Rotobrush slows down, then stops after trying to render simple short clips in Standard Def AND 1080p

[Letty2019]

I can't take this anymore.

The last few weeks, rotobrush decides not to work.

On 1080p and also 720p....

Just one simple outline of a mans face. Simple stuff. Smooth lines.

Same thing always happens.  It starts doing about 3 frames per second, chugs along fine, then gets slower, then eventually hangs, after about 10 seconds of timeline.

1) I cleared out the media disc caches.

2) I have 32 gb of ram,  gtx1050ti, ryzen 7  a decent set up, especially for Standard Def!!!

It's on cuda, installed the latest driver and still slow!!!

Only thing I've done was make the usual updates. 

I'm losing it.

any ideas????

I selected 2.0 and quality STANDARD  and it reacts the same if I pick BEST.

1.0 is  nightmare, never use it.   I used to use 2.0 and BEST, and it would outline and render in a snap.

Some new Adobe bug out there making people upgrade their GPU's  again?? I don't want to throw money at this problem.  My gpu and ram should work fine for this.

AHHHHHHH!!!!!

Well.... Seeing as the Premiere team is always doing updates (They just got a big update on Premiere). I'm just thinking the work ethic and environment In the After Effects department is different. They have nothing to compete with after effects so it's care free. Premier has to keep up with the competition. After effects has no competition so they could care less we have no where to go. As long as the developers aren't experiencing the technical difficulties we are they won't fix it. As soon as one of the devs can't do side work due to what we are experiencing they will fix it.

I am new to after effects and learning the rotobrushing.  My MacBookPro was having this issue, so I went and bought a brand new MacbookPro 16" with 36 gb ram.  I figured I would be golden.  Nope, still doing this.  I can't figure out how to go to a previous version of AE.

v 18.1  should be in the adobe cloud...    Works great.

Switch to 18.1! This also worked for me! And Im on a Macbook 15" i7 16gb ram, 4gb graphic.

with the latest update it took 24h to propagate a 3sec clip. And now I dont need to worry about it. This is a complete mess from Adobes side. I Don't think this is accaptable...

I am a new student at TAFE and have this issue on a 23 second (60fps) clip, but I don't see any option to download 18.1...even cutting pieces to a couple of seconds, this brush slows to a crawl, and also takes a long time updating after a brush stroke change.

I too was facing the same issue, and trying for hours to get it working. I upgraded from After Effects v18.4 to After Effects v22 (October 2021 release), and the Roto-brush did it work superfast. Quite impressed... finally! :)(:
