It's a great day for Canon 5D Mark III owners ... If you do like to shoot with DSLR and this applies to some of my recent workshop attendees who often come with a wide array of different formats then this news is really important especially if you plan to do a lot of color grading and post work to your DSLR footage.
The new update from Canon means you can finally record a clean HDMI out and record to an Atomos Ninja 2 - this means you can shoot in ProRes 422 albeit 8 bit. The fact is when Canon released the 5D MArk III the new CODECS were a vast improvement on the old h.264 that we all had to deal with on the 5D Mark II and 7d. This is something I dedicated a whole chapter to recording CODECS in my video guide to shooting video on the Canon 5D Mark III
The big plus is in the ability for you to record a more solid CODEC and this is a big deal when you are color grading with advanced software such as DaVinci Resolve
But as the attendees of my workshops will vouch for...I always advise not to jump in with any announceents until you've figured out the caveats and what if's.
** UPDATE** (from Guy at hireacamera.com) one thing we omitted to mention in the video that I realised when looking at the footage from the Ninja 2 this morning is there is no audio. Unlike the camcorders, the 5D Mk III does not transmit the sound information through the HDMI. The solution to this is to link straight from the headphone socket through to the audio input on the recorder. We're going to do some more investigating on this to see if there is a better way. Whilst it won't produce the best quality sound, it should be more than enough to sync with an external recording device.
WARNING- We have discovered that the audio is not recording in sync and that it is out by around 5 frames. Guy has contacted Atomos to make them aware of this and hopefully we'll have an answer soon.
Guy has created an update video that explains a solution for audio
