Description

Summary of the bug:
How to reproduce:

% ffmpeg -i input.mov -vcodec r210 -movflags +writecolr output.mov
% ffmpeg -i input.mov -vcodec v210  -movflags +writecolr output.mov
ffmpeg version: N-90169-gf4709f1b7b

In BM Resolve the brightness can be normalized by forcing the color_range to full. There is also a high risk that something with the 32Bit packing is wrong.

  • Keywords color_range removed

Please provide a short input file and the command line you tested together with the complete, uncut console output to make this a valid ticket.

8bpc and 10bpc are working fine! Only the 10bpc exports are showing this behavior.

comment:5 Changed 5 days ago by cehoyos

How did you create 1980p_test_sequence.mov? Do you find it likely that it is supposed to look as in the jpg you provided?

comment:6 follow-up: Changed 5 days ago by wavelet

The 1980p_test_sequence.mov was created with BM Resolve(1920x1080). I took a tiff sequence and used the DNxHD codec. You can reproduce the same results with other sources like PoRes? in mov container too.

The jpg http://projekte.waveletbeam.com/SourceVSR210.jpg is showing the wrong behavior. The left side is the R210 export and the right side is the source material. You can clearly recognize that the brightness ramp on the left side (upper left corner) is much darker as the same area on the right side.

comment:7 Changed 5 days ago by wavelet

Sorry, I mixed up the left and right image. I will exchange the image

comment:8 in reply to: ↑ 6 Changed 5 days ago by cehoyos

Replying to wavelet:

The 1980p_test_sequence.mov was created with BM Resolve(1920x1080).

Are you sure? If the console output you provided above were readable, it would indicate that the file was created with FFmpeg.
