scenario is to create a stage spanning the whole installation to map media across the board. To enable precise control over specific zones, you create smaller stages inside the big stage. Then you activate these zones whenever you want. For example, in the installation below, we can play a video on the overall stage - which acts as the background layer - and when there’s a special event, we activate the logo zone and make it flash.

To represent your LED strips and DMX fixtures inside a stage, ELM has a powerful vector-based editor. This way, you can easily draw many types of shapes, including matrices, loops and curves. ELM computes the position of each LED based on your drawing.

Home Screen

Welcome! Start a new project or load an existing one. To see the keyboard shortcut keys, press the alt key.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Name

The name of your new stage. Usually refers to its physical location.

Width, Height

The desired size in pixels for the mapping surface used to display media. This can be changed later without affecting the mapping.

Full HD, HD buttons

Presets for common media sizes. Full HD is 1920x1080 and HD is 1280x720.

New Stage Dialog

A rule of thumb is to create a stage with dimensions respecting the aspect ratio of your media. Then you’ll position your LED strips on it to create the mapping. For example, you can create a full HD stage - which has a rectangular aspect ratio - to fit your media sources, and then map a 20x20 square LED array on it.

You can easily change the dimensions later, so don’t worry. The minimum recommended size is 320x180. Smaller than this size, you’ll need to constantly work at a very high zoom level, which isn’t very convenient. So it’s better to use a higher size and let ELM scale your media.

To help you position the strips like they are in the real world, use a picture of your installation as the stage’s background (see Stage Tab). No pictures handy? Use your phone’s camera to get one!

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Stages

Shortcut key: alt-S

You can create as many stages as you want. Generally, you’ll want an overall stage

corresponding to the whole installation and multiple individual stages to target specific zones. The overall stage allows you to map content across the board. Then the other stages allow you to override specific parts of your installation whenever you want. You can select the current stage by clicking its name at the top.

Different effects may demand different mapping layouts. One goal of

the mapping is to ease the content creation. So don’t hesitate creating

multiple stages with the same LED strips but positioned in different ways.

Status Indicator

At the left of the stage’s name, a small indicator tells you the current control mode and its status. The activated status means a media is selected and the stage’s intensity (see Live Mode) is greater than 0%.

Stage Syncing

All stages using the same media slot are considered to be synced. You can still change the individual stage output parameters like the intensity and the color filter, but the media content is the same on all synced stages. When applicable to the media type, the media playback speed is determined by the maximum speed of all stages using this media.

To play the same video file on multiple stages but at different speeds, load the video file in multiple media slots. Then use a different media slot for each stage.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Overwrite

Completely replaces the left stages. The right stage is fully opaque.

Multiply

Multiplies each pixel of the right stage with the corresponding pixel for the left stage. The right stage becomes a video mask.

Screen

The values of the pixels in the two stages are inverted, multiplied, and then inverted again. This yields the opposite effect to Multiply. The result is a brighter picture.

Overlay

Combines Multiply and Screen modes. The parts of the right stage where left stage is light become lighter, the parts where the left stage is dark become darker.

Darken

Takes the smallest color component for each pixel.

Lighten

Takes the largest color component for each pixel.

Difference

Subtracts the left stage from the right stage or the other way round, to always get a positive value.

Add

Adds pixel values of one stage with the other.

Subtract

Subtracts pixel values of the right stage to the left stage.

Black key

Shows the pixels of the left stage only where the pixels of the right stage are black. In other words, black pixels are transparent.

IntensityCrossFade

The stage’s intensity determines its opacity level.

IntensityWhiteFade

The stage’s intensity determines its opacity level in a white fade fashion, meaning that when the intensity is at 50%, both the current stage and the ones under are merged at full opacity.

Stage Merging and Layering

When multiple stages contain the same LED strips, a merge occurs following the order as shown in the Stages Manager. This allows creating complex visuals by layering multiple stages on top of each other. You can target specific zones by creating stages with only a subset of all strips or with parts of the strips outside the stage. A stage must be activated (a media is selected and the stage’s intensity is greater than 0) otherwise it is considered to be transparent and will not be part of the merge.

The merge modes are:

To easily target specific zones of an installation, first create the overall mapping then select the strips corresponding to the individual zones and right-click in the strip list to access the “new stages from strips” menu.

Add a control point

Right-click on the stage (only one strip needs to be selected) or on a control point to use the context menu.

