HELP
IMPORTANT
Browsers often cannot record MP4. Many only record WebM.
This page tries MP4 and tells you if it’s supported.
No uploads • runs locally.
STEPS
1) Load a WebM
2) Press START (records playback)
3) Press STOP (or wait to end)
4) Download MP4 (if supported)
ESC returns to PAGE 1
IF START FAILS
Your browser likely can’t output MP4.
Use WebM output instead (P741).
For reliable MP4, use desktop software.
QUALITY NOTES
This re-encodes; quality depends on device encoder.
Audio capture may be limited by browser policy.
