The Canon EOS 5D Mark III can now get a clean video feed from its HDMI port. This allows the use of external recording devices like the Atomos Ninja 2. The latest alpha version of the Magic Lantern camera tool offers this feature as well as “gradual” exposure control, experimental peaking functions, various display tweaks and movie logging.
Canon has also announced a major firmware update for the camera that will be available from April 2013. This will also provide uncompressed HDMI Output Support:
“When shooting video, HDMI Output makes possible the recording of high-definition uncompressed video data (YCbCr 4:2:2, 8 bit) from the EOS 5D Mark III to an external recorder via the camera’s HDMI terminal.”
