Line 21 VBI captioning is indeed the standard for standard definition, baseband digital and analog video. It's also and the standard for some interchange formats like D10 / IMX, both of which use MPEG-2's 4:2:2 profile to encode a 720x512 image for NTSC, which includes all VBI data (CC and VITC etc).
However, in the compressed domain, an end user would be unlikely to see captions in this form. Quite frequently the 608 (or 708) data packets are stored in the MPEG-2 user data, or as H.264 SEI messages. ATSC A/53 defines both methods.
As an aside, things are a bit different in the HD world. Baseband HD video is usually transported over HD-SDI. In this scenario, captions and other metadata are stored in the vertical ancillary (VANC) data. This VANC data can be partially (or sometimes completely) retained when capturing baseband HD-SDI into a file. However, it's more common for captions to instead be extracted from the VANC, and inserted into MPEG-2 user data, H.264 SEI messages, or a standalone caption file during capture.
Most of that is fairly off-topic, but I find captions interesting (and endlessly frustrating).

CCExtractor supports MKV files, and it obviously supports EIA-608. Fl studio hypersonic 2 download. However for MKV it only supports.srt, while EIA-608 must come for example from TS files or other kind of MPEG files. So while we have support for both MKV and EIA-608, we can't extract subtitles in EIA-608 inside MKV files. Extract EIA608 closed caption to srt. Hi, I have a.ts file and if I play it on VLC I can see 4 tracks for closed caption and if I select track 1 I can see the closed captions on the screen. I'm trying to extract those to an srt file but I didn't find a way. I can pull out the EIA-608 captions but not simultaneously add them as a stream in the final TS file while transcoding video and copying audio. Im sure there is some way to do it. I just can't figure out how. Activate mpeg 4 encoding in pinnacle studio 10. You are wrong, there is currently no way.
