My attempt at an answer (corrections gladly received)
Data is data. If you have access, you can store it somewhere else and it is then yours. Video is not any different than cat pics.
If you want to copy it on SAFEnet, this can be done. Someone will have to pay to store the second copy. But if they have access they can download the file and store/share it somewhere else. There is no way to give access to data and at the same time prevent it from being copied away from you. At the extreme, look at the DRM arms race for media… all attempts to prevent copying have failed. The only copyprotect left standing is physical dongles that require a server to decrypt key parts of code.
To explicitly answer your questions:
Any data can be copied if one has access to it. Copying it to a new owner on SAFEnet will require paying more storage fees. You can set up permissioned websites on SAFEnet, but same as the regular internet, once access is given to data, you cannot prevent it from being copied.
Coin creation or division? This question indicates a misunderstanding to me. Coins are tied to resources, not the value your data may have in meatspace. Once on SAFEnet, it is simply ownership, access or no access. If you stream it, your access can be revoked. If you copy it and pay fees to store the data again, then you can do what you will with it.