Edit Zone

You can position your strips as they are in the real world or based on the effect you want to create with your media.

A strip has start (green) and end (red) control points indicating the direction of the patch. Multiple intermediate control points can be used to create various shapes. You can bundle multiple strips together to simplify the handling of complex shapes.

You can position parts of your strips outside the stage. In this case, the LEDs outside the stage will not be mapped. This is a common scenario when using the same strips in multiple stages and you want to target specific parts in each stage.

Use the group and sub-group fields wisely in order to use the filter box and quickly select the strips you want.

Add Strips Dialog (Patching)

Shortcut key: alt-A

Quickly patch your strips and lighting fixtures to create arrays and any shapes you can imagine. Multiple LED types (or color types) are supported, including RGB, RGBW, RGBA, RGBAW/RGBWA and white (dimmers) in multiple configurable color temperatures like WWA. Most color component orders (GRB, BGR, etc.) are supported. For lighting fixtures supporting high precision colors, 16 bit color depth can be used via the RGB16, GRB16, RGBA16, RGBW16 and White16 types. RGBWmax activates all channels (RGB+white) when white is needed for maximum brightness.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Number of strips

The number of LED strips/fixtures you want to patch.

LEDs per strip

The number of LEDs per strip. Enter 1 to create a unique fixture.

Type

Also named pixel type. Corresponds to the color component order (RGB, BGR, GRB, etc.) and the capability (white only, RGBW, etc.). Many LED strips have the color components in a different order than red, green and blue. Usually, LED controllers have the option to reorder the color components but ELM can handle this for you.

Shapes

Select a predefined shape (lines, arches, circles, triangles, hexagons, etc.) to position your strips on the stage. For arrays, use lines. Remember that you can create any kind of shapes by adding control points later.

Patching direction

For LED arrays, specify the way your strips are wired to let ELM automatically assigns the proper DMX addresses.

Group and sub-group

Use these two groups to tag your strips and quickly find them later. You can search for these keywords in the strip list’s filter box.

DMX protocol

Select the output method for DMX: Art-Net, sACN or KiNet. Select none to leave the strips un-patched at the moment and not output any DMX.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Start universe

The universe of the first strip to be patched.

Start address

The DMX address of the first strip to be patched.

LED address offset

ADVANCED The number of DMX channels between the start of two consecutive LEDs. Increase it to leave holes

between your LEDs/fixtures, allowing merging ELM’s

output with another console. For example, you can control moving heads by letting ELM handles the colors and a console handles the movement.

Break universe after

ADVANCED Automatically start patching in the next universe when reaching this limit (number of strips of LEDs). Set to 0 to break only when the universe is full.

You’ve got the patching direction wrong? No problem. You can easily

flip your strips horizontally and vertically later. For snake mode, rightclick in the strip list and use the select odd/even option.

Want to control more complex DMX fixtures like moving heads? Let say your moving head has 20 channels and the RGB channels start at 3. In ELM, patch it with a start address of 3 and a LED address offset of 20. ELM will send 0 for the unused channels, which allows merging the DMX data from ELM with the DMX data from a console. The console should provide the values for the pan and tilt and the all other channels except the RGB.

Whites! You can get a more accurate preview by using the right type of white LED type. Use the WhiteCool, WhiteNeutral, WhiteWarm and WWA (cool, neutral and warm whites) LED types. Unlike the White LED type which takes the perceived brightness of the media as its value, you get finer control with the other whites.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

LED Type

Detail

Remark

RGB, RBG, BGR, BRG, GBR, GRB

Red, green and blue.

RGBW, GRBW

Red, green, blue and white.

The white is automatically activated based on the saturation of the media color. The less saturated the color is, the more the white LED is activated. As the white is activated, the RGB LED levels are reduced proportionally until only the white LED is active for a pure white color.

RGBWmax

Red, green, blue and white.

The white activation is calculated like for RGBW but the RGB LEDs aren’t reduced proportionally. The result is that when a pure white color is needed, all RGBW LEDs are activated. While it gives a maximum brightness, it also takes more power.

RGBA

Red, green, blue and amber.

The amber LED is automatically activated the closer the media color is to amber. As the amber is activated, the RGB LED levels are reduced proportionally until only the amber LED is active for a pure amber color.

RGBAW, RGBWA

Red, green, blue, amber and white.

The white and amber LEDs are activated following the same recipe as for RGBW and RGBA.

