Need help with Mac video

Hi, I would like to get advice from fellow Mac video experts on an issue I am experiencing now. After a while, I got back to video chats and found that latest updated changed a bit regarding video subtitles/closed captioning. What are the best tools available now and how can I add these as seamlessly as possible to my videos? I am not looking for large how-to guides, just a list of things I should know about and available tools if there are any.

Hey there!
You can use Imovie, the video edit mac has for default or Affter effects or Premiere, those are pro video editors, Premier is easier to learn
