Video Closed Captions via Compressor(repost)

We will be file segmenting ourselves the MP4 into M3U8 and TS files for VOD HLS streaming in IPAD.

We have an MP4 video file and the SRT file which we will provide you. The sample file will be of 3 minutes - 100 MB file.

Your task will be to provide us MP4 file back to us with closed captions embedded into it as CCLP. For this you need to use the software like FINAL CUT STUDIO and use COMPRESSOR add on for this. You can also use MACCAPTION tool.

Love,

Angel

## Deliverables

I contacted Apple and they specificaly mentioned CCLP.

They said that we can use FinalCutPro and use the addon of "Compressor".

Or, we can use third part closed captions tool like "MacCaption" from

If you are using the stream segmenter, you need to add CEA-608 closed captions to the MPEG-2 transport stream (in the main video elementary stream) as specified in ATSC A/72.

If you are using the file segmenter, you should encapsulate your media in a QuickTime movie file and add a closed caption track ('clcp').

One tool you can use to add closed captions to movie files or MPEG-2 transport streams is Compressor, included with Final Cut Studio. Compressor works in conjunction with Scenarist software to generate closed captions. See the Compressor documentation for details.
