Bug 450449

Summary:	The audio, when rendered with an animation, skips ahead so that it does not correctly correlate with the animation that it's supposed to sync with.

STEPS TO REPRODUCE
1. Create audio file (WAV or MPG3) then add to a new Krita Animation Document
2. Animate something with the audio 
3. Render animation into a video (MPEG4 File?)

OBSERVED RESULT
Instead of the audio that's attached to Frame 0 playing, the Audio from Frame 98 starts playing, meaning that the wrong part of the audio plays at the beginning of the rendered animation. I redid the audio file to make sure, but it seems that any audio I put in, when I render it, it just skips ahead even though it plays correctly in the program.

EXPECTED RESULT
The audio meant to play on Frame 0 playing, so that the audio and the animation correctly syncs up.

ADDITIONAL INFORMATION

Comment 1 Eoin O'Neill 2022-02-17 23:57:48 UTC

I can confirm the bug. Audio is one of the next things we are going to be working on in Krita's animation system so this is actively being worked on. 

Thanks for taking the time to report the bug,
Eoin.

Fix removal of duplicated frames in "Only Unique Frames" mode

The offset was applied incorrectly so the clean-up stage of the rendering
process removed incorrect files (basically, the files without the
normalizing offset)

The patch should also fix a possible offset issue between the video
and audio when rendering multiple times into the same folder
