One (small) thing that isn't correct is that your Bitcoin address is not the public key. It's actually hash of the public key [1], using RIPEMD-160 and SHA-256 algorithms, with a network type and a checksum added to it, then encoded with Base58 to make it shorter and prevent typos (Base58 doesn't have similar looking characters like O - 0 and I - l).

Also, somewhere in the middle of the video it is said that all inputs have to be spent entirely in the outputs, but this is not correct as well. You can send less amount than you have in your inputs and the resulting difference between the sum of your inputs and outputs is the transaction fee, that is mentioned later in the video.

These are very minor things though, and overall, this is a very good video, probably the best I've seen covering the technical aspects of Bitcoin.

True, I still need add a note in the video about the public key. As far as I know, this doesn't impact the security of the system, just makes addresses easier to pass around. Also true about the inputs. It's extremely hard to explain Bitcoin piece by piece without telling some fibs along the way!
