Introduction

This section describes the FilmStream mode of operation and

outlines the technology used in the Viper. The access and

security features of the camera are also explained.

Introduction FilmStream mode 1-1

Selecting operational mode

To operate in the FilmStream mode you must ensure that the camera is switched to this mode. The output signals and the control functions that are available depend on the mode you select.

The factory default for the mode setting is the FilmStream mode, so normally you do not have to switch modes to operate the camera as a digital film camera.

If a different mode has been set up, then you need to switch to the FilmStream mode by changing a menu setting (for more details refer to Section 5).

To change modes:

1. Open the menu system.

2. Go to the Install menu.

3. Select Output mode item.

4. Change the value to FilmStream or HDStream.

The camera remembers the last selected mode, so it remains in the FilmStream mode even when switched off and on again.

Monitoring

To provide a monitoring signal for viewing, a separate channel is used which undergoes some video processing to make it acceptable for viewing on monitors and viewfinders. Although derived from the same sensor signals, this channel is entirely separate from the main FilmStream output.

The Viper does not have any adjustable visual parameters for the FilmStream outputs. Framing, focussing, exposure setting, shutter angle and optical filtering are the only operations required of the camera and lens operators.

1-2 FilmStream mode Viper

Streaming modes

FilmStream mode

The FilmStream mode differs from the HD video mode in that it captures all information in a scene and stores it digitally without altering any parameters. By avoiding video processing in the raw RGB data, the output signal is a true and faithful representation of the light from the scene. Thus the FilmStream digital data signals are full-range signals suitable for film post-production without any loss of information.

Capturing the light

The Viper uses three high-definition CCD sensors to register the light from the lens. The signals from these sensors are converted to R, G, and B data values using 12-bit A/D converters. Using logarithmic calculations this data is then converted to 10-bit values and transferred to a recorder using a dual HD-SDI link. Full resolution is maintained: true-progressive 1920 x 1080 pixels for every color. No color sub-sampling, no color space conversions, no irreversible video manipulations, no further quantizations, and no compression is carried out.

HDStream mode

The output mode can also be set to HDStream. This mode provides signals similar to the FilmStream signals but in a 4:2:2 HD-SDI format. These HDStream signals are subject to white balancing in the camera but like FilmStream signals, they do not undergo any other video processing. HDStream mode is ideal when storage capacity is limited or for applications where lower resolution signals are sufficient, such as background for keying.

Introduction FilmStream mode 1-3

Technology

CCD sensor technology

The Viper FilmStream Camera uses three unique 9.2 Megapixel HDDPM+ CCD sensors that allow the camera to work in several formats; 1080 lines at 24/25/30 frames per second or 720 lines at 24/25/30/50/ 60 frames per second.

This CCD sensor is based on the Frame-Transfer principle which is best suited for progressive images. The Viper uses a mechanical shutter which means that the CCD exposure has a similar ramp to film cameras, thus providing similar motion characteristics.

Formats

The following formats can be selected in the Install menu:

1080psf at 23.98Hz 1080psf at 24Hz 1080psf at 25Hz 1080psf at 29.97Hz 1080i at 50Hz 1080i at 59.94Hz 1080i at 59.94Hz - 23

720p at 23.98Hz 720p at 25Hz 720p at 29.97Hz 720p at 50Hz 720p at 59.94Hz

The sensor consists of 1920 horizontal pixels and 4320 vertical subpixels. By grouping the vertical sub-pixels, the vertical line count can be set. Full resolution is preserved and the horizontal viewing angle stays the same.

• 1080P

When four vertical sub-pixels are combined, the total line count becomes 1080 lines. So, a 1920 x 1080 image sensor is obtained with a 16:9 aspect ratio.

1-4 FilmStream mode Viper

• 1080i

When eight vertical sub-pixels are combined, the total line count becomes 540 lines. The second field is shifted four pixels to give an interlaced picture.

• 720P

When six vertical sub-pixels are combined, then the total line count becomes 720 lines. So, a 1920 x 720 image sensor is obtained with a 16:9 aspect ratio. When set to 60 frames per second, slow motion effects can be achieved during post-production at different playback speeds.

