1 00:00:00,320 --> 00:00:08,800 It would be a wonderful world if we could just watch everything in glorious 2 00:00:05,120 --> 00:00:12,160 4K or even at the very least full 1080p 3 00:00:08,800 --> 00:00:14,400 HD. But we've all been faced with that 4 00:00:12,160 --> 00:00:20,080 unfortunate choice when watching something that was recorded and encoded 5 00:00:17,279 --> 00:00:23,600 at a lower resolution. Do you watch it in a tiny little window to keep the 6 00:00:22,080 --> 00:00:27,920 picture sharp and just kind of move your face closer to the screen? Or do you 7 00:00:25,760 --> 00:00:33,520 blow it up to full screen only to have everything look like it was recorded on 8 00:00:30,080 --> 00:00:36,000 a potato? For years now, many companies 9 00:00:33,520 --> 00:00:41,360 have been looking for a better solution to this, or at least a partial solution 10 00:00:38,320 --> 00:00:44,079 to this, and it's called upconverting or 11 00:00:41,360 --> 00:00:50,559 upscaling. And while you mostly see it used as a marketing tool on newer DVD 12 00:00:46,960 --> 00:00:53,199 players or TVs, you've probably used up 13 00:00:50,559 --> 00:00:57,920 conversion at some point in your life, even if you've completely sworn off 14 00:00:55,280 --> 00:01:04,320 optical discs. For example, if you're watching a 480p YouTube video and you 15 00:01:01,120 --> 00:01:06,320 make it full screen on your HD or full 16 00:01:04,320 --> 00:01:11,760 HD monitor, then the video has effectively been upscaled to fit the 17 00:01:08,880 --> 00:01:16,400 screen. You see, that 480p video contains about 18 00:01:13,479 --> 00:01:23,600 300,000 individual pixels, which might sound like a lot, but full HD resolution 19 00:01:19,200 --> 00:01:26,640 contains over 2 million pixels with 4K 20 00:01:23,600 --> 00:01:29,280 being four times that amount. So, there 21 00:01:26,640 --> 00:01:34,000 just aren't enough pixels then in low res video to actually fit the whole 22 00:01:31,680 --> 00:01:39,439 screen without doing some kind of a conversion. Now, modern displays 23 00:01:36,600 --> 00:01:44,320 themselves have logic that can apply an algorithm to a lower resolution video 24 00:01:41,759 --> 00:01:47,920 clip or even something like your BIOS as you're booting up your computer for the 25 00:01:45,840 --> 00:01:53,360 first time. And it what it can do is guess what the missing pixels should be 26 00:01:51,280 --> 00:01:57,680 when it expands the video to full screen. 27 00:01:54,840 --> 00:02:02,960 Unfortunately, a lot of the time it just plain doesn't look very good. For 28 00:02:00,479 --> 00:02:09,119 example, if the display recognizes that there's a lot of, you know, grass in 29 00:02:06,719 --> 00:02:15,360 Sound of Music, it'll fill in that grassy area with basically big chunks of 30 00:02:12,720 --> 00:02:22,239 gigantic green pixels that looks pretty nasty. Now, upscaling logic can try to 31 00:02:19,920 --> 00:02:27,920 smooth out the edges of those lines so they don't look so blocky, but this 32 00:02:24,800 --> 00:02:29,840 amounts to basically an anti-aliasing 33 00:02:27,920 --> 00:02:34,640 effect as opposed to something that really makes it look as though it were 34 00:02:31,599 --> 00:02:36,720 actually shot, you know, in 4K, for 35 00:02:34,640 --> 00:02:41,120 example. So, wait a second then, Lionus. If it's better than nothing, how do I 36 00:02:38,560 --> 00:02:45,440 get this up conversion then? Can all screens do it? And if all screens can do 37 00:02:43,440 --> 00:02:50,480 it, well, what's the point of those upconverting DVD players that I see at 38 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 39 00:02:52,959 --> 00:03:00,800 name, is a digital format, but most early DVD players only had analog 40 00:02:58,000 --> 00:03:04,879 outputs like component video. This means that the signal is getting converted 41 00:03:02,400 --> 00:03:10,080 from digital to analog and then back to digital again when it goes onto your 42 00:03:07,200 --> 00:03:15,280 flat screen TV. This conversion and recon conversion ultimately leads to a 43 00:03:11,840 --> 00:03:17,840 loss in quality. So modern upconverting 44 00:03:15,280 --> 00:03:22,560 players have digital output such as HDMI to avoid doing so many conversions and 45 00:03:20,239 --> 00:03:27,920 they also have their own more sophisticated upconverting logic that is 46 00:03:25,200 --> 00:03:34,239 arguably better than especially what an older TV would be able to do on its own. 47 00:03:30,640 --> 00:03:37,040 Remember though that upscaling isn't a 48 00:03:34,239 --> 00:03:42,959 real substitute for watching native highdefinition or 4K content and an 49 00:03:39,680 --> 00:03:45,440 upscaled video is always not going to 50 00:03:42,959 --> 00:03:51,120 look as good as something that was shot natively and encoded in higher 51 00:03:48,480 --> 00:03:55,519 definition. So specifically, no matter how good your algorithm is, and they're 52 00:03:53,040 --> 00:03:59,519 always trying to sell the upconverting capabilities of this new TV when it runs 53 00:03:58,000 --> 00:04:04,040 at a resolution for which there's no freaking content available. No matter 54 00:04:01,519 --> 00:04:09,280 how good it is, you can expect some blurriness or other visual artifacts 55 00:04:06,879 --> 00:04:14,400 from the processor guessing where the pixels should be. But you should notice 56 00:04:11,519 --> 00:04:19,680 a slight improvement, making it at least a way to breathe a little more life into 57 00:04:17,040 --> 00:04:23,919 your standard definition videos as long as you manage your expectation and don't 58 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 59 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 60 00:04:31,040 --> 00:04:39,520 should use an Ari Alexa, I'd have said you should, cuz today's sponsor is 61 00:04:36,240 --> 00:04:41,759 Squarespace.
