We’ve been selling the BlackMagic Design HDMI to SDI mini converter box, and it has quickly become popular with our clients. It is the only HDMI to SDI converter that will accept both HD HDMI signals, as well as the SD HDMI signal from the 5D Mark II camera. For those of you that don’t know this unusual fact, the 5D Mark II outputs HD HDMI until you hit record. When recording, the signal changes to SD and most converter boxes just stop working. BlackMagic’s box will work with both signals, at least up until recently. BlackMagic released a new firmware for their box – version 1.5 – which has some nice fixes but it also happens to break the SD conversion option. If you upgraded your BlackMagic, or just purchased one recently, then it might not work 100% with the 5D Mark II. BlackMagic knows about the problem and will address it in the next firmware, but until then we recommend sticking with firmware version 1.4. You can easily downgrade the box also if you are having this problem. Download the firmware version 1.4 for Mac here, or for Windows here and just attach the converter via a USB cable – it should only take a couple of seconds to install.
