What matters in practice
On most projects, less than half the work is done when the last shooting day ends. Post-production is the umbrella term for everything that follows. It is the reason weeks can pass between the shoot and the finished film even though the footage is, as clients often put it, already in the can.
What it covers
- Reviewing and backing up the footage: copies on separate drives, sorting, a transcript where there are interviews. Invisible in the result, and the basis for everything after it.
- Editing: selection, order, length.
- Sound: intelligibility, unwanted noise, music, consistent loudness across every version. The stage whose absence viewers notice fastest and can name least.
- Colour grading: the look of the film.
- Motion design: lower thirds, logo, explanatory graphics.
- Delivery: final versions in every agreed format.
Concept, script and shoot are not part of it. So a single line reading “post-production” in a quote covers six distinct crafts.
Why the order is fixed
These stages do not run in parallel. Sound, colour and graphics are built on a picture version that no longer moves, and they only start once it has been signed off. One shot shifted afterwards pulls all three back through the process. That makes sign-off of the picture edit the most important date in a project, not the final approval at the end.
What to settle in advance
Two things: how many rounds of revisions are included, and who signs off. Comments arriving one by one from five departments over a fortnight, some of them contradicting each other, are the most common cause of missed deadlines. Collected feedback with a timecode routinely saves a whole round. Say “wrong company name at 1:12” rather than “that bit in the middle”.
