# What Focus is

> Focus marks the exact place in your clip's frame that you mean — an Area around a subject or a Point on it — so Optic changes the right thing.

Words are good at saying *what* should change. Focus is for saying *exactly where*. With Focus you mark a place on a moment of your clip — the man on the right, the third car, the logo on a cup — and then point at that mark from your words. Optic then knows precisely which subject you mean.

Focus belongs to Optic. Marking is free; it never costs credits.

## Two kinds of focus

- **Area** — *"Draw around a region."* Drag a box around the subject. Use it when the subject is clear and you want to show all of it.
- **Point** — *"Tap to indicate a subject."* Tap on the subject. Use it for something small, or when a box would cover others. A point only needs to touch its subject.

Each focus is drawn in the shape of the ROUTIX eye, in its own colour, with its number — **01**, **02** and so on — and a name you can change.

## When you need Focus

- There is more than one subject your words could mean: two people, several cars, a crowd.
- The subject is small or partly hidden.
- You want to be sure which object you mean: *this* cup, not the one behind it.

If your words already make it clear — "the only dog", "the woman in the red coat" — you do not need a focus.

## How to open it

Focus opens once your clip is in and the range is confirmed.

1. Press **Focus** at the top left of your clip's picture. The clip pauses and the editor opens on that moment.
2. Choose **Area** or **Point** and mark the subject.
3. Press **Apply** to keep the focus, then **Done** to go back.

Then type `#` in the words box to point at it — see [Focus in your prompt](https://routix.studio/help/focus/focus-in-your-prompt).

## What a focus is not

The marks are only for Optic. They never appear in your film, and their colours are never painted into it.
