When trying to encode an H.264 video and deinterlace to 50 frames from 25 fields. I chose High and L4.2, x264 slow, tune film. Output parameters are 1920x1080, 25i deinterlaced to 50p (inside Hybrid), CRF 20 and passthrough audio.
I've previously encoded files without complaint to High L4.2 directly with FFmpeg. However, Hybrid prompts that "Current avc level needs to be at least: 5.1", though I believe 4.2 is a perfectly valid choice. Attempting to restrict to DXVA hardware support seems to make no difference. Is Hybrid attempting to validate based on incorrect constraints, or is there some added requirement for 4.2 compliance I'm not aware of?
Hybrid generated commandline (I've enabled no other settings):
Hybrid is expanding the -tune film but VBV rates appear to be within 4.2 constraints. What am I doing wrong?
