# Check quality before export

> Review the story, visuals, motion, media, accessibility, and technical health of a project.

Validation catches many technical problems. It cannot decide whether the video communicates clearly.

Use this checklist before the final render.

## Story

* The opening makes the subject clear soon enough.
* Every scene has a useful job.
* Claims are current and supported.
* The final action is clear.
* Nothing important appears only in narration or only on screen by accident.

## Readability

* Text is large enough at delivery size.
* Captions and labels stay on screen long enough.
* Contrast remains readable over moving backgrounds.
* Important content stays inside safe areas for the destination.
* No accidental overflow, clipping, or off-canvas element is visible.

## Motion and timing

* Entrances direct attention instead of delaying information.
* Several elements are not competing at the same moment.
* Cuts and transitions support the story.
* The ending completes cleanly.
* The project works when played from the beginning, not only when scrubbing isolated frames.

## Media and audio

* Every image and video loads.
* Crops and aspect ratios are intentional.
* Captions match the speech.
* Voice remains clear over music.
* No click, pop, abrupt cut, or missing final frame appears.

## Run the checks

```bash theme={null}
npx hyperframes lint
npx hyperframes check
```

Use snapshots for important moments:

```bash theme={null}
npx hyperframes snapshot --at 0,3.5,8
```

Studio can surface lint issues and copy them to your agent. See [Fix issues with your agent](/studio/lint-and-agent).

## Watch the exported file

The final check is the actual output. Confirm its dimensions, duration, format, audio, opening, ending, captions, and most complex transition.
