No, this is not an audio-sync complaint!

Hello there,

I have a few older clips that are out of sync. No, they were from elsewhere, not from VideoStudio.

However, I wish to use VideoStudio 11 to repair them.

Is there an easy and direct command that does this (sync, audio delay, audio advance, etc.)?

I'm currently working with a longer solution such as putting the clip multiple times on the timeline, blocking the sound of one, blocking the video of the other, timing them, blah, blah, blah. Ok, it works, but I'm sure there's a quicker process somewhere if someone knows.

Thanks for your help!

Short answer: no. In fact, quite a few users over the years have had precisely the same problem with videos produced *with* Video Studio.

The simple fact of the matter is that Video Studio is a consumer level editing program. It is NOT the sort of specialised mpeg editor required for fixing out of sync problems. A simple program of this type is Video ReDo and there is a trial version of that which can be downloaded. Another more sophisticated program, with a steeper learning curve, is called by the unlikely name of Womble.

There are workarounds for avoiding the problem or dealing with them if they arise with video originating in VS. But they tend to be of the type already described in your 'blah blah' comments!

Thank you for your answer Ken!

Just to comment though. I have been one of the fortunate people using VS that have had ZERO A/V sync issues ever. I could not have asked for a better package.

I am currently trying to repair older MPEG-1 clips that have been butchered by other packages that I used. (Those were my bad days.

)

Yes, I've heard of those packages that you mentioned. Even TMPGEnc does that as well. I was just kind of hoping VS can be my one-stop-shop with this too.

But at least your answer helps in that I can now make a decision whether to continue with the longer "blah blah blah" way in VS, or simply use another program instead of endlessly looking for a VS function that doesn't exist.

Thanks again!

PS: Maybe this could be a nice feature in a future package. I guess, since VS apparently may be guilty of A/V sync for others, it may redeem itelf somewhat.

If it helps the very first thing you need to do it get everything out of a highly compressed format. You cannot easily sync audio that is compressed, so exporting the video & audio separately to different elementary streams is the only reliable method Ive found to work.
I suggest using the DV-type2 elementary streams for the conversions.

Well, for the sake of completeness, and in the event that it may help others here too that are interested, thanks to suggestions here, I'm now using an app (won't mention name on a Ulead forum) that demuxes the video and audio into separate streams.

I then load those into VS and adjustments are as easy as could be now!

Ok, it would be nice for VS to have this feature built-in, but at least I know it doesn't have it and I won't go crazy looking for it. At any rate, with this demux method, I still get to use VS for most of the work, which is what I wanted to do in the first place.

Thanks for all the help!

It might be useful for others to know what the adjustments are that you make once the video and audio streams are split. Also any observations you might have on the difference in the adjustments necessary between the method your are now using, and those which might be necessary if you used VS to split the audio from the video (which was among the work-arounds I mentioned in my first post but did not enumerate).

There is also no reason not to mention the name of the third party application you are using. Lots of us here use a variety of third party programs along with Ulead ones in any one project. And again it would be useful for others to know which one you use for this purpose.

Absolutely Ken,

I didn't realize till you just mentioned it that you can split the video and audio into separate streams with VS. Really? All I see is how to save the audio to .wav, not the original track. How is this done?

Nevertheless, I was using TMPGEnc Plus to do the demultiplexing for me into the two streams, which works beautifully. I use File->MPEG Tools->Simple De-multiplex and input my clip, and the video output streams are the originals:
Video only stream: m2v
Audio only stream: mp2/ac3/wav (depending on source)

I then load (or reload) these streams into VS, place the video (m2v) on the Video Track and the audio (mp2 or ac3 or wav) on the Music Track.

Then, depending on whether the audio is ahead or behind, I "shift" the audio backward or forward with my mouse, and test playback of the project until I get it just right. With a bit of practice, this is very easy and quick.

Once I'm satisfied with the sync/timing, then that's it. It's then business as usual when I save it this way/render/vsp/etc.

Hope it helps someone with sync problems, whether they got this problem with VS or another app like I did before I started using VS.

With a video in the timeline, on the Edit page, you will see on the centre right of screen a series of possible actions (color correction, reverse video etc). One of them is Split Audio. In timeline view, you will see the video on the top line but its audio now appears in one of the two audio tracks to do with as you will.

What is more, there is a back up if your screw things up: in point of fact, this is just a copy of the original audio. The original is still with the video, only muted. So if things go wrong with your cutting or moving the audio track in an attempt to synchronise and you want to start afresh, just delete the audio track, then unmute the video track and start all over again.

You can also right click on a clip and choose Split Audio.

Wow, works like a charm. Very easy. I've actually just completed my little project of several dozen of these clips. Thank you folks!

BTW-Steve, great post on correcting A/V sync issues. Although I've personally never had A/V sync issues with VS, I can see how any app can redeem itself, at least indirectly, from many customer complaints about A/V sync issues if they had a guide like yours for their product. Well done.
