Video jumpy

I'm using Movie Studio 4 and made a movie that's around 40 mins long. I rendered it and burned it to DVD using DVD Architect. When I play it on my DVD player the first 10 minutes or so are fine but then the video gets very jumpy. The audio plays correctly. Does anyone know what the problem might be? I was thinking maybe it could be the DVD media itself as it is a relatively cheap brand but I've copied DVDs before using that brand and they played fine in my player.

Is it just one DVD that's got this problem or have you tried burning the same movie more than once? Does it play OK on the PC? If you copy the files to your hd do they play ok there? Or if you "prepare" the DVD so that it's written directly to the hd?

Is all your original video from the same source or have you used a mixture? If it's a mixture, is there any connection between what you used and the jumping? Is there a lot of movement in the jumpy bits?

Sorry it's all questions!

And the most basic question -- what are your source files?

Jumpiness and flickering video are common symptoms of videos created from MPEGs rather than DV-AVIs.

Thanks for replying. It's old footage that I copied from VHS using a video capture card (DVD Xpert Maker Video Capture Card/Burn DVD/MPEG 4,2,1). I'm not too up to date on the formats and terminology but the name suggests it captures in MPEG. In fact when previewing in movie studio it is flickery.

Is there any solution I could do as I've a lot of editing done?

If not, is it possible to convert the captured (MPEG) files to AVI?

If not, I pressume I'll have to buy a new video capture card that captures in AVI. Can anyone recommend one? My video player only has SCART outputs.

Thanks!!

If recapturing is a pain, and you don't have too many MPEG clips, then the below may be feasible. Might want to try with just a couple files to make sure it works before investing lots of time!

You might try converting the MPEG files to DV-AVI; you could use Movie Studio to do this. (Import the MPEG files onto the timeline, and render each out using "Make Movie" to DV-AVI.) Make sure you choose a loop region by double-clicking on the event on the timeline, then specifying "render loop region only" when making the movie. This is important since you'll want the new DV-AVI's to be the exact same length as the original MPEG files.

Once you've done this, make a copy of your Movie Studio project file. Move all your MPEG source files to a new place. Now when you open your copy of the project file, your MPEG files will be "missing" and Movie Studio should allow you to specify a replacement file. Specify your newly-generated DV-AVI files. Assuming the new DV-AVI clips are the exact same length as your original MPEG files, then this should work.

Are AVI and DV-AVI the same?

>Are AVI and DV-AVI the same?

No. AVI is a set of rules e.g. you must use constant bitrate audio. An avi file is a file whose contents follow those rules, but that still leaves a lot of flexibility - it could be DivX, DV-AVI etc. avi files are usualy written / read by a codec (coder / decoder) but there are lots of different codecs and there's no guarantee that codec A can read something written by codec B.

Going back to your comment about getting a card that will capture in avi - I suppose you could get one that captures as DV-AVI, but it's not guaranteed.

Are you getting dropped frames? Are you using a TBC and a decent semi-pro VHS playback unit (e.g. JVC 7-9000 series)? It's often hard to get good results from old tapes without these.
