something that no parent should ever do i missed out on a huge milestone in my son's life he won his first ever gold medal at a competition playing in a badminton tournament and i wasn't able to be there to watch it now in my defense this wasn't actually my fault it was because of the covet 19 pandemic that no spectators were allowed in the gym but that doesn't mean that i accept these limitations so through the power of technology i have decided to equip the badminton center where he trains with a 4k camera and microphone on every court so that i will never miss another game and neither will any of the other parents this is unlike anything that i've ever done before i mean six different streams from six different 4k cameras all coming off one machine and i've got to do it on a budget oh boy and the video is brought to you by ting is a customer-focused mobile provider and they have new rates to help you save more money on your monthly service plan learn more at the end of the video or at the link below the first step in the journey was to find a camera or well cameras because while we could have done this with the same kinds of cinema cameras that we use here at the office like a black magic pocket or something like that it would have been prohibitively expensive and the feature sets of those cameras are designed around making short films or youtube videos and not around broadcast fortunately i came across this the cv 420 cs from marshall who i had never heard of actually because these guys seem to do pretty much no marketing whatsoever the idea appears to be uh if you know who we are then you know it's good and if you don't know who we are you probably don't need it the feature set of this thing is perfect it does up to 4k 60fps HDMI and sdi outputs it's got a cs mount meaning i can use very affordable lenses and how's this for a nice little easter egg a knock to a cooling fan this guy's got good taste what's interesting is that some of the things i would have considered to be a downside for a cinema camera actually work in the cv 420 cs's favor like for example the small sensor a large sensor is great for like an out-of-focus background or cinematic effect but it's not necessarily as good if you want an entire scene to be all in focus like you would for a sporting event also you might have noticed it has no built-in screen whatsoever that saves on cost i picked these up second hand on ebay they seem to be marshall demo units and i got them for just 750 bucks a pop for 4k cameras pretty sweet now let's have a look at this dongle this gives me three and a half millimeter microphone in three and a half millimeter line in locking power connector and oh yeah remote control if i'm into that sort of thing but you don't have to because just look at this it's got a little built-in joystick on the dongle and you can go ahead and configure the camera that way if it's just kind of a set and forget application the final setup behind each court is expected to look a little something like this an inexpensive wall plate and ARM a cs mount lens and then so that you can get some of the action you know like the sound of the racket hitting and all that good stuff we'll put a small microphone like a rode video micro i don't know that i'll go this upscale i might go for something cheaper but this is how it would hook up now let's change gears and talk about our pc obviously if i'm taking in six 4k video streams i can't exactly just throw the cheapest core i3 in it and call it a day but i don't want to spend a fortune on this thing either so what i was looking for was a ton of multi-core muscle but on a budget and first generation threadripper ended up being a pretty good way to go these x399 boards can be found for around 200 bucks these days on ebay and the 1950x which is a 16 core processor can be had for around 400 to 450 us dollars that's a really compelling combo if you're not going to be doing any gaming for example so you don't need really high single core performance as for the rest of the system i've gone pretty tried and true knocked to a u12 s threadripper edition wd blue NVMe SSD some crucial ballistics 3 200 megahertz that i had lying around although i don't know if we're gonna get those kinds of speeds on first gen ryzen two eight terabyte enterprise hard drives that are gonna be running in raid one the last thing we want to do is lose that precious footage a Corsair rm 750 power supply and oh i guess this is kind of where the tried and true business goes away this is fun this is a blackmagic decklink 8k pro this is one of two of these that i will need to take in my six 4k streams so each of these can do up to four these are around 700 us dollars but that is pretty much the only way to go about it also this is something i'm not sure if we're going to need we'll get into this more later but consumer GeForce graphics cards have a limit to how many end bank streams they can handle at a given time it's an artificial limit but it is one that i will have to work around so either we're going to lean on our threadripper to use software encoding or we're going to use a quadro to run end bank encoding on all six streams we'll just have to kind of see how it goes while the plan is obviously to build it in a case eventually and i'm going to use a gt301 from ASUS for now i think what i'll be doing is building it up on the test bench here just in case we have to swap out some of these components for example if i can get away with a much less expensive consumer grade graphics card obviously i would rather do that spoiler alert though for my initial testing i may not be able to downgrade the GPU but rather i may end up upgrading it look six 4k streams it's a lot okay oh confession time i i've already tried this 3200 megahertz didn't work i'm running 29.33 to make sure that our camera feeds aren't cutting out we'll put this RGB on color cycle so it'll be immediately obvious if the image freezes okay neat after some trial and error figuring out what the numbering of the sdi inputs are on this card turns out it goes uh one three two four obviously and remembering that blackmagic deck link cards have a separate configuration utility where you have to tell them i want it to be an input let's not actually configured that way by default the capture card was all set up to the point where it's as simple as yes it worked but there are still some problems problem number one even though these are first-party marshall lenses if i screw them in all the way they are completely unfocused at every possible distance and you see this normally on a c-mount or cs mount lens this is to actually lock the focus or zoom but there is nothing that it locks i can undo it as much as i there's nothing here that turns so i i have something booked with tech support