Ah, but this could be the last system you need to learn.
It does have a learning curve.
As a creator you can create where you are most comfortable and the various front ends can pull, or not pull, depending on their general or specific content policies.
Nftshowroom.com is part of this and they do nft's.
I'm not sure if they are doing video nft's, I'm mostly a blogger, but I do have some art I made on it on the off chance that somebody buys it.
It may prove to be worth your time.
If you have any questions feel free to tag me, I'm something of an advanced player here.
I may not know the answer to all questions, but I know who to ask.
