You can edit and output HD and SD closed captions to tape, file, disc, mobile devices, and the web. Subtitle overlay files are created with alpha channel graphics to provide compatibility with your editing workflow.
Most popular NLE systems and capture cards accept Telestream encoded caption files and map the data to the proper location in the HD or SD video signal. We also support popular playout servers.
Extract closed captions from previously captioned video and re-export them to a variety of formats. Caption and subtitle data can automatically be conformed to match an edit decision list (EDL). Software also supports batch conversion and command line interface (CLI) scripting for automated workflows.
Use our software with a hardware encoder to caption a live broadcast or to live text stream to a web site. Or, use it to caption live YouTube streaming video. Captions can be input via speech recognition software or stenograph.

In addition, CaptionMaker and MacCaption support standard subtitling text formats for conversion to modern OTT subtitling files. Our MacCaption system is excellent for subtitling in foreign languages and has support for custom fonts, drop shadows, and Japanese Ruby annotation formatting. Convert your subtitling project to iTunes iTT for international delivery.
To caption a video, you need a transcript. Then you need to synchronize, or time stamp, the transcript so that each phrase is displayed at the right time. In the past, synchronizing captions was a labor-intensive, time consuming process. Your options were limited to doing the time stamping yourself, or paying a service on a recurring basis to do it for you.
Telestream offers an Auto Time Stamp (ATS) feature for our post production closed captioning software. This feature is a huge time saver for organizations who need to caption a large volume of videos for which transcripts are available. Automatic time stamping won't always be as accurate as a human being, but since it identifies potential problem areas in the file, you can achieve the accuracy of a human being without the tedium of manually timing the entire video. This can also help you quickly identify any discrepancies in the transcript.
ATS works very well for videos such as (but not limited to): speeches, lectures, presentations, meetings, training videos, etc. which have clean audio. It does not work as well if the audio has already been mixed with music or sound effects, so it is isn't recommended for captioning dramatic content, music videos, videos with lots of background noise or low fidelity audio, such as telephone or VoIP recordings.
