Check the Magewell site...they have a 6 input SD capture box that is USB, and I think they have SD & HD version......

Why?

My system shows my card as having 4 "Renesas USB 3.0 eXtensible Host Controller - 1.0(Microsoft)
But this is on Windows 10, and using the windows native drivers.
I haven't gone looking for the native Startech/Renesas drivers, however, it is working also.

If I run all 4 ports as USB cameras, it tends to really load down the resources on 10. I'll look into the updated driver, if there is one, but I think I'm going to have to do some more upgrading before I can use all 4 ports to their potential.

My i7-920 system running at 2.8GHz OC is getting a little long in the tooth now, as it was assembled in Dec, 2008.
vMix is really giving it a workout. But then again, for what it does, it should.

Thanks for the info!

On Starteck's installation CD the drivers are from 2013 and thats weird... Also I searched Renesas Site, but no luck, same old drivers.

I think I have to contact them, but any input from you guys is welcome!

Btw, where to see "recourses"?

Intel's X5680 is a very good choice indeed! I'm looking to build a beast too, I want to order and use 2x 4-HDMI Capture Cards (PCI) from Magewell, building that in a nice custom glass-windowed wall construction.

I'm using vMix for arena game streaming. I have 5 "Clients" streaming via FFMPEG RTSP to my VMIX rig, and need 5 webcam inputs from each. That's why I ordered a USB Hub. Another option is to use IP-Cams, but that will cost again much, and a Magewell Card costs already 900$.

Can someone explain to me why I can place 2 USB2 cameras on a USB hub and get 2 images in vMix from those 2 cameras, but if I try to do the same on a USB3 port I get a bandwidth notification?

I would think that as I have more bandwidth on the USB3 ports, I should be able to place more devices/cameras on each port before running out of bandwidth.

Will this be the same on USB 3.1 ports?

I've had as many as 3 webcams on a single USB2 port, but that 3rd camera was causing intermittent connectivity.

Thanks for the info!

I thought I had stated in this thread the webcams, but if not...
1 logitech c920
1 MS lifecam studio
2 logitech c270

the c920 was setup for 1080p
the other cameras were setup to use 720p

Can't say currently on the format they are set at because I just upgraded the processor from an i7-920 quad core running at 2.8GHz, to a Xeon 5680 hex core running at 3.5GHz, and vMix is waiting on becoming re activated.

Ok, have done some more testing.

Inputs:
1. Animated looping .mov background 1920x1080 29.97 fps
2. Animated transparent flag .mov 1920x1080 29.97 fps

4. C920 Logitech 1920x1080 MJPG, 29.97fps, no audio. zoom: 1.4, rotate Z:1.57
5. virtual input motion .mov background main, c920 overlay1, position zoom 1.274, Pan Y: 2
6. virtual input motion .mov background main, c920 overlay1, position zoom 1
7. virtual input motion .mov background main, c920 overlay1, position zoom 1, Pan Y: -1.48

15. HP webcam HD-2200 640x480 29.97fps, no audio, no position adjustments.

Output: NTSC 29.97p 1280x720 widescreen
FPS: 30 Render time: 12-20ms CPU: 28-32%

Overall CPU:36-44%
Recording bumps overall CPU to about 50%


Although that last camera is a crap webcam, I have 5 cameras on the system, with 4 on the Starteck USB 3 interface.

I think this will do for now.
I do have a Startech USB3HDCAP interface yet to connect and try. That's next.

I received a Logitech c930e Friday, so now I can run 3 1080p cams, and 2 720p cams. I Still haven't tried my xBox Kinect and my StarTech USB3HDCAP device yet. Of course the Kinect is not compatible with vMix, but I do use it with Visikord software. If only there was a virtual output in Visikord that I could input into vMix.

OK, Test completed... 30 FPS FULL HD Using Life Cam Studio and Rocket Raid worked perfectly! System is a 6 core AMD 6300 @ 4.4 GHZ with 3 SSD's 8 Gigs Memory... CPU 50%. I had 23 lost frames over a 6 min HD recording. I am VERY pleased with this software!!!!! Far better then anything else I have used.
