NASA Has Some Smashing Video Which Screams Green Screen

You know NASA offers free resources but maybe you don't know the quality of them.   These are 1080p at 1920 x 1080 resolution.  Highly excellent quality and perfect for my videos.  I have just downloaded a flyover of Ceres, a planet, asteroid, wandering rock, and also a NASA physics spectacular with lots more of the ultra kozmik.

(Ed:  nerd joy for you but so what?)

We don't care what they are, Barney.  We just like the appearance.  It's a trip flyin' over an asteroid like it's going to Puerto Vallarta.

(Ed:  ever been there?)

Nope.


There are often references to 'layers' in video so think of the flyover of a crater as the lowest layer.

Maybe I'll add a layer of video featuring butterflies flying about.  Ordinarily that layer would obscure the lowest layer but we will make this one, say, 50% transparent.  Now we can see both and it's getting surreal.

It's a bit dizzy-making to fly around the crater in the spaceship.  If the butterflies fly at random or in the other direction, it will either stabilize that or make you puke your guts up from disorientation.  Tough to tell without trying it.

Transparency only works for a few layers or the overall view just turns to colorful goo and the other way to add layers is with a green screen.  This is turning into a major lust because I'm fairly sure it's possible to acquire one even if a bit of a struggle to do it.

With a green screen, I can put myself on the Moon if I like.  That's no great feat of technological wizardry since I learned the spell and it works.


There's another spell I learned a minute ago and that's a low-cost green screen on eBay is $30 to $40 and that's 10 feet x 13 feet which is a near-perfect match for the back of the room.  There's no move on this since it will take a truss to support the thing and it's too expensive to get a light rack but it doesn't need to support that much weight anyway.  The trust only needs to be a thirteen-foot bar which will be where the green screen sheet is clamped.

(Ed:  why bother?)

Stand back, Gladstone.  You definitely need yer groove glasses for this because it doesn't matter that I can be anywhere but rather this brings a virtuality to the existing surreallism of the Rockhouse and that makes all-out lost in space.  The only thing to disappear with a green screen, so long as it's good quality and I don't bork the shoot, will be the back wall of the Rockhouse.  The green laser beams will probably get wounded but that's variable depending on the quality of the dyeing to match the chroma key for the screen (it's a muslin sheet).

Whatever is in the back wall can change during the course of a video, it could change every frame if you like but there would be no point in doing that.


Think of it for yourself.  There's the lowest layer mentioned up top which shows what it looks like to fly over a gigantic crater on Ceres.  Over the top of that goes Silas with some whackjob musician-like stuff and that layer drops over the Ceres layer.  Because of the green screen, you can see through the Silas layer to the Ceres layer.

(Ed:  why?)

Because I can (larfs).


It's unclear what story plays.  Does it go ... there I was playing my guitar as the spaceship flew over the crater on the asteroid.  That's not sci-fi, that's crap ... but it would look cool.

(Ed:  that's your same bitch with sci-fi cartoon movies)

Yah, well ... for me it's ok, right?

(Ed:  pfft.  I will be watching Walter Herzog at Sundance to see his movie about Artificial Intelligence.  You just keep on trying to develop any kind of intelligence.)

By the grace of the Great God Mescalito, God of All Trippin' People, it shall be so.

(Ed:  what the hell does that mean?)

No idea.  I just like how it sounds.

(Ed:  kind of like playing a guitar while flying over asteroids in a spaceship?)

Something like that.
