Multicam Setup to Resolume

[Arvol]

These are my goto:

I use 2-3 and use USB capture devices. For your setup you'll need a desktop with a PCIe card.
Blackmagic and AJA make good ones.

If you're really on a budget, you could buy a good Wireless router (AC series) and have all of you guys install a NDI camera app on your phones and then route them into Resolume 6 as sources.

Be sure to hide the network name and secure it so no-one else get's on and eats up your bandwidth.

To be honest, the problem with external capture devices is the interface bandwidth in between the capture device and the computer. USB3 can only do 4k@30, Thunderbolt 3 can handle more, but there's only a handful of devices that support that, and those devices only support a single input.


Here's another method to get this working for you on a mobile setup, that doesn't involve outboard camera switchers:

If you don't need 1080p or higher resolutions for each of your cameras (outputting to led walls with actual pixels in the 720p range, or you don't mind up scaling), you could use this device:
http://decimator.com/Products/MultiView ... _Quad.html

Or this one, if you want a viewer:
http://lilliputweb.net/a12-lilliput-12- ... h-sdi.html

to take in 4 sources (the camera's I listed earlier are still my go to choice for on stage cameras).
From here you would send out a single 1080p signal to a capture device (I like Magewell and AJA) and then inside Resolume you could do a little magic.

You would add this capture device to it's own layer and then bypass the layer, then inside advanced output you could add 4 screens and set each of their slice inputs to the layer with the capture device and then resize the input slice to fit one of the 4 cameras, repeat with a different camera choice for each of the screens. (breaking the screen into quads). Be sure to un-check the two tick boxes at the top that involve layer opacity and bypass, this will prevent the quad view to come through to the composition.

Now put those 4 screens at the bottom of your list and set their outputs to Spout, then create a new screen and put it on top and set it's input to composition.

Close out of advanced output and add 1-4 new layer and add your 4 Spout input devices (the screens you just created) to one or all of those layers.

You now have a 4 camera switching system.

Be sure to set your original capture device clip to "Persistent" and always keep it on.

Your camera input resolution will be 960x540 if you're using a 1080p composition.
From there it is being resized to a 1080p output (2 times up scaling)

**********************************************************************************

If budget wasn't an option, I would just use a desktop with a 4-8 input capture card (AJA, Decklink, Blackmagic)

Here's a video demonstrating the method (layer 1 is acting as my input capture card, it's just a test card though... Same principle applies):

You can use outboard camera switchers as well if they give out a quad view.

If you are interested in the Decimator, Shoot me an offer and I'll sell you mine. I used it on one tour and its been collecting dust in my pelican case ever since.

Is probably one of the better solutions for 4k cameras and is supported by resolume.

Edit: meant 4x cameras. Technically it’s 4k via 4xsdi. But it’s not 4x 4k.

[Arvol]

That's impressive! I didn't know there was a non pcie in out option that allowed for more than 2 simultaneous inputs at once.
Thunderbolt makes sense.
Very cool.
Nice find.

I have used the OWC Mercury Helios 2 with Blackmagic PCIe cards many times and captured up to (5) 1080 p30 signals via Thunderbolt 2 using a Duo 2 and a Studio 2 and it worked great.

Now they have released the Mercury Helios 3 so I would think you could probably capture (8) 1080p30 with a Quad 2 card.

I've seen this done this before: Get some IP cameras, then bring their RTSP streams into Resolume. Zero additional hardware required (except an ethernet switch or wifi router). Quite inexpensive. Plus, you even get PTZ!
The ones I saw used were an older model of these: https://amcrest.com/amcrest-1080p-wifi- ... ra-pt.html

How are you bringing RTSP streams into resolume? Virtual device or sending over ndi/sport from a companion app?

Mac: Bring up the RTSP stream in VLC, then Syphon it into Resolume.
Windows: Bring up the RTSP stream in VLC, then NDI to Resolume. <-- I prefer this way.

I have the Amcrest camera IP2M-841EW (White) and I found the latency using OBS and VLC with Syphon or NDI to be unusable. The delay was 3-4 seconds when going through those applications. I found a relatively cost effective solution for <300ms latency using this IP camera.

I bought a Kiloview DC-220 IP camera RTSP to SDI/HDMI converter with an Elgato CamLink capture card. I connect the IP Camera via ethernet and POE injector to an Apple Airport Express router. The Kiloview RTSP converter connects via ethernet cable to the same Airport express. The HDMI output on the Kiloview goes into the Camlink capture device plugged into my computer. Once everything is configured resolume will see the camera as a capture device via the Camlink

The latency at 1080p/30 from resolume is under 300ms now and usable for almost real time live streaming to video screen for events. I noticed the latency if I plug the Kiloview directly into a display is about exactly the same as if I run it through resolume first. If I had a better capture card like a BMD or Aja the latency might even improve. I have not tried the SDI output yet, but that would likely improve latency.

Professional PTZ cameras can cost more than $2000. This is the most cost effective solution I have found for fairly low latency PTZ video into Resolume. With POE ethernet you only need one cable going to the camera and it can be hundreds of feet long. Wireless IP cameras are just too undependable and have to much latency. The system I built is rock solid.

Amcrest 841EW - $70
Kiloview DC 220 RTSP converter - $180 used, $246 new
POE injector - $20
Elgato Cam Link 4K - $130
------------------------------------
Total cost new $466

Not bad for 1080P/30 streaming PTZ camera with <300ms of latency. I think to get better than that you would have to buy a professional PTZ camera costing much, much more.
