After Effect running slow on m1 pro 2021

I have a MacBook Pro M1 Max 64GB RAM + 4TB HD. It went from rendering SUPER FAST to SNAIL SPEED. I tried rendering a simple videohive project and went through a painfully slow 8hr render for a 1.5 minute animation (no plugins). After looking everywhere for answers, somebody shed some light on the problem. A CORRUPT FONT! I replaced the font and re-rendered my project. I went from an 8 hour render to a full render in 3.7 minutes. INSANE! I'm now in the process of curating my font library and getting rid of any corrupt fonts. Hope this helps.

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

I have the same issue on a macbook m1 pro, 16GB Ram, with Ventura and AE 23.2.0 and before. I was exporting a simple project to mp4 via the renderer. The project was a edited 3min Interview as QT ProRes HQ,25fps. I just added a few text layers (names and such). The rendering starts fairly quick, then slows down heavely. After about an hour or so the render was finished. Same project took just 2min export on a pc with less performance. Premiere Pro and other apps runnnig fine and fast. What can we do?

I find After Effects runs very fast and normally for a while, then starts to slow down suddenly. I restart it and it goes back to being fast for a while. It's like the M1 allocates memory away from it and hobbles it... anyone else notice this pattern?

I am having similar issues on my 2014 M1 Pro. I have the 10-core model with 32GB RAM, and the performance is nearly unusable. Using AE v22.6, a 10-second fairly basic timeline that is taking over 2 hours to render (the same project on a colleague's PC takes ~5 minutes). Activity Monitor shows little use, and the battery is hardly draining. Editing text on a soloed layer within the comp has 2-5 second delays. Any acknowledgement or suggestions would be welcome. 

Hi Awais Butt,

Welcome to the community.

Is it the After Effects interface or playback that's slow (could you share a screen recording)? What are the details of the footage you imported (frame rate, frame size, format/codec)? Also, does it happen in all the projects?

Let us know, we're here to help.

Thanks,