White

White or one color component only.

The activation level is based on the perceived brightness of the media color (using the luma calculation).

WhiteCool

White cool.

Special type of cool white LED that you can use to get a more accurate preview in the stage monitor. The activation is based on the blue level of the media color.

WhiteNeutral

White neutral.

Special type of neutral white LED that you can use to get a more accurate preview in the stage

monitor. The activation is based on the green level of the media color.

WhiteWarm

White warm or amber.

Special type of warm white LED that you can use to get a more accurate preview in the stage monitor. The activation is based on the red level of the media color.

WWA

White cool, white neutral and white warm/amber.

There are 3 types of whites and you’ll

get an accurate preview in the stage monitor. The white cool activation is based on the blue level of the media color, the neutral on the green and the warm on the red.

WAW

White cool, white warm/amber and neutral white.

See WWA.

AWW

White warm/amber, neutral white and white cool.

See WWA.

…16

High resolution 16-bit per color component.

All types ending with 16 are the 16bit version of the LED type. For example, RGB16 takes 6 DMX channels, 2 for red, 2 for green and 2 for blue. While it takes more channels, it gives smoother color transitions and more headroom for color corrections.

For the color temperature settings to get a more accurate stage monitor preview, see Colors.

Rotate center, offset X, offset Y

The position where the rotation will occur and how to offset the rotation center (for example, to leave a hole in the middle of the rotated strips).

When you’re in the design phase of the lighting installation, keep in mind the duplicate options. They allow creating complex shapes by copying simple elements. This is a real time saver.

To make sure certain strips always stay together, use the bundle feature. You can create complex shapes by combining multiple simple elements. See the bundle/unbundle options in the Edit Zone.

To copy strips to another stage, select your strips and use the copy (ctrlc) and paste (ctrl-v) keyboard shortcuts. You can also right-click in the Strip List to see all options.

When you are editing and zoomed in very closely, if a media is playing in the preview, your computer may have a hard time. To help it, disable the preview by setting the preview opacity to 0%.

Here’s the monitor window. You can see the result of the stage only or after all stages have been merged. When you don’t have access to the real fixtures, this is an indispensable tool while creating effects. Alternatively, you can use any 3rd party visualizer able to receive the LED rendering via NDI (see NDI output in the Stages Manager) or supporting Art-Net or sACN.

Try reducing the stage’s size and see if the output is still good. Also

reduce your videos and other media size accordingly to potentially save a lot of CPU. High resolution media is not always a good thing!

Test patterns On/Off switch

Activates the generation of test patterns.

Color

Changes the color of the testing rectangle. It is handy to test the color component order of your strips.

Width, Height

Changes the size of the testing rectangle.

Test selected strips only

If checked, only the selected strips in the Strips Tab will be under test. The other strips will all be off.

Test 1st LEDs only

Only test the 1st LEDs of each strip to better see where each strip starts.

Locate LEDs

Locates each LED in the real world by going through a list. Alternatively, you can put the mouse over a LED in the editor. The LED number and its DMX address are displayed which is handy to count the LEDs and troubleshoot addresses.

Conflicts

Analyzes all patched LEDs of the current stage and looks for overlapping DMX addresses. In some situations you may want to have duplicated LEDs on the stage but if this isn’t the case, you should adjust the DMX addresses.

Testing Tab

Shortcut key: alt-T

Quickly test the mapping by generating a rectangle that you can move over the strips.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Reduce the width and height of the testing rectangle and drag the rectangle around the stage. This way, you can see if the patch order is right. For example, if dragging the rectangle from left to right makes the LEDs go on from right to left, then you know you need to flip them horizontally. To do so, go in the Strips Tab and click the Flip X button.

Quickly test the red, green and blue component order of your LEDs by generating a pure red, pure green and pure blue test. For each test, note

the color of your LEDs. If you’re not getting a RGB order, edit your LED strips and select the LED type corresponding to the order you’ve observed (BGR, GRB, GBR…).

While the testing mode is active, the DMX is constantly being outputted

at the full output rate, even when there’s no change. This is handy while you’re configuring your LED controllers and want to see if it’s working.

This is also a good way to test whether your network supports the load.

Use the “test selected strips only” option, go in the Strips Tab and

change the selection in the strip list. This is similar to traditional lighting consoles locate function.

