mp3 Audio Desync When Not Starting From Beginning
Posted: Wed Apr 22, 2020 4:42 pm
Hi, I've looked around the forum and the tutorials to see if the issue I'm having has been addressed but it seems it hasn't.
When I play back my show from the beginning the timeline syncs up perfectly with the audio track (it's maybe a couple milliseconds off, but it's close enough for me) but if I play it back from anywhere but the beginning the audio starts sooner than it should.
I recorded this to demonstrate what happens, because I'm bad at explaining https://youtu.be/xULWrFJ1_Ss
In my experiments I have found that the audio starts about 1.34 seconds too soon when starting 46 seconds in, and about 0.67 seconds too soon when starting at 23 seconds, regardless of how many sets are placed inbetween those points. It happens even if I sync the sets using the 'Sync Music' function. It also happens exactly the same no matter what the bitrate or audio quality of the file.
Just now I tried using a wav file instead, and it actually has no desync. This fixes my problems, but I'll still post this topic because it's still a bug that might be good to fix.
I'm on a Windows 10 operating system, using EnVision version 1.8.11.