to figure that out for now though i just have to unscrew the lens in order to get it to focus that's not the end of the world and i got another problem i don't know who to blame for this but if i go into the menu 1080p 60. for whatever reason the blackmagic card thinks i'm running in 3d see look at this andy 3d it's not 3d let's do a factory reset there we go because of course we don't want to run 1080p 60 anyway do we we want 4k hey how are we doing now it's a little fish-eye but the reality of it is we don't have that much distance between the back of the court and the wall so i went with a three and a half millimeter which on a sensor this size is what do we say that was about equivalent to like 22. depends on the crop factor there you go whatever the point is yeah it's a little distorted but that's what we're stuck with oh yeah who needs cinema cameras anymore right andy yeah i should just switch to those yeah just switch to these no problem oh here's something i haven't tried yet i didn't have a microphone at home i have no idea what to do with audio here so what was it mike you wanted mike in oh my god i think it's just working ha i am so happy right now sort of so the barrier i ran into when i was testing this is that each 4k stream that i brought into obs whether it was within a single instance or multiple instances of obs would add about 30 GPU usage on my quadro p6000 30 GPU usage that caps me at three 4k streams unless i add a second GPU but what's crazy is watch this i bring in four 4k feeds GPU usage oh this is actually very good news it's not as high as last night well whatever the GPU usage would go to 100 but the fan would barely spin so like a hundred percent of what but it um seems to be just like working great now so that's good oh man we're one percent away from nice GPU usage on our 420 cameras i made it this far without without commenting about it i'm pretty proud of myself hey there it is nice this is sick and they're all like working right sweet for encoding settings in a perfect world i want to be using NVIDIA nvenk on all six of the streams so that the CPU is basically not touched but i want to have enough CPU grunt so that i could use CPU encoding as a troubleshooting step if i really needed to i'm running at 5500 kilobit per second which is pretty good for 1080p60 on twitch and then as for where we're actually going to stream uh i message twitch because i'm a partner so i can message them to ask if i'm actually allowed to create like you know five or six twitch channels and like stream concurrently to them all i don't know if you're really allowed to do that so worst case scenario we'll try and get something set up with youtube and then as a fallback i'll be like hey luke do you want to put in some engineering time and we can just do this on Floatplane let's start recording these are all just going to the local SSD for now i haven't actually hooked up the hard drives but we can do that in a little bit and coding overloaded oh boy that happened pretty much immediately there goes the GPU usage okay then second quadro time we all knew this was gonna happen while we're at it i don't have my other quad sdi capture card so i'm gonna throw this deck link mini monitor 4k in here and see if we can use that to at least get a fifth one going here to attempt to solve this problem i'm following the steps epos vox suggested for installing a portable version of obs so basically you just throw a portable underscore mode.txt file in some directory other than program files that you have unzipped the application to then you go into the global config file and add video adapter idx equals one so remember that one is two because zero is one we're gonna go ahead and save that and my fourth feed should be coming off my second GPU why is the fan not spinning on this quadro also i don't see uh it's not picked up at all what the crap is this quadro dead son of a so start recording start recording start recording all three of those should survive running on the gp 100 so that's the higher performance one and i had to throw a lesser quadro in there because my other one's broken now let's see what happens if we start recording on that one i think we're good and there's more good news the video and code usage on the p2000 is only 29 so if i didn't have a p6000 or excuse me gp100 lying around then i could definitely use lower end quadros i wonder if i could get away with g-force i'd have to put like three g-force cards in and have each of them do two it seems like it's getting even clutter adam also mentioned that one of the things that helps with a configuration like this is actually taking those obs instances that you want running on a separate GPU plugging a monitor into that GPU and like moving the window over to that monitor just to make sure that they stay stuck where they're supposed to go so all that's left now is to plug in one more sdi because that's all the inputs that we have and see if we can get five going okay oh to get the fifth camera working we're gonna have to acknowledge one other thing that i uh bunged up as part of this process i don't know a lot about c and cs mount cameras and lenses so i figured oh well you know rather than just getting all these sort of cheapo marshall ones no offense marshall uh i'll go on ebay and i'll see if there's any better lenses available oh tokina oh they make good stuff i'll just get a tequila lens uh so i picked up this puppy it's a zoom it's really affordable feels good only one small problem looks fine right looks beautiful when i have it at maximum zoom and then watch this oh no never seen a vignette that bad so it's designed for a sensor that's actually even smaller than the one that i have so um i'm just gonna have to get a couple more of the marshall first party ones because i don't feel like digging through all the compatibility documentation of which there's basically none to find which you know third-party lens is going to work on this thing of course needing to exchange a lens doesn't prevent me from validating my solution here i've got five feeds four of which are still recording without dropping frames so all i've got to do is start recording on one more and see what happens so the quadro gp100 is at 80 usage and the p2000 is at 40 usage or so and we're looking good i can play around a little bit with my GPU configs but i think i have a streaming setup this is five different angles of my i have a streaming setup dance oh yeah oh yeah streaming setup guys now all that remains is to set it up at the badminton center and see how it works tang mobile has new rates that make it easier to see how much you're saving when you switch they've got unlimited talk and text for ten dollars data plans that start at fifteen dollars with unlimited data for forty five
