FCPX 10.2 not recognising transparency in ProRes 4444
on May 1, 2015 at 3:01:46 am

Since the latest update to 10.2 FCPX has spontaneously begun having trouble recognising transparency in Apple ProRes 4444 files. The transparent elements are appearing as solid black on the timeline. I've tried rendering and exporting the timeline without success. I don't use proxy media and transcode the majority of my video and audio files.

What was up until now a perfect workflow for me is now causing me lots of grief. Any ideas as to how ProRes 4444 might be playing up in FCPX since the update?

Thanks
Curtis

Thank you for the link to the similar thread. I've found that I must start selecting 'Alpha Add' in the video settings for each ProRes 4444 clip on the timeline, which fixes the problem with transparency/alpha.

However, it's inconsistent as another video transition that I just exported worked automatically as soon as I brought it back into FCPX (without me having to set the composite mode to Alpha Add). It's strange that this has a) suddenly become an issue, and b) is an inconsistent one.

Thank again.

It looks like this problem was fixed in 10.2.2

I just did a quick test on my system and I can't replicate this problem. What else could be going on I don't know.

It's seems to be super specific and Devin figured it out in the other thread.

To sum up:

- All alpha movies from Ae work.

- alphas from Motion work if the clip starts with full transparency.

- Alphas from Motion don't work (without the Alpha add) if the clip starts with full opacity. Fcpx will not let you override the alpha settings, it constantly defaults back to an alpha of 'none'.

Weird - because it works fine for me either way.

Even though these clips with alpha I'm exporting from FCPX, you think it's the same problem as alpha from Motion? Come to think of it, the clips that aren't working do begin with no alpha in first frame...

I did a test to replicate this but it also works fine for me either way.
