Video tools / practical guide
Re-record a short clip at your chosen width and bitrate to make a WebM version.
A practical starting example
A short product demonstration exported as a lower-bitrate WebM.
Re-record a short clip at your chosen width and bitrate to make a WebM version.
Use this as a small trial before applying the operation to your real input. A sample illustrates the workflow; it does not promise a specific result for every source file or device.
How to use Video to smaller WebM
- Choose the appropriate input file. General limits are 30 MB per file and 100 MB total.
- Review the options before running: Start time (seconds): 0 · End time (seconds): 2 · Width: 640 · Video bitrate (bits/second): 500000
- Inspect the preview or result. Use the application’s copy or download option when it is available.
Prepare the input
Choose an input matching video/*. Review the tool’s file-size limits before selecting a large batch.
Review the available controls
| Control | Starting value | Review before processing |
|---|---|---|
| Start time (seconds) | 0 | Check this against your intended video to smaller webm result. |
| End time (seconds) | 2 | Check this against your intended video to smaller webm result. |
| Width | 640 | Check this against your intended video to smaller webm result. |
| Video bitrate (bits/second) | 500000 | Check this against your intended video to smaller webm result. |
How to decide whether the result is useful
Compare playback, actual file size and audio with the original. Bitrate is a target for the re-recording process; a short or already compressed source may not shrink.
- Compare the output with the unchanged source.
- Check the destination requirement before copying, downloading or uploading it.
- Open the downloaded file in the receiving application and check its actual type, size and contents.
- Use a second representative sample if the first does not cover the difficult part of your input.
Limitations and troubleshooting
Real-time, lossy WebM recording. May lose audio. Maximum 30 seconds; output size is not guaranteed.
If the output does not match your intention
Return to the original copy, review the selected input and controls, and repeat with a smaller sample. If the embedded view is unavailable, use the direct tool link at the top of this page. Browser support and device memory can affect file-based workflows.
Questions about this tool
Is this lossless video compression?
No. It records a new lossy WebM in real time, with bounded clip length. Sound capture depends on the browser and must be checked in the download.
Can I use the tool from this guide?
The main button opens the working tool on its Tabaix subdomain. An optional embedded view may be added to this guide; the direct link remains available for larger screens, downloads or browser compatibility.
What should I keep before changing the input?
Keep an unchanged source and record any controls you chose. That gives you a comparison point and lets you repeat the task without replacing your original.
