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. (Old videos.)

Dny238 has written a nice tutorial about Syncing Subtitles with Subtitle Edit :)

From next version SE will be compiled for .net framework 4 and use 64-bit where available, but a portable 32-bit .net framework version will still be released for a while.


For Windows XP users: SE requires Microsoft .NET Framework Version 2.0 - 3.5.


- Installer version, .NET 2-3.5, 32-bit (will run on win 64-bit too, but needs 32-bit codecs/VLC)

- SHA1 Checksum: 74a4067493d6a560b068508c297b862821c476ff


- Portable version, .NET 2-3.5, 32-bit (will run on win 64-bit too, but needs 32-bit codecs/VLC)
- This also works on Linux (when mono/mono-form/etc is installed)
- Linux users should also look here: http://www.sub-talk.net/topic/2751-subtitle-edit-for-ubuntu-troubleshoting-tips-and-tricks/

- SHA1 Checksum: abda13df8a325adcc26588ec418948913ae18ced


- Portable version, .NET 4-4.5, 32/64-bit (will need 64-bit codecs/VLC on 64-bit machines)
