Greetings Rosy,
YouTube seems to be more forgiving for a 'Content ID claim'. Facebook, not so much. I recently tried posting a show and FB actually muted multiple portions of my show. I had to change the music. Sometimes FB just say:
I'm not even sure what this actually means or results in where it is muted. Now I just go ahead and post it on FB and where it gets muted, I just don't know. Maybe it is just an automatic reflex that FB uses, whether it really is copyrighted or not.
Always a challenge. Now, when I start a project, I put in the music I want to use and a few slides and throw it up on FB (as Private) just to see what they say. Saves me hours later having to re-do any added music.
