Operating System: Windows 10, 20H2. compilation 19042.1348, with the Windows Feature Experience Pack 120.2212.3920.0.
Shotcut version: 64 bits. Portable. 21.10.31. But the same problem it happens with the portable version 21.03.21. It also happens with an installed version (I can’t remember the version, but it was a 2021 one).
Problem: After trimming a few seconds of the beginning of a video fragment, the audio gets distorted. The distortion lasts a few seconds, and sometimes it also appears in other parts of the same video fragment. When I say “distorted” I mean that a few miliseconds of the audio disappeared or are repeated (like an echo), turning the audio unusuable and very difficult to understand. It looks like if there was some kind of problem with the microphone cable (I can confirm that the video fragment had no audio problem at all). When I undo the trimming, sometimes the problem disappears, and sometimes it does not. This distortion can be heared inside the very Shotcut and in the exported video file.
Repetition: The problem has appeared several times. Indeed, it appears each time I repeat this trimming operation on the same kind of video files.
