Multi-Camera Live Stream with the ATEM Mini

in this video I'm gonna show you how to set up a multi-camera shoot with your Blackmagic designs a 10 mini hello I'm Stephen ballast welcome to my channel where I explore worship technology solutions this is part three and a multi-part series about the new a-10 mini in previous videos I've showed you how to get your a 10-minute configured and streaming to Facebook live using OBS in my second video I talked about audio and went over some of the nice features that the mini has for audio in the next video in this series I'll talk about how to bring your lyrics in from a projection computer and overlay that over your video so if you haven't already be sure and subscribe to my channel so you don't miss that in this video we're gonna talk about how to set up a multi camera shoot with the a-10 mini first I'll talk through what cameras I'd use and how I'd arrange them then how to wire it all up and finally I'll end with some thoughts about monitoring your video and what to do about the fact that the a-10 mini doesn't have a multi view output so the way I'm going to approach this is how I would do it if I were creating a multi-camera setup using the a-10 mini with an eye towards doing it effectively but also keeping it very budget-conscious the reason I say that is because this isn't the only way to do it you could have different cameras different room sizes and logistics to deal with a different volunteer pool to pull from all of which could change the approach you take when setting up your system but I hope as I show you how I'm setting up the various pieces to my system you'll get a foundation for building out the system that you need let's talk about the four inputs to the switcher I'm going to be bringing in a feed from a computer that is running lyric software and overlaying that over my video so that computer will be connected to input four of the AIDS and mini that leaves me with three cameras to work with I'm gonna use a canon or 800 for a static lockdown wide shot of my room and i like to have that connected to input one of my switcher I teach my volunteers who are directing video that if you ever get lost and don't know what to do go to camera 1 and you'll always have a shot that's usable when you panic hit camera one a common place to put this camera is in the center back of your room it could be right in your tech booth maybe even right next to your mini but I'm starting to actually prefer this shot to be a side shot where the stage is on one side of the frame and the congregation is on the other I've just been liking the way this shot feels and I think it gives a better sense of the room and therefore a better use of a static wide establishing shot for my second camera I'm gonna have that be my close follow shot that is manned by an operator this camera will be what I use to get close-ups and follow the speaker if they walk around on stage this would be a good camera to invest a little more money in and possibly get controls for the zoom and focus for the operator to use on their handles the Canon g21 would work well also let me just say it's really important to invest in a nice fluid head for the tripod I've got some links to a few suggestions for those down in the description of this video a good tripod is something to invest in it potentially is going to outlast your camera several times over and be with you for a long time and it makes a huge difference in the stability of your shots for the third camera I'm going to use a PTZ camera I've got the PTZ optics 30 X nd I camera but you could use the 12x model depending on the distance to your stage I'm gonna position that right next to my manned camera in the center back of the room you can control the PTZ optics camera right here in OBS with an additional plugin that you install and I also have a video about how to control them using an elgato stream deck I'm gonna have these two cameras operating in two different modes for lack of a better term one for worship and singing where the pace of my shots will be a little quicker and then a second mode when someone is speaking and I want to follow them closely in the first mode for faster paced stuff I'm gonna have my PTZ camera on whoever the lead singer is for a song and I can program memory presets for those locations into the camera then I'll have the manned camera picking up special interest shots close-ups of the guitar player when he plays a lead a shot of the drummer or various other shots that they will be cycling through a manned camera can change and react to different shots a lot quicker than you can with a PTZ camera so that's why I have them doing those shots then in the second mode when someone is speaking I'll change that up and have the manned camera operator follow the main subject in a cowboy shot and the PTZ camera moved to a medium shot of the stage or a full-length shot of the person speaking so that's my camera layout now let's talk about how to wire up these cameras the a-10 mini only has HDMI inputs and my general rule of thumb is never run HDMI cables longer than 15 feet so if your mini is located in your tech booth in your worship space and you're using something like my camera arrangement camera 2 & 3 could be located right in the booth with you in that case just run HDMI cables from those nearby cameras to the mini but for my static camera number one it's across the room so I need to run a longer cable HDMI was designed to connect your DVD player to your TV or your Xbox to your TV it wasn't really ever meant to send HD video signals over long distances so while you may find longer HDMI cables and all sorts of gimmicks for extending HDMI cables the vast majority of those are just that a gimmick and you're gonna pull your hair out dealing with them in my experience the most reliable and robust way to extend HDMI is to convert the signal at the camera to SDI using an HDMI to SDI converter then run the distance from your camera to the switcher with an SDI cable and then at the switcher convert the SDI signal back to HDMI with another one of these Blackmagic designs converters you can run SDI cables up to 300 feet without any issues so my advice is to run SDI cable whenever you can and an added benefit of this is that someday if you upgrade your cameras and your video system you'll already have the cabling in place to support an SDI system ok I know the question that is on a lot of your minds how do I get a multi-view with a 10 mini I know this because he fasted 100 time's already here on my channel here's my answer and it might not be popular but I think it's the right answer the a ten-minute does not have multi-view and if you really need multi-view save up and get the AMT vs HD which has multi-view built in there are a lot of videos here on YouTube that will show you how to rig up a bunch of splitters and adapters and create a multi-view and that will work and I'll link to one of the better ones down in the description of this video but there are two problems I see with doing this one you'll be introducing a whole bunch of failure points and complications into your setup and second by the time you've spent money on all the peripheral devices you'll need to make this work you've almost spent as much as you need for the a 10 TBS HD which not only has multi-view but also has SDI inputs and an aux output so a lot more functionality for the cost now there is one exception where I think it would become cost-effective to rig up a multi view and that's if you're converting all your inputs to SDI cables already maybe your switchers in a control room isolated from your event space and you need to run longer cables anyways or all your cameras already have SDI outputs either way the Blackmagic designs converters from SDI to HDMI that you'll already be using to convert your inputs back to HDMI for the switcher they have this pass-through connector that lets you run the SDI to another device as well in that case then I think it makes sense to use the Blackmagic designs multi-view 4 which takes 4 SDI inputs and generates a multi view on the output and it has an HDMI output that you can run to any TV so in that situation where you're already converting everything to and from SDI then I think it can make sense to add multi view but if you're not let's talk about how to run your event without multi view the first strategy you'll want to use is to put the mini into program preview mode you'll need to run the a temp setup program and change the default cut bus to program preview what that does is change how the 4 camera buttons and the cut and fade buttons operate in the default cut bus mode you select a cut or a fade and when you press a camera button that transition occurs immediately when you're in program preview mode you select a camera input and the button turns green the green input is routed to the preview bus so if we change the HDMI output to preview and connect a monitor to the HDMI output of the mini we can see that camera feed even though it's not live on the program output to take the camera live to the program output press the cut or fade button so in this way even though we don't have a multi view to see all of our cameras we can see what a camera is doing before we send it to our video another thing to consider is how many of your inputs do you really need to see in my setup I know the fourth input is my lyrics content and I know that camera one is a static shot already that's half my inputs I know what's on them without having to see them for camera two and three you may want to be able to see what they're doing all the time if you have a comm system and are directing the camera operator or just to set up your PTZ shots in that case an option is to get a monitor with HDMI pass-through I've got links to a few of these down in the description of this video to set this up you run the HDMI coming from your camera into the monitor first and then the output from the monitor into the mini now we have a dedicated monitor to see what's on one of our cameras so that's it we're ready to livestream a multi camera event with our 810 mini in my next video I'm going to talk about how to get lyrics and graphics into your switcher so be sure and subscribe and I'll see you next time bye
