 Time-Lapse Support
With this release, Time-Lapse is now supported in the Gemini 4:4:4. With Time-Lapse
enabled, the Gemini 4:4:4 receives a continuous video feed from the camera, but only
records one frame every 5 seconds, as specified by a menu option.

SSD Progress Bars
With this release, one can optionally display the SSD Progress Bars. These graphically
display the space used / space remaining on each of the SSD's.

From the ARRI ALEXA User Manual
"Vari flag: When set to "On", the Vari flag marks duplicate images in the
HD-SDI stream. A recorder that supports the Vari flag can detect these
frames and discard them. This makes sure that no duplicate frames are
recorded if the HD-SDI is set to a higher
frame rate than the sensor."

Note: There is no Gemini 4:4:4 Menu Item for the Vari Flag support.
This is by design to ensure that the Gemini 4:4:4 automatically detects
whether the ALEXA is outputting any flagged frames or not. This is to
ensure that is shoot is not ruined by setting the option incorrectly, which
would cause the loss of footage.
Thus, just set the Vari Flag mode or not, in the ALEXA, as desired, and the
Gemini 4:4:4 will automatically configure itself for proper operation, and
preventing the possible loss of footage.

Please allow video to be fed into the Gemini 4:4:4 for at least 10 seconds
for the Gemini 4:4:4 do detect the change in the camera's setting.

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 data will appear to repeat over a 1-second interval.

When Time-Lapse is desired, you will need to set the interval between frames to
be recorded, in seconds, from 001 to 255, in the Time-Lapse menu, and also
enable the Time-Lapse Feature.

A "Time-Lapse" tag is displayed in the lower right corner of the screen when
Time-Lapse is turned on. This feature is available for any camera, recording in HD
(DPX) or ARRIRAW.
Recommendation: If people or animals are going to be filmed during the Time-
Lapse Sequence, an interval of one second is typically best. Otherwise, people
appear to jump from place to place.
