Is there any way to prevent Avidemux from converting a 10-bit BT.2020 video to 8-bit when not using Copy mode? I need to re-encode to fix non-IDR recovery points but even using NVENC HEVC Main10 the output still looks super washed out and I think it's 8-bit. I know this isn't an issue if you use copy mode and then play it with LAV filters, but I would like it to be able to play correctly on other devices like TVs. Using ffmpeg concat to re-encode with libx265 correctly preserves 10-bit but it also drops some frames at cut points while avidemux does not (also avidemux is just so much easier to use).

This would require a lot of work to implement this capability, slightly short of a full rewrite of the entire application (meaning also internal libraries, all video filters and many encoder plugins). Very much wanted, sure.
Thanks for letting me know, is this planned for the future? Avidemux is such a great software for frame-by-frame editing and seems to be the only program apart from ffmpeg that supports VFR output when re-encoding, which is very useful to me, so I hope it can support 10-bit eventually.
