Q: 5. Does this device support 23.98psf?

A: This supports outputs up to UHD 4K60. It should work well for 24fps.

Q: 6. Does it have built in scaler?

A: The unit handles many resolutions and frame rates, but it's designed to convert the HDMI signal to the 12G-SDI (there will be no scaling involved -- it passes thru the exact same video stream that was sent in on the HDMI input). What it does well is, it acts as a distribution amplifier, giving you two identical signals that can go out via 12G-SDI, but no scaling is necessary for this purpose.

Q: 7. Does this work for GoPro 3?

A: yes only the black edition

Q: 8. I need to do a multicamera 4k UHD production with 4x Sony FS7. 4k output on FS7 is only via HDMI. I will be using Black Magic 4k Production Studio which has only SDI inputs. I assume I will need 4 of the Aja cards in the Open Gear Frame. Do the cards have HDMI inputs and SDI outputs? How can I achieve the foregoing using this set up?

A: Yes, this card has four 3G-SDI outputs and two HDMI 2.0 inputs. You would place these cards in the AJA openGear Rackmount Frame.

Q: 9. Hi all, can this converter convert from HD to SD?
