[FFmpeg-user] -vf Colorspace filter - 'Unknown input primaries 2' error

[Kieran O'Leary]

Hello,

I want to transcode a DCP to ProRes or x264 while transforming to bt709. I am experimenting with the colorspace filter, as I've found that most DCPS that I've converted have low contrast and washed out colours. As some DCP players (EasyDCP) allow XYZ -> bt709 transforms, I wanted to see if forcing bt709 would produce more satisfactory images. Clearly, I am not very knowledgeable when it comes to colour spaces, so any feedback is greatly appreciated.

I noticed that the colormatrix filter requires that both input and output colour matrixes are specified, but I understood from the documentation that the colorspace filter does not require this.

Here is my command: ffmpeg -i /Volumes/Stardom/kieran_tests/input.mxf -c:v prores -vf colorspace=bt709 /Volumes/Stardom/kieran_tests/output.mov




ffmpeg -i /Volumes/Stardom/kieran_tests/input.mxf -c:v prores -vf colorspace=bt709 /Volumes/Stardom/kieran_tests/output.mov

I have also tried

ffmpeg -i /Volumes/Stardom/kieran_tests/input.mxf -c:v prores -vf colorspace=all=bt709 /Volumes/Stardom/kieran_tests/output.mov


but I got the same error.
Thanks!

-Kieran.
