Grass Valley Maestro Master Control v.2.4.0 - Manual (Page 314)

MAESTRO — User Manual 310
Visualization Tool
For HD video:
• 1920x1080 interlaced video @ 29.97, or 25 frames per sec
• 1280x720 progressive video @ 59.94, or 60 frames per sec
These constraints include the video track with the alpha channel encoded
using the Apple Animation Codec (32-bit raster, ARLE encoding); Maestro
will discard any audio tracks that are in the file.
Note The support of the .mov format does NOT affect the maximum animation
durations for either SD or HD supported video standards. That is, the anima-
tion file cannot be larger than 175 MB when converted to the Maestro .mim
format or you will see an “out of memory” alert. The .mim format is an
internal file format that Maestro uses for transferring files to the Maestro
Frame Processor.
