Add Subtitles to Video
Burn SRT or VTT subtitles into video
Upload a video and an SRT or WebVTT subtitle file, preview timing and placement, then render an MP4 with hardcoded subtitles.
Choose font size, position, alignment, colors, outline and background box before server-side subtitle export.
✓
Browser-side media tools are useful for quick analysis, previews and lightweight exports.
✓
Large video and audio files may need time to decode; smaller samples work faster in the browser.
✓
When the result is a command, run it on a machine with the required media tools or model installed.
✓
Review generated WAV, PNG, CSV and command outputs before using them in production workflows.
✓
Fullscreen mode on tablets and desktops gives more room for waveforms, tables and video previews.
✓
For final broadcast, podcast or advertising delivery, verify results with professional media tools too.
