See here for how images can be stored in a blockchain.
Now imagine multiple images being stored in a blockchain like Bitcoin, or Etherium, or any one of the many blockchains. Each image being a single frame of a video file.
Images can be saved as binary values of 1's and 0's.
Those values can also be encrypted so that no one can just stumble across them randomly. Those can then be converted and stored in the data that makes up the actual blockchain.
Blockchains can store all transactions with information such as the date and time that particular transactions occurred. This data can not be removed from the blockchain and are for ever, basically.
A blockchain is a distributed database that stores massive amounts of information in an extremely long string of values (numbers and letters) that can contain all sorts of information like financial transactions, date and time data, contract data, and even 1's and 0's that form the basis of digital image formats as well as digital video formats... basically any data you want to store. If data can be digitised, it can be stored within a blockchain.
Some blockchains are designed to store things like images or videos. That's where you get your NFT's. It's a digital verson of an image or a certificate or something that can also save details on the owner of that NFT and also any transactions of that NFT, like who sold it to who for how much and when. Also data like who every previous owner was.
Basically, a blockchain can be used as a massive distributed database and can contain any digital information you want with exact timestamps as to when that digital information was added to the blockchain.
Older blockchains such as Bitcoin don't really have any uses other than transaction information of Bitcoins changing hands. But newer blockchains can store anything that the blockchain designer wants to store, such as contract information or possibly card movements in each hand for a game of Poker (in the case of blockchains designed for gambling).
Blockchains store data, it's up to the program that runs each blockchain to use the data stored within the chain of blocks, i.e. the blockchain.
I've probably rambled a bit, but I hope that helps to explain some of it.

No problem mate, glad I could help.
