After Effects Roto Brush Propagating
on Nov 16, 2010 at 12:39:45 am

I am attempting to use roto brush on several clips approximately 3 mins in length. After about 15 seconds worth of propagating AE erases the data, leaving me to have to start all over again. I am wondering if this is just a RAM issue, or some setting that I change to have the system perform better. I currently am using 4GB of RAM.
Thanks for your help
Paul

I haven't attempted such a long Rotobrush yet, so I can't answer your question from direct experience.

But I can say that for AE 10, 4GB is woefully inadequate, and I could very well contribute to your problem. You really do need to get more memory for your machine, and the sooner you do it, the better. Think 16 GB for starters, and more if you can afford it.

As far as my experience with Rotobrush goes I do not think AE erases the data, I worked on 10-15sec clips with no problems- like Dave said it may just be a RAM issue.

Here are some potentially useful resources on the Roto Brush.

Like Dave, I too haven't had much time with Rotobrush. But it looks like an awesome helper tool. It can be a resource hog so you will want to splice your clip into 30 second segments.

Good Luck

To Paul, I experience the same problem. I roto brush 3 minutes of a music video. I'm working on a macbook pro with 4GB of ram. I upgraded to 8GB and it only improved slightly. So I decided to focus on roto brushing a few seconds at a time and that works great. So I would agree with everyone, the more ram the better (16GB+) might be the way to go.
