I need some serious help figuring out how to have FPS success using the Blackmagic Decklink cards. I need SDI functionality, and I want to use BMD. Resolume is advertised as working with Decklink cards. However, in all the circumstances I have used them, I have had terrible performance. Frame rate drops from 60 fps to 30 fps. Sometimes even 15-20. I have done the same thing straight out of graphics cards and even out of hdmi to sdi Decimators and it works great.
Why do Decklink cards not work? I know this cannot be the case for everyone. Has anyone had success with these? I really would like to use these, and it leaves a sour taste in my mouth when Resolume advertises that it works with Decklinks and it doesn't.
There is no way Decklinks suck for everyone. Someone has to use them with success. Anyone with tips?
