Related Questions and Answers

Q: 1. Do you need HDMI 2.0 to be able to do 3840x2160 at 60 fps or this converter with HDMI 1.4 can do 3840x2160 at 60 fps ? I thought HDMI 1.4 maximum frame rate at 3840x2160 resolution was 30 fps.

A: You would need HDMI 2.0 for UHD at 60 fps, which this converter does support as well. So if you have a device that outputs HDMI 2.0, it will work with this converter.

Q: 2. Will it down convert two separate 6G SDI inputs into two separate 3G SDI outputs? What about four to four of the same scenario?

A: No, the AJA 12GM 12G-SDI to/from SDI Muxer/DeMuxer reclocks signals and does not convert down or up. You will need an AJA UDC Up/Down/Cross Converter which handles one signal at a time.

Q: 3. Does AJA Hi5-12G 12G-SDI to HDIMI 2.0 Mini Converter support Dolby Vision?

A: AJA does have plans to release a future firmware update supporting Dolby Vision for the AJA Hi5-12G 12G-SDI to HDMI 2.0 Mini-Converter, but unfortunately it hasn't been released yet.

Q: 4. can this reclock/amplify 4 sdi signals without muxing? looking for a 4 camera distribution amp in one box.

A: Yes, the AJA 12GM 12G-SDI to/from SDI Muxer/DeMuxer can be configured as a 1x4 distribution amplifier.

Q: 5. 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: 6. Will this pass BMD camera control data?

A: Yes, the AJA KUMO 6464-12G Compact 12G-SDI Router (4 RU) will carry camera control data.

Q: 7. Does this unit matches framerate and size of ins and outs, or everything needs to be settled to match previously?

A: This unit does not have scaling built in. All Resolutions and Frame Rates need to match before it reaches the Kumo 3232 Router.

Q: 8. can this be configured as a 4x4 distro amp to simiply pass through each signal in a 4x camera setup to extend max cable length?

A: The AJA 12GM 12G-SDI to/from SDI Muxer/DeMuxer would be a very expensive distribution box. Instead use the Blackmagic Design Mini Converter SDI Distribution, for $165.00.

Q: 9. Can this be used between a Sony A7R2 (4K HDMI) and the older model Convergent Design 7Q (dual 3G-SDI)?

A: Yes, this can be used. Make sure it can accept Quadlink 4K.

Q: 10. Does this unit support Quad 4K and/or 2SI (over 4 cables)? Does it support 6G 4K@30Hz or 23.98 to Quad 4K@30Hz or 23.98?

A: The AJA 12GM supports Two Sample Interleave (2SI) to/from Square Division (Quadrant) pixel mapping as well as Quad link 3G-SDI to 12G SDI conversion. Also, 6G to 12G quad signals in 4k 30 and 23.98 are supported. Manual: https://bit.ly/3HgrzjC Framerates and I/O: https://bit.ly/41TTT4Q
