SRT to SUB Converter

Your player wants MicroDVD SUB captions, which are frame-indexed rather than timecoded. The SRT to SUB Converter maps each SRT cue onto {startFrame}{endFrame}text lines, using your FPS to translate milliseconds into frame numbers.

Multi-line SRT cues are joined with the | separator so each subtitle sits on one MicroDVD line. A {1}{1}fps header is added by default so players know the rate; you can disable it. Pick the frame rate that matches the video and export your .sub.

• Frame indexing: timecodes become {sf}{ef} numbers.
• FPS mapping: choose 23.976, 25, 29.97, etc.
• Pipe lines: multi-line cues joined with |.
• FPS header: optional {1}{1}rate line.
• Lossless text: wording preserved.
• Private: runs in your browser.

1. Paste your SRT (sample preloaded).
2. Set the FPS to match your video.
3. Click Convert to SUB and copy or download.

Example 1 — Legacy player. A device only reads MicroDVD SUB.

Example 2 — AVI subtitles. Pair captions with a frame-based video.

Example 3 — 25 fps PAL. Set rate so timing matches.
