# Setup

> Check your file format and size before uploading.

Unlike Capture Screen Recording, this method doesn't require the Chrome extension - just a video file that meets Velo's requirements.

## Supported formats

Velo accepts the following video formats:

* **MP4** - the most universally compatible format, recommended for best results
* **MOV** - common output from QuickTime and iOS screen recordings
* **WEBM** - common output from browser-based recording tools

## File size limit

Your file must be **under 1 GB**. For most Velos this isn't an issue, but if you're uploading a long or high-resolution recording, consider trimming it down before uploading - or compress it using a tool like HandBrake or Clideo.

## Tips for a good upload

**Use the highest quality you have.** Velo generates zooms by analysing the video, so a crisp recording produces better automatic zoom placement than a compressed or blurry one.

**Trim unnecessary content beforehand.** If your recording has a long lead-in before the walkthrough starts, trim it before uploading. You can also cut in the editor, but starting with a clean file saves time.

**Make sure the recording shows actual product usage.** Velo's AI generates the narration script by analysing what's on screen. Recordings that clearly show UI flows and interactions produce better scripts.

## Starting the upload

From the Velo dashboard, click **Generate a Velo**. On the "Create your Velo" screen, click the **Upload a Recording** card.

You're now ready to upload your file - head to [Uploading](/upload-recording/uploading) to continue.