• Cinemascope Aspect Ratio

When three vertical sub-pixels are combined, 1440 vertical lines are obtained. By using the middle 1080 lines, a 2.37:1 aspect ratio is achieved without the need for anamorphic lenses while maintaining full 1920 x 1080 resolution. There is no need to crop the image or lose resolution to get this aspect ratio.

Introduction FilmStream mode 1-5

Access and Security

Camera cards

Three camera cards are delivered with each camera; one owner’s card and two user cards. An owner’s card is linked to the serial number of the camera and is unique to that camera. It cannot be used as an owner’s card for another camera. The owner’s card acts as:

• an access control device to the security settings of the camera.

• a storage card for four scene files and two operator files. The user card stores four scene files and two operator files.

Operator files contain information relating to the set-up of general camera preferences. Scene files contain information relating to the video settings of the camera head.

Owner’s card

1-6 FilmStream mode Viper

User card

Access control

The owner’s card or the PIN code is used to access special set-up and security features of the camera. Inserting the owner’s card into the camera gives direct access to the Security menu. If you select the Security menu without this card inserted, you must enter the correct PIN code to gain access to this menu.

User levels

Four user levels can be set in the security menu. These restrict access, in varying degrees, to the operational controls. The appendix indicates which functions are available at each user level.

Setting up the camera

Physical set-up

The Viper can be tripod-mounted or operated from the shoulder. Attach all accessories to the camera as described in Section 2 or as described by the manufacturer. Connect the camera to the recording system or directly to the post-production facility.

Power

If using an external power source connected to the power input socket at the back of the camera, switch to the external source. Set the power switch on the left side of the camera to the On position.

Functional set-up

The camera uses an electronic viewfinder. Text messages giving information about the camera status are superimposed on the viewfinder picture. The viewfinder is also used to display a menu-style control system. This menu give access to the camera functions.

When you first use the camera, you should enter the menu system to check and, if necessary select, the operational mode that you wish to work in and to set up your personal preferences. Refer to Section 6 Operating the Menu System which explains how to use the menu system.

The menu system has 3 user levels. If the level is set too low, you may not have access to all the available functions. The owner card or the PIN code is used to set the user level in the Security menu. For full control, set the level to 3.

Mode selection

The operational mode is selected in the Install menu. Check that the output mode item is set to FilmStream. Then select the format you want

- 1080p or 720p. If you select 1080p, you can then select the aspect ratio

- 16:9 or SW (cinemascope).

Lens

5-2 FilmStream mode Viper

When you fit a lens, check the lens documentation to determine how to adjust the back focus of the lens. In the menu system, select the lens type from two predefined settings; standard or wide angle. Choose and, if necessary, adjust the iris parameters to suit the lens and your personal preferences.

Viewfinder preferences

Viewfinder markers, and on-screen display preferences can be set in the VF menu. The zebra overexposure indicators and the focus assist function are also set up in this menu.

There are also several switches and controls on the viewfinder itself for adjusting its functioning (refer to Section 4).

Monitoring signal

To make the FilmStream signal suitable for viewing it undergoes video processing. This is only for the monitoring signal, the FilmStream signal is not affected. Some video parameters can be changed for the monitoring signal. On the camera:

• Gain (-6db, 0dB, +6db or +12db)

• Colour temperature (3.2K, 4.7K, 5.6K, 7.5K or Thru)

In the Video Mon. menu:

• Black level

• Knee compression of highlights

• Skin matrix

Set these preferences to get the best possible picture in the viewfinder and on the monitors.

When the camera is used in the FilmStream mode the only operational

Set-up and operation FilmStream mode 5-3

Operating the camera

functions to be performed are:

• Framing

• Focussing

• Shutter angle

• Internal optical filters (if required)

• Start recording

Framing

Because the picture displayed in the viewfinder (and on the monitors) is directly derived from the electronic signal from the sensors, it is a perfect representation of the captured shot regardless of the position of the viewfinder. (The viewfinder causes no light loss or reflections and does not have to be physically aligned.)

