Hey it's me Destin, welcome back to Smarter Every Day. So I'm in a, kind of a strange...
-
Oh! It's a golden play button. That can only mean one thing.
-
Somebody famous. - Not quite famous, I want to say.
-
- So this is mystery guitar man, and if you've checked out YouTube for any amount of time you know who he is.
-
He makes really cool videos and the reason I like your videos is because I think they're smart.
-
- You think so? - I do think they're smart. - Well thank you. - I've always wanted to see one of your smart videos being made
-
so that's what you're doing now? With... this. - Yeah yeah, this is
-
a zoetrope. - A what? - A zoetrope. I can try to take
-
some of these letters, and... ahh! - There we go. [laugh]
-
You have this cylinder, and it has a bunch of animation frames
-
up top. You see right now it's really blurry. They have all these frames which is basically
-
like, you know, like this, like this, like this, like this, like this, right?
-
- Like stop motion right? - Yeah like stop motion basically yeah. When you spin it,
-
the slits act as a shutter so then you get to see
-
little birds flying around. - So why do you need the slits? - You need the slits because
-
otherwise your brain, your eyes are seeing way too many frames
-
and it can't make sense of them. - Ohh.. so basically we're eliminating all the parts
-
that we don't want to see, so you're putting the image in one specific spot, it's like you're
-
indexing it or something. So what does that have to do with a record?
-
This isn't a Neil Diamond record is it? - No no no, it's just a very cheap record,
-
somebody's demo record I guess. Basically,
-
I just spin it like this, and at the
-
speed that it spins, which is as fast as I made it go like this,
-
I have my camera shooting at 23 frames per second.
-
- A very expensive camera right? - It's pretty expensive yeah, it's a good investment.
-
Imagine it spinning very slowly, like this is one frame
-
And then this is the next frame, and then this is the next frame. - So basically it's like aliasing
-
only it's constructive. - Yeah, I like that, constructive aliasing.
-
I think you just invented a new term. So I tried out a really weird frame rate like
-
23.2 frames per second and I can mess with the pitch too.
-
So this specific very cheap USB thing
-
Like if I, I can slow it down, and turn it up, and you can
-
hear in the song actually [very fast music slows down]
-
You can hear... - That's pretty awesome. [music speed varying]
-
- Enough of that, for the copyright. [laugh]
-
- That's pretty sweet. - Yeah so that's how it works basically. - So enough about that,
-
How long did it take to do this? - This is what took the longest. I had to
-
cut out I think 1300 different frames.
-
This bascially is like, you know, just go up and line it up correctly
-
- Are you serious? - Yeah yeah. - So what are these by the way? - These are little frames
-
I would basically paste like this, go to the next one
-
paste it, go to the next one, paste it. And basically these are
-
in sequence all of the frames of the video. And while going, turn the camera on for a second.
-
Done. Turn the camera off. Do this, shut all the lights off.
-
Take all these frames off. Throw them on the floor,
-
and then put the new frames on, turn it on, turn the camera on, turn the lights on
-
- So this is exactly why I like his videos, is because they're
-
awesome but they're brute force. - Brute force yes.
-
- Yeah, that's pretty awesome. - So if the video was three seconds long, I'd say that the video was just
-
from here to here, right, then we
-
would need 72 frames, because I did one frame every second
-
- Gotcha. - Which equals to four full zoetropes, because it's
-
18 times 18 times 18.. [mumble] which is 72 right? - Gotcha.
-
OK so when you made the video, you actually
-
made it one second at a time and then you would reload the entire zoetrope. - Right.
-
Exactly yeah. Not exactly one second, it's a little less than a second because only
-
18 of them fit here, because this is a smaller
-
zoetrope, so I make it 18 24th's of a second
-
whatever that goes down to. - Gotcha. So if you want to see mystery guitarman's video
-
or subscribe to him, like I've been subscribed to you for a long time. - Really? - Like a really
-
like ahh.. guitar impossible? - Oh wow. Really long time.
-
- Long time. - I might owe you a dollar or two then. - Excellent. So go check out his channel
