May I have some xa sample for testing?

I'm not sure about the issue, sometimes settings are not upgraded after new releases, and ffmpg.exe path reverts to default applicatio path. I made a new change in code to fix it, but no further versiones are expected in the near future. Thanks for the report.

Thanks for your words, it's been years of developmend, feedback and refinement, I hope it keeps on working for a long time. . Good to know you found out the external cause, let's hope for a fix or a workaround.

Hi, thanks for your message. Hace you tried at settings enabling "Preserve timestamps" ? It could fulfill your needs. (Keep source timestamp)

ffmpeg-batch

I guess that adding this could work, but never tried with makemkv bluray output -map_metadata 0

Bluray handling is complex, tried myself and chapters are usually impossible to get with ffmpeg only. You probably need other apps like MakeMKV or tsMuxeR to achieve all that workflow.
