X-Spline Roto: Draw an X-Spline roto mask. The number of these 'outliers' can be adjusted using the Identify pixels that are not part of the object and ignore them during To improve tracking accuracy when the mask becomes occluded by another

This allows the tracking to adapt to small changes in the imageĬontent, but also means that the mask may drift during tracking. Is enabled which means the tracking template will be updated in eachįrame. the image pixelsĬontained inside the mask) are matched from frame-to-frame, and the When tracking starts, the tracking template (i.e. Need to adjust a vertex position in every frame. This means a mask canīe tracked and then its vertices keyframed independently, without the Of that produced by keyframing vertex positions. Note that the mask transformation obtained by tracking is independent Masks can also be tracked from frame-to-frame. Tracking MasksĪs well as hand-animating a mask throughout a clip, Roto and X-Spline Move to the previous or next frame that contains a keyframed vertex. The K- and K+ buttons can be used to quickly Window will display a context menu allowing the vertex to be changedįrames where a mask has been keyframed are displayed with yellow Masks can be translated, scaled or rotated as a whole, as well as individual vertices be moved.įor Bezier roto splines, right-clicking on a roto vertex in the Cinema To animate a mask as a whole, select it from the mask list and pressĪnd hold the Control key to display the transformation Not intersecting the parent will be masked.

The way that child masksĪffect the overall shape of the parent can be modified using Boolean Boolean OperationsĪfter a top-level mask is created, creating additional masks will add In the mask list and then clicking and dragging one of its vertices Once created, a vertex group can be moved as a whole by selecting it Vertices can be grouped together and moved as a single entity if Outer and inner boundaries for all vertices at the same time. The Roto Thickness edit box can be used to set the distance between This can be used to adjust theĭistance between the outer and inner boundaries.

This allows the inner or outerĮdges to be adjusted independently of each other, producing a softįor X-Spline masks, the position of the inner boundary is controlledīy a white handle at each vertex. When only one button is pushed, only theĬorresponding spline will be adjusted. When both buttons are pushed, both the inner and outer splines will beĪdjusted at the same time. To control which of the inner or outer splines are adjusted. Mask vertices, the Edit Inner and Edit Outer buttons can be used Masks, both the inner and outer splines are identical. Represented by an inner and outer boundary spline. Inner and Outer Splinesīoth Bezier and X-Spline masks can have either soft or hard edges, Masks can be moved in the list using drag-and-drop to change their parenting. The top-level mask using a Boolean operation. Each child mask can be animated independently and combined with Painted using using the Colour X-Spline and converted into an X-SplineĮach Roto node can contain several top-level mask, each of which can have several child The image below shows an example where the actor's outline has been Similar to the outer edge are assumed to be part of the background. Inner and outer roto edges: Pixels that are more similar to the innerĮdge are assumed to be part of the object, and pixels that are more X-Splines are used for the X-Spline Roto and ColourĬolour X-Spline masks are similar to X-Spline Roto masks, but theĪctual mask boundary is defined by the colour differences between the The Roto node supports two different types of splines: Bezier splinesĪre used for the Bezier Roto, Rectangle, Ellipse and Lasso Masks files can also be imported from third-party applications such as Multiple indicators if required, with the same mask activated on each Roto node, it can be attached to any other node that has a purpleĬonnecting a mask node in such a manner will activate the mask on theĬlip to which it has been attached. With operations such as automatic feature tracking. The Roto node can be used to generate a spline-based mask to assist
