I'm wondering if this device would recognise the ***.raw file on the compact flash card and back it up to the inbuilt sata hard drive?

That way you wouldn't have to spend so much on compact flash cards and could be backing up a card while shooting with another...  8)

Take a look at this.


That looks interesting (dimensionally too wide), plus the MKIII does not power up with the card flap open..

interesting times...

It would have to be some kind of port extension device that plugs into the compact flash socket on the MKIII and a cable (You'd have to drill a hole in the flap) that then plugs into the drive..

I'm sure it would be doable..

EDIT: Something like this could be modded to work...

the main problem is the fact that the HDMI hardware module does some colorspace transformation on its own.
we cannot simply send our data as we want it and we dont know much about the configuration of the HDMI controller.

we are aware of possibilities, but we are happy to present what we have right now. :)
but thanks for providing alternative theories :)

Understood, however even 8bit 2.2.2 (with the added vertical resolution from the ML hack) would be better than the mushy video via HDMI at present..

I appreciate it's not just as simple as flicking a switch :) I just feel, given the input from someone knowledgeable in the HDMI controller possibilities could become realities :)

For starters the HDMI spec is 8bit 422, this is 14bit RAW 4444. The ninja only does 442 too.

"To ensure baseline compatibility between different HDMI sources and displays (as well as backward compatibility with the electrically compatible DVI standard) all HDMI devices must support the sRGB color space at 8 bits per component.[51] Support for the YCbCr color space and higher color depths ("deep color") is optional. HDMI permits sRGB 4:4:4 chroma subsampling (8–16 bits per component), xvYCC 4:4:4 chroma subsampling (8–16 bits per component), YCbCr 4:4:4 chroma subsampling (8–16 bits per component), or YCbCr 4:2:2 chroma subsampling (8–12 bits per component).[52][53] The color spaces that can be used by HDMI are ITU-R BT.601, ITU-R BT.709-5 and IEC 61966-2-4.[52]"

Atomos should send Ninja2's to each of the developers... :)

I'm crossing my fingers that it's eventually possible, as it would reduce the pain/expense of working with multiple cards..

Either way, this is all very exciting :-)

ML only works on 1.1.3 for now, but you should be able to upgrade and downgrade.

If Canon likes us, we'll be able to update ML to work with the new firmware.

If Canon were to somehow restrict/disable the ability to use Magic Lantern  :o it would be public suicide as I'm sure many users would think twice about buying Canon products in the future. Especially when the market has so many choices of products with the likes of Blackmagic etc..

I own a couple of 550d's and a 5DMKIII and Magic Lantern is the only thing that makes them anywhere near reliable to use on mission critical jobs.

Excellent work as always by everyone involved in ML development, looking forward to the weekly build.  8)
