Hello! I am currently using the trial version of VMix to test the setup I have built for use at my local church.

To test out VMix I have acquired some LifeCam Studio webcams but ultimately we will be using up to four HD camcorders connected to a multi-input HD/SDI capture card like the MAGEWELL XI400DE-SDI.

Anyways the problem I am experiencing occurs after pressing "Start" in the MultiCorder window. I am receiving the following error message regardless of how many webcams are connected to the PC:

Recording timed out waiting for first frame.

MC_OK.Buffer_WFF


I have played around with the settings to no avail. It doesn't matter what USB port(s) I am using either (USB 3.0/2.0, front/back etc). I made a video of what is happening. It can be downloaded it here: https://www.mediafire.com/?rvust55w55bf5rl

Just in case here is what my setup looks like:

Microsoft Windows 7 Professional 64-bit
ASUS Vanguard B85 Motherboard (UEFI BIOS)
Intel Core i7 4770
8GB (2x4GB) 1600MHZ DDR3
Nvidia GTX 650 1GB GDDR5 by MSI
2 500GB HDDs (Software RAID, Mirrored)
2 120GB SSDs (Software RAID, Mirrored)


Any help is greatly appreciated. Thanks so much!!

Edit:
Also I have no problem capturing using the regular recorder. It is just the MultiCorder that is giving me this issue.

I spent some more time on this and have found that the issue doesn't exist prior to version 12. So until this bug gets fixed I'm using v11.

MultiCorder is designed to be used with capture cards, so it is not really supported
for use with webcams as they generally have variable frame rates which can cause havoc with the MultiCorder.

Okay, that makes sense. Though it is a nice feature for testing purposes. Just thankful it is working in the older versions.
