Clip Loop Fit

Overview

Automatically adjusts a clip so it joins seamlessly in a loop. It copies the initial state to the end to eliminate the jump from the last frame to the first. Place it near the end of a repeating motion such as a walk or idle animation.

Usage tips

• Place it immediately after the clip: keyframe_clip → clip_loop_fit → clip_apply_*. Even if you did not account for looping while recording, you can close the clip afterward with this node.
• If the recorded final pose differs greatly from the initial pose, this effectively adds a "return" motion at the end. If the return is too abrupt, adjust the end of the recording closer to the initial pose.

Related nodes

• keyframe_clip — the clip to adjust
• clip_mixer — you can also fit the loop after mixing
• clip_apply_path / clip_apply_image — apply the adjusted clip

Technical details

Internally, the node uses loop_fit on RecordedLayer to add each track's initial state at the end of the duration. It is a helper for making short loops join cleanly at the clip stage.

Examples

• Pass the output of KeyframeClip through ClipLoopFit, then send it to ClipApplyPath / ClipApplyImage.

Closure, not periodic wrapping

Clip Loop Fit adds the first sample at the duration endpoint so the endpoints match. It does not wrap evaluation times outside the duration. Use a looping progress source when periodic playback is required. progress is normalized 0–1 and evaluates progress × duration (frames). Exporters (keyframe_clip spritesheets and animation_render) sample frames t=0..D-1 of a D-frame duration, so the last frame of a loop-fitted clip stops just before returning to the start (loop rule D7).
