So! I don't think any free programs will let me do very much effects but.. it's worth a shot! I want to put my own subtitles into videos such as this one

I write my own lyrics to song like these and so I want to add in my subtitles. I want to make my subtitles as close to the original Japanese subtitles as I can! If you can help please tell me!

I already tried Aegisub.. I can't figure out how to use ANY effects in it! All the tutorials are only for subbings anime episodes so I nothing very useful to me. But if you can help with that then please do help! Thank you to anyone who helps!^^
