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 :)

Note: SE will now require 64-bit VLC/codecs on 64-bit operating systems!


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


- Installer version, .NET 4-4.5, 64/32-bit (will run 64 bit on 64-bit OS - so do use 64-bit codecs/VLC on 64-bit OS!)

- SHA1 Checksum: f9614303ebaa7e8283da95dead164fd6ba9004cf


- Portable version, .NET 4-4.5, 64/32-bit (will run 64 bit on 64-bit OS - so do use 64-bit codecs/VLC on 64-bit OS!)
- 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: e390032dd96b5fee16317339fcf86eaaa5df3ca7

For 64-bit systems, install latest version of LAV filters 64-bit or latest version of VLC 64-bit:
LAV filters releases
VLC 64-bit downloads (vlc-*-win64.exe is the installer)
