Go to about 4min in this video to see how FCPX is handling/interpreting the alpha you are giving him.

Have him toggle the alpha handling setting to see if that fixes the alpha for you. If it does great!To export b/w alpha matte pass:
Go into UltraKey and change “output” to “Alpha Channel”. This will give you a black and white alpha matte pass. Export the clip.Jeffrey Di Lullo

If the alpha isn’t looking correct I’d ask 2 questions:
1) how is he interpreting the alpha: premultiplied or un-premultiplied. Then make sure that it matches what you are outputting.
2) Can his system correctly read the Cineform codec. Have you tried sending the clip as ProRes 4444?
Larry Jordan recently wrote an article about Cineform and FCPX (Not sure how helpful it is in your situation as it doesn’t directly relate to keying). https://larryjordan.com/articles/problems-with-final-cut-pro-x-and-gopro-cineform/What would it look like if you just sent over a black and white alpha matte of the keyed clip and the original clip (two clips) and have him use that to key in FCPX. You can render the alpha matte pass as PhotoJpeg or a PNG sequence or whatever you like. Considering that he wants to finish the composite in FCPX this would actually give him better control over the final composite and would be my preferred method.

If you are asking which ProRes flavor to use, I’d say you’d be very happy with ProRes LT for this job.

I believe that codec was from the old cinewave hardware. Not sure that you are going to be able to open it without the cinewave codec.

Thanks for the post. I will try to get it upgraded (I am not the admin).

No problem! I’ve used these to deliver a TV spot that was shot in 720p23.98pN (HVX200) which needed to be delivered in 29.97. It worked like a charm. Just to remind you this preset will create an interlaced video file.

I don’t remember which thread it was on the cow that I pulled these from (if someone can find the orignal thread please post it), but here are the compressor presets to create a ProRes file with correct pulldown.
They need to placed in:
~/Library/Application Support/Compressor
Once there make sure the restart Compressor (if it was already open).
Good luck!

Check out AutoMotion. If you read your post correctly this will fill you need exactly.

I think you need to change your render settings. If you go to the sequence menu in the tool bar you’ll see entries for render all. Select it and go to the sub-menu. You’ll see a list of colors. Each of these represent a type of RT effect (dark green being Full RT and orange being unlimited) You need to check each one that you want the render command to render. You have to do this one at a time. Your motion clip is going to be an Orange render.
Once you’ve check the correct render colors (hint: I have all of them check for “render all”), hit render and it should go.

Rob,
Were you playing back a 720p60 sequence or 720p23.98 sequence?
