This Video Is 2D And 3D Simultaneously: the Pulfrich Effect

Hold on tight, because with a stabilised camera shot and a pair of sunglasses, you're about to see a video that works in both 2D and 3D at the same time. The technique's called the Pulfrich Effect, and this is how it works.

I lost my sunglasses in a lake this summer...

Didn’t realise I’d lost a whole dimension

“If you’re holding your phone in bed you look ridiculous”

Says the guy who is literally spinning around in a park

[MaskedDeath_]

I'm a damn moron. After being amazed that this actually works, I tried to check if it'd work in real life. Took me a moment to realize real life is 3d. Dammit.

the "like this video" in "gimmicks like this video" (about 3:14 -ish) made youtube highlight the like button. amazing.

"if you're kinda just lying in bed, squinting, holding your phone out, it probably won't work. oh and also, you look ridiculous"

i suddenly feel attacked

This dude and his excitement for doing the videos in "ONE

[vadrif-draco]

Expectation: "This video is 2D and 3D simultaneously"
Reality: "This video is 720p and 144p simultaneously"

For a solid 5 min I was putting the sunglasses on normally, covering my right eye with my hand, and wondering how this could possibly achieve a 3D effect

[quahntasy]

Just when you need your sun glasses and they can't be found any where.

[fernclio]

to anyone else who just searched their entire room to find sunglasses for a 3 minute video, I feel you

[Niei]

There was an animated series in the 70s which used this effect and a breakfast cereal company was giving away glasses to watch it.
I recall using those glasses on different TV shows and when I happened to watch something filmed inside a train and the moving background through the window looked amazingly 3D!

Most YouTubers can't say a single sentence without doing multiple takes and using jump cuts. Tom Scott: ONE TAKE!

“If you’re just kinda lying in bed holding your phone out squinting it probably won’t work.”

Well, I guess this is going in the “Watch later” playlist...

"You'll need a pair of sunglasses."

*looks around*

Damnit.

[BjornsonVideos]

I have the worst vision in the world. There is no eye prescription that can help me. But I am very grateful to see the little vision I do have. Thanks Tom for recognizing that not all your viewers can see. That made my day for some reason

[lannew]

"Also, uh, you'd look ridiculous..."
me in my room with 6 lights on and wearing sunglasses over my regular glasses: *psh, would hate to be THAT guy*

[krissyai]

one of the most wholesome things that exist is tom's happiness after doing the shot in one take

[clarahowson]

‘Also, you look ridiculous’

It also looks ridiculous when you have to run around in circles in the middle of a public park trying to film a video. No I’m not bitter.

[omniummysterio]

I love how Tom celebrates after getting it in one shot (and does it for other vids, too).

[JediMaestr]

0:13 I appreciate Tom taking the time to think of me and apologize. As someone who is blind in one eye, I feel seen by both of Tom’s working eyes
