1. Always record to the INTERNAL MEDIA OF THE CAMERA; this is critical for proper
timecode and ideal for dual media / backup.
2. DO NOT PULL POWER OR MEDIA (SSD, SxS, CF) from the unit or your camera during
record or playback; This may result in data that is unrecoverable.
3. Power and Cabling: Make sure you have PROPER POWER (6-19V DC), plugged in to
the proper power spigot (left side of recorder), and that 3G-rated SDI cables are
used.
4. Familiarize yourself with the equipment and test prior to shooting.
5. Before using the SSD’s it is IMPERATIVE TO FORMAT them in the Gemini 4:4:4.
Formatting SSD media is a DESTRUCTIVE PROCESS; all existing data will be lost during
format.
6. Ensure that the camera’s viewfinder data is not being recorded; IF YOU SEE VIEW
FINDER DATA ON THE GEMINI 4:4:4 monitor, then it will be recorded!
7. NEVER DELETE ANY FILES OFF AN SSD FROM A COMPUTER, except when going
through a firmware update procedure.
8. While we recommend that you always maintain the latest firmware on your Gemini
4:4:4, we DO NOT RECOMMEND UPDATING IF YOU ARE IN THE MIDDLE OF A
SHOOT.
9. When offloading media, ALWAYS MAKE A BACKUP COPY, ideally to a RAID1.
10. GENLOCK YOUR CAMERAS; this is recommended in all multi-cam shoots,
and critical in 3D.
11. Ensure to allow Gemini to finish closing a Record file before taking any further
action.
WARNING! WARNING! WARNING!
Use a Convergent Design AC-Powered Transfer Station ONLY! Do not use the first generation
USB-powered, or any other USB-powered transfer station. Do not use any other 3rd party
transfer station; this could compromise the data on your SSD media.
READ ME FIRST!
Before you begin using Gemini 4:4:4, we strongly suggest you review the included Quick

FEATURES
The Gemini 4:4:4 is a professional, high-definition video recorder that fits in the palm of your hand
and is easily mountable on your camera. It is very light weight and small in size.
Gemini 4:4:4 functions as a high-quality monitor, with a wide viewing angle, high brightness with
great contrast, and no compromise video playback device.
The footage from the Gemini 4:4:4 can be easily incorporated into virtually any workflow using your
favorite codec or as native uncompressed DPX sequences.
With an extra cost option, Gemini 4:4:4 is also capable of recording, combining, and playing back 3D
video.
The Gemini 4:4:4 records to specially certified and tested 1.8” solid-state hard drives that can be
purchased from Convergent Design through your local dealer.
UNCOMPRESSED 4:4:4 RGB, 10-Bit, AND 12-Bit QUALITY
The Gemini 4:4:4 records in the highest quality possible; no other recorder exceeds the image
quality of the Gemini 4:4:4!
The Gemini 4:4:4 records Full Uncompressed 4:4:4 RGB and also accepts 4:2:2 camera signals. This
ensures that 100% of the quality of your video signal will be maintained. There are no signal losses,
no artifacts, and no loss of quality whatsoever.
This is especially important when recording Log video, such as Sony S-Log or LogC. The precise values
for each bit are recorded. No bit values are changed in any way, thus preserving the full integrity of
your images. Recording full 4:4:4 is the proper way to record S-Log and Log-C. Recording 4:2:2 from
a 4:4:4 capable camera is a compromise.
ARRIRAW OPTION (paid firmware upgrade)
Gemini 4:4:4 is ARRI Certified, supporting ARRIRAW (.ari) 2048 x 1650, up to 60fps from any ALEXA
model camera 16:9, and supports 4:3 up to 48fps with desqueeze. Supports full raster live debayer
monitoring and playback, including LUT support. No new hardware, no new SSD’s required – simple
firmware update with paid upgrade.
CANON 4K CINEMA RAW OPTION (paid firmware upgrade)
Canon Cinema Raw (.rmf) support for Canon C500, up to 60fps for 4K, 120fps 4K half-raw, and
120fps HD. Includes 4K, Quad HD, Raw, Half Raw, 2K, 12-bit (1080p) and 10-bit support. Full raster
debayer monitoring and playback (up to 60fps)
STEREO 3D SUPPORT (paid upgrade)
Gemini 4:4:4 supports 3D DPX Record/Play with multiple Combining options and Horizontal Flip
options from 2 Gen-locked cameras up to 1080p30. Combining applies to Live Preview or Play, for
Record the 2 Video Streams are recorded separately (without combining). Horizontal Flip of Left or
Right Channels, applies to Live Preview and to recorded data. Live/Record Horizontal Flip of Left or
Right Channels options are available via menu items:

PLEASE NOTE:
The Gemini 4:4:4 will record from either a 4:2:2 or 4:4:4 camera.
A 4:2:2 signal will be up-resed to 4:4:4.

