camera signals. This ensures that 100% of the quality of your video signal will be

This is especially important when recording Log video, such as Sony S-Log or
Log-C. 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

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.
