Cut
Assemble a sequence's takes into one finished film, then mix, grade, caption and download it.
The Cut screen is where a sequence becomes a finished film: you order its takes on the timeline, balance the sound, set the look, add captions and download the result. To reach it, open a sequence and click Open in Assembly at the top of the timeline dock. The browser on the left holds what you can add, the viewer and timeline sit in the middle, and the inspector on the right shows the details of whatever you select, or of the whole sequence when nothing is selected.
Takes
Every take of every shot in this sequence, grouped by shot. Drag one onto the timeline to use it, or click it to select the clip that plays it.

- Click Takes at the top of the browser.
- Narrow the list with the tag filter if you are looking for takes you have marked.
- Switch between Filmstrip and List to see pictures or a compact list.
- Drag a take onto the timeline to place it, or click it to select the clip that already plays it.
- Shot headings group the takes by the shot they belong to.
- Take label shows the take's number and the model that made it.
- A take that is still being made says so and cannot be dragged until it is ready.
