Check a final master

What this is about

By the time a film is finished, everyone involved has seen it so often that nobody sees it any more. The brain fills in the missing frame, reads the correct spelling over the typo, and hears the sentence it expects. That is why the final check needs a different mode of attention: not watching the film, but inspecting it, in a fixed order, ideally by someone who did not build it. Ten focused minutes at this point prevent the specific class of error that is cheap to fix beforehand and expensive to explain afterwards.

The order matters more than the tools. Skip a step and you usually notice two steps later — by which point the fix costs several times as much.

What runs differently here

In planning terms, that means:

• Have someone check who did not edit the film; the person who built it can no longer see it
• Check the very first and very last frames separately — stray black, a frozen frame or a cut-off word live there
• Verify the logo version, the claim and the legal line against the client's current brand assets, not last year's
• Names and job titles get checked against a written source, never against memory
• Watch once at full length in one sitting: scrubbing hides the errors that only show in playback

Step by step

This order gets you there fastest:

1. Watch the master once from first to last frame without stopping, on a decent screen with decent sound. Note timecodes only; investigate nothing yet, or the pass turns into an edit session.
2. Check picture integrity: no stray black frames, no unrendered sections, no leftover placeholder, no frozen frame at the end and no visible glitch at a transition.
3. Check sync across the whole film, especially after graphics and at the ends of long takes. Drift usually appears late in the timeline, which is exactly where attention has faded.
4. Read every word on screen out loud, including lower thirds, end cards, URLs and legal lines. Reading aloud catches errors that silent reading repairs automatically.
5. Verify brand elements against the client's current assets: correct logo variant, correct colours, correct claim, and the right legal entity in the imprint.
6. Confirm audio: loudness measured against the agreed target, dialogue intelligible on a phone speaker, no clipping, and both channels carrying what they should.
7. Check subtitles and safe areas on the actual target format — text inside the safe area, no overlap with graphics, and correct language for the version you are shipping.
8. Log the result with version number, date and checker name, then release. An approval without those three fields cannot be relied on when a question comes back weeks later.

Common pitfalls

What most often goes wrong in practice:

• Letting the editor be the only person who checks their own master
• Scrubbing through the timeline instead of watching the exported file in real time
• Checking the master but publishing a different export that was never checked
• Approving by email without naming which version was approved

With TillyGen

The deliverables agreed in TillyGen give the final check a definitive list to work against — formats, lengths and languages that were promised, rather than the subset that happens to be sitting in the export folder.

Change one constraint and the consequences travel through the whole plan: affected shots are flagged, the call sheet is regenerated, and nobody keeps working from yesterday's version.
