SUMMARY

STEPS TO REPRODUCE

EXPECTED RESULT
The audio visualization should match the audio and thus be compressed or stretched as well.

Thank you for reporting. Is it the same as this issue https://invent.kde.org/multimedia/kdenlive/-/issues/1050 ?

Similar, but the movement of the audio thumbnail is not the same. My audio thumbnail 

The end result is the same though: the audio thumbnail becomes useless because it does not match the position of the audio signal it is representing any more. sometimes it is simply disappearing in the middle of the track and pushed "together", sometimes it is cropped (although I am compressing the audio into higher speed).

Thank you for the feedback. Let's see if we can fix that in one of the upcoming releases.
