.mov file corruption
HI there I have been rendering out a short graphics sequence as a quicktime .mov using AVID 1×1 in After Effects CS5 on a Dell Vostro PC. When this has rendered it plays fine on my computer. I then put it on a flash drive to transfer to an AVID computer but when the file is transferred onto the AVID computer the file has strange green glitches all through it. We are using AVID codecs which have worked before perfectly and I have tried rendering out the graphics sequence a number of times and every time once it copies onto the AVID computer it becomes corrupt. Weirdly if the graphics sequence is played off the flash drive on the AVID computer it plays fine but as soon as it is transferred to the AVID computer is becomes corrupt.
Sorry maybe a bit of a long post for a simple enough question.
Thanks in advance. -

Verify both computers have the same version of the Avid QT Codec. Avid has made many tweaks to the DNxHD Codec in the past few years, and mismatched Codec versions can cause your symptoms.
You say that it plays fine off the USB drive, but not INSIDE avid. Are you playing off the USB drive and playing in Avid on the same machine?
Are you importing the file into Avid, or playing via AMA (Avid 5.0+)?
Is the Avid project at the same frame rate as your MOV file?

The thing is it plays off the USB but if it is dragged from the desktop onto the computer it plays out corrupt. Even if its just played in quicktime player.

I have seen this before. Is it just a few frames or is it entire portions of the video? If it is just small portions, take it off the thumb drive and import to Avid. Sometimes there is latency in some thumb drives which causes a buffering issue during play and import.

Cool thanks, yes it was just the odd frame here and there. I re rendered the sequence and put it on a different thumb drive and all was fine. Do you think that means that the thumb drive which did not work is corrupt and will do that all the time?

I would say that the drive is not capable of “saving” video files. The files are so complex and really require a very steady write speed and access speed, something lower quality and/or older thumb drives cannot handle nor guarantee. I purchased a few from a large chain store and none of them perform like the brand name drives.
Take care,
Jonathan
