Clip out of sync when I move it to the timeline

[Zeusus]

Hello,


Describe your problem:

Properties of your source files (format, file size, where did you get it?):
Dvd rip, avi file, 712,222kb, downloaded from a torrent. NB: movie plays fine on media player etc, problem is only when editing.

What devices are involved and their mode of connection?:
No devices

Project Settings (important):
I haven't altered any at all. After having the problem I opened up a whole new project and started again without altering any settings as I thought perhaps that was why it was out of sync, but to no avail.

Output format (file, DVD, VCD, SVCD):
Trying to render it in PAL dvd (16:9)
PAL or NTSC:

Error Codes (if any):
no error codes

I'm using Ulead video studio 10.

I'm trying to cut a film file into 2 parts and sort of shuffle them around. However, a portion of the film which I have cut, about an hour long, when I select it in the video area on the top right and watch it on the left (before dragging it to the timeline) it plays perfectly.

However, when I drag it to the timeline, select it there and watch it above left, the sound is totally out of sync most of the time, although sometimes when I start it it's in sync, but when I render it, it's always out of sync.
The opening sound to the scene is usually about 2 or 3 seconds long, but for some reason, after transferring it to the timeline, when you play that clip, the opening sound of the scene is dragged out and is about 5 or 6 seconds long.

I thought perhaps it just plays funny on Ulead but when it's rendered and played on a media player it will be fine, but even after rendering it is still totally out of sync.

I have tried recutting the clip, but that hasn't changed anything. Strangely, the first part of the film is fine and completely in sync, so I thought perhaps the hour long part is screwing up because it is being added to the first part so I've tried rendering it on its own also, which hasn't helped either.

Ideally I'd like to have the reshuffled clip all in one file, but as it isn't working, if necessary, I can have the 1st part (30 mins long and in sync) separate from the 2nd (1 hr long and out of sync).

I'm not great with Ulead and don't know a ton about it, but can someone please help me and explain if I have a setting on or something?
The reason it seems to be out of sync is that Ulead seems to drag out the opening sound to the scene once the clip is in the timeline, even though I haven't changed a single setting from default, so that the audio part of the clip is delayed.

Argh, please help me!

Hello and welcome!
It is very hard to formulate any meaningful answer due to the lack of information you have provided.
Scroll to the top of the page you are viewing and click the "Profile" button. Fill in as much of your system specs as you possibly can. That gives us at least some kind of idea of your computer.
Then, go to this link and read what is needed. Otherwise it is all just guesswork on our part. The important points are the file properties of your video. You can get that by right clicking on the file inside VS. Post the properties back here so we can see what you are dealing with.

Okay, I've filled out all the info. except my motherboard, don't have a clue how to find out what motherboard I have and I've googled it but it hasn't helped. Sorry, I'm not particularly great with computers

[Zeusus]

Okay, sort of realised what the problem is but don't have a clue how to fix it still.

When I select the clip in the timeline, the sliders on the video screen on the left move along about a third to the right and "clip" is highlighted in blue. When I play it when it's like this, it's in sync.

When I then go to share to try and render it, the slider moves back to the beginning (on the video screen), "project" becomes highlighted instead of "clip" and when I try and play it, it's out of sync.

I think your problem has as much to do with your workflow as anything else. Please read this thread about Audio/Video Sync Issues.

The properties you posted of the file look like you just right clicked in Windows.
Please open VS, then right click on the thumbnail of the file in question and note the full properties.
I know you posted "avi" as the file but that could be any of about 80 different types of file.

Okay, sorry, I didn't realise how much info. I needed to put, apologies, hope I've done this right:

AHA! DIVX! DivX is a highly compressed format that is meant for viewing, not editing. Some people have success by first converting this to another type. I believe they use a program called Super. Do a search for DivX for more info on this topic.

[Zeusus]

Ahh, okay, what file type should I be converting to though?

What's ideal?

Thanks!

[Black Lab]

What's ideal? For editing purposes, the ideal format is dv-avi. It's a high quality, mostly lossless format, meaning the quality won't degrade during the editing/rendering process.

Next would be MPEG2. It is a lossy format, but not noticable until after several renderings. However, some people have certain problems when editing MPEG2s (out of sync issues, macro-blocking, etc.), yet some don't.

I'm not sure what Super (or other conversion apps) can or can't do, as I've never used one. I'm sure someone else will jump on board and give some more input.

Although DV format is indeed probably the best format for editing and quality purposes, in your particular case I would definitely NOT convert your DivX to DV, particularly if you ultimate intention is to burn to DVD. DivX is a highly compressed format, DV is a very much less compressed format. In uncompressing DivX to DV, the conversion program in effect has to invent a hell of a lot of data. In other words, the converted format (DV) would not be of the same quality as the original. Then, if you wanted to burn a DVD, the DV would have to be converted yet again to mpeg-2 format which is the international standard format for DVDs. And that is a lot more compressed than DV, so in this case, the conversion would involve throwing away a lot of the data, which means a further loss in quality.

In other words, if you intend to burn a DVD, then convert from DivX direct to DVD compliant mpeg-2 and that way you have only one level of quality loss.

You can download SUPER from www.erightsoft.com/SUPER.html Once that conversion is done, needless to say, you can test it to see if the audio is in sync.

The problem is that, as BlackLab has said, mpeg-2 can be a difficult format to edit (though perhaps less so than DivX!). If you are forced to edit, cut or anything else that requires a further re-encode of your mpeg-2 and the audio gets out of sync again, then make sure SmartRender is not used as that seems to be a source of out of sync problems for some users.

I will mention as a possibility the fact that an increasing number of DVD players are rated to detect and play CDs and DVDs which have DivX files burned to them as data files. So if you have such a player and don't intend to distribute your movie to others (who might not have a DivX rated player), then you could try editing in the original format and simply burning the end product to CD or DVD as data files.
