Render and Replace not importing roto brush masking

[SundayGladiator]

Morning!

So I've gone coo coo with Pr and using AE compositions with rotoscoping (roto brush masks..) as dynamic links. Yay!

However going back into Pr and scrubbing through the timeline is about as painful as watching paint dry. The frame rate is long enough for me to get out of my seat and make more coffee and come back, and it's half done watching the frame rates resolve.

So I'm reading here to take those AE clips and change them to 'Render and Replace' so it's embedding in Pr and no more DLs. But the issue is it does not bring in my roto brush mask.

Any tricks or settings I need to be aware of?

Export from AE with intermediate codec and put that on the timeline.

I could use more specifics. What are the steps to do that in AE?

Google is my friend...

However need some education - what is an intermediate codec? eg - H.264?

Can you tell me what my export settings should be from Media Encoder to export the .mp4 with the roto brush mask?

Not even close.

Prores or Cineform.

Open the output module

Set it to QuickTime

RGB + alpha

Format options: Prores 4444

Bingo Brilliant. Thank you! 🙏👊👍

Performance now in Pr is remarkably improved without DLs. I mean what kind of Mac and horsepower would it take to see those DLs in real time?!

Not my dinkmo Macbook!

I will go the QT ProRes 4444 here on out. So far it the AE clips appear to pick up those roto brush masks flawlessly.
