Re: Videos are not in sync with the audio

You have not posted a proper problem report, so the best I can do is speculate. To learn
how to post a proper problem report, click this:

You'll probably want to bookmark that for easy reference. I recommend you read that
entire thread, if not now, eventually. As you read through that thread, you'll come
across a couple of references to how to post a proper problem report. A couple of
references. Two of them. You can skip quickly to those references by doing a string
search on "problem report" in there. Click both links, read what you find, then follow
the advice. To post a proper problem report, use the Reply all button. DO NOT USE the

In the absence of a proper problem report, I can say that audio being slightly out of
synch with video is not a big deal. When you play your downloaded video back in VLC (you
should be playing it back in VLC & if you're not, then switch to VLC), it is trivially
easy to adjust the audio to be a little earlier or later than what you're getting. The j
& k keys do the adjusting. Experiment with them while your video is playing. Find a
segment that is clearly out of synch but which will let you verify when you've got it in
synch. My favorite is the swish of the golf club & the sound of the club head hitting
the ball. You might also find a spot where somebody's face is visible on screen so that
you can clearly see the lips moving. That will let you synch the audio well. Press j or
k once or twice, then rewind, then replay the segment. You'll probably have to hit a
key, rewind, & replay a few times before you get the audio synched up. But I can tell
you from experience that this works very well.

I have observed that once I get the audio & video in synch, sometimes they go out of
synch later in the video. This is especially true of recorded livestreams that last 2
hours or longer. I don't know what does this. Livestreams are transmitted in chunks so
maybe the synch is different in different chunks. Oh well. I just go through the synch
process again.

Now if you're talking about synch being off by 30 seconds or more, that's unusual. But
my golf recordings are typically off by about 150ms. The audio is usually ahead of the
video. But I have noticed that this is true when I just watch the broadcast through my
cable box, not using my computer at all & not recording it with VDH. So what VDH records
is a faithful copy of the original source, including its bad synching of the audio with
the video.

If you want to have a more relevant conversation here, you have to post a proper problem
report. It's up to you.
