Record MP4 directly in the browser
Recent Chromium browsers can record straight to MP4, so a browser tab can be captured to a file that older editors, presentation tools and iOS workflows accept without any conversion. ReelCap Pro does exactly that — pick MP4 as the output format in the popup — and where direct MP4 recording isn't supported, it converts the finished take locally in the preview tab instead. Either way, the video never leaves your machine.
Doing it without an extension
- 1Record with a desktop app such as OBS configured to write MP4 — and accept that it captures the whole screen, not just the page.
- 2Or record WEBM in the browser, then install ffmpeg or find a converter you trust.
- 3Run the conversion over every recording you make, keeping originals and converted copies straight.
- 4Re-run the process each time you re-record a take.
Where that falls short
- Desktop recorders grab the whole window — tabs, bookmarks, notifications — so you inherit a cropping job.
- Installing and driving ffmpeg from a terminal is a real hurdle if you just want a demo file.
- Online converters mean uploading your recording to someone else's server.
Doing it with ReelCap
- 1In the ReelCap popup, choose MP4 as the output format — the option appears when your browser supports direct MP4 recording.
- 2Record as usual: countdown, pause and resume, stop from any tab.
- 3On browsers without direct MP4 support, record normally and press Export MP4 in the preview tab — the conversion runs on your device.
- 4Download the MP4 and drop it into any editor, slide deck or upload form.
Every step happens in your browser. Nothing is uploaded, and the export carries no watermark.
