Choosing an Apple ProRes codec for transcoding REDCODE media
4. Optionally, you can choose a color option from the RED FCP Log and Transfer
plugin submenu of the Action pop-up menu. By default, this is set to As Shot, but you
can choose any other option from this submenu with which to preprocess the
ingested clips. More information about this option appears below.
5. To proceed with ingest, follow the instructions in the “Overview of Transferring File-
Based Media” section of the Final Cut Pro 7 User Manual, found in the Final Cut Pro
Help menu.
Color Space When Transcoding with the Log and Transfer Window
When you transcode RED media using the Log and Transfer window, the raw RED
media is encoded as YʼCbCr image data whether youʼre transcoding to one of the Apple
ProRes 422 codecs, or to Apple ProRes 4444. However, the chroma sampling will be
different:
•
If youʼre transcoding RED media to one of the Apple ProRes 422 codecs (Proxy, LT,
422, or HQ), then the RED media will be decoded as YʼCbCr image data with 4:2:2
chroma subsampling.
•
If youʼre transcoding RED media to Apple ProRes 4444, then the RED media will be
decoded as YʼCbCr image data with full 4:4:4 chroma sampling. Apple ProRes 4444 is
capable of encoding either RGB or YʼCbCr image data, but always at 4:4:4.
Color Processing When Transcoding with the Log and Transfer Window
The Color, Color Temp, and View RED ONE camera settings that were in use during the
shoot are stored as metadata within each recorded R3D file. When you transcode R3D
media to Apple ProRes, this metadata is used to preprocess the color and contrast of
the transcoded media as long as the RED FCP Log and Transfer plugin submenu of the
Action menu is set to As Shot, which is the default setting. The result is that each
transcoded clip visually matches the image that was monitored during the shoot. This
preprocessing is “baked” into each ingested clip. If you want to later reapply a different
type of image preprocessing to a clip, you need to reingest it.
