Running slow with Mac Book Pro M1 Pro

Hi, I hope this helps, I was trying to rotoscope clips in premiere pre using the dynamic link, having big problems, I was getting warnings about the framerate,  I tried multiple methods that I found on youtube, and it still super laggy and i was left with a poorly rendered clip... Until i used this method! I first of all created a proxy for all my clips in premiere pro, then created a duplicate of the clip that i wanted to to rotoscope, then I turned off all the effects of the clip apart from motion i then nested the clip and proceeded to click replace clip with aftereffects composition... in after effects i chose the composition in the project window and created another proxy in after effects, then precomposed the clip, and after that rotoscoping worked seamlessly like in seconds it was done and i the chose to freeze it and went back to premiere pro and the clip was rotoscoped and working seamlessly... I'm on a 16gb M1 btw! I made a video and posted it on youtube hopefully this will help a lot of people from jumping through hoops or looking to upgrade their computer! https://youtu.be/izOS89KW4xI

The current AE version is not Apple Silicon native. You can try the beta version that is currently available for Creative Cloud subscribers. Open your Creative CLoud desktop app, on the left side you have a column where you can find the available beta apps.

Also you can try to deactivate GPU acceleration on File > Project Settings, under the Video Rendering and Effects tab. Try to reduce the RAM amount assigned to AE in AE Preferences under the "Memory" category. 

Anyway, I'm running the current AE version on a M1 Pro Macbook Pro without any big issues.
