0:00 television marketing nonsensical terminology or TMNT for short is an
0:05 acronym that we made up here at lonus Media Group to describe all of the
0:08 overtop terms TV manufacturers use to describe their products refresh rates
0:13 these are usually simple to spot as they mostly consist of an adjective slapped
0:19 onto the word motion such as true motion
0:22 Aqua motion or clear motion but do these
0:25 proprietary rating systems actually deliver the image quality that we want
0:30 for any who might be unfamiliar with what exactly a screen's refresh rate is
0:34 you can watch our video explaining it in depth right up here but basically it's
0:38 the amount of times a screen can update the still images that it strings
0:42 together to create motion in a single second with the standard refresh rate
0:46 being 60 HZ meaning 60 images or 60
0:49 Cycles since most video sources don't exceed that limit demand for faster
0:54 refresh rates has mostly remained among higher grade enthusiasts and
0:57 professionals but recently consumers have been looking for ways to reduce
1:01 image degrading effects such as the motion blur seen in high-speed moving
1:05 images which often is a result from a display's inability to refresh quickly
1:10 enough so how do these high refresh rate Technologies with the funny names try to
1:14 solve this problem not surprisingly they employ different forms of visual
1:18 trickery as you can't exactly extract 120 frames per second out of something
1:23 that was only recorded at 60 or even 30 HZ instead these TVs will fool your eyes
1:28 into thinking that the refesh fresh rate is higher in some way one common
1:32 technique is called backlight strobing which works by doing something slightly
1:36 differently from a normal LCD monitor modern flat panel displays show motion
1:40 by doing something called sample and hold which means it will display a
1:43 static image on screen for a full 160th
1:47 of a second or however long its refresh rate is before loading the next one
1:51 backlight strobing works by only turning on the display's backlight for a
1:55 fraction of a display cycle and instead
1:58 just show a black screen for some portion of that cycle this creates the
2:03 illusion of more frames and therefore smoother motion another tactic is called
2:08 black frame insertion which works uh much the same way except instead of
2:13 turning off the backl the display just shows a black frame other TVs instead
2:18 use motion interpolation which involves a processor inside the display
2:22 generating intermediate frames that are inserted between actual frames from the
2:27 video Source because these generated frames are what the eye might expect to
2:31 see such as a moving car halfway between point A and B this also makes everything
2:37 appear smoother but how well does this actually work if you've ever been in
2:41 front of a TV that can do this stuff it's pretty obvious that things do in
2:44 fact generally look smoother and more flowy than on a more run-of-the-mill set
2:49 whether this is actually a good thing however will greatly depend on who you
2:53 ask the words hyper real and soap oper like have been used to describe this
2:57 effect as while things do look clearer and smoother many people perceive a
3:01 definite fakeness to the resulting motion either because the technology
3:05 isn't perfect or because some people are
3:08 just used to lower frame rates making things look theatrical after all many
3:13 movies are filmed and shown at 24 FPS
3:17 and of course it's important to remember that many TVs that advertise
3:20 refrigerates of 240 HZ 480 HZ or even
3:24 higher often can't actually show nearly that many frames per second rather those
3:28 are numbers that roughly indicate what the manufacturer claims the TV can
3:33 simulate so I wouldn't recommend trying to build a 4 GPU rig and hook it up to a
3:37 so-call 480 HZ television just so you can play TF2 at insan frame rates and
3:42 make sure that you see every single head movement frame and Counter Strike that's
3:47 not going to work but you could try and watch me gesticulate in more buttery
3:51 smooth detail than ever before you
3:55 should use squarespace's 24/7 support
3:58 and live chat or email whatever if you have any troubles with your $8 a month
4:03 website that you got a free domain with cuz you bought it for a year you should
4:07 use things like their responsive design so that your website scales and looks
4:11 great on any device and if you're looking for a job you should probably
4:15 use their cover page module because it looks great if you're trying to sell
4:19 something you should probably use their Commerce module they have modules for
4:23 tons of different things that you could potentially want to use and if you're
4:26 wondering and you're not entirely sure if you want to yet you you should start
4:30 a trial with no credit card required and start building your website today when
4:35 you decide to sign up for Squarespace you should make sure to use offer code
4:39 Linus because you should get 10% off Squarespace you should all right guys I
4:44 hope you liked the video if you liked it like it if you disliked it dislike it
4:47 that's cool too if you guys want us to cover other stuff comment down below
4:51 that would be awesome checko Channel Super Fun we recently did this cool
4:54 thing with like the bubble things and you run around and hit each other and
4:58 play soccer at the same time I don't know it was fun I got to hit people
5:02 whenever I get to hit people I think it's fun to be completely honest does that make me a bad person I don't know
5:06 also uh you know Techquickie subscribe
5:10 that'd be cool see you
