after effects crash dynamic link roto brush

Suggestions for using Rotobrush:

1. Pre-compose the layer, trimming the length to the duration of the layer and moving all attributes before you try to use Rotobrush.
2. Use Dynamic Link to create the composition, save the AEP file, then return to Premiere Pro and undo the Dynamic Link you just used to create the AE Composition, then follow Step 1.
3. When Rotobrush is complete, select the layer in the timeline, Pre-compose again, move all attributes, then use the Composition/Pre-Render menu to render a high quality with alpha copy of your video so you don't have to rely on AE to handle Rotobrush and any other effects or layers you may add (I do this any time Rotobrush takes longer than about 5 minutes to complete).
4. When you finish the composite, render the final comp, then import the file to Premiere Pro and drag it on top of the original clip. You can then delete the original or move it to a nonrendering layer.

Following those recommendations will give you the best chance of a flawless workflow, and the final sequence will render in much less time, with the possibility of failure greatly reduced.

Hi Corbin,

I can't see the error. Do you mind trying that again or sharing screenshots? Could you also let us know the version of After Effects you're using?

We're here to help. Moving this thread from Bugs to Discussions for now.
