Something like this can depend on which format and other decisions are made during encoding. And be a bugger to puzzle out, at times. Which gets very annoying quickly.
I know some users have found that ProRes in mxf does a lot better for alpha and for moving between video post apps.
Hmmm... nothing has changed about file format support for Apple ProRes.
It's been awhile since I've exported ProRes 4444 from Motion, but I'll give it try and report back.
Back before Apple deprecated QuickTime, we could simply change the .motn extension to .mov and the file imported into After Effects or Premiere Pro. It's really unforunate that we lost that functionality.
Thanks Warren! I also tested your file and it does work, but for some reason mine doesn't. I did the same operation and same format in AE and it now works, but not in with particualr motion file.
I just had the same problem but found that if I created an Apple Animation file instead that worked just fine and included the alpha as well. Wish Adobe would fix this.
I just ran into this today as a client that edits in Premiere can't open a ProRes 4444 file I've sent them that was exported from Motion.
@Douglas371127185nhm - where are you seeing "Apple Animation" as an option in Motion? I'm running Motion 5.7 for reference.
I solved the problem by opening my ProRes 4444 file in compressor and exporting an OpenEXR Image Sequence, then importing that to After Effects and rendering out a "Lossless with Alpha" file. That works in Premiere.
What a pain. Did Apple break something in Motion exports of ProRes 4444, or did Adobe break something? Either way, ridiculous and needs to be fixed.
Movies exported from Motion on two of my Macs using ProRes 4444 work as expected on the Premiere Pro side; however, with the deprecation of QuickTime as a system driver for time based media, QuickTime moves area now supported at the appliction level rather than system driver level. So... something wonky could be happening.
@Kevin-Monahan Thanks for following up. I found a workaround, and don't anticipate working with that client again, so it's fine with me if you close it. If you want I could send you the file I was having issues with for your testing.
I am also having this issue. I was able to export out of Keynote as Apple ProRes 4444 with alpha just fine, but as of the last couple weeks, my editors can't open the file. Is there a workaround?
@Karen245699667hsh I was working in Motion, not Keynote, and exported it as an OpenEXR image sequence, then imported those into After Effects and exported a ProRes 4444 from it and sent that to my client.
