Captured footage corrupted

[gitface]

Hi All

I hope you can shead some light on a problem they we had a work the other day.

We were asked to film and edit a local schools play. For this we used 3 cameras, two fixed and one roaming.

When we captured the footage to computer we found that the footage from one of the cameras was coroupt. The bast way of describing this is that at certain points the picture breaks up into bands. The picture below shows this better.



The camera is a Cannon XM1.
The tapes were new and unwrapped for the filming.
We are capturing through the firewire port of an Creative labs Audigy card.

We have recorded other stuff on the camera after this and the footage was OK.

If anyone can shead any light on how to fix this (highly unlikely if its the tape) and how this might have happeded so that we can aviod it in the future.

Thanks for any help in advance.

I see that on hard drives that are fragmented.

If it is only happening to footage from one camera, then my first guess is that it happened either during recording or playback, rather than being due to a hard drive error.

The problem as pictured looks like what I have seen happen with dirty heads -- which could be either on the record end or the playback end (assuming you used a different deck for transfering the footage to your computer). Have you been mixing brand of tape in either the camera or the deck? Or even mixing types of tape from within the same brand? I would first suggest cleaning the heads on the playback machine and trying the tape again -- or even just fastforward to the trouble spots and see if they've gone away. Or use a different deck/camera to play back and see if it happens again.

If it still happens in the same spots, then there was something happening in the camera during recording, or something wrong with the tape. Yes, you said that you've used the camera since, but that doesn't mean much -- I've seen anomolies like this happen regardless.

And if all else fails, you can just edit around the drop-outs with footage from the other two cameras...
