(See Rotoscoping introduction and resources.) The Roto Brush tool provides an alternative, faster workflow for this segmentation and creation. This has a huge amount of application to lots of other processes and tools inside of after effects, so learning rotoscoping early on in your After. The featured workflow suggests using rotoscoping in Adobe After Effects as an alternative method of masking.

After Effects can then extrapolate from those regions to determine where the boundaries are. Before you draw a stroke along a boundary to attempt to get a precise segmentation, be sure that you've drawn foreground strokes down the center of the object and made at least some rough background strokes on the other side of the boundary.

If you draw a Roto Brush stroke over the wrong area of the image, undo that stroke. Work with resolution set to Full when using the Roto Brush tool. Rotoscoping in after effects this reason, Fast Previews modes are turned off when you rotoscoping in after effects a Roto Brush stroke.

This setting is shared by the Composition and Layer panels.

Rotoscope nature footage

Use the Roto Brush tool in a composition with a frame rate set to match the frame rate of the layer's source footage item. A warning banner appears at the bottom of the frame in the Composition panel if the frame rate of the composition doesn't match the frame rate of the layer's source footage item.

When you've gotten everything as good as you can with rotoscoping in after effects Roto Brush effect, rotoscoping in after effects can touch up the matte further using other compositing features in After Effects—such as by painting on the alpha channel.

See Rotoscoping in after effects and transparency overview and resources. Roto Brush strokes, spans, and base frames Base frames, Roto Brush spans, and corrective strokes When you first draw a Roto Brush stroke, the frame on which you are drawing becomes a base frame. The segmentation information the information about what is defined as foreground and what is defined as background is propagated forward and backward through time—20 frames forward and 20 frames rotoscoping in after effects.

The range of frames thus influenced by this base frame is its Roto Brush span.

Little arrows in the span bar in the Layer panel show the direction in which the information is being propagated. If you draw a corrective stroke anywhere where the arrows point to the right, the information from that stroke is propagated forward; if you draw a corrective stroke anywhere where the arrows point to the left, rotoscoping in after effects from that stroke is propagated backward.

Roto Brush and Refine Matte in After Effects

If you draw a stroke anywhere outside of a Roto Brush span, then you create a new base frame rotoscoping in after effects span. You can work your way forward a frame at a time from a base frame, making corrective strokes, and you don't have to worry about your strokes changing results on frames that you've already worked on.

You can do the same thing going backward from a base frame. The influence of each corrective stroke propagates forward or rotoscoping in after effects to affect all frames in that direction within the span, regardless of when the stroke is made.

For example, if the base frame is at frame 10, you make a corrective stroke at frame 20, and then you make a corrective stroke at frame 15, then frame 20 will be affected by both of these corrective strokes—just as if rotoscoping in after effects had made the corrective strokes in the other order.

rotoscoping in after effects Each time that you make a stroke within a span, the span grows, unless it can't because the span in which you're drawing is adjacent to another span.

To manually change a span duration, drag either end of a span. To delete all spans, delete the instance of the Roto Brush effect. When you move rotoscoping in after effects a frame within a span, After Effects must calculate how the stroke information from the other frames in the span affects the frame to which you've moved.

This information is cached, so this propagation doesn't need to happen every time that you move to a frame.

Green bars in a span indicate frames with cached information. Roto Brush tool, Roto Brush strokes, and similarities to paint tools and strokes The Roto Brush tool is similar in many ways to the paint tools, though it also has several important differences. When the Roto Brush tool is selected, controls in the Paint panel are disabled.

Roto Brush strokes have a duration of one frame, though their influence propagates forward rotoscoping in after effects backward within a span.

You rotoscoping in after effects change the brush size Diameter for the Roto Brush tool in the same way that you change it for the paint tools.

Other controls in the Brushes panel do affect the Roto Brush tool, with the exception of Hardness. You can copy Roto Brush Path properties, and paste them into masks, shapes, and instances of the Paint effect, just like you can with other kinds of paths.
