If you're using a computer with an HDMI output as a video source, the AJA ROI-HDMI Mini Converter allows you to select a region of interest and scale the output to fit your working resolution. Having ROI in hardware makes it easy to broadcast part of your computer's screen without the clutter of on-screen menus and the like. And because all the cropping and scaling is done using integrated hardware, video quality remains at a high standard. Embedded audio is passed through to the HDMI loop output and the SDI output. With the 3.5mm jack, you have the option of embedding analog stereo audio into the video output.

To adjust the ROI-HDMI, connect it via USB to a computer running AJA's free Mini-Config application. Using Mini-Config, all relevant settings can be changed with the intuitive GUI. A worldwide power supply is included and locks to the ROI-HDMI's power input for a secure connection.

Eliminate extra interface clutter and menu bars and extract only the portion of the computer screen you want. Use the included Mini-Config application to select the part of the frame you want to output and then choose how to scale the output resolution.

Take full control of aspect ratio and frame rate conversion with on-screen controls in the Mini-Config software that show you what your source and output will look like and what formats are coming in and going out. Simple graphical menu controls let you quickly choose the proper output for any situation.

The converter accepts 2-channel audio from the 3.5mm analog audio input or embedded 8-channel audio from an HDMI input. The audio source and routing can be selected in the Mini-Config software and is embedded in the SDI output. This allows computer audio to be embedded within the SDI signal for easy, synchronized routing.

Q: 6. does it convert 1080p to 4k?

A: No, this device does not convert 1080P to 4K.....4K is 4 times the resolution of 1080P (think 4 1080P signals combined). This device takes a video signal on an HDMI cable and converts it to an SDI cable. Why convert to an SDI cable? Because SDI cables can carry a video signal MUCH further than an HDMI cable can a video signal. What kind of input signals can this device handle and convert to SDI? It can handle video resolutions of 4K, 1080P and lower. But all it s does is convert the input signal from HDMI cable to SDI cable, it does not change the input resolution.....what goes in is what goes out....just over a different kind of cable that can handle longer distances than HDMI can handle. If you want to convert a signal from one resolution to another.....like 1080P to 4K or the reverse 4K to 1080P then you need a video scalar like this product from B and H......SC-HDM-HD42K 2-Port HDMI 4K Scaler from Avenview.

Q: 7. I am wanting to connect a 2013 iMac to a ATEM Television Studio Pro 4K. Would this Converter work if I used Mini DisplayPort to HDMI from the iMac, to the HDMI in on this Converter, and then passed SDI to the Switcher?

A: Hi, I don't have the switcher, but I do have the Blackmagic HDMI-SDI 6g, and an atomos shogun inferno, and a 2012 MacMini. I was able to see output from the Mac Mini at 1080p, but did not see any choices for higher resolution. I'm not sure that you can even pass 4:2:0 2160 signal at 30fps over a 3g input Blackmagic does make an admittedly more expensive HDMI - SDI convert to pass full UHD, BH #BLTRMHDMISDI • MFR #CONVNTRM/AB/HSDI (the Blackmagic Design Teranex Mini HDMI to SDI 12G Converter). I'm not a B&H employee, but they have a very reasonable return policy; you could ask if they wuold let you try the cheaper one, and if it didn't work, exchange it with more $$ for the faster one.

Q: 8. Could I use this device to convert the 8 bit 4.2.2 HDMI data coming out of the Sony a6300 to be recorded in my Oddesy 7Q, which only has 3G SDI input?

A: Yes, that should work.

Q: 9. Does this convert the audio from the SDI as well, and does it sync properly, I want to use this to convert my main out from a Blackmagic ATEM TV Studio HD Switcher?

A: Carson,Yes this converter will pass the audio from the SDI input to the HDMI output and the 1/4 phone jacks. Yes it syncs properly. We use a number of these in our studio and in the field with no issues. Make sure your connections are secure and you should have no issues.DJ Video
