Aegisub - powerful general-purpose crossplatform subtitle editor

[TheFluff]

Aegisub is an open source (BSD licensed) subtitling program. It's very buggy but it has a lot of features that pretty much all other subtitling programs lack so it's generally regarded as the least bad choice, especially among fansubbers.

As of this writing the last stable version is 2.1.7. Bleeding edge builds for Windows can be found here; automatic builds (built automatically at every SVN commit) for other platforms (and Windows as well, but with less features) here.

Very nice... I'm surprised I haven't come across this before.

How would this compare with Jubler?

On a quick look @ Jubler, I can see that it doesn't have a spectrum display for audio, which makes it nigh-useless for subtitle timing. It also seems SRT-centric and apparently doesn't support VFR.

They... aren't comparable really. Aegisub is a native app and not a Java one, for starters.
Aegisub doesn't rely on Mplayer for video, is enormously much more powerful for typesetting and timing, supports VFR, is scriptable (in Lua), is actually usable for creating subtitles from scratch, supports ASS overrides properly, etc etc etc.

Jubler seems to mainly have the advantage that it's a bit easier to adjust a script to an existing video that is slightly different from the original one. Also, it probably works properly on MacOS X, which Aegisub doesn't really. Yet.

Thanks for the feedback.

I've used Jubler for conforming and spotting subtitles for use in DVDSP under OS X and thought it performed reasonably well. I know it supports ASS and SSA subs, but to be honest I've never used these formats.

It was certainly cheaper than buying a copy of Lemony.

Actually I've been in the fansubbing business for a while, and I have to say that Aegisub is the most powerful tool around for these stuff, you can do amazing work with it..

In my opinion Aegisub is the best and powerful tool I had seen when it comes to subbing.

A new version (2.1. has been released with a lot of bug fixes. Also released for Mac OS X.
People who already have aegisub installed can download the update package they have on their website.
