I don't have as stark an issue as this, but does resolve around GPU acceleration, rendering, and the m1 max macbook.
My experience is such:
My video is vanilla mp4, I have a dynamic link AE comp for a lower thirds.
in timeline when just playing unrendered (bar is yellow or red) it plays at lower quality, sometimes less than native framerate. No harm, no foul: understandable.
in timeline after rendering a preview (bar is green) it looks and plays 100% - see attached DynAE high quality.png
Now, here is the issue: short of rendering every dynamic link AE comp and then swapping it into the timeline, I cannot get the final output to look like that high quality render. I can't find the correct output format to achieve this. It instead looks like the attached bad quality.png (that I cannot add seeing as I forgot to add it on the first go-round. Just know it looks tellingly lower quality on the lower thirds than either of the attached).
Another oddity: I have a dynamic link WITHOUT any video in the background, and it outputs correctly.
I attempted to use previews in my render, with and without CPU acceleration. When I did not use CPU acceleration
I put forth these issues:
1. What you see MAY OR MAY NOT BE what you get. It's a total gamble. The settings within Premiere may or may not make a difference when it comes to achieving a good quality. OR that you have to do it all manually, reducing much of the time-saving capabilities of much of Adobe's ecosystem. It's just all so unreliable, or the reliably is so unknown.
2. There is a glitch. I attempted to the work-around of rendering the timeline (asterisk, only the RED bars) and then output using the render preview settings AND using only CPU. The video that was good was 100%. But at random/unable to ascertain reasoning times - in the middle of previews that WERE certainly rendered, and other times that perhaps weren't - I would get a BIG BLACK NEEDS GPU warning band across the video. Again THIS DURING TIMES I KNOW HAD TO BE RENDERED.

I hope there's a bigger resolution to my issue(s) that can be resolved with a better understanding and iteration due to the new mac max one chip, or something that large, but is a general development concern.

Currently, these issues provide me a poor user experience that gives me little faith in expecting good results from Adobe's tools. And I know my use case is small, with minimal footage and graphics, yet I have these issues. I can only imagine what others might have to contend with if they're deciding to use Adobe.

Hi Bernice,

Those are definitely some big differences in render outputs. 😳

Can you tell me more about the graphics you’re using?
We’re they made natively in PR or are they from AE Mogrts?
Are you exporting directly out of PR or queuing to AME?

Would you mind installing the latest Beta version of Premiere Pro? It’s available from the Creative Cloud Desktop App and is a standalone app so it won’t un-install the release version of PR. There was a fix to Media Core that may resolve this for you.

Lastly, would you be able to share the files that you’re seeing this issue with so that we can try and repro in-house?

Thanks,
Dacia
