WEBVTT 00:00:00.320 --> 00:00:08.800 It would be a wonderful world if we could just watch everything in glorious 00:00:05.120 --> 00:00:12.160 4K or even at the very least full 1080p 00:00:08.800 --> 00:00:14.400 HD. But we've all been faced with that 00:00:12.160 --> 00:00:20.080 unfortunate choice when watching something that was recorded and encoded 00:00:17.279 --> 00:00:23.600 at a lower resolution. Do you watch it in a tiny little window to keep the 00:00:22.080 --> 00:00:27.920 picture sharp and just kind of move your face closer to the screen? Or do you 00:00:25.760 --> 00:00:33.520 blow it up to full screen only to have everything look like it was recorded on 00:00:30.080 --> 00:00:36.000 a potato? For years now, many companies 00:00:33.520 --> 00:00:41.360 have been looking for a better solution to this, or at least a partial solution 00:00:38.320 --> 00:00:44.079 to this, and it's called upconverting or 00:00:41.360 --> 00:00:50.559 upscaling. And while you mostly see it used as a marketing tool on newer DVD 00:00:46.960 --> 00:00:53.199 players or TVs, you've probably used up 00:00:50.559 --> 00:00:57.920 conversion at some point in your life, even if you've completely sworn off 00:00:55.280 --> 00:01:04.320 optical discs. For example, if you're watching a 480p YouTube video and you 00:01:01.120 --> 00:01:06.320 make it full screen on your HD or full 00:01:04.320 --> 00:01:11.760 HD monitor, then the video has effectively been upscaled to fit the 00:01:08.880 --> 00:01:16.400 screen. You see, that 480p video contains about 00:01:13.479 --> 00:01:23.600 300,000 individual pixels, which might sound like a lot, but full HD resolution 00:01:19.200 --> 00:01:26.640 contains over 2 million pixels with 4K 00:01:23.600 --> 00:01:29.280 being four times that amount. So, there 00:01:26.640 --> 00:01:34.000 just aren't enough pixels then in low res video to actually fit the whole 00:01:31.680 --> 00:01:39.439 screen without doing some kind of a conversion. Now, modern displays 00:01:36.600 --> 00:01:44.320 themselves have logic that can apply an algorithm to a lower resolution video 00:01:41.759 --> 00:01:47.920 clip or even something like your BIOS as you're booting up your computer for the 00:01:45.840 --> 00:01:53.360 first time. And it what it can do is guess what the missing pixels should be 00:01:51.280 --> 00:01:57.680 when it expands the video to full screen. 00:01:54.840 --> 00:02:02.960 Unfortunately, a lot of the time it just plain doesn't look very good. For 00:02:00.479 --> 00:02:09.119 example, if the display recognizes that there's a lot of, you know, grass in 00:02:06.719 --> 00:02:15.360 Sound of Music, it'll fill in that grassy area with basically big chunks of 00:02:12.720 --> 00:02:22.239 gigantic green pixels that looks pretty nasty. Now, upscaling logic can try to 00:02:19.920 --> 00:02:27.920 smooth out the edges of those lines so they don't look so blocky, but this 00:02:24.800 --> 00:02:29.840 amounts to basically an anti-aliasing 00:02:27.920 --> 00:02:34.640 effect as opposed to something that really makes it look as though it were 00:02:31.599 --> 00:02:36.720 actually shot, you know, in 4K, for 00:02:34.640 --> 00:02:41.120 example. So, wait a second then, Lionus. If it's better than nothing, how do I 00:02:38.560 --> 00:02:45.440 get this up conversion then? Can all screens do it? And if all screens can do 00:02:43.440 --> 00:02:50.480 it, well, what's the point of those upconverting DVD players that I see at 00:02:47.840 --> 00:02:55.360 the store? Are they just snake oil? Not exactly. So DVD, it's it's right in the 00:02:52.959 --> 00:03:00.800 name, is a digital format, but most early DVD players only had analog 00:02:58.000 --> 00:03:04.879 outputs like component video. This means that the signal is getting converted 00:03:02.400 --> 00:03:10.080 from digital to analog and then back to digital again when it goes onto your 00:03:07.200 --> 00:03:15.280 flat screen TV. This conversion and recon conversion ultimately leads to a 00:03:11.840 --> 00:03:17.840 loss in quality. So modern upconverting 00:03:15.280 --> 00:03:22.560 players have digital output such as HDMI to avoid doing so many conversions and 00:03:20.239 --> 00:03:27.920 they also have their own more sophisticated upconverting logic that is 00:03:25.200 --> 00:03:34.239 arguably better than especially what an older TV would be able to do on its own. 00:03:30.640 --> 00:03:37.040 Remember though that upscaling isn't a 00:03:34.239 --> 00:03:42.959 real substitute for watching native highdefinition or 4K content and an 00:03:39.680 --> 00:03:45.440 upscaled video is always not going to 00:03:42.959 --> 00:03:51.120 look as good as something that was shot natively and encoded in higher 00:03:48.480 --> 00:03:55.519 definition. So specifically, no matter how good your algorithm is, and they're 00:03:53.040 --> 00:03:59.519 always trying to sell the upconverting capabilities of this new TV when it runs 00:03:58.000 --> 00:04:04.040 at a resolution for which there's no freaking content available. No matter 00:04:01.519 --> 00:04:09.280 how good it is, you can expect some blurriness or other visual artifacts 00:04:06.879 --> 00:04:14.400 from the processor guessing where the pixels should be. But you should notice 00:04:11.519 --> 00:04:19.680 a slight improvement, making it at least a way to breathe a little more life into 00:04:17.040 --> 00:04:23.919 your standard definition videos as long as you manage your expectation and don't 00:04:22.320 --> 00:04:29.040 think that it's going to be as though the Wizard of Oz was shot on a freaking 00:04:26.240 --> 00:04:33.840 Ari Alexa. With that said, if the makers of the Wizard of Oz had asked me if they 00:04:31.040 --> 00:04:39.520 should use an Ari Alexa, I'd have said you should, cuz today's sponsor is 00:04:36.240 --> 00:04:41.759 Squarespace.
