Free Online LRC to SCC Converter
Our LRC to SCC converter reads Lyrics input and produces Scenarist Closed Captioning output entirely in your browser. Source LRC timing ([mm:ss.xx] minute-second-centisecond) is converted to SCC timing (SMPTE HH:MM:SS:FF at 29.97fps). Styling and markup that the target format cannot represent are normalized or stripped, leaving valid, ready-to-use output. The conversion runs client-side, so your subtitle files are never uploaded to a server.

LRC vs SCC Technical Specifications
LRC
LRC (Lyrics) is a timestamped lyrics format used by music players and karaoke applications. Each lyric line is prefixed with a [mm:ss.xx] timestamp marking when it should appear. LRC files are plain text and are the standard for synced song lyrics in players such as MiniLyrics, Poweramp, and many karaoke apps. LRC has no end timestamps; each line ends when the next begins.
SCC
SCC (Scenarist Closed Captioning) is the industry-standard format for delivering CEA-608 (Line 21) closed captions to North American broadcast television and streaming services. SCC encodes caption text as hexadecimal byte pairs paired with SMPTE timecodes at 29.97 fps and begins with a Scenarist_SCC V1.0 header.
Format Differences
Conversion Troubleshooting & Gotchas
Practical solutions for player compatibility, character encoding, and timing synchronization
Subtitle timing drifts or appears out of sync on media players
Video files frequently differ in framerate (e.g., 23.976 fps vs 25 fps). If the timing drifts steadily, use our Subtitle Sync tool to adjust the global offset or framerate stretch.
Characters appear as garbled symbols or question marks (Mojibake)
Legacy files saved in Windows-1252, Shift-JIS, or GBK may render incorrectly. Our exporter standardizes output to clean UTF-8. Use our Subtitle Encoding Converter if the source file is corrupted.
Overlapping captions when multiple speakers talk simultaneously
Different formats handle overlapping dialogue differently. If your target player cannot render stacked cues cleanly, open the file in our Subtitle Editor to adjust individual cue timings.
Video editing software (Premiere, DaVinci, Final Cut) rejects the file
Professional NLE software enforces strict syntax rules. Our converter eliminates malformed line breaks and non-standard tags, producing clean, standardized files.

Absolutely. Every conversion runs client-side in your browser. No subtitle data, file contents, or metadata is ever transmitted to a server.
