Q: 1. Is there a scaler on this unit?

A: Yes it does. This is an up/down/cross converter which will do frame rate conversions and scaling.

Q: 2. Will it convert from 1080p 50 frames to 1080i 50 frames?

A: Yes indeed. Great unit!

Q: 3. Has anyone used this to input HDMI from PC to an SDI input , on the BMD 1 M/E Switcher? We tried using a Decimator MD-HX and have not had any luck.Thanks!

A: 1st, your Payload: BMD ATEM by default is 1080i / 59.94; Delivery: SMPTE Level B. Your Decimator MD-HX, those are configured by default as Output Converters. Install the Decimator control Panel to configure (Decimator)as an Input Converter. It will do what you want.The DAC-70s are SMPTE Level A. At 1080i / 59.94, they will work as long as the Payload remains 1080i / 59.94. Delivery: SMPTE Level A or B, does not matter at that rate. We use both DAC-70's & Decimators, among other Converters, with our BMD ATEM 2 M/E Production Studio 4K Video Switch. Hope that helps!

Q: 4. Anyone know the processing delay? Want to bring a consumer HDMI camera into a 720p system, for IMAG. Thanks in advance for your input.

A: No delay. I have used it for IMAG. SOLID PERFORMANCE.

Q: 5. Does DataVideo DAC-70 support SMPTE Level B?

Q: 6. Does this allow for a usb out? It shows a usb port but doesn't mention it in the specs

A: The mini-USB port is used only for device control (using Windows-only software) and firmware updates.Google dac-70 manual for more info.

Q: 7. Is it possible to force the output HD-SDI signal type to be 1080p @ 29.97 regardless of the HDMI or VGA input frequency? and does HDCP pass through this device, such as putting this in line with a computer to a TV and tapping off to use for recording from the HD-SDI output?

A: I use this device for connecting various computers to my professional video switching systems. Yes, whatever the input is, the output is a stable signal at a number of different standards, including 1080p @29.97.I haven't run across any problems with HDCP blocking my use of the signal.That said, I don't recommend using ANY product to bypass HDCP protocols.YMMV....Good luck!Kevin Lawson

Q: 8. Eternally grateful for your input... If input VGA at 1024x768 and it is set to output at 1080, will I see pillar boxes and a slight letterbox at the top since it is outputting 1:1 or will it fit to the vertical height? How about for 720? Thanks!!! Steve

A: We are using it similar to what you are describing. If you put VGA in and set output to 1080 it will be full screen. As far as 720, we have not used it yet.Lenny

Q: 9. I have a Free To Air Satellite Receiver that receives and displays most Ku Band Satellite TV channels in 720p HD format, which is watchable but oftentimes annoying; nowhere near the 1080i quality I would like. So if I ran an HDMI cable from the Free To Air satellite reciever to the Up Converter, and another HDMI cable from the converter to my TV, will I get the nice crystal clear detailed 1080i picture instead? Or will it still look fuzzy and kind of out of focus? I'm willing to blow the money for your product if it will display in true clear detailed 1080i quality. I hope you can please let me know. Thanks!

A: This is a great converter. I've bought a few of them for various applications. It will absolutely do the conversion you're asking about. The quality you get on the output will be entirely dependant upon what you put in. If your source is HD then you can expect a good picture going up to 1080.

Q: 10. Does this unit include the power supply?

A: Yes, this includes the AJA DWP-U-R1 Worldwide Power Supply for AJA Mini-Converters B&H # AJDWPUR1.
