Hello!
I'm trying to compress many of my videos using Hybrid. They are originally recorded using x264vfw with Ultrafast preset, No tuning, High 4:4:4 Profile, CRF 23 and Zero Latency. The color matrix is lossless RGB (Bandicam - "Prefer RGB colorspace", x264vfw - "Keep input colorspace").
The resolution of all videos being 1360x768, Hybrid autodetects the color matrix as BT.709, but the output video has its colors off, whether or not I select the High 4:4:4 Profile again.
What I would want is to preserve the RGB color accuracy and have a final video with the BT.709 color matrix.
Is that at all possible?
