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.”
