AWS Service for converting closed caption files

I have some closed caption files in .scc format. I would like to convert them to .vtt format. I have tried several online services and libraries and have had mixed success. I was trying to identify an AWS service that would do the conversion (MediaConvert, Elastic Transcoder) but can't seem to figure out how to convert just a closed caption file when you don't have any actual media.

Do you know of an AWS service that can do the conversion? Can you point me at a resource for getting started.

If good .scc support is important to you and command line tool is ok, then you can use this:

php subtitles.phar input.scc output.vtt

ttconv can convert SCC files to text-based formats, like TTML, IMSC, SRT, VTT...

pip install ttconv
tt.py convert -i <input .scc file> -o <output .ttml file>

As a pure python library, it can be deployed on AWS as a lambda.

FYI, no caption only support in MediaConvert today. But there is workaround to achieve your goal. You can use the MediaConvert and create a small SD output rendition (would need to make sure the source file had a matching duration [or longer]) and use the SCC has a sidecar file, and output the webvtt file, with a throw away video file.
