How a 3D TV works in Super Slow Motion - The Slow Mo Guys
3D glasses are surprisingly fast! Gav whacks out the phantom to show you how on earth a Plasma 3D TV and glasses complete the rather complex task of showing 3D content on a 2D screen. Check out for 50% off your first month on any crate.

    lets make neutron star collisions simulation make 2 Neodymium Magnets covered in ferro liquid with same size and weight separately then make them collide in spiral way you can make them collide using trampoline-like medium that will draw everything heavy to its center or by hanging them with string then swing it till they meet each other in the center the fun-things happen in last seconds until they collide when each magnet pull others ferro liquid and when they collide they will splash ferro liquid in unique way

    I'm not exactly fussed that the tech was abandoned. 3D has always kind of annoyed me. It somehow cheapens the film for me and I genuinely enjoy them less as a result

    A video idea but Caution! Try hitting a puddle of nitroglycerin with a remotely triggered spring loaded hammer at a bomb range and film it at a ridiculous frame rate. You're in for a shocking surprise .😏

    hi gav, have you ever recorded a safety barrier in slow motion before? i saw one on youtube that could destroy a 60mph truck based on its design, that can only be seen working in slow motion. at the speeds you use, you would capture every individual hit against a trucks front upon impact.

    there's nothing special about 3D screens. 3D TVs are 100hz instead of 60hz. NVIDIAs active shutter technology, "NVIDIA 3d vision" requires monitor with at least 120hz refresh rate, which most of us gamers have anyway. In-fact 120hz never caught on, so most high refresh rate monitors have 144hz or faster displays.

    Yeah, and the saddest thing is, they did stop 3D when it was going to get real fun with OLED, 4k, HDR and HFR... With today's 8k panels, HDMI2.1 and LG's passive technology things would be great.

    I've got a 2011 Era Samsung 3D LED TV with active glasses,, and it's pretty cool. I don't watch much 3D stuff anymore as like you said they have pretty much abandoned the tech but the few movies I do have are super cool tocwatch still!

    You can also cross your eyes and get the image to focus with the side by side videos.

  • tensago

    I was 10 years old, it was 1993. Nobody reading this would probably believe this but I myself came up with the idea of using liquid crystal glasses to filter two separate video streams into the eyes using a time controlled system. Initially the purpose was to enable two people in the same room to watch two separate programs on a single screen by wearing a pair of these glasses which would filter the correct frame from the correct show to the person who wanted it and each wearing headphones so they could hear the show they wanted.
