Seedance 2.5 Extend: Continuity Guide

How to work through it

Choose the extension boundary

Select a source frame where motion, occlusion, focus, lighting, and subject geometry are readable enough to continue. Record the exact source asset, version, timecode, preceding action, camera vector, focal behavior, and scene state at that boundary. Avoid cutting at a moment when hands cross the face, a prop disappears behind the body, or fast motion hides the intended direction unless the test is specifically designed for that difficulty. The boundary record is the anchor for evaluation even if the authorized tool ultimately uses different inputs or exposes no dedicated extension control.

Protect continuity before generating

List what must remain stable: subject identity, wardrobe, prop ownership, spatial layout, light direction, weather, background traffic, lens character, camera path, action trajectory, and narrative beat. Then list what may evolve during the added duration. Use reference stills only when their rights and purpose are documented. Define a maximum extension length for the test and a fallback cutaway that can hide a failed join. This separation prevents a reviewer from rewarding a visually appealing continuation that breaks the story or silently changes a protected element.

Review the join and the new ending

Inspect several frames before and after the join, then watch the full shot at delivery speed. Check identity, geometry, texture, motion phase, camera velocity, exposure, background persistence, and audio continuity where relevant. Evaluate the new terminal frame separately because a plausible join can still create an unusable ending for the next edit. Log pass, repair, regenerate, trim, or replace, with timecoded evidence. Confirm current official controls and account access at execution time; social circulation and this guide do not establish availability, duration limits, quality, or repeatability.
