A first-export guide · Windows x64
Turn an HTML animation into a video you can share.
You have an animation that works in a browser. Here’s how to make an MP4 for a presentation, a video edit or a social post, starting with a short test on your own PC.
1. Pick an animation and save the HTML
Browse HTMLHub’s animation library, open an effect and use its Download control. Follow any sign-in prompt shown. You can also use a local HTML file you made yourself.
Keep the original source file. An exported video is useful for editing and sharing; the HTML remains what you change when you want different text, colours or motion.
2. Check it in Chrome first
Open the saved file in Chrome. Wait for fonts, images and scripts to load. If the page is blank or the animation does not move, fix that before rendering.
- Keep referenced images, scripts and stylesheets beside the HTML in the expected folders.
- Check relative paths. Moving just the HTML can break a reference such as
../vendor/three.min.js. - Remote libraries need internet unless you have saved them locally and updated the paths.
- Give the animation container an explicit width and height.
3. Make a five-second test
Download the free Windows trial, open the app and choose your HTML file and an output folder. Start with these settings:
| Setting | Starting value |
|---|---|
| Resolution | 1920 × 1080 |
| Frame rate | 30 fps |
| Duration | 5 seconds |
| Output | H.264 MP4 |
| Encoder | A detected supported encoder, or CPU fallback |
Render one file first. A short clip gives you a quick compatibility check before spending time on a larger export.
4. Watch the output, then use it
Open the MP4 and check the motion, fonts, framing and duration. Import it into your video editor or presentation. For a vertical post, adapt your HTML layout to a portrait frame before exporting; cropping a landscape clip can cut off the subject.
Audio, remote media and interactive scenes need separate checks. A scene that waits for a click or login may need changes to start automatically in the renderer.
What a rendered result looks like
This Vanta Clouds clip was exported from an HTMLHub animation. It demonstrates that source animation; it is not a guarantee that every HTML file will render unchanged.

Blank frame: check missing assets, blocked network requests and the container size. Static animation: remove required clicks and inspect how it starts. Encoding error: try CPU encoding and a lower resolution. Different timing: random values, remote data or unsupported animation timing may need changes in your HTML.
