Hi, newbie here. First, I apologise if this isn't the right place to ask but I found no solution searching other topics.
The video in one of my files is out of sync with the audio. The video is running at a slow 15 FPS in the original file, so the audio finishes a long time before the actual video. I changed the FPS to around 24 FPS which syncs the video and audio but only in the beginning of the video, when a lot further into the video it goes out of sync again...
I think the problem is that the video is slowed down, but not equally slow over the entire video. I can either sync the beginning of the video, which causes the later part to go out of sync (video too slow) or I can sync the later part, which causes the beginning to go out of sync (video too fast).
Also the original file is a DivX file, I already converted some copies to AVI, MPEG,... but they all have the same problem.
Is there any way I can fix this?
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays! or rip iTunes movies!

I thought so already, I'll see if I can salvage some parts by messing around with the FPS.
Thanks anyway for the quick response. -

Method 1 (after DV AVI capture)
- Open AVI in VirtualDUB
- Go to video - Framerate and then select adjust audio/video to framerate (in my case always 25.002)
- Save AVI (video: direct stream copy and audio: direct stream copy)
Maybe if you try the same method above with the 24fps video, change to 24.002 play around maybe it gets in sync.
I don't know wich format the video is, but you can use Directshow plugin https://forum.videohelp.com/topic348265.htmlThe flag once raised will never fall! -

24 * 5825 / 5818 ~= 24.0288759
So you would set the video fps to 24.0288759.
