Convert SCC to VTT captions
Convert your subtitles in seconds — entirely on your machine. Nothing is uploaded: the file never leaves your device. CueForge preserves styling and positioning wherever VTT can express it, and shows you the exact loss matrix below before you commit. Reading Scenarist SCC (CEA-608) is a CueForge Pro feature with a 7-day free trial — exporting to VTT stays free.

What gets kept, what gets dropped
| Feature | SCC → VTT |
|---|---|
| Italics | Kept |
| Underline | Kept |
| Font colour | Kept |
| Positioning | Dropped |
| Display modes (pop-on / roll-up / paint-on) | Dropped |
SCC also encodes CEA-608 screen placement — the caption row and indent of every caption. No other format shares the CEA-608 caption grid, so conversion drops the placement; the line breaks and reading order are kept.
CEA-608 display modes (pop-on, roll-up and paint-on) describe how captions appear on air; CueForge folds them into plain timed cues, so the text and timing are kept but the mode itself is dropped.
VTT can additionally express Bold and Voice / speaker tags, which you can add in the studio after converting.
About SCC
Scenarist Closed Caption (.scc) carries CEA-608 (line 21) broadcast captions as hex word pairs of character data and control codes, timed on the 29.97 fps timebase with drop-frame or non-drop timecode. It supports italics, underline and the seven CEA-608 caption colours. Parsing SCC into editable subtitles is a CueForge Pro feature.
About VTT
WebVTT (.vtt) is the W3C captioning format for the HTML5 <track> element and web video. It builds on SubRip with cue settings for on-screen positioning, voice/speaker tags and CSS-class styling, and its timecodes use a period before the milliseconds (00:00:00.000), where SRT uses a comma.
