FLV audio out of sync, can't work VirtualDub w/ FLV plugin

[ZantarV]

I ripped a series of videos from YouTube whose audio was out of sync (synced at the beginning, but growing out of sync by about 3 secs at the end of each file) with the intention of syncing the video/audio. I found an "FLV Input Plugin" for VirtualDub (using 1.9.5), got it in a pack and put it in the VirtualDub-1.9.5-AMD64\plugins32 folder. Doesn't let me open FLVs.

You can try flv extract and then open the avi in virtualdub.

And if it's h264 video you can try avidemux to resync it.
