How post-production works, from ingest to final delivery

What are the stages of post-production, in order?

Post-production is everything that happens to a film between the last shot and the file you publish. For a brand or corporate film it runs in a fixed order, and each stage hands the next a decision that should not be reopened. This is the sequence we work to, with what you see as the client at each step.

1. Ingest and backup: footage and sound are copied, verified and organised. You see nothing yet, but everything depends on it.
2. Assembly: the usable material laid out in story order. Usually internal, sometimes shared on long interview-led films.
3. Rough cut: the story in its intended order and close to its final length. Your first review.
4. Fine cut: timing, pacing and shot choice refined until the picture can be locked. Your second review.
5. Graphics, colour and sound: titles, motion graphics, the grade and the mix, applied to the locked picture. Your final review.
6. Delivery: the master and every agreed version, named and checked.

The principle behind the order is simple: decide the expensive things once. Story is cheap to change in a rough cut and costly to change after the grade and mix, because every later stage is built on the exact frames of the edit. Our video production process follows that rule, with colour, sound and graphics finished only after the picture is locked.

What happens at ingest and backup?

Ingest is the moment footage moves from camera cards and sound recorders onto storage the edit can use. It is the least visible stage and the one where a mistake cannot be undone, because a card cleared before it was safely copied is footage lost for good.

What a careful ingest includes

• Copying every card in full, not selected clips, so the folder structure and metadata stay intact.
• Verifying each copy against the source with checksums, rather than trusting that a copy finished because the progress bar did.
• Keeping at least two copies on separate drives, one stored away from the edit suite, before any card is cleared.
• Organising by shoot day, camera and card, with one naming convention used across the whole project.
• Logging the settings that affect the edit: frame rate, resolution, and whether footage was shot in a log profile that needs converting before it looks normal.
• Syncing separately recorded sound to picture, by timecode where it was recorded and by audio waveform where it was not.
• Creating lightweight proxy files when the originals are too heavy to edit smoothly, while keeping the link back to the full-quality files for the finish.

What goes wrong here

Mixed frame rates are the classic surprise: one camera at one rate, a drone or phone clip at another, discovered only when the footage judders in the timeline. Missing sound is the other. When the shoot crew and the edit team are different people, ask for camera reports and sound logs with the hand-over drive; it costs the crew minutes and saves the editor hours. Good coverage on set, the subject of our guide to cinematography basics, only helps the edit if it arrives intact and labelled.

What you see as the client

Usually nothing, and that is as it should be. What you can ask for is confirmation that the footage is backed up in two places, and how long the studio keeps it after delivery. That matters if you will want new edits from the same shoot months later.

What is an assembly, and how does it become a rough cut?

An assembly is all the usable material laid out in roughly the order of the script or plan. It is long, loose and unpolished on purpose: the editor's job at this point is to see everything that exists before deciding what the film is.

Building the assembly

For a scripted film, the editor lays the best takes of each scene in script order. For an interview-led film, such as a founder film or a documentary, transcripts come first. The editor, often with the producer, reads every answer, marks the lines that carry the story and builds a paper edit: a document listing the chosen sound bites in order. The assembly follows the paper edit, so even the first watchable version has a shape.

Some films are shaped mainly by selection. For the official one-year celebration film for Kantara: A Legend from Hombale Films, where we contributed editing, motion graphics and post-production, the work involved curating key moments from the film's journey, audience reactions, cultural milestones, achievements and critical recognition. When a film is built that way, choosing what goes in is the story, so the assembly carries more of the creative weight than usual.

From assembly to rough cut

The rough cut is the assembly cut down to the story the film is meant to tell, in its intended order and near its target length. It has rough edges deliberately:

• Temporary music, chosen for mood and pace, which may well change.
• Placeholder cards where graphics will go, each saying what it will show.
• Ungraded picture and an unmixed soundtrack, so colour and levels jump between shots.
• Marked gaps where a pickup shot, a screen recording or a product shot is still to come.

What you see as the client

The rough cut is your first real review and the most important one. Judge it on story alone. Does it say the right thing, in the right order, to the right audience? Is anything factually wrong, including what speakers say about your business? Is anything missing that must be there? Notes on colour or music at this stage are easy to give and rarely useful, because both will change. Notes on structure are the ones that save money, since this is the cheapest point to act on them.

