Question 1

Can this record to 2 separate channels?

Accepted Answer

This card can accept an input from ONE video source at a time, using either the HDMI or SDI port, but not both at once. Black Magic does make cards with multiple active inputs, such as DeckLink Duo 2, if you need that functionality.

Question 2

Will this capture 7.1 sound (dolby digital/digital+/truehd), ac3 (this is what cable/satellite boxes use and i don't need to support idevices)?

Accepted Answer

Tested it will pass 8 channel but will cause a cracking noise in the audio. Usually when you use this you use the stero track to line up the good audio which could be a 7.1 or 5.1 track. AC3 uses 6 wav files packed in a container called ac3. You can extract these to wavs import to davanci resolve and line up or some called sinc the audio then export out a 5.1 ac3 with the video. Usually a prores 422 is a good import codec. Google gereral1 and you can learn how to do this with videos I created to teach you how to capture with this thing. The raw capture in media express you cannot use. 12 gig every so many sec. You need to capture to prores 422 into a video editor then export out 422 10bit then encode to a deliverable format like h265 or h264. You never work native with post production codecs. This is a great card. It wlll capture the 8 channels on uhd signal but the cracking makes it only good for a sinc audio function. I own a happauge col2 and it does perfect ac3 in AAC at 660kbs which is the max bitrate for 6 channel toslink fibre optic capture. I use this card for studio work.
