Closed Captioning

[8591paul]

Does anyone know of a program for PC that converts to closed captioning like tv's do?

 

[Horschallen]

I am deaf and I do not think anything like a program to add closed captions exists at this time.... unless I am mistaken. The Federal Communications Commission has been involved with those types of issues, but I have not kept up with what is going on. It is a pressing issue at this time and for a while. I would love to see all those news online captioned. Paul, if you want to learn more about it, please feel free to PM me and I will gladly try to look into it more for update info.

The captioning on TV broadcasts is actually encoded into an invisible section of the video signal. The information is decoded by your TV and displayed as text. There's no actual voice recognition or anything happening in your TV. It's all typed in by a human being at some point.

Closed captioning is not provided in most (or any!) internet video content. Most formats don't even have the capability to embed captioning data. Quicktime does, but I'm not sure about other formats.

Because internet video is typically lower resolution than TV/DVD, heavily compressed, and also has extraneous video lines removed (the part where the captioning data is embedded) there is no way to extract any existing caption data from web video.

Existing captioning on DVDs can be embedded into Quicktime conversions using HandBrake, a great DVD conversion tool. The captions are even viewable on iPhone and iPod Touch. Handbrake is available for all the main current OS's, free!

the .srt file format is around since years, and most modern media player can use it. basically it's a text file with the closed captions, and some information when to display them.

or are you talking about hard encoding the captions into the video file?

That would be great, I would like that too.

Perhaps I misunderstood the question, but yes, I was referring to extracting subtitle information previously encoded into a video signal.

SubRip files (.srt) are certainly an option if available, but I can't say I've ever seen them offered on a website - probably more to do with the fact that I haven't been seeking them. Presumably there are specialist sites which offer video with SubRip files.

there are hundreds of websites one of the biggest:
