Corrupted transitions
on Mar 2, 2014 at 8:46:18 am

Hi,

I'm editing the following sequence

1920x1080
Compressor H.264

and when I export it as QT movie using

Apple ProRes 422 (HQ) 1920x1080 30p 48kHz

the video looks good but all the transitions (mainly cross) look corrupted. For example in some I can see a flash, in others strange skipping frames.

Any ideas why?

Thank you
P

If you edited with H.264 media in FCP, that is probably the reason. H.264 is not an edit format in FCP. You should convert to ProRes before the edit. Try that with one or two clips and see how the transitions look.

Yeah John, I suspected that as I had other troubles.

I'll give it a go. Thank you so much!

BTW, best way to convert from H264 to ProRes?

Thank you

I usually use Compressor, but MPEG Streamclip also gives good results. I have Sorenson Squeeze 9, but have never tried it for this. I suspect it'd do a good job, too.
