Using new keyframe-looping methods


    After Effects 5.5 includes four new keyframe-looping methods usable on any property except marker. They are as follows:

    loop_in(type = "cycle", num_keyframes = 0)

    Loops a segment of time that is measured from the first keyframe on the layer forward toward the layer's Out point. The loop occurs from the layer's In point to the first keyframe on the layer. The segment to loop is delineated by the specified number of keyframes.

    loop_out(type = "cycle", num_keyframes = 0)

    Loops a segment of time that is measured from the last keyframe on the layer back toward the layer's In point. The loop occurs from the last keyframe on the layer to the layer's Out point. The segment to loop is delineated by the specified number of keyframes.

    loop_in_duration(type = "cycle", duration = 0)

    Loops a segment of time that is measured from the first keyframe on the layer forward toward the layer's Out point. The loop occurs from the layer's In point to the first keyframe on the layer. The segment to loop is delineated by a user-specified duration.

    loop_out_duration(type = "cycle", duration = 0)

    Loops a segment of time that is measured from the last keyframe on the layer back toward the layer's In point. The loop occurs from the last keyframe on the layer to the layer's Out point. The segment to loop is delineated by a user-specified duration.
