--- Comment #4 from gdorn_...@circuitlocution.com --- Ah, I did not realize that the bug tracking system was not set up to ingest email. I did extensive testing and attempted to send this on March 11: Yes, I just tested on Kdenlive Version 25.07.70 and found the same result - the thumbnail for the second audio track is incorrect. Master is showing an additional bug, though - at some zoom levels, the second half of the thumbnail is simply blank. Sometimes when previewing it'll populate the second half, and then if I change zoom levels the thumbnail changes somewhat randomly, though never representing what is actually being played. I re-tested the same file on 24.12.2 and it does not show this behavior, just the thumbnail being wrong, so whatever change is in master may actually be worse at this. More details regarding the original bug: - It doesn't appear to be codec-related. I thought might be caused by the Opus codec, but I have some MKVs containing two Opus tracks that produce the bug, and some that do not. It may relate to length; I'm still looking for a file shorter than a half hour that exhibits the bug. - The thumbnail appears to be shifted left by 7-8 seconds, at least in this one test case. If I compare the audio track in audacity, both it and kdenlive play the sound at the right time, but kdenlive's thumbnail looks like the sound should have play about 7-8 seconds earlier. When the master version doesn't exhibit the additional instability bug, that offset is consistent across versions. -- You are receiving this mail because: You are watching all bug changes.
