Edit is final and approved — no further changes to cuts, transitions, or sequence order. Sound design, color, and VFX lock to this version; revisions = budget bleed.
The edit is complete — and from this point on, it will not be touched. Locked Picture means the sequence of shots is in its final form. No more frame trims, no subsequent cuts between shots, no new transitions. The editor gives the green light, the director approves, and then the material moves to the next phase: sound, color grading, visual effects — all departments build upon this fixed picture version.
In practice, this moment is a milestone, but also a test of nerves. Because Locked Picture signifies commitment. The sound designer synchronizes music and effects precisely to the edit points — if a cut shifts by two frames later, the explosion will no longer land correctly. The final DCP format is provided to the color grading suite, and edit lists are distributed to all departments. Any subsequent changes to the picture sequence incur additional costs because all dependent processes must be recalculated and sometimes repeated. For blockbusters with hundreds of VFX shots, returning to an open edit is often no longer economically viable.
Therefore, intensive discussions take place before this point. The rough cut, the first assembly — these phases are for experimentation. One reviews with the director and producer what works, where a scene breathes or where it is stifled. Pacing issues, transition flaws, timing errors — everything is still addressed. But as soon as Locked Picture is declared, it means: the decision is made. Period.
Practically on set: The editor clearly communicates this status to all departments. The edit lists are marked as the final version — often with a version number and freeze date. For longer productions, there may be multiple locked cuts in succession (teaser version, theatrical version, TV version), but each one is then an autonomous, self-contained entity. Anyone who wants to push through changes after the lock needs either a very good reason or — and this happens — accepts that certain downstream work will have to be redone. That is expensive. Therefore, the Locked Picture decision is final.
