Raspberry Pi 5: Video Editing, Video Calling & Passive Cooling

[Music] welcome to another video from explaining computers.com this time we're going to run some more tests on a raspy Pi 5 firstly we're going to try out video editing in Caden live and indeed this whole video is being edited on a raspby pi 5 secondly we're going to try to make a video call which really needs to work if you want to use a raspber pi 5 as a small desktop PC and I know a lot of people are interested in that and finally because I've had a lot of requests I'm going to try some experiments with passive cooling so let's go and get started right here we are back on the raspy Pi 5 and as you can see we're running with an SSD connected to one of its usb3 ports with both rasp pios and our video files on this drive which will give us the best performance for video editing and in the future we'll be able to use an m.2 mvme drive connected to the pi 5's PCI connector over on my desktop here we are I've installed Caden live and I did this in a terminal using the command Pudo app install Caden live so if we go to the menu over here you'll find that under sound of video you can see Caden live there it is we'll run it up and here it is coming up on the pi five nice and fast control shift F just brings us full screen and I now go to our sample edit which is sitting down there the sample edit I use on lots of different sbcs and testing you'll see we got a bit of a problem because in the project montra up here we can just see green which is clearly not what these clips are actually of so there's a problem here and we therefore come out of Caden live like that and you might be wondering what is going on well the issue is that the pi 5 only runs the latest version of rasby Pi OS and this is based on Debian 12 or Bookworm and launches in mid October 2023 and this Debian 12 version of raspy Pi OS uses whand rather than the older xorg for its display server and this does cause problems for some existing applications including Caden live as we just saw but do not fear as I reached out to raspy Pi who came up with a solution of running Caden live using X whand which is an emulation layer to provide compatibility for applications that currently work properly with XR and if we bring up a terminal like that this is the command we need to execute so uh let's do just that here we go Caden live is coming up again very exciting there it is control shift F and if we go back to our sample edit which is sitting uh still there and oh look we've got a picture we can see ducks and stuff and this works very very well indeed let's just play this edit you can see normal playback is absolutely fine we we would kind of expect that it was on a pi4 but when we get to the dissolve we get to the transition it's beautifully smooth this is better than I've seen on any arm-based single board computer with the exception of the orange Pi 5 which works just as well as far as I can see anyway as the the raspby pii so that's pretty good and you might be thinking you don't want to launch Caden live from a terminal over time so let's just come out of this like that and quit there we are and close down the terminal and you might have noticed I put myself an icon on the desktop so I can just uh run up the file and execute it like that and it'll run up Caden live just as we just did there we go and if we just go back to our test edit because we've got more business with it because I'm sure you want to know how long it'll take to render out this test we've done it before in many other single board computers so let's just go to project and render where I've got set up the script for the render and let's just remind ourselves how long it did take on some other computers where a pi 4 took 2 minutes and 19 seconds an orange Pi 5 52 seconds and a bmax B1 plus x86 Mini PC to 1 minute and 45 seconds so let's try this on the raspy Pi 5 we start the script but uh it'll take a second or two so we will speed on through and here we are it's finished finished in 2 minutes and 8 seconds I'm surprised at that it is a better school than a rasid pi 4 but clearly not much better the performance on the timeline here in Caden live on a raspby pi 5 is massively better than on a raspby pi for but that render time well all I can do is show the results that uh that come up and that's the result we've just got maybe running Caden live using the the fudge for xorg and xway then maybe that's affecting performance I don't know anyway that is how Caden live is performing at the moment and the other thing I want to do here is to show you the other important edit which is of course the edit for this particular video if I can actually bring that up looks like I can and let's just uh use the whole area to see the edit and uh this is the video you're currently watching at least the start of it it finishes here right now but I'll be adding to it obviously with this bit oh it's very confusing isn't it and I would point out that the actual composite for the opening shot here I did do this in Adobe After Effects I'm only here using Caden live and a Raspberry Pi 5 to replace Premier Pro in the production of this video not all of my video tools but uh it is working perfectly well and oh I should also point out I'm using proxies in Caden live as I always do on the lower-end hardware if we look at proxy Clips here they are enabled as you can see and uh we should just of course check this is actually working let's just show you a bit playing welcome to another video from explaining computers.com yes it's working I have no doubt I can complete my mission and edit this video here on a rasp Pi 5 so let's now move on to another test right we're now going to try video calling on a raspby pi 5 and I've arranged to have a call with Kevin who runs this YouTube channel here all about robots and also single board computers and all