Choose any of the above for the built-in LCD and HD-SDI A Output. A separate choice may
be selected for the HD-SDI B Output.
DUAL-CHANNEL RECORDING (via 3D Option)
With the 3D Option, you are able to record two cameras simultaneously; Camera 1 to SDI A and
Camera 2 to SDI B. Depending on your settings, you can see both channels for preview/playback,
one separately, or Camera 1 on the Gemini and Camera 2 out to a monitor. *Cameras MUST be genlocked.
4:2:2 to 4:4:4 UP-CONVERSION
The Gemini 4:4:4 records in DPX file format, an industry standard for high end post processing. To
conform with widely used software that accepts the DPX file format, the Gemini 4:4:4 automatically
up-converts (up-reses) to 4:4:4.
This is accomplished by using a sophisticated routine that uses the weighted average of nearby
pixels to ensure that the 4:4:4 is of high quality, even when the source video is 4:2:2.
SPECIAL RECORDING CAPABILITIES
Time-Lapse, Vari-Frame, Project Frame Rate and high frame rates (up to 60fps) are all supported.
HD TOUCH SCREEN FOR RECORD AND PLAYBACK
The Gemini 4:4:4 is easily controlled using the touch screen. A Stylus is provided to prevent the LCD
Monitor from being smudged.

DUAL SSD
The Gemini 4:4:4 is unique in that it supports two SSD’s for both recording and playback. To extend
recording time, a recording can automatically span from one SSD to another. This is fully automatic.
S-LOG and LOG-C SUPPORT
Many features are built into the Gemini 4:4:4 for supporting Log footage:
A menu option easily allows one to apply a built-in LUT (Lookup Table) to native S-Log footage.
The LUT is applied to the LCD and HD-SDI outputs.
LOG RECORDING
The Gemini 4:4:4 is ideally suited for recording Sony S-Log, ARRI C-Log, and will support
Canon Log-C.
SINGLE LINK 3G & DUAL LINK 1.5G/3G
The Gemini supports both single link 3G and dual link 1.5Ghz HD-SDI Input for 4:4:4 and ARRIRAW
recording, as well as Dual 3G for recording ARRIRAW 16:9 48p, 50p, and 60p (4:3 support up to
48fps). Note: Canon Raw 2K 1080 formats only require 3G single link.
HIGH PERFORMANCE SSD’S
The Gemini 4:4:4 SSD’s are specially picked for their performance and reliability. These SSD’s are
capable of read speeds of 500 Mbytes/sec, making transfer of files very quick. You’ll find these
Convergent Design SSD’s available through our Dealers at affordable rates.
FAST BOOT TIME
You can expect your Gemini 4:4:4 to power up and be ready for recording in approximately 12
seconds or less after applying power.

Vari-Frame Support
Gemini 4:4:4 auto-detects Vari-Frame mode from the ARRI ALEXA, and records only the Vari-Frame
video frames. A “Vari-Frame” tag will be displayed on the LCD during Live Preview.
(**Note: When using Vari-Frame, if the ALEXA's Sensor rate is ever changed, cycle all video inputs
to the Gemini before proceeding. )
(**Note that the Live Preview on the Gemini of Vari-Frame data will not look as expected. The
Gemini plays the last 1 second of captured Vari-Frame frames, so that the video and timecode will
appear to repeat over a 1-second interval. )See Release Notes at end of this document for more
details.
If “Sensor Rate” on the ALEXA = 30 or less, “Rec Out” must = 30 or less.
DO NOT set “Sensor Rate” to less than 1.
DO NOT set “Sensor Rate” to 23.98 and “Rec Out” to 24.
DO NOT set “Sensor Rate to 29.97 and “Rec Out” to 30.
“Sensor Rate” must be less than, or equal to, “Rec Out.”

