I am looking at getting a new capture device so that I capture hdsdi input and use it live in vj software. I came across the HDX-SDI and it had mixed reviews on the capabilities of it being able to be used as a capture device out side of final cut or avid.

Is there anyone who has recently tried to do this? If it can is there any latency issues?

I am planning on using quartz composer so if anyone could try out this software for me before I purchase it, I would be grateful.
