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).
The Gemini 4:4:4 Kit, which includes the recorder, 1.8” SSD to eSATA
transfer station, AC power supply and cables, housed in a
custom-fitted hard plastic case

Notes
|
1080p29.97/30
and 1080p50/59.94/60 data must be striped across
both drives, so simultaneous recording / 3D is
not supoorted for these formats. (Data from two
SSDs can be readily combined for editing). Also
1080p50/59.94.60 only supported in 4:2:2
sampling. |