You can manage your media and see what’s active. Up to 255 media items can be loaded.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Video Files (with or without audio)

Most video formats are supported when the appropriate DirectShow video codecs are installed. By default, ELM can play these files: .mov, .avi, .wmv, .mpeg, .mp4, .mp2, .mkv, .webm, .ogv and .ogg. There’s no video size and resolution limits. The audio track is played back on the default sound device. If not needed, you can remove the audio by using the transcode button.

The recommended video format is MPEG4 in an avi file. For smaller files at the expense of a higher CPU usage, you can use H264 in an avi file.

Picture Files

Use images like bmp, jpeg, gif (animated or not) and png.

Effects

The built-in effects give you pixel-perfect and configurable visuals. There are 100+ effects available, each one configurable in multiple ways. Many effect parameters are controllable via the DMX remote.

Capture Devices

Use live videos captured with a video card input or a connected camera like a webcam. Any DirectX/DirectShow compatible hardware and software are supported.

Screen Capture

Capture any part of your screen and use it as a media in ELM. For example, play a video on Youtube and map it to your LEDs. Another utility is to capture your video editor (like Adobe After Effects) preview zone and let ELM generate a LED preview in real-time to assist your content creation. This avoids having to render your video before trying it in ELM.

Screen Capture Dominant Colors

Capture any part of your screen and extract the dominant colors. This is useful to do color matching between any kind of content and your LEDs.

Texts

Generate scrolling text with various fonts.

Spout (v. 2.006)

Use live videos generated by the most common video frameworks and VJ software. This includes Resolume, Ableton Live, Processing, Max/Msp, TouchDesigner, Cinder, OpenFramework, VVVV, Isadora, After Effects, Mapio, Unity3D and more. The Spout integration gives you total control over the content and is the way to go when you want interactive visuals.

Effortless LED Mapping by Enttec ELM User Manual rev 1.42

Network Device Interface (NDI v. 4.1)

Receive live video streams via the network, as commonly used in professional live show productions. Easily connect ELM to a multitude of NDI compatible hardware and software, including capture cards, IP cameras and video over the cloud. NDI has been developed by NewTek - http://NDI.NewTek.com.

MJPEG Streams

It’s the most basic way to receive video streams via the network. If your IP camera doesn’t support the more complete NDI protocol, it should at least support MJPEG streaming.

DMX Bitmap

This special media allows receiving DMX from a lighting console and convert it to a video. You can then use this video like any other media and map it on your LEDs. A common usage scenario is to control groups of LEDs with one RGB or intensity value.

To quickly test your installation without having the final videos, just use the built-in effects. You can create your schedules and test everything right away. Then when you’ll get your videos, replace the built-in effects.

Media file paths are saved relatively to your project file. Use the consolidate feature to copy all files in a directory next to your project. Then copy everything to your other computer.

DVI

Opens a window to output the video to a projector or TV. The position of the window is saved in the project file. You can output the media or the LED map. The LED map is exactly the size of the stage and one LED is exactly one pixel. This is required for systems taking a video input like Martin P3.

You can use ELM to output video to a projector or TV without controlling

LEDs. Simply create a stage and don’t put any LEDs on it. Then in the

live mode, click the DVI button.

Using black and white media allows you to use the color filter and get exactly the RGB color you want as output.

Use the live mode as a monitor to help you see what’s going on while

remotely controlling ELM with another lighting console. You can also open multiple DVI outputs (one per stage) and use them as monitors.

- Use the returned HTTP status code to do proper error handling.

- Addresses and names are case-insensitive.

- Parameters can be provided in the query string or form data.

- Media id 0 is an empty slot.

The base URL to access the API is: http://YOUR-COMPUTER-NAME:port/elm. If you prefer, you can replace the computer name by its IP address or localhost if the server is running on the same computer. The port can be omitted if it’s 80, which is the default for HTTP.

You can restrict the access to the API by activating the Basic Auth feature. For more details see https://en.wikipedia.org/wiki/Basic_access_authentication.

Problem

Possible causes

Solutions

No Art-Net nodes detected in the scan nodes dialog.

The node IP address may be incorrectly configured. For example,

the computer’s IP is 192.168.1.X and the node’s IP is 192.168.0.Y.

The wrong network adapter may be selected in ELM.

The firewall is blocking ELM.

Change the IP address of your computer or your node to be on the same network, that is most of the time, the 3 first numbers need to be the same. The subnet masks (netmask) also need to be the same. Usually, you want to use 255.255.255.0 as the subnet mask.

