Hello everyone my name is Aviv and I'm on my first steps as a media composer. I want to clarify that this is my first serious hired job, and I am not familiar with all the professional terms of copyright/license music, so I may sound "noob" in my explanation/questions. 😅 I've been hired by a video production company to compose 1 minute of custom music for one of their clients commercial. The client asked for a couple of bids: 1. Using the music in their digital assets for unlimited time and one year of sponsored campaigns online. 2. Using the music for worldwide TV for one year. 3. Using the music freely as they want, they called it "Total Release" (I dont even know if thats a term in this business) but my guess is that they ment for a buy-out. Anyway the client chose for now only bid offer number 1. I've been paid by the video production company the amount we agreed on the bid offer number 1. *I haven't signed with them any contract/agreement so far* So my question is: Should I send any kind of agreement that confirms that my music is being used as we agreed and that I own all the rights? If so, I hope someone can teach me from their experience how to pronounce that kind of agreement. I will also like to know how I can preserve some kind of rights if they will choose to expand for bid offer number 3. I hope I've managed to be clear with my explanation. Thank you so much for your time!
