Look Canon, here is the source code http://bitbucket.org/hudson/magic-lantern/overview
Please tweak it a little so it works on your nice newly 5d4  ;D

KelvinK, do you have a reference for the 5D mark IV not supporting UHS-II in its SD slot? Such as a link to where those specifications are from. Canon Rumors don't specify the speed, and I haven't found its speed mentioned in any of the other rumor locations, but this really is an important feature (to be UHS-II) and I would really hope Canon would include it.

The 5D mark iii didn't support UHS-I and was limited to 133x (20MB/s), which is why it is so important to use CF cards. The 6D was released later and supported UHS-I, and card tests at the time showed many cards transferring at 35-36 MB/s. UHS-II has been released and the fastest SD card I can find is the Lexar Professional 2000x UHS-II SDXC which is 300MB/s. As opposed to available CF cards max speed of 160MB/s.

That same SD card in tests has shown extended write speeds of 250MB/s. For a camera that doesn't have CFast 2, to me this would be an acceptable downgrade and if ML can produce Raw 4K, then I would definitely like the fastest card available. UHS-I makes me cringe!

I have a 4K monitor and although I mostly take photos, I would also like to create landscape screensavers, such as waves crashing on rocks etc. So I'm really looking forward to what ML can do with the 5D Mark iv. I'm not sure how I can contribute, but I would really like to.

UHS-I can be found from the original source:

I see that HDMI is limited to Full HD only. Boo! Is it humanly possible that ML could hack this so that I could get 4K to my Pix-e5?

My Dinamic range bet is: 12.90 EV.

@a1ex can calculate this at iso 100, normalized at the size of the frame  cropped for video at the new (same as 1D II) Digic 6 +

if the camera can write at least at 130mb/s and we could get 2.5k/24 or 1920x818/50fps nonstop i would be happy. also waiting for some sensor testing for the most critical aspect- DR.
and ofc lets pray for some1 to port ML :)

Most of these as expected:
- DCI 4K (not UHD) center crop 1.74x
- 500 Mbps in 8-bit 4:2:2 at 29.97, 25, 24, 23.98 fps
- FullHD 59.94fps 4:2:0 8-bit
- External recording uncompressed 1080 YCbCr 4:2:2 8-bit, no 4K
- HDMI 1.3
- USB 3.0
- Same CF card, SD card is UHS-I only
- Single Digic 6+, however, promo video shows Digic 6 also:

I really hope that Magic Lantern RAW video support is possible on the 5D Mark IV for 4K recording!~

Yes still very exiting as a possible RAW hack camera, to have a raw camera with autofocus is great potential.  not so much interesting without hack for video work.

OK trying to sum some thoughts up, hardware limitations currently reducing possibilities with Magic Lantern....
These are limitations with CF card system, and CPU buffer, right?

To get that DCI 4K at 25, 24, 23.98 fps RAW would hit that limitation?
Motion JPEG is heavy tough. RAW might be easier? Also the crop helps?
Sadly it's weird crop for traditional framing, but not the worst.
USB 3.0 some help for the Dev's?
And new Digic 6+ power.

Latest 5D mark III firmware didn't dance so well with ML?
6D Mark II coming up 2017 probably with better 4K crop factor.


Edit: Maybe 12-bit/10-bit 4K/FullHD RAW could be easier?

Wonder if ML would be able to do the 4K RAW without crop or am i misunderstanding that possibility?

1.74x crop is very meh to me..

But then again, full frame dci 4k 500 mbps 422 would cannibalize on their cinema line. So not very surprising that their flagship photo camera does not have anything serious to offer in the video department.

I was expecting a soft pixel bined 4k h264 image.

Even 2.5 k raw 1:1 will result in something like 3x crop. Also useless, but who knows.. This is Magic Lantern after all and the magic the developers here have made in the past and today proves to me, never to say never.

I also noticed the dual or two cpu's in the promo video. A digic 6+ and digic 6, so some serious cpu power. But I got a feeling Canon made some extra effort to prevent hacking.. No source just looking at how the 5D ML III took its share of the C100 line. I dont think they want a repeat of that, as in no C-log for the 1dx II and mkIV.

But overall it looks like an amazing photographic camera.

Epic Canon fail. I sure hope ML can come to my 7D2 soon or I might finally be done with Canon.

I would take anything Andrew Reid writes with a grain of salt. He is consumed with fanboyism and contradictions as he "reviews" cameras on speccs rather than usage. Basically the entire eoshd forum is that way, where people are extremely offended with negative reviews of their purchases or eager to promote why their camera is still the best.

But eoshd has a really good anamorphic forum.

And its "sarcastic" @katrikura

IMHO

well 1.74x crop would be ok if you could mount EFs lenses, there are some good ones that are sharp enough for 4K, good that most 3rd party manufacturers like sigma, tamron and tokina make their glass EF not EFs mount, despite not covering the FF sensor. So unless there are some other huge problems like moire it is still a good option then. tough if it got moire then - sorry, but canon really screwed this up then...

@ansius  Do you expect people change lenses for stills and video? This is ridiculous. 4 years of anticipation for 4k 1.74x crop mode. And mono mic is a just a joke too. QQ.

I Think Canon did I Good job ! Considering there have a complete Line of Cine Cameras .   
From what I can see & read it looks like there used 1DC firmware Video functions in to the 5d4 .
Canon did say there where going to make 5d4 a Low cost High quality Video rich feature dslr and for 3499.00 USD .
You could spend twice that and get a c100 and get all those video cameras extra , Oh but wait AVC 4.2.0 and no 4K 4.2.2 DCI
Or C300 Mrk2 and get 10bit 4k raw 12,000 USD , So yea 5d4 is what I expected . Can't wait to get a hands on when my Camera Store
gets one in stock . And of course there will be firmware updates that could unlock more features I'm betting .

I see only 2 draw backs but not really a problem,
1st) 29:59 minute record limit (since this is no longer required anymore , I  think there are protecting the Cine/Video Camera lines)
2nd) Picture Style , I would have like to see the Canon C-Log but there is room for 3 user picture style profiles , So Technicolor CineStyle should work
Or the 1DC's VideoX picture Style VideoX picture Style

Is this true, no chance currently for non-CROP 1.73x 4K?

"Based on their current understanding and implementation of RAW video, they can only crop in to a smaller area, not expanding the imaging area." :

Correct me if i'm wrong, but isn't the RED cameras at 4K a 1.73x CROP aka Super 35mm?  I checked out this tool, and it seems that the Canon 5D Mark IV 1.73x Crop is going to be the same as what a RED Camera is at 4K ... aka Super 35mm ...
