How do I use a centre-of-mass and balance check in Cascadeur to make poses and jumps read as physically weighted?

Problem. Poses can look weightless because support and balance are wrong. Conditions. Keyed character animation in Cascadeur, standing or at rest poses and jumps. Method. (1) Use the Center of Mass projection shown on the ground. (2) Pose balance rule from the docs: with one fulcrum point the centre of mass should project on it; with several, the projection should lie between them; otherwise the pose is unbalanced, which is fine in motion but should be fixed for a character at rest. (3) For jumps, mark the last grounded frame and first landing frame, add a ballistic trajectory to the centre of mass, adjust height, distance and time, and snap the centre of mass to it; ballistic ghosts coloured purple show non-physical rotation. (4) Physics priority frames hold chosen poses, but too many reduce accuracy and slow the simulation. Connection to craft. This is the animation principle of weight and balance made checkable (the docs frame it as making motion adhere to physics; the principle names are inference). Failure modes. Over-marking priority frames. Limitations. No Cascadeur session was run; the docs describe the tool at the version online at fetch. Version/date. Fetched 2026-10-23. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Vendor help page; the version it documents is not stated in the fetched text. The Cascadeur help site lists a separate page on AI tools use, not read. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
