APPLE PRORES FORMAT
This section provides general information about recording Apple ProRes files with the camera, including:
The QuickTime file is sub-sampled by Apple ProRes when you select the unsupported
2K Apple ProRes over 120
FPS
Recording Frame Rate.
Recording 4K Apple ProRes is only available:
When recording to Apple ProRes only
When recording to the Apple ProRes 422 HQ or ProRes 422 codec.
QuickTime files have the same metadata that is in the REDCODE RAW files. The metadata is per clip, and not per
frame. At this time, there is no tool for extracting that metadata from the QuickTime files.
You can select any resolution. When recording Apple ProRes, the camera scales that format to the Resolution (2K
or 4K) selected in the ProRes Codec menu. The field of view is maintained in the QuickTime file; the image is not
cropped.
If recording 4K Apple ProRes and the resolution is less than 4K, the image is scaled to 2K.
For more information about Apple ProRes, including the data rates for each codec, refer to the
Apple ProRes White
Paper
