What's my job title and salary?

I can make videos (mostly on youtube) by writing the script and provide the voice over and also doing the montage and editing, i would like to know what my job title could be exactly, is it "Video Producer"? "Content Creator"? "Video Editor"? What's the difference between these job titles?

Also, what salary should i expect from a job like this if i worked full time and if worked as a freelancer and got paid per video

I hope i haven't angered the gods by posting in a wrong subreddit
