Capture external audio and video with Ultrastudio 4k extreme

Is there a software package or NLE that would be able to capture video and audio?

We are using the Ultrasudio 4k Extreme and RME madiface for audio. I haven't found any good information on this and only 1 piece of software where I could use select a different source for audio.

Have you tried Blackmagic's own Media Express that comes as part of the Desktop Video install package? That's what I use for first level capture from tape on three Blackmagic-based hardware systems.

Yes, I have already checked the Media Express software and does not have support for external audio. Also spoke with support and they said it doesn't. They were pretty rude about it.

UltraStudio 4K Extreme supports up to 8 channels embedded in HDMI, 16 embedded in SDI.

You would need some 3rd party solution, maybe ToolsOnAir or QTake, but these are quite expensive. In the same time any solution which uses separate path for video and audio is prone to sync issues and should be avoided if possible.

Mac or PC? If PC, try AmaRecTV, a free software program that lets you mix and match audio and video inputs.
As for lip-sync issues, try it out and see, won't cost anything. I haven't noticed that problem, but haven't specifically looked for it either.
It has a nice feature that lists dropped frames. Been 100% stable so far (about 30 hours of capturing) on my Win7 system.
Not sure it will work on a 4k cap card, I use it with the Intensity Pro non 4k, as well as a cheapie AverMedia C027 card.
It has a fairly small footprint, only a few MBs. It is recommended to check all downloads at the virustotal website to check for problems before loading any software from the internet.

Edit: AmaRecTV can be run from a folder, without installing.
