This might be more ideal for footage which requires more correction strokes. You can also use Cmd/Ctrl + Left/Right arrows to propagate frame-by-frame either forward or backward, if you would like to go slower and evaluate the propagation more closely. This will trigger the propagation of the matte from the base frame to the new frame. Once you are happy with the selection on the base frame, press the Spacebar to start propagating the selection through the footage. Refine the selection by painting additional foreground strokes, or paint background strokes by holding Alt/Option to remove portions of the selection.īackground stroke, removing from selection: This creates a base frame ( visible as a blue highlight in the Time Ruler of the Layer panel. Avoid painting across edges as this might confuse the selection.
Paint a green foreground stroke on the subject, object, or region you are attempting to roto. This will open up the layer in the Layer panel.
Select the Roto Brush Tool in the toolbar ( Alt/Option + W ).ĭouble-click on an existing layer in the Composition panel. The application of Roto Brush with the new propagation engine is largely the same as in previous After Effects versions: zip to your Creative Cloud storage ( or Dropbox, OneDrive, etc ) and email a link with a brief description of what you were experiencing to All footage submitted will be kept confidential and will not be shared with third-parties.
- Zip up the folder containing the newly-collected project and footage.
- Click "Collect" and select a location to collect the project file and footage.
- Set "Collect Source Files" to "For Selected Comps".
-
Go to File > Dependencies > Collect Files.In the Project panel, select the composition that contains the footage with Roto Brush applied.If you are willing and able to share footage with the After Effects team where Roto Brush 2 is having difficulty isolating a subject when propagating, please follow these steps to submit the footage and project: Your testing efforts and input are highly appreciated. We are looking primarily for feedback on how the new propagation engine is performing with real-world footage, though all feedback is welcome.
