Makes it easy to create coloured, awesome subtitles using your editing software. If you're using Resolve (and probably Premiere works too), write your subtitles with each person on their own track, and one for other audio. Then, export them as SRTs without formatting. This tool takes in as many as you've got, and returns a file with all the style info applied.

Here's some hints:

• Seriously, export your .SRTs without formatting. This tool will take your raw text, which would include <i> and <b> tags, which might cause issues in the final file.
• In general, select a different color for each speaker. It's common to use white for your host, then yellow, blue, lime, and pink in that order.
• Use the prefix tag to denote the speakers. It'll add a "[NAME] - " tag to the start of their messages when they speak for the first time, and if someone else has spoken since their last subtitle. This helps in the case of color blindness. Leaving this blank removes the tags. You can do this manually with your .srt files, however the tool will compute them intelligently for you.
• Any files with the environment flag set will be rendered in white and italic.
• This tool generates .SRV3 files, which is a format used exclusively by YouTube. I did try other standards like WEBVTT and TTML, but the colors just didn't, so I'm working with what I've got. I may come back and add other formats later.
