I would like to just contact the moderator who closed this question but I don't know how, so I'm posting here.
The moderator is saying that this question is a duplicate, but I specifically am asking users how to hard code subtitles into a video. The other one is only asking how to sync the files, and just happened to receive answers that are similar to my asked question about editing. But still, there is no answer on how to hard code the subtitles.
I suggest this gets reopened, if you disagree please tell me why, but I think this question is useful and people who have a similar problem can now easily find my question with answers. As opposed to finding the wrong question with the right answer.
