problem joining AVI's and sync

[deadpool2e]

hi,

this is my first post to the forum so please be kind.

i have 2 avi files and i have joined them with vdub but on the completed file the appended part is out of sync (audio) be about 1 second??

any ideas how i can join the 2 parts without this happening as they both work ok on there own.

Thanks

Using AVISynth you can add individual delays to multiple clips that you've joined.


ex:

AVISource("whatever_1.avi").DelayAudio(-.200)+AVISource("whatever_2.avi").DelayAudio(-.700)+AVISource("whatever_3.avi").DelayAudio(-.400)

etc, etc, etc...

Thanks for that, but why does it throw the sync out when both parts are ok in the first place??

also if i use AVISynth how do i find out the exact delay??

i would rather use vdub as it is easy to jion the bit?

thanks

I join the two with an avs script and then load it into VDubMod. Then check the length of the video and audio tracks of the combined file. If there's a difference, I start with that as the delay on the clip that's out of synch. You're just going to have to fiddle with it till you get it right. Files don't always mesh so smoothly. I've done this a few times with SVCDs I've downloaded and put on DVD, and the second file is usually out of whack, even though it plays just fine by itself. If there's a definitive fix for this, I sure as hell don't know it....I just **** with it till I get it right.

Or at least I used to....before the new wore off and I got tired of screwing around with downloaded clips.
