Recording video in the browser: requirements and performance tips
Learn which browsers to use, how real-time recording works and the performance tips to record animated videos without stutter.
Editor de Vídeo Online records video in the browser itself, with no software to install. That is convenient, but it has one quirk: recording happens in real time. Understanding how that works helps you avoid stuttering videos, unexpected file formats and interrupted recordings. This guide covers the requirements and best tips to record video in the browser with quality.
Recommended browsers
Use Google Chrome or Microsoft Edge, always up to date. To open the Editor de Vídeo Online file, right-click it and choose Open with your preferred browser.
Outdated browsers may record WebM instead of MP4. If that happens, update your browser or convert the file, as explained in how to convert WebM to MP4.
How real-time recording works
When you click Record video:
- The animation jumps back to the start and plays to the end.
- The browser captures each frame as it plays.
- When it finishes, the file downloads automatically (
editorvideo_date_time.mp4).
So a 30-second video takes about 30 seconds to record. In the Studio, Generate final video works the same way.
Clicking the button again cancels the recording.
Golden rules while recording
- Keep the tab open and visible. Browsers throttle background tabs, which can make the video drop frames.
- Do not minimize the window.
- Avoid other heavy tasks while recording.
- Close heavy programs (video editors, games, lots of tabs).
- Plug your laptop in: battery-saver modes slow down the processor.
Performance tips
| Problem | Likely cause | Fix |
|---|---|---|
| Video "skipping" | Overloaded computer | Close other programs and tabs |
| Recording slower than usual | Tab in the background | Keep the tab visible |
| Laggy preview | Very large image | Use images 1080 px to 2160 px on the long side |
| WebM file | Old browser | Update Chrome or Edge |
| Laptop heating up | Power saving or poor airflow | Plug in and use a firm surface |
Image resolution and size
Huge images (say, 6000 px) do not make the video look better on a phone, but they weigh on processing. A good range is 1080 to 2160 px on the long side. For Reels and Shorts, 1080 × 1920 is the standard.
When to use the Python version
If you need guaranteed exact 30 fps, lots of hand-drawing videos, or have a computer too slow for real-time recording, the advanced Python version renders videos without the browser. See how to batch-generate videos with Python.
Your work is saved
As you work, Editor de Vídeo Online saves everything in the browser. If the browser closes mid-project, reopening brings everything back and regenerates the animation. Only an in-progress recording has to be redone. Learn more in privacy and offline use.
Frequently asked questions
Does it work in Safari or Firefox?