Focussing

A tape measure stud on the lens adapter provides a reference for the optical plane. To assist with optical focussing through the viewfinder, use the VF Zoom button on the left-front of the camera to enlarge the centre of the viewfinder image. A crawler function (that can be switched on or off in the VF menu) adds motion in the viewfinder to objects in sharp focus.

Light exposure

The camera has a sensitivity that is equivalent to a film sensitivity of about 320ASA (400ASA for super wide-angle). Use the zebra function in the viewfinder picture to identify overexposed areas.

The sensitivity of the camera is also influenced by the shutter angle you select.

Shutter angle (exposure time)

The Install menu above shows the items displayed when you first enter the menu and the other items that are available by scrolling up or down with the Rotary control.

Leaving the Systems Menu

If you are deep within the menu structure, follow these steps to leave: a. If necessary move the cursor to the leftmost column with the Select

button.

b. Scroll upwards with the Rotary control until the cursor points to

TOP (this is the Main menu).

c. Press the Select button. The cursor now points to the Menu off item

of the Main menu.

d. Press the Select button to leave the Systems menu. This is the recommended way of leaving the System menu.

If you do not use the menu it disappears after a few seconds. (This delay can be programmed in the VF menu.) However, when you press the Select button again you enter the System menu at the last position of the cursor and not at the top of Main menu. To prevent confusion the next time you enter the System menu, it is advisable to leave the System menu by returning to the Main menu (TOP) and selecting Menu off.

6-4 FilmStream mode Viper

Making changes

To find out where you have to go to change a function, consult the appendix to discover under which menu group or sub-group the function you want to change is located.

If the cursor points to an item (and there are no double arrows to indicate a sub-menu) then the item pointed to has a value. The value can be:

- a toggle value (only two values)

- a list value (more than two values)

- an analogue value (variable from 00 to 99)

or unavailable (---).

If the value is unavailable it cannot be changed. This is indicated by three dashes (---). This can occur, for example, when a function is switched off. The analogue values associated with that function are then unavailable.

If there are only two values associated with the function, then pressing the Select button toggles between these two values.

If a value is displayed after the function that is part of a list, then pressing the Select button places the cursor in a list menu indicating the value currently selected. Use the rotary control to point to a new value. Press the Select button to return the cursor to the function list.

If an analogue value is displayed after the function name, then pressing the Select button places the cursor in front of the value and the rotary control is used to change the analogue value. Press the Select button to return the cursor to the function list.

Undoing changes

If you make changes to the video settings in the Systems menu and you decide not to keep them, use the Std. File button at the side of the camera to recall a standard set of values for the video parameters.

Menu Structure

Access to the functions on these menus is determined by the user level that has been set. The menus are as follows:

Main (top) menu

The top menu gives access to the other main menus.

VF menu

This menu contains the functions which determine how items in the viewfinder are displayed

Lens menu

The functions contained in this menu control various aspects of the lens.

Video Mon. menu

The video menu contains those functions which affect the picture quality of the monitoring signal.

Install menu

This menu contains functions which are used to install the camera into a particular configuration. It also contains controls to customize those switches which are directly operated on the camera.

Files menu

This menu allows function values to be stored in scene files and recalled as required.

Security menu

The security menu is used by the camera owner to set user levels and to control access to the camera, or to store the customer (scene and operator) default files.

Diagnostic menu

The diagnostic menu is designed to provide information on the current status of the camera.

6-6 FilmStream mode Viper

Security Menu

The Security menu provides restricted access to special set-up and security features of the camera. Access to this menu requires the owner's unique camera card or the PIN code that has been set for the camera.

Note:

An owner’s card is linked to the serial number of the camera and is unique to that camera. It cannot be used as an owner’s card for another camera.

Inserting the owner card into the camera gives direct access to the security menu. If you select the Security menu without this card inserted, you must enter the correct PIN code to gain access to the Security menu.

User Levels

The installed user level function in the Security menu restricts access, in varying degrees, to the operational controls of the camera. There are four user levels: user0, user1, user2 and user3. The purpose of the user levels is to restrict the set of functions which can be changed by whoever is using the camera. In this way a more centralized and uniform control can be achieved and the danger of the camera operator accidentally changing critical functions while shooting is reduced. User level 0 is a special protection level which locks most of the operational controls of the camera. Use this level to ensure that a camera that has been set-up is not tampered with. User level 0 is not normally used for operational purposes. The appendix indicates which functions are available at each user level.

