Subtitling SoftwareSSTG1Pro


Subtitling Software


SSTG1Pro is a software application for creating and editing subtitle data including text, timing and effect. It is used widely from freelance translators to major Productions.

Using only one interface to do various tasks like spotting, subtitling, and applying special effects, Italics, font, positioning, putting ruby alongside Chinese characters, emphasized marks “Bouten”, etc., and then confirming your data on the screen as subtitles, you are able to create a very high level screen translation by using SSTG1Pro.
Because the data files are so small, they can be sent by email.
If you use other optional functions, you may be able to transform the data into various data formats including DVD subtitle (Tiff), Blu-ray subtitle (PNG), DCP (XML), Advanced Authoring Format (aaf), etc.
Also, you can transform the data into Lambda CAP or NETFLIX CAP.
