Gemini 4:4:4 Gemini 444 Recorder

Gemini 4:4:4, a revolutionary uncompressed video recorder/player.
Gemini enables videographers and cinematographers to capture at the ultimate video quality, in a small, low-power, lightweight package, at a very affordable price. Gemini features a built-in high-brightness 5.0” 800x480 24-bit LCD touch-screen for monitor and playback, and introduces an industry first - the ability to simultaneously record to two removable solid-state drives - creating instant backups; an invaluable insurance against lost footage, as well as, opening new workflow options.

Gemini records 10-bit uncompressed 4:4:4 / 4:2:2 video in most popular HD/2K/3G formats, including 1080p24 and 1080p50/60, with up to 16-channels of embedded audio and timecode. Gemini has slots for two removable 1.8” solid-state drives (SSDs), enabling recording in either parallel mode (instant backup), or spanning mode (longer record times). Sporting a lightweight milled aluminum case, Gemini is about the same size and weight as the popular SmallHD DP6 monitor, but includes Recording, Playback, Image Processing, Dual HD/3G SDI I/Os, HDMI-Out and consumer level audio I/O; while consuming only 8 to 15 watts of power.

Gemini features S-Log support, with user programmable viewing LUTs, which can be enabled selectively for either HD-SDI output. Flexible recording options, include simultaneously recording native S-Log video to one SSD (for on-line), and the same footage with burned-in LUTs to the second SSD (for faster creation of off-line proxies and/or H.264 video for mobile devices/internet).

A 3D/Stereo (extra-cost) option will also be available, enabling dual-stream recording and playback in a single Gemini unit; creating the world’s smallest, lowest-power, 3D recorder available anywhere. Gemini will record independent left/right channel files, while providing full synchronized playback of two streams as well as side-by-side, 50/50 composite, or anaglyph combinations. Gemini can uniquely output 3D in multiple formats simultaneously (ie side-by-side and 50/50 composite), to aid in camera alignment and monitoring.

Planned future enhancements, include reference image overlay (aka onion-skinning). Users can capture still frames or create their own reference images (custom grid overlays, for example) to mix with live video, using an opacity slider. This feature will enable directors to check the current on-set environment against a previous day’s production, assisting in camera setup and easily identifying anything out of place.

Convergent plans to support all major NLE programs, including Avid, Final Cut Pro, Premiere, Vegas and Edius. Editors have the option to edit in full-uncompressed (transfer time off the SSD to a fast HDD is about 1/3 realtime) or use any of the popular CODECs (ProRes, DNxHD, Cineform, etc). For example, using a modern multi-core processor MAC, the transfer from the SSD and software encode to ProRes, occurs in about ½ realtime (60 minutes of video requires a total of 30 minutes to transfer and encode).

Sample Transfer Configurations
Gemini 444 Recorder

Suggested Seagate GoFlex Adapters
Thunderbolt (Single Thunderbolt Port), Seagate Model STAE121
This is the recommended Thunderbolt model at this time, but this does not allow a second Thunderbolt device to be connected in series.

Thunderbolt (Dual Thunderbolt Port) Seagate, Model STAE122
This device has two Thunderbolt ports, allowing a second Thunderbolt device to be connected in series)
Note: This is a Seagate Desk adapter and we have not yet been able to purchase one to test for compatibility, so please do not purchase one of these at this time.

USB 2.0, USB 3.0, Seagate Model STAE104
This is a reasonable solution for those with a USB 3.0 port on their computer and no Thunderbolt port available.

USB 2.0, USB 3.0 with ExpressCard 34 to USB 3.0 adapter, Seagate Model STAE101
This is a good choice for a MacBook Pro with a ExpressCard 34 Slot and without a Thunderbolt adapter.

Firewire 800 Seagate, Model STAE102
This is a good choice for those with a MacBook without an ExpressCard 34 slot or a Thunderbolt port. The performance will be much slower however, since it is limited to Firewire 800 speeds.

Calvary USB 3.0 Adapter, Model CAUSM2001

Gemini 4:4:4 Recorder and power requirements

Supplying adequate power to the Gemini 4:4:4 is extremely important in achieving a successful experience. Insufficient power, especially during recording, can lead to undesirable consequences including SSD damage or complete failure.

When considering a power source, please remember that the power source must be capable of supplying enough Wattage (Voltage x Amperage) in the worst case (most power hungry) scenarios, which in the case of the Gemini 4:4:4 is during recording (and especially when recording to both SSD's simultaneously). SSD power requirements rise substantially during writing to the SSD’s.

The highest power that the Gemini 4:4:4 ever needs is around 24 Watts and this will only be for a very short while. However, the power source must be capable of providing 24 Watts at all times.

So for example with a 12-Volt power supply, the minimum amperage required to power the Gemini Recorder is 2.0 Amps.

It is recommended to use a dedicated power source for the Gemini Recorder. However, if a power source is shared between the Gemini 4:4:4 and other devices such as a camera or monitor, please ensure that the power source can always withstand the power demands of the various devices at their combined maximum needs.

If the Gemini Recorder is being powered from an ARRI ALEXA, always use the RS output (3-Pin Fischer/Lemo) from the camera with the Convergent Design provided DC to DC converter (included as part of the ARRI RAW upgrade package with the Gemini 4:4:4, or otherwise available from Convergent Design).

NEVER, under any circumstances, use the 12-Volt output, (2-Pin Fischer/Lemo) from the ALEXA to power the Gemini Recorder.

The 12 Volt output of the ALEXA does not provide adequate power, and thus may cause serious damage to the SSD’s.

Regarding transfer of video data from the SSD to a computer:
It is vital to use only an AC-powered transfer station, as provided by Convergent Design.
An AC-powered ESATA Transfer Station and an AC-powered Universal Transfer Station are available from Convergent Design. The Universal Transfer Station comes with a USB 3.0 adapter and Thunderbolt and Firewire 800 Seagate GoFlex adapters are available for other sources.
Never use a USB-powered transfer station, USB-powered transfer stations do not provide reliable power for the power needs of the SSD's.
