A moving garment extends beyond the underlying limb. If a mask follows only the apparent arm or skeleton, a wide sleeve can be clipped as it opens. Review the garment’s complete changing silhouette, including folds and motion blur, across the dance interval. Keep the character pass intact while refining its isolation; do not reshape the costume merely to fit an overly narrow mask.
Find the widest garment pose
Locate frames where sleeves, skirt or coat tails extend farthest from the body. These are better mask tests than the resting first frame. Also inspect moments where fabric overlaps the torso or another performer, since a valid outer contour does not solve every internal occlusion.
Compare the generated clothing with the approved identity image. If the garment changes design before masking, that is a separate identity or material failure. If it is intact in the pass but truncated in the composite, the isolation stage is responsible.
Audit cloth and anatomy separately
- Preserve the complete generated character pass.
- Mark maximum garment extension and limb positions in the test interval.
- Review the matte against both, including blurred cloth boundaries.
- Correct propagation when the fabric separates from or overlaps the arm.
- Render the interval and check the costume silhouette at normal speed.
Adobe’s rotoscoping workflow provides external isolation tools. A brush or automated propagation does not understand the project’s costume-continuity requirements without review. Keep enough source detail to distinguish cloth from the receiving background.
Reject clipping disguised as cleanup
A hard edge at the elbow or sleeve hem may be mistaken for clean compositing. Compare it with the source pass: fabric should not suddenly acquire a straight cut when the dancer raises an arm. Examine the return motion too, where a newly corrected edge may collapse back into a narrow mask.
Should I select tighter clothing for every replacement?
It can simplify some shots, but changes the creative brief. Make that choice intentionally rather than describing a cropped sleeve as successful reproduction. If the approved costume is essential, the workflow must accommodate its motion volume.
Can a motion skeleton determine the sleeve outline?
No. Joint positions describe body structure, not all cloth movement. Use visible garment evidence and a reviewed matte, while treating any generated cloth behavior as an interpretation rather than captured fabric physics.
