I've run into two, similar problems on the attached project.
Video 2: ProRes 422 (converted), 5760x2880, 25fps, 128kb/s - 48kHz
Video 1: Simple MP4 h264 100 mbit SDR files (....001.MP4 and ....002.MP4), 3840x2160, 25 fps, 128kb/s - 48kHz
Audio has been normalized.
Video 1 contains two files, one continuous recording split in two (by camera). Both valid.
This cannot be aligned, because of file "...002.MP4".
Note, that both leading audio tracks are rendered in exactly (?) half the space, required.
Selecting "Auto Align Clips" and "based on waveform", leads to this organisation, that is obviously wrong:
Repeating "align" alters nothing. But now the waveform is rendered correctly in size (25fps?), but alignment is off (as if audio is displayed based on 50fps).
Now, when I try to align the tracks manually, initially the audio tracks "loose" the vaweforms - making adjustment impossible - but after a bit of "movement", vaweforms turn up again.
After a repeated alignment, this is the new - weird - result:
Seemingly perfectly aligned on audio vaweforms, but now the vaweforms display only occupies half the required size (audio is fully present in clips). Again!
Somehow, it looks as if DaVinci Resolve assumes 50 fps, when aligning and displaying audio, although the time base/frame rate really is 25fps.
Project UHD, 25 fps. Project created today.
Extra audiofiles were not requested to be aligned, but when they are, the result is also "weird". The individual audio files, seem to be synced as expected (between the audio files only), but not in any way aligned to the audio in the video.
Version 17.4.3 (10) Studio version, Monterey 12.1.
Any ideas? I'll create a new project based on the material and add the result to the thread later.
Regards

- Note: Audio vaweform rendered too short (factor 2)

- Audio now rendered correctly, but sync/align still not successful.