PIN Code

The PIN code of the camera can be viewed and changed in the Security menu. The camera's PIN code when it leaves the factory is set to 0000. It is strongly advised that this code be changed by the owner on receipt of the camera. This ensures added protection against unauthorised access to the Security menu.

Using the Menu System FilmStream mode 6-7

Files Menu

Files Menu Features

A user of the LDK 7500 camera can have access to 15 different files. This number can be extended by using additional scene file smart cards. The Files menu is used to recall and store these files.

There are two types of file; scene files and operator files. A scene file contains values related to the picture performance. The operator file contains values related to the set-up of the camera (viewfinder, lens and installation parameters). The appendix indicates the functions that are stored in the scene file and those functions that are stored in an operator file.

Scene files

Four scene files are stored in the camera itself (SCAM1, SCAM2, SCAM3 and SCAM4). Another four scene files can be stored on the smart card (SCARD1, SCARD2, SCARD3 and SCARD4). The default file names can be changed in the files menu. A STANDARD scene file (preselected as either factory or customer defined) is stored in the camera.

Note:

The standard customer scene file is stored via the Security menu, not the Files menu. The decision to use the factory defined file or the customer defined file as the standard file is also made in this menu.

The Files menu enables the scene files to be stored and recalled using the store and recall entries of the menu system. If the message NOK is displayed then the old values are restored. If the camera is recording when a scene file is recalled then the recalled values do not become active until the camera stops recording.

Operator files

The Files menu also allows the recall of the opererator file stored in the camera (OCAM1) or one of the two operator files (OCARD1 and OCARD2) stored on the smart card. These files contain information for setting up the non-video configuration of the camera.

6-8 FilmStream mode Viper

The default file names can be changed in the files menu. A STANDARD operator files (factory or customer defined) is stored in the camera.

Note:

The standard customer operator file is stored via the Security menu, not the Files menu. The decision to use the factory defined file or the customer defined file as the standard file is also made in this menu.

Standard customer file

The green button on the side of the camera recalls the standard scene file. This file contains standard parameters for the picture performance. A standard operator's file can be recalled via the Files menu. This file contains parameters for the set-up of the camera. A customer standard can be defined for the standard scene file and for the standard operator's file. The contents of the customer files for both these standard files is stored via the security menu. The selection of a factory defined or a customer defined file for use as a standard file is also made in this menu.

Introduction HD video mode 1-1

Selecting operational mode

To operate in the HD video mode you must ensure that the camera is switched to this mode. The output signals and the control functions that are available depend on the mode you select.

The factory default for the mode setting is the FilmStream mode, so to operate the Viper as a HD video camera you have to switch modes.

You switch to the HD video mode by changing a menu setting (for more details refer to Section 5).

To change modes:

1. Open the menu system.

2. Go to the Install menu.

3. Select Output mode item.

4. Change the value to either R, G, B or Y, Cr, Cb depending on the type of output signal you require.

The camera remembers the last selected mode, so it remains in the HD video mode even when switched off and on again.

1-2 HD video mode Viper

HD Video mode

Viper cameras support a full-resolution digital RGB (4:4:4, 10-bit) video mode output over dual-link HD-SDI. You can also choose two HD-SDI YCrCb (4:2:2, 10-bit) video mode outputs via single HDSDI cables.

In these video modes, in-camera video processing is provided with detailed adjustment options. The camera has all the video-processing tools of modern video and digital cinema cameras including adaptive knee functions, matrices, gammas, black stretch, and coarse and fine detail circuitry.

All other features that Viper FilmStream Cameras have to offer (such as multi-format capability) are still available in these video modes.

