Free Online SBV to SCC Converter
Our SBV to SCC converter reads SubViewer input and produces Scenarist Closed Captioning output entirely in your browser. Source SBV timing (H:MM:SS.mmm comma-paired start,end) 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.
Input Format
SBVSBV (SubViewer) is a simple subtitle format popularized for YouTube captions. Each block has a single timestamp line with comma-separated start and end times in H:MM:SS.mmm format, followed by subtitle text. SBV uses [br] for line breaks and the bracket tags for styling, and has no sequence numbers or file header.
Output Format
SCCSCC (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.