What changes between the rough cut and the fine cut?

The fine cut keeps the story agreed at the rough cut and works on everything that makes it play well: timing, rhythm, shot choice and clarity. Where the rough cut asks whether this is the right film, the fine cut asks whether every second earns its place.

The work in a fine cut

• Trimming each shot and sound bite to the frame, removing pauses, repeats and false starts.
• Choosing the strongest take of every moment, which may differ from the rough cut's choice now the order is settled.
• Laying cutaways over interviews so viewers see what the speaker describes.
• Settling the music and cutting picture to its structure, so changes of pace land on a beat or a phrase.
• Fixing the exact on-screen text: names, titles, callouts and any required lines, checked for spelling.
• Hitting the agreed running time, and planning the shorter versions that will be cut from this edit.

On explainers, clarity is the main job of the fine cut. For the Sigmoid MedTech explainers we made with FTA Global, the aim was to present complex healthcare and AI concepts in a format that is easy to understand. That is decided as much by the order and pace of a walkthrough as by the graphics laid over it.

Picture lock

The fine cut ends at picture lock: a written agreement that the timing of every shot is final. Lock is the hinge of the whole schedule. Graphics are animated to exact frames, colour is graded shot by shot and sound is mixed to the picture, so a change after lock can mean redoing work in all three. Small fixes remain possible after lock; restructuring is not, without extra time and cost.

What you see as the client

A cut that looks close to finished, still without the final grade, mix or animated graphics. Watch it at the size your audience will, read every word on screen and check every name and title. Then sign the lock only when you are ready to stop changing the edit.

When do graphics, colour and sound come in?

All three are finished after picture lock, but all three should start earlier. A calm post schedule designs them in parallel and applies them in sequence.

Graphics and motion

Styleframes, a handful of still designs that fix type, colour, layout and the style of movement, can be designed and approved during the rough cut. Animation happens after lock, timed to the final edit. On the Tata Play Fiber demo reels made for FTA Global, which show customers how to set up auto-pay, pause a service and raise a complaint, the motion graphics were instructional text callouts and brand assets laid over the footage, and the final assets had to align with Tata Play Fiber's brand standards. On instructional work the graphics carry the meaning, so their wording should be approved in the fine cut rather than discovered in the final review. Our motion graphics and 3D process writes the on-screen copy and fixes the styleframes before anything is animated, for the same reason.

Colour

Colour begins with a conform, which links the locked edit back to the full-quality original files. Then comes correction, which balances exposure and white balance and matches shots from different cameras so they cut together, and finally the grade, which sets the look. A standard HD deliverable is graded to ITU-R BT.709, usually called Rec. 709, the ITU recommendation for HDTV production and programme exchange. Grade on a calibrated monitor, then check on the screens your audience uses, phones above all. We go further into looks, skin tones and camera matching in the art of colour grading.

Sound

The sound pass has layers: a dialogue edit that cleans and evens out speech, noise reduction, the music edit, effects and atmosphere, and finally the mix that balances them all. Broadcast delivery usually comes with a loudness specification. The European Broadcasting Union's EBU R 128 recommends an average programme loudness of -23 LUFS. Online platforms and individual broadcasters set their own targets, so ask for the specification in writing rather than assuming one. For why sound deserves more of the budget than it usually gets, read our sound design essentials.

What you see as the client

The finished film, with graphics, grade and mix in place. This review is for polish and accuracy, not structure: spelling, logo versions, colour that sits right with your brand, music level against speech, and anything that looks or sounds wrong on your own devices.

How should review rounds be run?

Review rounds are where most post-production time goes, and most of that time is waiting. A good review process gets clear notes back quickly from the right people, in a form the editor can act on without guessing.

Agree the rules before the first cut

• The number of rounds per stage, written into the agreement: so many at rough cut, so many at fine cut, one at final. Extra rounds are possible, but they should be a choice rather than a drift.
• One person who consolidates notes. When brand, legal and leadership each send their own list, the notes often contradict each other and the editor cannot choose between them.
• A turnaround time for feedback, so the schedule holds on both sides.
• Who signs off, by name, at each stage, including picture lock.

