Adobe media encoder rgb alpha

I'm rendering a rather large video file in After Effects, with effects on top of green screened elements, and it seems like I'm runnning into a lot of bugs with the Primatte Keyer plugin.

I'm on an M1 Mac Studio running Ventura I've seen people say "hardware encoding" needs to be selected in Media Encoder Just black where there should be transparency. What am I doing wrong? When something goes against file format specifications, like having transparancy in a HEVC, it is often referred to as "out of spec".

My 2 questions are: What is the right method of rendering out DXV with alpha?

I'm assuming that after you switch the output format to AIFF, you then switch back to a format that does support alpha channels, such as Quicktime ProRes It really helped me, thanks mate!

I'm rendering a rather large video file in After Effects, with effects on top of green screened elements, and it seems like I'm runnning into a lot of bugs with the Primatte Keyer plugin. The problem is that the AE renderer while faster than AME is much flakier, and crashes every few hundred frames. Where is this option in Media Encoder? It looks like I get the option to pick " render Alpha Channel only", and "include Alpha Channel", but in both cases I get a solid black background, and not a transparent one. I'm basically pre-rendering a PNG sequence to put back into the larger working file so it's not referencing the actual greenscreened effect and crashing, or glitching the render. Okay, so it DOES give me a transparent background, but doesn't show me with the checkerboard in the preview. Does that also apply to the previews and thumbnails in Finder? I would have thought all PNGs get treated the same once they are exported with a transparent background. The app you use to look at a file with RGB, and A channels determine whether or not you can see or use the transparency. Most apps and all common media players do not support Alpha Channels.

Look at the photos from 1 then 2 then 3. Why does it matter? In Image 1 you have the output format set as Quicktime ProRes

If ProRes files do not play as expected, reach out to the publisher of the application.

If using Adobe Media Encoder, have you chosen a Format that supports including an Alpha and have you chosen a Preset with "with alpha" in the name? In v16 look in next paragraph for v17 it only works when you export "Individual clips" in Deliver page, so if you have more than just a single clip with alpha to be exported, then you gotta first combine these clips into a solid block, such as compound clip select the clips for export, right click, choose New Compound Clip.

Intel is up to 10x, what about AMD? However, if you have some transitions there, it seems that there's no way to render this properly. The checkerboard pattern is the visual language every other Adobe program uses to show a transparent background, but here when I'm exporting a PNG sequence of black shadows it shows that transparent background as solid black.
