Make Render & Replace (with alpha) work for common SoMe frame sizes
The Render & Replace feature in Premiere Pro is great, especially for complex MOGRTs that will not play smoothly. It's much better than rendering the sequence, since we can still move the clip around without re-rendering. It's fantastic!
But the only option for MOGRTs that are not full screen (and most are not) and need an Alpha channel is GoPro Cineform. That's a very good codec, but it has some limitations that makes it unsuitable for non-broadcast frame sizes: The frame width must be evenly divisible by 16 and the frame height by 8. Adobe knows this: https://helpx.adobe.com/premiere-pro/using/gopro-cineform-codec.html#TipstoworkwiththeGoProCineFormcodecbr
This means that Render & Replace will fail in a 1080x1080 or 1080x1920 sequence for social media.
1080/16 = 67,5 – which is not an integer. The same is true for sequences that are 1350x1080. 1350/16 = 84,375 – which is not an integer.
These sizes are widely used in videos for Social Media! And we can't use Render & Replace (with alpha) when editing videos for them.
We can't have this nonsense anymore!
We need ProRes 4444 with alpha in addition to Cineform with alpha for Render & Replace. ProRes is much more flexible. Oh – and we need to be able to choose the default format. Or at least it should be sticky, so we don't have to change it every time.
Quicktime ProRes 4444 was added as a codec for Render and Replace in the Premiere Pro July 2020 release (14.3.1)
Thank you for taking the time to submit this, Jarle. The way I read this, it is a request for a new built-in Render and Replace / Quicktime preset in Pr, and not necessarily specific to Graphics, correct? If so, I will try to get this routed to the right group internally. Did you also submit a request for this on the Beta site? It's fine if not. I just need to identify one work item for internal use.

@Sven Brencher: yes we can make our own presets, but I can't tell all my MOGRT customers to do this. It should work as expected straight out of the box. I would rather have one programmer at Adobe spend 10 minutes fixing this, than have lots of people fiddle around with export presets settings and maybe fail. :) There's no good reason to NOT have this option.

But you can create your own ProRes 4444/Alpha export preset in AME and then import it into the Render and Replace Dialog.

+1 for this request. R&R should function fully at all resolutions.
