# Consistent exercise demonstrations

All 33 clips and their reference frames use 640 × 360 (16:9). Five movements use newly sourced footage; the other 28 retain the original supplied animation with proportional fitting and white padding. Padding preserves the whole source frame and its watermarks. Left/right source clips are retained without mirroring. There is no change to exercise identities or workout targets.

The appearance of U.S. Department of War (DoW) visual information does not imply or constitute DoW endorsement.
