许可您删除内乱置受版跟踪器天生的“没必要要的”枢纽帧。它将检察受版的跟踪器天生的每帧枢纽帧，并删除降进取其前任类似的阈值以下的那些帧。
施行两遍：移除战减固。
删除历程包罗删除取上一个枢纽帧过于类似的枢纽帧。当两个极点的挪动均已超越指定的（移除）阈值时，两个枢纽帧被视为类似。
强化历程会阐发其他枢纽帧的每一个持续对。当极点挪动超越（加强）阈值时，将正在两个枢纽帧的中心从头引进先前删除的枢纽帧。反复该阶段，曲到每对皆满意前提为行。枢纽帧削减的百分比将写进疑息里板。
Allows you to remove ‘unnecessary’ keyframes generated by the built-in mask tracker. It will look at the mask’s tracker-generated every-frame keyframes and remove those frames that fall under a threshold of being similar to their predecessor.
Two passes are executed: removal and reinforcement.
The removal pass consists of removing keyframes that are too similar to the previous one. Two keyframes are considered similar when none of the vertices has moved more than the specified (removal) threshold.
The reinforcement pass analyzes every successive pair of the remaining keyframes. When a vertex has moved more than the (reinforcement) threshold, a previously removed keyframe is reintroduced in the middle of the two keyframes. This phase is repeated until every pair satisfies the condition. The percentage of keyframe reduction is written to the Info palette.
