How to convert ASS to SCC

  1. Add your ASS subtitles

    Drop ASS (SSA, SubStation Alpha) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. SCC is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the SCC, or download everything as one ZIP if you converted several files.

Why ToAny

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

ASS to SCC: what to expect

ASS styling is not understood by simple players, and it is lost when converting to plain formats. SCC is what broadcasters, DVD authoring tools and video editors accept as closed captions. ASS is at home in anime and karaoke subtitles with fonts, colours and positioning; SCC is the usual choice for closed captions for US and Canadian broadcast, DVD and some streaming deliveries.

The text is read as UTF-8 or UTF-16, whichever the file is. An older file in another code page is read using the charset it declares, or as Windows-1252 if it declares none, so accented letters in an unlabelled legacy file can come out wrong. A file that is not text, such as the picture-based subtitles of a DVD, is refused instead of being converted to nonsense. Of the styling, only italic, bold, underline and the position on screen (top, middle or bottom, left, centre or right) travel between formats; fonts, colours, outlines and effects do not. Each line takes its italic, bold, underline and alignment from its style and from override tags; drawing commands and karaoke effects are ignored. Captions are written as CEA-608 pop-on captions on channel CC1 at 29.97 fps drop-frame: lines are wrapped to 32 characters and at most four rows, characters the standard has no code for become the nearest plain letter or a question mark, and colours are not kept. A caption needs a moment to load, so cues closer together than that are painted on as they are typed or appear a few frames late. Input denser than the channel can carry (a byte pair a frame) loses the captions that could not start within two seconds of their time, and a cue that starts while another is showing cuts that one short.

ASS vs SCC

ASS

ASS/SSA subtitles

ASS adds styles to subtitles: fonts, colours, outlines, shadows, exact screen positions and animation effects. Fan-subbed anime and karaoke use it heavily. SSA is the earlier version, and the .ssa extension is read as the same format.

Opens in VLC, mpv, Aegisub and most fan-subtitling and media-server software; not browsers

SCC

SCC closed captions

SCC stores the CEA-608 caption data of line 21 video as lines of hexadecimal byte pairs, each line starting at a timecode, one pair per video frame. It is limited to 32 characters on up to four rows, a Latin character set and a frame-based clock (usually 29.97 fps drop-frame), but it is what American broadcasters and many video editors expect.

Opens in Broadcast and DVD authoring tools, Premiere Pro, Final Cut Pro, DaVinci Resolve and VLC

Questions

Are my subtitles uploaded anywhere?

No. The ASS to SCC conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting ASS to SCC?

No further quality is lost: SCC stores the decoded audio exactly. The result is identical in content.

Can I convert several ASS files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert ASS to SCC on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the ASS file, press Convert and save the SCC. There is nothing to install.

Is there a file size limit?

Yes, but a subtitle file is small. Files up to 50 MB are accepted, far more than any real subtitle file. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
