This python tool provides a subtitle' handler, that allows you to merge subtitles and change some features, like position, color and so on.
The basic usage merge two subtitles and shows them at the same time on screen, as the example below:
Portuguese and english subtitles
The above subtitle position is set by default
For that use:
$ python strusion.py -S portuguese_sub.srt english_sub.srt -o merged_sub.srt
Add -x -y in the command:
$ python strusion.py -S portuguese_sub.srt english_sub.srt -o merged_sub.srt -x 192 -y 48
Note that changes only the above subtitle
Add -x -y in the command:
$ python strusion.py -s movie_sub.srt -o movie_sub.mod.srt -x 192 -y 48
Note the use of -s for handling just one subtitle
Add -d in the command, then put the millisecs and subtitle:
$ python strusion.py -d 2500 unsynchronized_sub.srt -o synchronized_sub.srt
