Subtitle Edit

 Here's a program I use almost daily, either to edit subtitles, or to make subtitles. It's pretty nice to add subtitles to a movie or home video that doesn't have subtitles. Maybe you have a movie in a different language with no subtitles? Subtitle Edit will not only make subtitles for the movie, but it will also translate into the language of your choice.

Subtitle Edit Overview:

Subtitle Edit is a free (open source) editor for video subtitles - a subtitle editor :)

With SE you can easily adjust a subtitle if it is out of sync with the video in several different ways.

You can also use SE for making new subtitles from scratch (do use the time-line/waveform/spectrogram) or translating subtitles.

For a list of features see below or check out the Subtitle Edit Help page.

On my blog you can download latest beta version and read about/discuss new features.

Also, you can watch a few videos about installing and using Subtitle Edit.

A Subtitle Edit dll (LibSe.dll) is available for programmers (BSD New/Simplified license). Compile it from source code or use the NuGet package.
