i want to store a video in an permanent, unalterable, easily accessible, way. the blockchain is perfect for that.

No. It isn't.

i guess i could sign the video and save that sig to the blockchain, use that as proof the video is authentic. but that feels like a work around.

That's what hashes and signatures are for. They provide a way to represent some data without needing the entire data set.

you can't argue that the blockchain isn't the best way to store information is a permanent, unalterable, easily accessible, way.

but i guess the information on the blockchain should be the type that is used to authenticate something without relying on a 3rd party.

we keep track of the BTC TX, so we can authenticate TX's without a 3rd party.

a hash can be used authenticate the video, or whatever large file.

80 bytes per transaction isn't much at all...
