> The assembly cut is the editor's first complete version of a film: every scene that was shot, placed in script order, built from the director's selected takes with little trimming. It is usually much longer than the final film and is the starting point for the director's cut.

## How the editor builds it during the shoot

The [editor](https://storiara.com/roles/editor) starts assembling while the camera is still rolling. Each morning the [assistant editor](https://storiara.com/roles/assistant-editor) syncs the previous day's [dailies](https://storiara.com/glossary/dailies), groups takes by scene, and loads the [lined script](https://storiara.com/glossary/lined-script) and the script supervisor's notes into the project. The editor then cuts each scene as it comes in, using the circled takes and the director's comments from set.

Because it follows the script, the assembly is a reference as much as a movie. If Scene 42A was shot on Day 11 and Scene 42 on Day 19, the assembly still plays them back to back, and that is often the first time anyone sees whether the two halves of a scene match in eyelines, wardrobe, or energy.

## What an assembly looks like on paper

A typical editor's report sent to the producers at the end of a shooting week might read:

| Scene | Script pages | Assembled length | Notes |
|---|---|---|---|
| 38 | 2 3/8 | 3:12 | Missing Maya's CU on "You knew." Pickup? |
| 39 | 4/8 | 0:31 | Fine |
| 40 | 1 6/8 | 2:40 | Plays long. Two takes of the wide used for the walk |
| 41 | 3/8 | 0:22 | Insert of the key not shot yet (scheduled Day 22) |

The running total matters. If the first 40 scenes cover 52 script pages and run 71 minutes, the assembly is pacing at roughly 1 minute 22 seconds a page, well over the rule of thumb of about a minute a page. Nobody panics at that stage, but it tells the director and producer early that the final film will need real cuts, and that a scene or two may not survive.

## Where people get confused

An assembly is not meant to be good. Editors leave in flubbed lines if they are the only coverage, keep every scene the script contains, and avoid making big structural choices, because those choices belong to the director's cut. Producers who watch an assembly and panic about the length are reacting to something that was never meant to be watched as a movie.

The other confusion is timing. Under the DGA Basic Agreement, the director gets at least ten weeks for the director's cut, or one day of editing for every two days of scheduled photography, whichever is longer. That clock starts after the editor's assembly, so a slow assembly pushes the whole post schedule and the [picture lock](https://storiara.com/glossary/picture-lock) date.

## How it feeds the rest of post

The assembly is the source for the [rough cut](https://storiara.com/glossary/rough-cut) and later the [fine cut](https://storiara.com/glossary/fine-cut). It is also where [pickup day](https://storiara.com/glossary/pickup-day) lists come from: missing inserts and coverage gaps show up here before the set is struck. A post supervisor will usually compare the assembly running time with the schedule in the [post-production workflow](https://storiara.com/blog/the-post-production-workflow-from-editors-assembly-to-final-delivery) and flag any scene whose footage count suggests a problem with the [shooting ratio](https://storiara.com/glossary/shooting-ratio).

## Frequently asked questions

### How long is an assembly cut?

Usually well over the finished length, because nothing has been dropped yet. Using the rough guide of a minute a page, a 100-page script that assembles at 1 minute 20 seconds a page runs about 2 hours 13 minutes.

### Is the assembly cut the same as the rough cut?

No. The assembly is the editor's version built during and right after the shoot. The rough cut comes after the director sits with the editor and starts reshaping scenes, dropping material, and changing order.

### Who sees the assembly cut first?

On a DGA picture, the director. The DGA Basic Agreement says no one other than the editor and the editor's staff views the completed assembly before the director does.

### Should the editor cut during the shoot?

Yes, on most productions the editor assembles scenes as dailies arrive, so the director and producers can catch coverage gaps while the cast and locations are still available.