How to give notes that work

• Watch the whole film once before writing anything, as a viewer would.
• Give a timecode for every note, ideally on a review link that pins each comment to its frame.
• Describe the problem rather than prescribing the fix: 'this section drags' leaves room for a better answer than 'cut this shot'.
• Separate must-fix items (facts, names, compliance lines) from matters of taste.
• Review on the device the audience uses. A vertical reel should be judged on a phone, not on a meeting-room screen.
• Do not reopen an earlier stage's decision unless something is genuinely wrong. Every reopened decision costs the stages built on top of it.

When an agency sits in the middle

When a studio works through an agency for an end brand, there are at least two sets of reviewers, and their notes need to arrive as one list. Agree early who merges them and who has the final word, especially on brand standards. In our corporate film process, every approver watches the rough cut and we merge their comments into a single list, so notes from brand, legal and leadership never compete for the same frame.

What does final delivery include?

Delivery is not one file. It is a set of files agreed at the start, named consistently and checked before they leave the studio. Put the delivery list in writing before the shoot, because some versions, vertical cuts in particular, depend on how the footage was framed on the day.

A typical delivery list

• The master: the full-quality film at the project's resolution and frame rate, in a high-quality format suitable for archiving and for making further versions.
• Web and social exports: compressed files for each platform and aspect ratio, landscape for websites and presentations, vertical or square for social feeds.
• Cut-downs: shorter edits for ads, events or social, cut properly from the edit rather than trimmed off the end of the master.
• Captions and subtitles: a separate subtitle file and, where needed, a version with subtitles burned in for silent viewing.
• A textless version: the film without on-screen text, so it can be translated or updated later.
• Audio stems: dialogue, music and effects as separate tracks, useful for translated versions and re-edits.
• Stills and thumbnails: frames or designed covers for each platform.
• Licences and credits: paperwork for music, stock footage and fonts, including any limits on where and for how long they may be used.

Checks before anything leaves

• Watch every file through to the end at full screen, not just the master.
• Check the first and last frames, and that nothing important is cut off in vertical versions.
• Confirm the audio plays on both channels and sits at the agreed level.
• Check that file names, version numbers and dates match the delivery list.

Archive and hand-over

Agree what happens to the project afterwards: how long the studio keeps the footage and project files, and whether you receive a copy and in what form. A short note at delivery saves a long search months later, when someone wants a new cut-down for the next campaign.

Where do post-production schedules usually slip?

Most delays in post-production have little to do with editing speed. They come from decisions made late, assets that arrive late and reviews that take longer than planned. These are the points we watch most closely.

Where time is lost

• Late or incomplete hand-over, especially sound files, screen recordings or product shots promised after the shoot.
• Slow feedback. A review that takes a week instead of two days pushes every later stage back by the same margin.
• Too many reviewers, too late. A senior stakeholder who first sees the film at the final review often asks for structural changes.
• Rewriting the script in the edit. If the message changes after the shoot, the footage may not support the new version.
• Missing brand assets: logo files, fonts, colour values or approved product names asked for on the first day and supplied on the last.
• Music and stock licensing left until the end, then found to be unavailable or unsuitable for the intended use.
• New formats requested after delivery, such as a vertical version of a film framed only for landscape.

Where money is lost

We do not publish rates, but the drivers of post-production cost are predictable: the running time and number of versions, the volume of footage to review, the complexity of graphics and animation, the depth of the grade and sound work, and the number of review rounds. Of these, changes after picture lock cost the most for the least screen time, because they repeat work in graphics, colour and sound at once.

How to protect the schedule

1. Agree the delivery list, review rounds and sign-off names before the shoot.
2. Send every brand asset and approver's contact in the first week.
3. Clear music and any stock footage before the fine cut.
4. Bring every decision-maker into the rough cut review, not the final one.
5. Treat picture lock as a real decision, and sign it only when you mean it.

None of this is complicated, but it has to be agreed before the first frame is cut. A post schedule that names its stages, its review windows and its sign-offs is one that both sides can hold each other to. More guides on planning and finishing films sit under video production.