that kind of stuff and in fact Kevin made a lot of content around the launch of the raspby pi 5 as you can see including the interview with AB Upton and an interview with myself so let's go across to uh Ms teams where I've got a call setup with Kevin down there as you can see I'll just click on that and join the call like that and let's just give ourselves a bit more space on the screen f11 and as you can see here I am hello and I'm currently on a camera which is connected to the pi via USB it's actually a camcorder but it is appearing to the pi as if it's a webcam I'm simply using a Camcorder for various technical reasons in terms of being able to record the audio and things separately in terms of making a video but as far as the Pi's concerned it's just got a webcam connected for holding a a video call and if you're wondering how am I wearing headphones phones the answer is the headphones are plugged into my monitor they can't be plugged into the pie because it hasn't got a 3.5 mm audio jack so what should happen in a few minutes time is that Kevin will call in in fact I should join first shouldn't I I'm going to go into the meeting I should know how this works I live my life in Ms teams but there we are and uh here it is oh look it's me on the screen so as I was saying in a few minutes time Kevin should be calling in and Microsoft will stop giving us lots of messages so Let's uh speed forward in [Music] time and here we are back again I'm just going to record and transcribe this call so that is a good and admit Kevin let's see what happens and things are happening Kevin can you hear me hello hi there Chris can you hear me I can hear you can you hear me okay I can hear you okay as well we are holding a video call on the rasp Pi 5 wow and um according to Microsoft I should let you know I'm recording this call you probably knew that anyway and welcome welcome to the channel you know you're only the second person to be on the channel other than me and the first one was Ean Upton who I I know you interviewed recently wow I'm very honored Chris thank you for having me on that's um we we seem to have a slight lag actually it's not absolutely perfect it's um maybe the pi is struggling a little that's probably my wi let me connect to cable and see if that improves things let's see it might not be the P it might be the other end so um let's try the wire yes I don't think it's the P I think yes we we wer BL the pie but um so as I said you right I'm now connected by a wire hope that'll be a bit a stronger connection do Jun know I don't know which was got more wires either end we're both surrounded by by wires as I say and you talked to Evan before the pie came out didn't you that was must been an interesting day it was a very interesting day yeah I've traveled down the day before that's quite a journey from where I live up north to uh to Cambridge all right um so I sort of stayed overnight and then uh went to pie Towers at first thing in the morning so yes it was a very exciting day set up all the cameras all the equipment wanted to make sure I got plenty of different angles and then uh had about it with my questions fantastic I'll I'll drop a link to that in the in the video description and there'll probably be a card somewhere around on the screen as we can do as well and this wonderful thing called YouTube but it seems to be this works doesn't it as far from my experience here this is just a normal a normal call yes it's a very very smooth video very very crisp there seems to be very high quality as well there's absolutely no lag of the image um so yeah and I'm running on the rasby pi 5 as well if I just tilt my camera down here you can see on the desk I have Myas P just here so we're working pie to pie you can't say more than that can you I think we have therefore proved categorically it is possible to do that all of those really important things for if you're going to use a p a desktop computer hold a video call Fantastic yeah well in that case thanks for the call I'm sure we'll keep in touch as we do on all things pi and uh I'm now going to sign off to you now and just show the audience watching this um the recording I've made to see if that's worked as well but I imagine it has but thanks for joining us here on explaining computers thanks Chris bye for now bye and there we are and if I just go to the right place I should be able to find my recording of that call and here we are I found the file so we can just play this along and uh this is what Ms teams recorded and things are happening Kevin hello hi there Chris can you hear me I can hear you can you hear me okay I can hear you okay as well we are holding a video call on the rasby pi 5 and uh there we are I will say no more I think we've had a very successful test greetings shall we turn our attention to Cooling and here our rasp Pi 5 is using one of the two official cooling solutions one of which is the official case which is fitted with a fan like this and comes with a heat sink and then the other solution as we're looking at right here is the heat sink with the fan mounted on it and I would point out that this is the best 30 mm fan I've ever tested on an SBC it's properly temperature controlled it doesn't just go on and off as they do on some sbcs it's speed controll by the pi so if you're worrying about a pi having a fan and being noisy don't don't worry about that the official fan is very good indeed this said lots of people have asked me about potentially passively cooling Aras Pi 5 and so I'm going to run three tests first of all we will test the pi with the fan and the heat SN to get a Baseline and then secondly I'll just disconnect the fan and we'll test the pie with just the heat sink without the fan running and if you're wondering could we use a pi5 without any cooling solution at all the answer is no I've seen one test of that the pie