Hello, I have a dynamic link from premier pro.

Everytime I load it to do more of roto brush things it just keeps propagating (big word). it wont stop. it keeps going and going and going and going all day. it wont let me do any more things it says 

After Effects warning roto brush strokes cannot be added until the current frame has finish rendering ok

I need to go to finish my home work and this is bad.

Installed RAM 16.0 GB
System type 64-bit operating system, x64-based processor

You may be trying to rotobrush the entire clip instead of the trimmed clip in the comp that Premiere Pro created. Without workflow details and screenshots we have no idea what is going on. This is not a bug in any of the releases of After Effects that I know of. There are others, but not finding the end of a clip isn't one of them.

hello Rick,

how do I send workflow details? is that showing my dynamic link stuff? sorry I am not quite sure how to send that.

Taking screenshots with the modified properties of the problem layers revealed are the easiest way. Reveal them by selecting the layers and pressing the 'u' key twice. Windows and Mac both have very quick keyboard shortcuts for taking a screenshot of the entire screen. Then you can simply browse to the image, copy it, and paste it to the reply field on the forum or use the toolbar, or drag it into the reply field. A screenshot of the Layer Panel showing Rotobrush and the Effects Control Panel will also help.

* The "Drag & Drop here..." area is buggy and should not be used to share images. Please use the toolbar or just drag your images to the reply field.

Hello Rick, working on it. trying to select the line is hard and I keep pressing u u. When we do a dynamic link, instead of taking the small clip over it takes the whole film bit. we thought it was normal.sometimes it is hard to find which part of the clip we are doing or when to stop with the effect. crazy right? getting your pictures now

thank you
