Convenient operation. The built-in switches allow you to change the Mini Converter's settings on the fly. This is great when you need to be quick – without navigating through complicated menus. There's even a circuit diagram printed on each converter, so you don't have to reach for the manual. However, you can also specify settings using the supplied Converter Utility software. To do this, connect the converter to a Mac or PC. The software of all models can be updated via USB. Simply connect Mini Converter to a Mac or PC and install upgrades directly from the Blackmagic Design website.

Review: Video production must have! - This solved my video production camera compatibility issues for me. Though the configurations on the converter might be old, the installer has a more accurate instruction manual in pdf that has the various combinations for the desired output. If you are into video production, this will save your life and time. This is my second purchase.
Review: It's so useful. - I need this chiefly because BMD vision mixers tend to require every input to be the same resolution and frame rate. Unhelpful vision mixers! Having said that, this will help with one camera input, or one PC input. We have all cameras set to 1080i at 50 fps ("1080 i 50") but recently purchased two cameras at 1080 i 59.94 along with a cheap BMD mixer. Their Mini mixer outputs at 1080 p 50 and will need conversion to augment inputs to the main mixer. So the UpDownCross is useful. Our PC hasn't got a 1080 i 50 setting available (cheaper graphics card) and as graphics cards are so expensive just now, this might provide an alternative way forwards.

## Questions & Answers

**Q: Can i use this to convert a 720p hdmi to 1080i sdi?**
A: Yes you can. Mini Converter UpDownCross HD has the ability to convert any SD or HD video format with up, down, or cross conversion via SDI and HDMI. See page 83 on Blackmagic Converters Manual. 
https://www.blackmagicdesign.com/manuals/Converters/Blackmagic_Converters_Manual.pdf

**Q: The output matches the monitor; which monitor? i will input a laptop hdmi out to 2 different switchers; 1 via hdmi 1 via sdi.**
A: "Output supports EDID of the monitor". https://en.wikipedia.org/wiki/Extended_Display_Identification_Data

This simply means that the converter does not output a fixed format via HDMI, rather it will communicate with the connected display to handshake on what resolution the monitor prefers. If your outputs are going direct to switchers and not to a display/TV, then this should not affect you and converter will simply output what you set it up to do.

**Q: Will this converter let me use my iphone camera or apple tablet camera into atem mini switcher?**
A: Im not sure because the mini switcher allows you to switch video outputs during streaming.  The UpDownCross use one signal and let you distribute that signal through the sdi out and hdmi out..

**Q: Does this device come with a power supply?**
A: the one i ordered through here did
