Teleprompter

Scroll your script over the camera preview while you record, with speed, size and mirror controls.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Teleprompter works

The camera and microphone are recorded with the MediaRecorder API; the script is shown on screen only and is never part of the recording.

Input: TXT. Output: WEBM, MP4.

How to use Teleprompter

  1. Drop a video onto Teleprompter.
  2. The first run downloads the ffmpeg engine (about 30 MB, once).
  3. Set your range, format or quality options.
  4. Process it (progress is shown live), then download.

Tips

  • Shorter clips and lower resolutions process much faster.
  • Processing speed depends on your CPU; plug in laptops for long jobs.
  • Keep the tab in the foreground while encoding.

Teleprompter FAQ

Are my files uploaded?
No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.
Is it free? Are there limits or watermarks?
Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.
Does it work offline?
Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
