- 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, then download a new file.
An illustrative use case
A short product demonstration exported as a lower-bitrate WebM.
Select a real sample file you are allowed to process. Begin with a short, simple input before attempting a complex document or recording.
What to inspect in the output
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.
Where this tool stops
Real-time, lossy WebM recording. May lose audio. Maximum 30 seconds; output size is not guaranteed.
