Large Red Pixelated Spot in Footage
I am exporting an uncompressed feature-length .mov file in FCP7 and one clip near the end has a giant red pixelated spot on it for some reason (see screenshot).
I checked the source footage and it is fine. The footage also looks fine in the timeline and viewer.
Was this just a one-time fluke that somehow occurred during the export process? Are there any settings I should double check before I try the export again?
The export takes about 6 hours and I want to make sure I do everything I can to fix the issue before trying again.
Any help is greatly appreciated, thank you!

What are you exporting as? Quicktime Movie…self contained using sequence settings? Or are you converting the timeline to something else?
That’s a bad compression hit. What is the source codec of that clip?

Hi Shane –
If memory serves, I converted the timeline and was not using the default sequence settings. Sorry if my memory is not 100%, I made the file months ago and was just alerted to the problem by our distributor today.
I believe the export settings I chose were: Apple Pro Res 422 (HQ), self contained .MOV, 16-bit Integer (Little Edian), Stereo 48.000 kHz 16-bit Audio
The source codec of that particular clip is Apple ProRes 422 (LT), Linear PCM, Timecode
I also exported the file at 23.98 fps even though the original footage was shot at 30fps. Could that possibly be the cause? I’ve read that it can cause weird issues like this…
Would it possibly fix the issue if I just used the default sequence settings instead?

Well, there is all sorts of wrong in exporting a different frame rate then you shot. FCP doesn’t do that properly, even on export. You need to export self contained, using the sequence settings, and then convert the frame rate in Compressor.

Hi Shane –
I just tried exporting self contained, using the sequence settings, and no conversion of frame rate this time. However, the large red pixelated spot on that one particular clip is there again.
The source clip still looks good, so it must be some setting or something in the export process is messing up the final product. Perhaps a color correction setting gone wrong?
Any other ideas as to the cause? Thank you so much for the help thus far!
