Captured Video is scrambled

Hello everyone,

Has anyone ever captured DV video form their camcorder and found that it is scrambled when you put it in the timeline?

It doesn't happen all the time, just some of the times!

The problem is when I have to capture a video that is 1 hour long I have to wait that whole hour to see if the video got scrambled! So far the last two hours I have captured 2 hours of scrambled video and this is getting ridiculous!

System info:

P4 3.0 GHz with HT
1.5 GB or RAM
Vegas 6.0d installed
Radeon 9700 pro graphics card.
Windows XP Home edition (SP2 installed).

Thanks,

Steve

Can you post an example somewhere or describe more detail about what the video looks like?

Is it scrambled if you play it back in Windows Media Player?

The video looks like there are numerous purple blocks and major drop outs all the time. The video tape plays back fine so it isn't a problem with the DV Media.

I can get the video to play back on Virtual dub without the scrambled look, but the video looks like 1/3 of the bottom is a solid green color for some reason.

If the tape has been used multiple times or has "unclean" data on it, it may be that some hash in the signal is confusing the video capture app. Try starting capture in stable video- this usually solves the problem.

I have also had this problem. Not always, but 1 out of 10 times, the video seems to get really badly scrambled and the audio is bad. No sign of that during capture since the tape plays fine (even new tapes). I'm getting to the point where I generally make sure the camera is wall powered and that I've restarted my computer before capturing. Seems to prevent the issue.

Some playback devices seem more prone to this than others, as well. My panasonic camera does this frequently when capturing, especially when performing an autocapture. My Sony camera has only done it once. The sony moderator is correct in that it is less likely to happen if you are starting with a clean signal, IE. give the tape a pre-roll of 7 seconds or so and manually punch in your in and out points.

Had the same problem once.

I captured... everything looked just fine of wedding service i had on there (bran new tape btw)... Got to editing that section few days later.. TOTALLY hosed vertical lines on other craZy stuff.

Recaputred tape... everything was fine (after i already ruined a nice pair of sweatpants thinking i didn't record the wedding)

I was using a Canon Cam as playback/caputre device....

Not very happy with Canon right now & think my issue might be shared with others more than other name brands...... Did you mention what u used to capture?

Two suggestions:

(1) Download the trial version of ScenalyzerLive and try capturing with that. Lots of us here love this utility for numerous reasons.

(2) Borrow or buy an alternate Firewire cable.
