How to convert SRT to SCC

Convert SRT to SCC online. CutConvert encodes your SRT subtitles as Scenarist Closed Caption files: real CEA-608 pop-on captions with drop-frame 29.97 timecode, the format US broadcast and iTunes delivery specs ask for.

  1. Add your SRT file

    Drag the .srt onto the drop zone. Line breaks in your cues are kept; long cues are wrapped to the 32-column caption grid automatically.

  2. Convert SRT to SCC

    Press Convert. Each cue is encoded as a CEA-608 pop-on caption with character set, positioning codes, and parity bits included, then scheduled frame-accurately in drop-frame timecode.

  3. Download your result

    Download the converted file instantly, or a single ZIP archive when you convert a batch of files.

SRT file and SCC broadcast captions, explained

Broadcasters and iTunes-style delivery specs require Scenarist SCC, but NLEs export SRT, and the desktop tools that bridge the gap cost hundreds to thousands of dollars. This converter does the encoding properly: CEA-608 character mapping (accents and music notes included), 32-character rows, up to 4 rows per caption with automatic splitting, and caption loads scheduled around the 2-bytes-per-frame 608 bandwidth so display times land on the right frame. The encoder is verified by round-tripping a full broadcast movie against a reference decoder.

Turn SRT subtitles into broadcast-ready Scenarist SCC: CEA-608 pop-on captions, drop-frame 29.97 timecode, verified against a reference decoder. It is free to start, encrypted in transit, and converts a whole batch into one ZIP — sign in when you need large, high-volume jobs.

SRT to SCC FAQ

What kind of SCC does this produce?

Channel 1 (CC1) pop-on captions with drop-frame 29.97 timecode, the standard style for scripted broadcast and iTunes delivery. Roll-up output is not currently offered.

How are characters SCC cannot represent handled?

CEA-608 has its own character set. Standard and special characters (accented vowels, ñ, ç, ½, ♪) are encoded natively; characters outside the set, like smart quotes, em dashes, and some capitals with diacritics, are transliterated to their closest 608-safe equivalent, and anything unmappable is reported in a warning.

What happens to long subtitles?

A pop-on caption holds at most 4 rows of 32 characters. Longer cues are wrapped on word boundaries and, when they still exceed 4 rows, split into sequential captions that share the original cue's duration.

Why does a warning say a caption displays late?

CEA-608 transmits two bytes per video frame, so a full caption takes up to ~2.5 seconds to load. If your cues are so dense there is not enough time to transmit a caption before its start time, it is scheduled as early as physically possible and the delay is reported, the same constraint any 608 encoder faces.

Is it free?

Free to try on short files (about 10 minutes of program). Full-length caption files need a one-time $3 conversion or a paid plan, still a fraction of desktop captioning software.

Questions, answered

Where are my files processed?

In your browser. The converter runs on your own machine and the file never leaves it; the site only records that a conversion happened. CutConvert never sees, stores, sells or shares your media.

Is it free? Do I need an account?

About an hour of footage per file is free, on every converter: 100 KB of subtitles or captions, 500 KB of Word transcript, 2 MB of transcript JSON, 1 MB of Resolve project, 5 MB of Final Cut XML, with Premiere projects and Avid AAF a little under the hour. Guests get five conversions a month, a free account has no monthly cap within those sizes, and above that project-to-project transfers are $5 per file. Every other conversion is $3, including project files to captions, reports or cut lists, and captions or transcripts into an editor. Pro is $9 a month ($90 a year) for every file type up to 50 MB; Studio is $19 a month ($190 a year) for files up to 500 MB. Paid-file access lasts 24 hours.

What do I get when I convert multiple files?

Drop several files and you get back one ZIP archive containing every converted file. Convert a single file and you get that one file back, no ZIP. Tick extra formats under the output chips and the same ZIP carries every one of them, and a file counts as one conversion whatever it is written to.

Which formats are supported?

Timelines: Premiere .prproj, DaVinci Resolve .drp (as exported, or gzip- or Zstandard-wrapped), Avid AAF and Final Cut FCPXML in; FCP7 XML, FCPXML, Resolve .drp, CMX 3600 EDL and shot-list CSV out. A Premiere or Final Cut edit travels with its transitions, markers, titles, opacity and scale keyframes, clip volume, speed changes, nested sequences, bins, audio channel routing and each file's own frame rate, wherever the output has a place for them; an Avid AAF brings its transitions, markers, clip levels with their keyframes, muted tracks, nested stacks and each clip's own rate. Captions and transcripts, read and written: SRT, WebVTT, SBV, ASS, TTML, DFXP, iTT, SCC, MCC (a second 608 channel comes out as its own file), EBU-STL, Avid caption TXT, CapCut drafts of any size, timed CSV, Word, plain text, Whisper, WhisperX, AssemblyAI, Deepgram, Rev.ai and CapCut JSON, TwitchDownloader chat logs as a chat replay, Premiere transcript JSON and .prtranscript, Rev, Otter and Word-style transcripts, with italics, colour, placement and speakers kept where the output can hold them and measured word timing into Premiere. EDLs become event CSV reports. The capability table lists what every pair keeps.

Can I pick a frame rate?

Yes. For EDL and Avid caption output you can choose 23.976, 24, 25, 29.97, or 30 fps, or let CutConvert auto-detect it from your source.
