Picture lock is the stage in post-production where the video edit is finalized, and no further changes to timing, shots, or structure will be made. From here, audio, VFX, and color grading proceed based on the locked version.
It prevents rework and ensures all teams work from a consistent reference point. Making visual changes after picture lock can break sync and derail finishing steps. It also risks wasted time, misalignment, and budget overruns.
Declare picture lock once all feedback is incorporated and the narrative flows as intended. Any remaining work, audio mix, color correction, subtitles, should be based on this locked timeline.
Review meticulously – Double-check continuity, pacing, and story flow before locking.
Involve stakeholders – Get approvals from directors/producers to prevent late revisions.
Freeze structure – Make sure VFX, color grading, and audio mixing happen only after picture lock to avoid wasted work.
