Project Frame Rate Support
With this release the Project Frame Rate can be set, which will be noted in the recorded
file. This allows the Playback Frame Rate (the Project Frame Rate) to be different from the
Video Input Frame Rate.
For example, a video input with a rate of 59.94 Frames/Second can have a Project Frame
Rate of 23.98, so that Playback from the Gemini (and Editing/Grading Software) will treat
the recording as 23.98, thus causing the footage to be played back in slow motion, (with a
2.5x slow motion ratio).

ARRI ALEXA Vari Flag Support
If the ALEXA
Vari Flag
menu option is on, and the ALEXA
Sensor Frame Rate
and
Rec Out Frame Rate
are set to different values, (with
Rec Out Frame Rate
set to a
value less than
Sensor Frame Rate
), then the Gemini auto-detects that
Vari Flag
is
enabled, and then only records the desired frames from the Camera, bypassing
the frames that should not be recorded.
A “
Vari Flag
” tag is displayed in the lower right corner of the screen when the
Gemini detects
Vari Flag
from the Camera. Available for both Alexa HD (DPX) and
ARRIRAW (.ari) Recordings.
