Hi,

I'm new to VMIX. My company plan to purchase the license for our traffic tv program. Here are my setup.
1. Windows 10 running on Bootcamp Imac 2013.
2. Blackmagic Studio Camera -> Blackmagic Ultrastudio Express Thunderbolt
3. Sony HXR-MC1500 -> Blackmagic Intensity Shuttle USB3.0
4. Windows 7 Machine as input (Blackmagic Decklink Duo) -> Blackmagic Ultrastudio SDI USB3.0
5. Fullscreen Output via Thunderbolt to HDMI -> Blackmagic TV Studio
I'm having instability problem when having this setup. The USB3.0 inputs will hang and i need to restart vmix.
After some tinkering I've found that only one USB 3.0 input can be up at a time and stable. I'm not sure whether this is some kind of bugs or simply a hardware limitations. Please advise.
Thanks.

most likely issues with the USB controller. BMD devices are pecky. And not many USB driver/controllers can manage multiple (web)cams.
Magewells USB3 dongles are the most flexible ones I've used. At least 3 cams doing 720p

Hello,

I couldn't get more than 1 BM Equipment stable on a Mac Book Pro (or an Asus Laptop, or a HP Laptop, or Desktop Custom Built). Seemed to work with 2 reliably, then an small update or reboot and couldn't get it going again. I don't have any love for their capture equipment has given me many hours of headaches. I tried many driver versions from BM, they just said my computers were faulty or not compatible configurations.

Switched to Magewell, no regrets, no headaches. Same computers :) I have not bought a BM product in years and I sleep much better. I bought BM thinking they were the Standard/The Best but now avoid their products as they seem to work if you are very lucky. They were very fussy on drivers, video frame rates and resolutions, GoPros, USB 3 Controllers, which order they are plugged in and thunderbolt ports.

My experience was with the Thunderbolt Mini Recorder/Intensity Shuttle Thunderbolt and Intensity Shuttle USB3.

Thank you all for the replies. Currently the best option for me is to use one bm ultrastudio express and one ultrastudio sdi usb 3.0. Sadly i cant use my other ultrastudio sdi usb 3.0 and intensity shuttle usb 3.0. Is anyone here know any motherboard which supports thunderbolt and has dedicated usb 3.0 bus? My other option is to wait for vmix 17 and use the ndi feature to utilise my spare bm devices.

yuan has an affordable usb3 multi capture input devide with 3 sdi and 1 hdmi input. tested and approved for use with vmix i understand.

Some Gigabyte boards support thunderbolt, however found the usb3 bus didn't handle too many cameras on motherboards as they did share a bus and working that out was too time consuming on a desktop when a card is so cheap.

Best to add a full speed 4 port usb PCIE Card and leave the motherboard usb for running the mouse, keyboard and external hdds and memory sticks. USB 3 Cards are pretty cheap.

Here is the one that worked for me:

And if you are on a laptop and want more usb 3 and have thunderbolt this works well:

Other things may work just as well, but I only want to mention stuff I've tried :)

Note: Worked when populated with Magewell USB 3 Capture devices. Untested on BM devices.

If you have thunderbolt why not just use a thunderbolt capture? Instead of converting that to USB3 and loosing a lot of its available bandwidth.

I would suggest shifting things around a bit, thunderbolt has way way more bandwidth than USB3 (depending on version) and a single thunderbolt port could probably handle 3-4 1080p signals with no issues, so would suggest getting multi capture devices for each port then use your USB 3 to power your video out which isn't necessarily as high bandwidth.

How about Thunderbolt pcie enclosures with usb 3.0 pcie card? The fact is i already have a couple of bmd usb 3.0 dvices. I'm still evaluating between Thunderbolt dock and pcie expansion.

That I did, and I am strongly eyeballing that device, would like to see some more feedback on it though especially in regards to VMix before I jump on it.
