When outputting uncompressed video, some clips turn black.

Hello Everyone!

Thank you very much to anyone reading this. I am going a bit crazy here and am already past my deadline.

I am making a sort of "slideshow" to a classical music concert on FCP7. So I have a music track from the sound engineer all finished and am editing still tiff photos to this with zooms and cross fades. I am making 4 separate films like this - each its own sequence but within the same project.

3 sequences work fine, but the 4th is having a big problem:
Some clips come out black when I output an uncompressed video. And it varies a bit which one it is, although they tend to be towards the end. Sometimes the sound is there and sometimes not. When I just output again these individual problem clips as uncompressed, they come out fine. It happens when it is the whole sequence that the problem comes.

I have opened a new sequence and copied and pasted everything into here and it still happens. Again the other 3 movies which are set up the same way are fine.

Any suggestions??

Thank you very much!!
Kind regards,
Robert

with all your various exports of the problem sequence,
do you have enough to build a whole one?

can you just re-export the problem areas, then patch the black holes?


another thought:
can you export as Prores, rather than uncompressed?
