Description

example SUDS mov file

example AvidRGBPackerHD 1080P RGB file

notes: (maybe useful)
Avid DS produces SUDS quicktime ref movies which playback on windows (avid ds platform)
however avid does not provide codecs for mac.
this is what you can do to playback SUDS file on mac:

  1. download avid quicktime codecs http://avid.custkb.com/avid/app/selfservice/search.jsp?DocId=423319
  2. encode any video using quicktime with AvidRGBPackerHD codec
  3. replace stsd atom of your dsproduced.mov with stsd of avrpencoded.mov - now your DS video plays back in quicktime7. which hopefully proves that AVrp and SUDS are the same codecs.

example of DS output and hacked stsd to enable mac playback files are provided above.

mov contains some visual.(color,contrast,tint,brightness) atom stuff which is not currently supported.
So I think that is causing difference and not bug in AVrp decoder.

You could modify values of such entries in mov to prove me wrong/correct.
