Automatic Time Stamping

About Auto Time Stamp

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.

Requirements

  • An accurate transcript.
  • A video with a high quality audio track (i.e. good signal-to-noise ratio).
  • CaptionMaker or MacCaption software

Results

  • Automatically synchronizes each caption; no need to manually time stamp captions. (This labor-saving option takes MacCaption's and CaptionMaker's existing feature of automatically breaking unformatted text into captions to the next level of automation).
  • The process is much faster than real-time (15 times to 30 times faster, depending on the speed of your computer).
  • The software automatically detects captions with poor synchronization and highlights them in red, so you can spot check and manually correct these captions if you so choose.
