Thanks Walter; Very Helpfull 🙂
I agree it’s something within the AE 2020 H.264 codec causing the issue.
I updated to AE2023 & Adobe media encoder 2023. Now I do not have this issue that sound in out of sync from the start of the movie file.
Now I have the issue that I cannot change the FrameRate when using (Adobe’s) Default AE H.264 codec for export (output to an MP4 file). Although my input file is 23.97 fps.
When I select in AE the H.264 codec I can set a lot. Just not the Frame Rate. Which AE (‘due to meet format constrains’) automaticaly changes to 23.976) for which AE even gives me a warning). And that little change of 0.006 is enough to get the audio more and more out of sync (from 0 at the start of the movie to at the end about 6 seconds difference).
I tried to select another output format (AVI) and Codec (do not know which one anymore) and then AE crashed (*) when I started rendering… 🙁
ad (*): ‘Compressor format error’.
I will try your suggested ProRes 422 codec.
I really do not like Adobe tools. When working it gives fine results. But I think Adobe makes it a ‘sport’ to make easy and obvious things: very difficult. And I’m actually only using AE for (Maxon) Magic Bullit Denoiser III (which is excelent AND very easy to use ;-).

Ps.
Sorry for my late reaction. There came something much more important in between.
