I hope you have some kind of written contract and they're not going to just do a runner when you hand over the work.
This almost happened to my brother recently with a record label and several videos he did.
He made them put a clause in the contract that stated he'd be paid the moment he handed over the videos.
When he did they were like " when the band pay US what they owe us then we'll pay you. "
Bro was like " No. You guaranteed in your own contract you'd pay up as soon as I delivered the videos. You're now in breach of your own contract ".
And they still weren't forthcoming. So then they went ahead and uploaded all the videos to YouTube.
So then my bro says : " You've not paid me for the videos - you've not bought the rights - therefore i still own all the rights and you're stealing my work and I can do whatever I want with these videos
and until you buy them off me - you can't legally use them."
They paid up pretty soon after
Record Companies.
He says he has the same problem with every label he works with. Dad and I suggested he make his own contract which they have to agree to - which states that he is to be paid
immediately upon receipt of the video.
No wonder majors are so fucked.