will throttle after about a minute so I'm not going to try that test I'm only going to test just with this particular heat sink without the fan and then for our third test I'm sure some of us can imagine a situation where the pie has got a large passive cool or a large heating on it and you think back to some of the spcs I've looked at in the past here's a nanop pi 4 which has a massive cooler connected to it where the S so here is on the base of the board and I've several times on the channel brought in Mya raspby Pi 4 in this heat sink case the base of this is really just to look nice but on top of it here this is a very large heat sink which passively cools a pie I really like this type of case and it's not difficult to imagine this type of case but designed for a rasp Pi 5 it would be slightly difficult because of course there's lots of connectors more on the pi five and the pi4 they have to work around but something with a lot of metal maybe a bit higher going across the port or something that could well work and I can't just fit this onto a pi5 because the lugs on the bottom of this wouldn't be in the right positions but what I can do is to bring in these heat sinks which I've used before on a pi 3 and a pi4 this one's even got a little copper shim on the base so I've got various bits of metal available which will allow me to Mount one of these hopefully this one the bigger one on the pi five so that will be our third test anyway let's start out with the the heat sink and fan combination so let's go across to the desktop and here in Genie I've written this little Bash script quite similar to ones I've used many times before on raspber pi 3es and fours and what this basically does is to clear the screen and then to start a loop which will run for 10 cycles and inside this loop it's going to take a temperature measurement and then it's going to run a CIS bench command which will Factor prime numbers to a maximum of 50,000 but constrained to a time limit of 120 seconds 2 minutes and also it's got its output suppressed so the only thing we'll see on the screen here is the temperature measurement so this will go on for the 10 cycles and then finally we'll take a final temperature measurement so we're going to end up with 11 temperature measurements on the screen 2 minutes between each for our 20 minute test so let's close this down and go to the terminal and execute the script we're starting with an idle of 41.1 De but let's now speed on through our 20 minute test and there we are with the uh smell of warm Electronics in the air our Baseline test is complete and the stock fan and heat sink have clearly done their job very well the pie is not throttled which will be at about 80 plus de it's stabilized at about what 57 58° and if we look across to the pi we can see that its fan is now spinning it's been doing so since about the first minute and it's doing so completely silently but uh regardless let's now move on to test passive Cooling and by the magic of film making here we are the p is now running again with its fan disconnected so let's go across to the desktop where I've let things cool down the pi is now ID Leal long as it was at the start of the last test at about the same temperature which is not surprising because the fan wasn't spinning at the start of the last test so it's effectively identical so far and uh let's run the test again and see what results we get so there we go this is our first test of passive Cooling and there we we are it is finished the pie I'm sure is relieved about that and we have managed to stay below the throttling temperature running at about to 15° higher than we were with the um fan and of course we don't know how far it go if it won't Beyond 20 minutes but this isn't a bad result although do remember we not got a case on the P here and if we go across to the P itself I would point out if I try to touch the heat sink I can barely do it it really is very I would describe as dangerously hot so let's move on to see if we can test out a better passive cooling solution and here we are with the p equipped with the large heat sink I showed you earlier this is a put on using thermal tape I've been very careful not to short things out but I would absolutely not recommend you try this unless you're being very very careful this is simply a test to see to what extent we can get a better passive cooling result but uh with that said let's go across to the desktop here we are and you'll see our idle if you just look at the top corner here it's only about 2728 this has been running quite a while more than it ran for the previous test so the heat sink so far is doing okay so anyway Let's uh press enter and uh speed on through for our third set of test results and there we are what a result only slightly warmer at the end of the test than we saw with the official cooler with its fan and in fact we might even have been approaching a point of stability who knows but uh regardless there must be fantastic potential here for third party manufacturers to make passive coolers for the raspby P 5 and let's put all of our results on a table like this great to see clearly a good result for the custom heat sink and I'd forgotten how much I enjoy doing Raspberry Pi temperature tests the rasby pi began its life as an educational tool that soon found application in many maker and Industrial projects but today the raspber pi 5 is an rsbc that can also be used for mainstream desktop Computing talking of which the edit for this video is now nearing completion in Caden live on the pi five and based on tests I've done so far I think it'll render out in just under an hour I obviously can't tell you exactly how long this video will take to render because I'm still shooting this video but I will put that information in the video description in case you're interested but now that's it for another video if
