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.