Formats

The following formats can be selected in the Install menu:

1080psf at 23.98Hz 1080psf at 24Hz 1080psf at 25Hz 1080psf at 29.97Hz 1080i at 50Hz 1080i at 59.94Hz 1080i at 59.94Hz - 23

Introduction HD video mode 1-3

Technology

CCD sensor technology

The camera uses three 2/3-inch sensors that offer superior performance and ultimate flexibility. The sensors have a high dynamic range and high linear sensitivity across all camera lens apertures. These unique

9.2 Megapixel HD-DPM+ CCD sensors allow the camera to work in

several formats; 1080 lines at 24/25/30 frames per second or 720 lines at 24/25/30/50/60 frames per second.

This CCD sensor is based on the Frame-Transfer principle which is best suited for progressive images. Frame Transfer technology also ensures that there is neither lag nor smear. The Viper uses a mechanical shutter which means that the CCD exposure has a similar ramp to film cameras, thus providing similar motion characteristics.

Formats

• 1080p

When four vertical sub-pixels are combined, the total line count becomes 1080 lines. So, a 1920 x 1080 image sensor is obtained with a 16:9 aspect ratio.

• 1080i

When eight vertical sub-pixels are combined, the total line count becomes 540 lines. The second field is shifted four pixels to give an interlaced picture.

• 720p

• Cinemascope Aspect Ratio

When three vertical sub-pixels are combined, 1440 vertical lines are obtained. By using the middle 1080 lines, a 2.37:1 aspect ratio

1-4 HD video mode Viper

is achieved without the need for anamorphic lenses while maintaining full 1920 x 1080 resolution. There is no need to crop the image or lose resolution to get this aspect ratio.

Digital video processing

The advanced digital video processing of the camera is based on 12bit AD converters and more than 22-bit internal processing. Two DSPs combine all major camera functions in the digital domain, including knee, gamma, contour, matrix and colour correction.

The intelligent continuous automatics facility provides automatic control of black levels and black shading. Each sensor provides black reference signals that are used to monitor temperature changes. This means that continuous automatic correction is applied without operator intervention.

The digital contour processing uses full amplitude 400% video RGB signals via an extended dynamic range contour circuit. Colorimetry is selected by means of a variable 6-point digital matrix or via preset matrices. Digital gamma circuits provide a wide range of standardised gamma curves and enable soft contrast in black scenes to be enhanced, together with hard contrast and saturated colour in bright scenes. The matrix and gamma sequence is software programmable for precise colour matching.

Film-like characteristics

The pivoting knee circuit adapts both the knee point and the compression ratio according to the highlight content of the picture to emulate the softly limiting S-shaped transfer characteristics of film. Digital True Colour Knee circuitry maintains the correct hue for compressed highlights, reproducing colours faithfully, even overexposed skin tones.

Digital contrast circuitry provides a black stretch function for more detail in black areas and a black press function for improving the contrast impression by simulating the S-curve of film.

Microphone

2-12 HD video mode Viper

To attach the optional microphone (AJ MC700) to the camera proceed

as follows: a. Open the microphone holder by unscrewing the knurled screw (2)

of the microphone support bracket (1) on the viewfinder and open.

b. Slide the microphone into the split tube until the microphone

shoulder reaches the mark (3) in the tube.

c. Place the tube with the microphone into the holder with the split

facing upwards.

d. Ensure that the rubber supports at the back and front of the holder

fit into the rims (4) around the tube.

e. Close the holder and tighten the knurled screw at the top. f. Connect the microphone cable to audio connector (6) (mic) on the

right side of the camera.

g. Place the microphone cable into the top clip at the front of the

camera and into clip (5) at the side of the camera. Pull and twist clip (5) to open it.

Other microphones with a diameter of 21mm can also be used, however, ensure that the phantom power and the sensitivity of the input that match that type of microphone are correctly selected in the camera systems menu. Refer to Section 6 for more information on selecting the audio inputs and controlling the audio level.

Note:

• When longer microphones are used, it is not necessary to place

them in the split tube.

• For optimum operation, the microphone should be mounted as

straight as possible.

• Don’t allow the wind hood to touch the holder (7) as this reduces

the damping effect.

• By placing the split facing upwards, the microphone cable does not

touch the holder thus avoiding mechanical pick-up.

• The microphone can also be connected to the rear of the Triax

adapter where a switch selects the input. Refer to Section 4 for more information on connecting the microphone to the rear connector.
