Can't set H264 CRF to 0 - sharkeylaser - 24.07.2025

When attempting to generate lossless but compressed output with H264, I cannot set the CRF to 0. The UI only allows setting CRF to 1, which is lossy.

Hybrid version 2025.05.18.2 running on Windows 11.

CRF 0 makes no sense.
Using x264, setting 'Encoding mode' to 'constant quantizer (1-pass)' and selecting a 'AVC Profile' like 'High 4:4:4' or 'None', I can enable 'Lossless' which sets '--qp 0'.
