When a replacement begins sliding after only the background is stabilized, compare the layers' coordinate spaces before changing the character motion. Stabilization can move, rotate or scale the base differently on each frame. A replacement aligned to the untreated base will not automatically follow those new coordinates.
Find the first version that drifts
Keep the untreated composite and the stabilized export available. Follow a fixed floor mark and the replacement's contact point through both. If their relationship was stable before treatment and changes afterward, the new transform is a plausible cause. If the character already slid in the untreated version, repair that earlier problem separately.
Adobe's tracking and stabilization documentation distinguishes movement tracking from stabilization. The useful production principle is to apply a consistent spatial relationship to the layers that must remain registered. It is not evidence that any one stabilization method solves a generated performance.
Choose one coherent processing order
One option is to stabilize a reviewed common base first, then track and composite all replacements in that stabilized space. Another is to finish the aligned composite in the original space, then stabilize the assembled image. An advanced workflow may share an identical transform across relevant layers, but verify that the actual editor applies matching timing and coordinates.
Avoid separately stabilizing each generated character. Each calculation can choose a different subject, crop and movement. Matching their opening frames will not prove they stay aligned later. Preserve the original project so an unsuccessful order can be reversed without repeatedly processing a compressed export.
A hypothetical stage replacement
Suppose a replacement performer follows a floor marker correctly in the raw composite. The editor then stabilizes only the filmed stage. During a handheld bump, the floor shifts beneath the replacement while the performer stays in the old screen position.
Compare a short interval around that bump using the untreated composite and a version where the assembled frame receives one reviewed correction. Check the marker, feet and important foreground overlap. This is a proposed diagnostic comparison, not a measured stabilization result.
Review crop and geometry as separate conditions
A shared transform can solve registration while still cropping a hand or bending a face. Check the widest gesture and every important contact after the final framing is chosen. If stabilization changes action timing or essential geometry, reduce the correction, retain some original shake or select another shot.
Accept only when layer relationships remain stable throughout the usable interval and the action survives the crop. Reject a version that hides sliding by trimming away the feet without an approved framing change. Save the processing order and transform source with the project. These procedures belong to external compositing and editing; they do not imply that Imagild provides synchronized stabilization for generated layers.
