"Multi Translator is a small free utility for translation of text or subtitles (SubRip .srt).
At the moment it is possible to translate from Danish to Swedish (dansk til svensk). However, it is possible to add more languages.
Please note that translated material will still need manuel correction."
"ubtitle 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."