Go under the settings menu and make sure the proper network adapter is selected for each DMX protocol.

Use the firewall button in ELM.

Output lag/shuttering (working but with intermittent delays).

The network is overloaded, most of the time due to the use of broadcasting. By default with ArtNet, all universes are broadcasted (sent to all connected devices on the network). Some routers and switches may have problems under heavy load. With sACN, multicast is used and may not be well supported by your routers and switches, resulting in broadcasts.

Enter your node IP addresses in the universe boxes to enable unicast sending. For Art-Net, click the scan nodes button and then the configure unicast button (see Art-Net). This greatly reduces the work your router/switch has to do.

Alternatively, you can lower the ELM’s

output rate (see Project).

Another way to reduce the network load is to enable the optimize frames option.

Some lights wrongly stay on for half a second or so.

The most common cause is an unreliable network like a WIFI causing data packets to be discarded.

Missed DMX packets due to a too high output rate and the optimize frames option being ON.

Disable the optimize frames option for Art-Net or sACN. ELM will continuously send data even when

there’s no change. You may need to

reduce the output rate to avoid network overload.

When the optimize frames is ON, ELM

doesn’t send DMX unless there’s a

change. So if your LED controller or

fixture discards a packet because it’s

overloaded, visual artifacts will be visible. Try deactivating the optimize

frames option or reducing the ELM’s

output rate.

The lights do nothing.

The nodes may not be properly configured or not plugged.

The strips may be configured to use the wrong universes and/or addresses.

The firewall may be blocking ELM.

Test the nodes with the configuration utility from the manufacturer. Check the IP address configuration as described above. Check the universes and addresses of your strips. You can use an Art-Net sniffer like the Artnetominator or Wireshark to see what ELM is sending.

Disable your firewall. Use the locate universe feature in ELM to force sending all channels at full.

The lights flicker.

The most common cause of flickers when using LED strips is that the wrong LED type or protocol has been configured in the LED controller. For example, selecting TM1803 instead of WS2811.

Maybe some LEDs don’t have enough power. It can cause flickers at the end of the strips.

This may also be caused by using video content with little noise in it due to compression (may not be problematic when displayed on a screen but it becomes apparent on LEDs).

Some older LED fixtures may not work well when using the Art-Net optimize frames option.

Start your LED controller configuration utility and check the configured LED

type. Try different types if you’re

unsure.

Enable the testing mode (see Testing Tab) and select a low brightness color. This will cause the LEDs to use less power. If the flickers go away, then the problem is due to not having enough power going to

the LEDs. You’ll need to inject more

power.

The testing mode generates a pure

color, so if this isn’t a power problem and a full white test color doesn’t

cause flickers, that means the video content is probably the problem.

Disable the optimize frames option (see Art-Net).

Solutions

ELM isn’t

starting and saying a dll is missing.

Probably the Visual Studio 2015 run-time component is missing.

Download and install the Visual C++ Redistributable for Visual Studio 2015 https://www.microsoft.com/enca/download/details.aspx?id=48145

Very high CPU usage.

The computer can’t handle your

videos.

You are looking at a stage and the computer is having a hard time drawing pretty graphics.

The output rate is too high.

Reduce the resolution of your videos by using the transcode button (see

Video Files). Transcoding can convert to an easier to decode format which may also save CPU.

If you’re using live video capture, try

reducing the capture resolution.

If the computer is already overloaded, try not to unnecessarily leave ELM on a graphic heavy screen. Minimize the ELM window or go in the setting/project tab. Also make sure to close all monitor windows.

Alternatively, you can lower the ELM’s

output rate (see Project).

When moving my project to another computer, the media are missing.

The ELM project file doesn’t contain

the media and the stage’s background images.

You need to move the media to the other computer and put them at the same place relatively to the project file. A good practice is to create a media folder next to your project file. Alternatively, use the consolidate feature of the media library (see Media Library).

I see a blank screen when using a remote desktop app like LogMeIn or VNC.

The ELM user interface uses hardware acceleration (DirectX and OpenGL). Some remote desktop app doesn’t support it or need special configuration.

You may need to configure your remote desktop app to support hardware acceleration. Alternatively, TeamViewer works well with ELM.

The eye candy effects aren’t working on Mac under Parallels.

ELM needs OpenGL 3.3 and Parallels only supports OpenGL 3.2.

Use Bootcamp instead of Parallels.
