If the requirement is English, definitely add subtitles to your video, and also write your post in bilingual. Don't just upload a video with no accompanying text. Ultimately, you'll have to check with the community moderaters as each community has their own rules.
This will be the same as what you currently do for your music posts. However, I would recommend you not to tag people in your post. It is bad manners and very annoying to be tagged all the time, most people don't like it. Imagine if someone walked past your house every morning and shouted your name then walked away. Tagging a person serves very little purpose, if they want to support you, they would have followed you and your post will come up on their feed. Hope this helps
