just tried cqp and it looks pretty much lossless to me. gonna be using this now. Thanks for the help!I dont know of any timeline software for windows who does. TMPGEnc VMW 6 supports a bit more, but so far no lossless h.264 either.
Avisynth obviously could handle it.
Or use Constant Quantizer @ Factor 1, which is still 99% lossless and of course 100% lossless for the eye
Videoplayer you have much easier times.
Just use MPC-HC and it will work.
