Bug Description
Binary package hint: pitivi
What I'm experiencing is a bit similar to Bug #578530, I couldn't decide if it's duplicate, I leave it up to you.
I was replacing the audio track of a video with a higher quality mp3. The mp3 was longer, so I put several static images at the end, with a fade-in, fade-out effect on the beginnings and the ends.
The preview was played correctly in Pitivi, but the resulting file was unsynchronized already. What is REALLY WEIRD is that when I tried to play the half-ready file during the rendering, it was STILL correctly synchronized. The tracks only slid away later. The ready and correct beginning of the video later changed for some reason!
Possible reasons:
1: transformed waveforms, how it is described in https:/
2: there was a problematic part in the video - a video track fading away and then a static image fading in. Sometimes in this part the rendering paused for a while (maybe some overloading). This part was never rendered correctly. See my next bug with the video itself. The slide could have happened in this part.
3: or the program can't handle properly multiple video tracks at the same time (one static image or video fading away and another one fading in, that cover each other).
Thanx

To correct myself:
in 1: I didn't mean "changing waveforms", but the non-fluent move of the scrollbar during the rendering, that could possibly affect the correct counting of the actual position.
Sorry, it's late now...
