Does Burn-In Keep Editable Captions?

No. Burned text becomes pixels. Export and retain the SRT so captions remain editable and can be provided as an accessible sidecar.

Why Does Export Take The Video's Full Duration?

The browser records the styled canvas in real time so it can combine local video, timing and caption drawing without uploading the source.

The exporter adds the first capturable source audio track when the browser supports media capture. Review the finished file because browser and codec support vary.

Open a video, then import or paste SRT/WebVTT captions.

Burn-in records in real time and exports browser-compatible WebM. It uses the first capturable audio track when available. Test sync, line wrapping, safe areas, frame rate and platform delivery requirements; keep the editable SRT as the accessibility master.

What Is the Subtitle Burn-In & Caption Safe-Zone Studio?

A timed caption finishing workspace with local video playback, SRT/WebVTT parsing, cue seeking and editing, scalable font and outline, background box, maximum line width, vertical placement, title-safe overlay, editable SRT export and browser-recorded WebM burn-in.

How It Works

Open a video and caption file, scrub to cues, correct timing or text in the table, style the overlay and confirm line wrapping inside safe zones. Keep the SRT master, then record a captioned WebM in real time when a hardcoded preview or delivery is needed.

When to Use It

Create review copies, social captions, accessibility previews and burned-in reference files. Final broadcast or platform delivery should follow the recipient's caption format, frame-rate, safe-area, language, audio and codec requirements.
