Video gone funny

I have a project that part way through about twenty mins in to the video it goes all zig zag and seems to stutter, this is all the same file and was captured at the same time. If I view the same file in windows media player it plays fine. Anybody any ideas on a fix.

Vegas 5
WinXp Pro Sp2
1.5 gig ram
Footage Captured with Scenealayzer

I've got the same problem Flak. I got footage that I captured and 75% is fine but some of the clips appear completely screwed up in Vegas - both in preview and in the timeline, yet Windows media player plays the clip with no problems. I've done a search on here and it sort of been covered but with what seems to be more complicated situations behind it. I dont think this is such a "newbie" question at all, and has ground my project to a halt.
Good luck

minna415 did you also capture with Scenalyzer?

No, mine was captured into Vegas using Vegas. But just to make sure that it wasnt the program, I tried capturing it in Premiere Pro and the exact same thing happen to the clips at that point in the tape. So this is obviously something to do with coding and is over my head. I dont understand how windows media player can play the clips fine, but these high powered software's cant. Very frustrating.

If it happens at the same point every time it's an equipment problem, most probably the source. How are you hooked up? Remember that SP2 has a firewire fix that you have to download separately.

Yes I have just rendered to new track with that section thats bad and its the same as before, but if I view it in WinDVD or Cyberlink it plays fine. This is a strange one..

My source is Sony DRC hc-40 running firewire straight in. never had any capturing problems before. Does it have something to do with the starting frame timecode offset?

All my jaggies and stuttering appears when there is motion in the scene, as soon as the camera pans or the person in the shot moves quickly thats when I see them. It can't be anything with capture because it would all be the same. Anyway I captured all the footage on my desktop pc and this is showing up on my laptop.
I will try it on my desktop when I get home because I have just upgraded it with new CPU, mother board and memory and have not tried a project through it yet.

I can try and recapture the footage on the new system and see if the fault is still showing.

Your'e viewing this on a computer monitor right? Have you viewed this on an external monitor (TV)?

This could simply be an issue of playing an interlaced video on a progressive monitor.

Yes I have even burnt the file to dvd and viewed it on my 36 " TV and it looks even worse...

Hey Guys I have found the problem, it was a rouge keyframe for slow mo, it was way down the time line. I only spotted it when I expanded the track view, those dam gremlins again.. thanks for the help and suggestions..

Glad you found the answer and thanks for posting on what you found out.

I guess what was most confusing me is that you said you could not see this when played using WMP. I imagine now that you must have been viewing the original (source) files using WMP and not the one that you had rendered? Or maybe something else was going on here. Interesting.

When I posted I was only abale to try this on my laptop, but when I got home and stuck the project on my desktop I could then watch the output on my monitor, like I said it looked ok in WMP on my laptop, but it was still visable only slightly on my home setup even through WMP. Thats what got me looking.
