> Scenes, trimming, effects and captions — refining the cut without a timeline.

# Compose and edit

Editing in Decodx happens at the scene level, not on a timeline. You reorder, re-cut and rewrite
scenes; the video re-assembles itself.

## Light and advanced compose

Two views over the same project:

- **Light** — the scene list, the script, and the essentials. Where most editing happens.
- **Advanced** — per-scene control over sources, timing and effects.

Switch freely; they are views, not modes, and neither loses work.

## Working with scenes

Add, reorder, duplicate and remove scenes. Because scenes are independent, reordering never
invalidates a render — the scenes you didn't touch are reused.

## Trim, crop and aspect ratio

Trim a scene's in and out points, crop the frame, and set the project's aspect ratio for the
destination — landscape for a docs page, square or vertical for social.

## Effects

Applied per scene:

| Effect | Use it for |
|---|---|
| **Zoom** | Drawing the eye to the part of the screen that matters |
| **Callout** | Labelling a control or a result |
| **Spotlight** | Dimming everything except one region |
| **Blur** | Hiding names, emails, account numbers, anything that shouldn't ship |

Blur is the one to be deliberate about: check every scene before publishing, not just the ones you
remember.

## Captions and chapters

Captions are generated from the narration script, so they always match what's said. Chapters are
derived from your scenes — another reason scene boundaries are worth getting right.

## Templates

Save a project's structure, voice and brand settings as a template and apply it to the next video.
This is how a series stays consistent without anyone remembering the settings.

## Comments and review

Leave comments on a project, mark review status, and see the activity trail. Folders keep a growing
library navigable.