PREPARATIONS
TIPS, TECHNIQUES & RECOMMENDATIONS
The Gemini 4:4:4 is a sophisticated, technologically advanced device. A few simple tips, techniques
and recommendations can help ensure a successful shoot.
1. Register your unit now, as you need access to the Internet to do so.
It must be registered. Otherwise the unit is disabled.
2. Obtain the Gemini 4:4:4 and all the necessary batteries, chargers well in advance of your shoot.
Please be certain to plug the power cable into the power input, which is on the left side, the
remote control connector is on the right side. Forcing the power connector into the remote
control connector will damage the Gemini 4:4:4.
3. Obtain genuine Convergent Design SSD’s. No other SSD’s will work in the Gemini 4:4:4.
This is to ensure that the SSD’s are fast enough and have been fully tested prior to your shoot.
4. Extra, high quality HD-SDI cables are very desirable and should be available on every shoot.
These must be good quality 75 Ohm cables with true 75 Ohm connectors. SDI cables rated for
3G SMPTE 424M are always preferred.
5. Please read the manual, you will gain a lot of practical knowledge.
The latest version is on our website:
http://convergent-design.com/LinkClick.aspx?fileticket=CdmSeL04O18%3d&tabid=139
6. We generally recommend that you use the latest firmware.
http://convergent-design.com/FirmwareUpdates/Gemini444.aspx
7. Test the unit and the SSD’s, with your camera, in advance of the shoot.
Setup your camera, exactly as you will for the shoot, setup the Gemini 4:4:4,
create some test footage, and run this test footage through your Post workflow.
Ensure that your Post department can handle the full uncompressed workflow.
Full uncompressed video is great, it is just different. Many systems support DPX and ARRIRAW,
but not all. Please see the Workflow page on our website.
8. For editing DPX Files using Final Cut Pro, please obtain GlueTools.
http://gluetools.com/products.html Select “Cineon/DPX Pro for Final Cut Studio”.
9. Obtain a way to back up your data in the field. A good backup procedure is to have two
backups, stored on separate devices, and have all of your footage checked visually, prior to
reformatting and reusing the SSD’s.
10. Purchase enough SSD’s, plus some extras. Be certain that you have enough so that you can
shoot while the backups are being made and the footage is being checked.
11. While shooting, during breaks, playback you footage, from within the Gemini 4:4:4 to check that
everything is working fine. But, more importantly, transfer you footage to a backup, then play
the footage from the backup to ensure that all is good!
12. Feel free to call, Skype or email Support 24/7. We strive to provide world class support. If you
don’t reach us at one number, try another.
Support Contact Info: See Page 40.
13. Ensure that camera viewfinder data is not being sent to the Gemini 4:4:4.
Record a test, and then play it back. If you see viewfinder data while you are recording, or on
playback, please turn off OSD (On Screen Display), otherwise this will be recorded in your files.
14. Do not use Beta firmware for production work!

15. Do not over-tighten the ¼” x 20 or 3/8” x 16 screws. You can damage the case.
16. Please do not open the Gemini 4:4:4 case, as this voids the warranty.
17. Here is a tip to help your shoot be a success:
The most successful teams plan ahead, and check out all of their gear in advance.
18. Never format an SSD unless you are certain that the footage has been transferred, and checked.
To be safe, wait until you have the footage in two places.
19. Never attempt to write files to the SSD, nor delete files off the SSD and then reuse the SSD in
the Gemini 4:4:4.
20. It is acceptable to upload files from an SSD, using our Transfer Station, then reinsert the same
SSD into the Gemini 4:4:4 so that you can continue shooting. But, as noted above, do not delete
files off the SSD, then attempt to shoot more.
21. Always format the SSD’s, in the Gemini 4:4:4.
Formatting an SSD in another device is not acceptable.
22. Never put the Gemini 4:4:4 in a confined enclosure, it needs access to fresh air for cooling.
23. Never leave the Gemini 4:4:4 in hot sun without protection for an extended period of time. If it
has been in a hot car, please allow time for it to cool.
24. Protect it from rain, splashes and other inclement weather.
25. Do not leave the Gemini 4:4:4 flat on a table with the power on.
A vertical position is best as it allows air to flow naturally over the cooling fins.
26. Do not feed the Gemini 4:4:4 reverse-voltage DC, or voltages over 19 Volts.
Do not plug in the Anton Bauer D-Tap or P-Tap connectors in backwards.
Caution: Some non-Anton Bauer P-Tap power outlets allow the P-Tap or
D-Tap connector to be plugged in backwards.
If you do, then the Gemini 4:4:4 will stop working and it will have to be repaired.
27. Respect the Touch Sensitive LCD. Do not use hard objects to operate the touch screen.
A ball point or other pen should not be used. Use our provided stylus or something similar.
Caution: The Touch Screen and LCD are expensive to replace.
28. For ARRI recordings using Camera Trigger, recorded .ari files base name will match ARRI ALEXA
internal recording clip name, provided that the ALEXA and the Gemini are set to the same date.
29. If set for ‘Camera Trigger’, make sure camera is not already recording (DPX or ARRIRAW).
