right, i'll try to keep this as short as possible... i've got a digital TV card that receives digital TV through an aerial (antenna on the roof). it can capture MPEG-2 at 720 x 576 (PAL) which is 16:9 anamorphic. sometimes it's interlaced and sometimes it's progressive depending on the channel...
so i can press record on the TV app and it captures away and after about half an hour, stop it, and it ends up with a massive mpeg file about a gig big!
play it back in media player and it recognises it's widescreen and corrects the aspect ratio... nice. all audio in sync and all video looking amazing...
but as soon as i try and edit it the sound jumps out of sync. here's a few things i've tried...
1) cut in TMPGEnc (MPEG Tools) to just the material i wanted... audio ends up a few seconds off. just re-checked it and it seems to be offset by the same amount all the way through...
2) convert to DivX by using DVD2AVI to make a .d2v file to use in GordianKnot, and an .mpa audio file (stripped out) to rename as .mp2 and disk-write in winamp to .wav to use in GordianKnot... this shows a delay of 550ms apparently... but when i try to correct with this or any other amount the audio will be perfectly in sync for a while then suddenly jump out of sync and stay that same amount offset until it jumps to another offset...
any ideas on this?
it's not going gradually out of sync... the audio and video seems to be at the same rate
i've converted loads of stuff before with all sorts of different offsets and rate differences including stuff captured from camcorder so i'm just a bit stuck with this...
can anyone help me out?
