In a facetious post on the videohelp forum I sought help to which I received good suggestions which proved Avidemux is at fault. This bug is so bad and significant I thought I was going a bit crazy. Essentially, Avidemux is broken before it even starts an edit. mpg files which work and sync AOK in all common players such as VLC, MPC-HC etc., (and edit fine in other editors) play out of sync in Avidemux-even in the view mode before an edit is commenced. These bugs have to do with audio/video sync of. There are very significant bugs in Avidemux 2.6.6 and 2.6.7 (I've not tested earlier versions). Time code source : Group of pictures header Typical MPEG file properties for files that Avidemux 2.6.x cannot audio sync: Which also proves there's nothing essentially wrong with any of these MPEGs. It edits perfectly without a trace of out-of-sync audio on these MPEGs. (Buy a cheap program such as VideoRedo. This means that if one uses Avidemux, then even the simplest of edits has to be done manually using the offset, which is a real pain unless you've a clapper sync point (which is not often the case on TV/PVR programs).įorget Avidemux, there's just far too much wrong with it!
The audio is out of sync by at least 350 to 500 ms (depending on file). Yet, Avidemux 2.6.8-even in its 'player mode' (before any editing)-plays every one of these MPG files completely out of lip sync. (That's to say media players such as MPC-HC, VLC, MPlayer, WMP, et al, play the files perfectly-i.e.: with absolutely NO audio/lip sync problem but AFTER they're edited with Avidemux all these players play them with the audio out of sync.) Peculiar, because I cannot find a single media player that actually plays these MPG files incorrectly in their unedited form! However, after the simplest Avidemux edit, they're all stuffed! This is a truly serious bug in Avidemux, and a peculiar one at that.
MPG audio sync bug is STILL NOT FIXED in this version (see my review for 2.6.7 below). Well, despite Avidemux 2.6.8's long list of bug fixes, the TV/PVR.
