Hello
flautash,
You seem to have missed the point here. The subtitle of this topic was a graphic based subtitle type, which had to be transformed into a text based subtitle (using Subrip).
Further there are several subtitle-utilities:
Vladimir's subsync a very simple and basic utility (which does the job it is supposed to do perfectly for only three types of subtitlefiles, i.e. SAMI, SubRib and MicroDVD or .smi, .srt and .sub; I must say I use it all l the time)
Then there is
SubtitleWorkshop as mentioned by you, which indeed can cope with a huge number of subtitle-types and has a lot more options and possibilities,
but there are more subtitle-utilities, e.g.:
SubMax
So now there is a choice!
