If this wasn't a dropout, what is it?
just going through some dvcpro50 footage shot on our hvx200, and noticed what appear to be two frames of dropout or other digital glitches. How can this be? Is there a possibility of some other type of interference in the signal (a power surge or other such interference?)?
see attached screen shot of one of the frames. Any thoughts? |

I had something like that on one of the first HVX shoots I ever did. It didn't mess anything up since we weren't going to use that shot anyway so I can't remember if we fixed it by re-importing or if we just let it go and hoped it didn't happen again.
I'd go for the re-import and see what happens. BTW, was this straight from a card into your computer or had it been transfered to a P2 store or something before import?

Clay - I've seen this once in the last six months shooting DVCPRO HD indoors, and it only occurred on one frame, which I deleted in post.

I haven't had a chance to look back into re-importing the media, but I do have all the original files. This was shot directly on P2, then was offloaded from the camera to our edit system via firewire. It's the only such glitch I've encountered so far with this setup, but I will be trying to track down the cause/source so we aren't caught offguard if this happens again at any point.

Clay,
The way to troubleshoot this is if the data is still on the P2 card, then playback that clip directly from the camera out to a large monitor (if you have the ability) or even just the flip-out LCD. If the glitch/dropout is in the clip then there might be a problem with the camera. If the clip is clean in-camera playback, then it could have happened during transfer to a HDD or even during the conversion process from P2/MXF into whatever format you're editing in. If the issue is in the original clip then send the camera to your local Panny repair shop. There have been a very few cases where in-camera dropouts like this were noticed and the Panny repair corrected the issue (don't ask what the fix was, I don't remember - they might have simply replaced the camera). |

Are you using a Mac? Because until today, this problem seems only to occure on Mac's. It's not an FCP thing, it's seems to be more of a mac OS thing.
So before download footage from a P2 card always always always ALWAYS write-protect your card first! Then read this: http://www.dvxuser.com/V6/showthread.php?t=77384 Peter |

This is a Hard Disc issue. Don't bother looking for it on your P2, you will not find it. Check for damaged sectors. Run a defrag, or simply re-transfer the original footage.
