"WEBVTTKind: captionsLanguage: enSo you want me to record 15 milliseconds(15,000, 1,500, how many? ) Yeah, 15 (That makes 15)1000. 15,000 is 15 seconds. (Okay, go on then)RightThere we are. Is this thing on?Hello and welcome to ComputerphileI think that looks pretty good here.(I kind of wanted a bit of advice because I've bought this Raspberry Pi 4, and it seemed pretty powerful)(So I thought, why not try and make a video on it?)(I just want to see if I can)(If it could do video editing, right?)Ok, so presumably you want me to put it together?(Yeah go on then)Ok, I bought one of these too when they came out there. They are incredibly powerful machines for what they are.We've now got a quad-coreCPU and again, it's been upgraded from beforeThe RAM is now separateWe've got 4 GB of RAM on here instead of one GBThe thing that interested me most is Gigabit EthernetUSB 3, which means we've got pretty decent connectivity off this and get 5 gigabits per secondI think off here one gigabit a second off that, got some USB 2 ports for things like keyboard and so on so it's greatwell, I meanI think lots of interesting things you can do. We did some interesting things the other week with the Raspberry Pi 3It's got the potential we're feeding, we definitely know we can feed 30 megabits per second video to these thingsAnd they can cope so you've got, you've got enough - a chance with this. So let's get it up and running for youWhat else have we got here? I see you've been off shopping at Pimoroni(To be fair and even-handed some of that stuff came from The Pi Hut as well.)Okay, so other Pi shops are available. So what have we got? We've got heat sinks, these things do get warm. So they're quite goodbut we also haveThe Pi fan as well. Let's start with that. Let's start with the fan and put the heat sinks on as wellif we need to because it works better andwe've got a cameraand a power supply. Let's move over to the other desk and we'll start building this. We've also got a battery powersource and a monitor over here. Yes, but let's actually see if it works first before we start building thingsDodgy old keyboard and mouse here fromGoodness knows when. So we've got a NOOBSSD card in thereOne thing you have forgotten to give me(go on)batteries(batteries?)Power, yepSo be interesting to know how long we could power this off a battery to, umSee if we could film with it. So the other nice thing we've got dualHDMI, I think that's HDMI zero so that's going to there, so that hopefullyShould now boot.See what we've got. It's doing something, the lights have come on, let's turn the monitor onWoohoo1080p60Looking good so farAnd it's booting into RaspbianResizing the file system, rebooting in five seconds. So it's all workingI always use them from the command line. So I'm never used to theThingsSo hopefully that will shut down, there we are, that looks like it shutdownSo let's put this togetherNow sure, and we'll now edit this as a nice montage with some music*Nice Music*One thing I tend to do when building these things is put the screws in upside down to start with because that wayIt holds things together as you sort of stack things*More nice music*(So why is there a right way and a wrong way?)I don't know, I just think the pointy bits work better as feet than the non-pointy bitsSo there we have a thing built. The other thing we do is put the fan shim on just to keep it nice and coolThese things run fine without it, but they do start to throttle, if you're going to be video editing on itIt might get a littleover-warmSo what we end up in this package is fan from there, a little control boardWhich the fan screws intoAnd that one'll pop on once it's assembled. So you should attach the fan to this first(This is an elaborate ruse to get you to build it for me Steve)I'm getting that impressionSeveral hours later. We got theThing in and now this just clips over the GPIO pin so you can still use themLike that, and now it'll now blow nice cold airontoThe system for us. But you've got me another toy as well, haven't you, Sean?You've got another toy which is a cogSome more that I think it's the camera moduleNow the one thing I found with these cameras is that they do not like being touchedThis seems to be some sort of focus control. So we'll pull that, now this is now right in the waySo we'll take that offSo you just pop that in thereThat looks like it's in place, we've now got the cameraAttached. Can pop this furnishing back onMaking sure to get it accurately lined up over the pins. Quite a clever designWe going to shoot it on this camera as well? (Let's see what we can achieve) All right.(So that colored screen, that's the POST, is it?) YeahYeah, the bootloader displays out on the GPU and then it loads the kernel off the SD card and eventually the kernel starts upAnd we're into NOOBS. So I think I need to configure theCamera first so the fans running, it's blowing air down. (Nice and quiet. That's good.) Yep. We could find out howCold the CPU is, measure tempThirty nine point zero degrees. So we're going to turn on the interfacing options. We want the cameraEnabled, yesCamera enabled. ExcellentWould you like to reboot now? YesSo if we do \"raspivid -f\"There we are. Of course the cameras upside down (whoah)(So you're going through looking at the options and just appending them to a) Command line\"-r test.mp4\"So there we have it there Sean. So it's working, you just need to work how to record with itStopping us loading a different program's coding data again from storage into memory as wellAnd then we can start that program instead. kind of invertible and that's something statistically weakerBut if you didn't do that, right?So there's a rules you should be careful about when you're designing these kind of things\n"
