Converting ass to srt

Advanced Substation Alpha (ass) is, as the name says, a more advanced version of the Substation Alpha (ssa) format. It supports many effects, a few examples are custom fonts, pictures, positioned text, colors, moving text and karaoke text. Srt doesn't support any of these things, and when converting ass to srt, all these effects are either removed or changed to normal text. Changing ass files to srt files usually works pretty well, except for the occasional overlapping text as a result of removing text position effects. You can learn more about the ssa and ass format on the Wikipedia page

Converting smi to srt

Synchronized Accessible Media Interchange (sami or smi) is an old subtitle format originally created by Microsoft. Smi files are barely ever used these days because there are far superior alternatives like srt or ass. Korea used to use the smi format to create subtitles for movies, most old Korean movies that come with subtitles use the smi format. Smi files support multiple languages in the same subtitle file, which should work fine when converting to srt.
