Skipping Pictures With AVI DVD Playback...

Post by Mark Out »

I used to capture footage from my DV camcorder using an analog device (one of those RCA/USB composite thingies) but have recently installed one of IEEE 1394 ports in my PC and have started capturing footage in the almighty AVI files. So far I'm blown away by how good they look.

The problem comes when I've created a project in Ulead VS 11 and I'm try burning it onto a DVD. The burning process isn't really the problem, it's the playback. The audio is fine, I couldn't ask for much more where that is concerned.

The problem is the picture. It isn't neccessarily freezing up but it has a tendency to jump and skip. It'll kind of freeze up for a few milliseconds then skip forward. There's no problem with it getting out of time as the lip synching is spot on from start to finish. It's just that the picture skips from time to time.

As an aside note, the picture is fine before it's burned onto a DVD, it plays back pretty good in the project preview window.

Any thoughts? Could it be a RAM problem or perhaps the video card?

Welcome to the forums. If you told us a bit more about your work flow after you have finished editing, it would help get a sensible response. :lol: For instance, do you finish editing, then go to Share > Create Video File > DVD (as we recommend) to first prepare a DVD compatible mpeg-2 file from your original DV material? Or do you edit then jump straight to Share > Create Disc > DVD, and have the burning process do the conversion as part of its own routine (which can often cause problems)?

Indeed, are you even capturing to DV format using your new firewire card, or are you capturing direct to mpeg-2?

Whatever the case, if you are capturing via Firewire, its Field Order will always be Lower Field First, and this must be maintained throughout the whole editing/authoring process. In other words, if you first convert your DV to mpeg-2, whatever other properties you choose for this, it must use Lower Field First. And in the burning process, you must also use the same field order. A common problem if you don't do this is jerky final video, and/or jagged edges on straight lines, especially in fast moving scenes or when panning.

Thanks Ken, it's a pleasure to pick the brains of likeminded people.

You've already solved my problem, its working fine now! What I was doing was capturing my DV camcorder footage into AVI files then was using them unconverted in the timeline. I didn't convert them into MPEG files or anything, I was just using the AVI files to create projects. They would then be converted by the program during the burning process. But since I've converted the AVI files into MPEG files, it's now working like a dream!
