Full details of the used files
SUMMARY
After installing kdenlive 20.08.03 i did the exact same (same files, same
mouse-clicks, everything the same) as i my previous version 20.08.01. But the
results of the preview in the timeline get distorted.
STEPS TO REPRODUCE
1. Insert two self-recorded (with obs) mkv files into the projekt. (which works
if edited the same in Version 20.08.01). (File details se Additional
Information)
2. Put both files onto the timeline (one after the other)
3. Cut from the first file on the timeline after two minutes or so and the
delete the resulting first piece.
4. Remove resulting emptynes on the beginning of the timeline.
5. Scrub a little around in the first part of the file and play some seconds
6. go to the end of the first file and let it play til its end
4. Cut from the remaing part of the first file on the timeline 2 minutes or so
from its end. And remove the resulting righthandside piece, and also the
resuting emptyness (You are left with a hugh middlepart of the first file and
the appendend full second file)
8. Move the play position into the first quater of the first file and let it
play for a moment.
9. Than move the play position into the second halfe of the first file and then
the sound gets distorted.
OBSERVED RESULT
The video seems to be played correctly but the sound tracks are distored, wrong
tempo, and kind-of in a loop (a loop of the cut part which was remove from the
end of the first file). This will *not* adjust after moving the play position
around. Speech for example could not be understood anymore.
- In the first half of the first file in the timeline the sound will be played
completly normal, for the second half of the first file in the timeline the
sound is distorted.
- This happens also if the edditing is done in the Kdenlive 20.08.01, saved and
than load again in 20.08.03. After scrubbing to the end of the first file in
the timeline, play and going back somewhere else this phenomenon happens again.
EXPECTED RESULT
In Version 20.08.01 which i'm using again bc. of the bug, the preview of the
timeline would play normal after cutting the file on the timeline. No
sound-distortion.
