We are a cable access station finally making the jump from SD to HD, we recently purchased 10 hpx170's and we are now running into issues in post. We are currently using a fleet of AJ-D230H to both capture and preview the timeline from FCP and AE. Now that we are working with P2 HD we don't need a capture deck and our current decks wont allow us to preview the HD video. (freezes and only refreshes when you stop playback.) We are looking to go with a card to install in the mac pro's that will provide HD video and audio outs and we have been looking more towards Blackmagic(and what card?) but is there something better for our needs?
