Technical Details

  • Your SRT file is rendered onto every frame with ffmpeg's subtitles filter, so the text becomes part of the picture and shows on any player or platform.
  • Choose a font size of 16, 22, 28 or 36 px. Subtitles appear in ffmpeg's default style: white text with a dark outline at the bottom of the frame.
  • Because the picture changes, the video is re-encoded to H.264 at CRF 18, 23 or 28; the audio track is copied unchanged.

Frequently Asked Questions

What subtitle formats are supported?

Currently SRT (.srt) subtitle files are supported, which is the most widely used subtitle format.

Can I customize subtitle appearance?

You can choose the font size (16, 22, 28 or 36 px). Subtitles are placed at the bottom of the frame in ffmpeg's default white-with-outline style; position and colour cannot be changed.

Will this work with any video?

Yes, you can burn subtitles into MP4, MOV, MKV, AVI, WebM, and most common video formats.

Can I turn burned-in subtitles off later?

No. Burned-in (hardcoded) subtitles are part of the image. Keep your original video and SRT file if you may need a version without them.

My subtitles are out of sync. Can this tool fix that?

No. The timings come from the SRT file. Fix them in a subtitle editor first, then burn the corrected file.
