One would think that similar products from the same company would be compatible but with Matrox, that is woefully wrong. A few months ago we bought 2 [Matrox Mojito MAX](http://www.matrox.com/video/en/products/mojito_max/streaming/) cards because I had assumed the [BlackMagic Intensity Pro](http://www.blackmagicdesign.com/products/intensity/) cards we were using were bad (turns out it was the motherboard). They worked great for capturing HDMI except we could never get it to capture the [HD-SDI](http://en.wikipedia.org/wiki/Serial_digital_interface) signal from our [Canon XF105](http://www.canon.ca/inetCA/products?m=gp&pid=4796). My desire to use the BNC connector drove me to buying the [Matrox VS4](http://www.matrox.com/video/en/products/vs4/) because it claimed it did resolution and frame rate detection and it did in fact deliver on that promise. When plugging in the camera with HD-SDI we found that it did indeed work which was relieving and we quickly identified the cable as the problem. However there was a huge snag, we were forced to uninstall the Mojito MAX drivers to use the card and when trying to reinstall them, we were forced to uninstall the VS4 drivers. A quick call to Matrox customer support confirmed that the cards are not compatible and attempting to manually install the drivers caused BSoD on our livestreaming rig. The return process was pretty painfree.
I’m planning on doing a bunch of posts about what I’ve learned does and does not work for livestreaming company events in the coming weeks. So stay tuned.
