7D raw buffers cracked by Magic Lantern
 

Alex of magic latern announced that he found the raw buffers on the 7D and he got silent pics to work.

To recall, the path of development on the 5Ds was like this, first it was silent raw pics that record in bursts which eventually became continuous recording of raw onto the CF.
Hopefully the 7D follows that path.
Looks like its looking up for this dual digic beast.

Feel free to remove one Chris if this is redundant. Just felt to spice up the forums a bit.

EXCELLENT News

Re: 7D raw buffers cracked by Magic Lantern
 

This news could not have come at a better time. I was just about to put my 7D on ebay.

Re: 7D raw buffers cracked by Magic Lantern
 

There are now postings of burst mode raw video out. I definitely see raw video coming to this camera sooner than later. :)

Also, A1ex on Magic Lantern did a benchmark and found something peculiar, its the only canon dslr they tested where the write speed is significantly higher than the read speed.

Re: 7D raw buffers cracked by Magic Lantern
 

I too was about to get rid of mine! ;)

Re: 7D raw buffers cracked by Magic Lantern
 

A taste of what 7D raw video will look like. :)
This is from the raw burst mode.

Re: 7D raw buffers cracked by Magic Lantern
 

Wow.............

Re: 7D raw buffers cracked by Magic Lantern
 

+1, very nice looking

Re: 7D raw buffers cracked by Magic Lantern
 

This may be a dumb question, but what does raw video do for me?

Re: 7D raw buffers cracked by Magic Lantern
 

14 Bit uncompressed (almost) 90mbs 12 steps of latitude and stunning VERY gradable footage.

Re: 7D raw buffers cracked by Magic Lantern
 

Thanks Jerry. Would you typically convert it to another format before editing?

Re: 7D raw buffers cracked by Magic Lantern
 

You have to convert it after you grade it to edit. Workflow is a little more cumbersome, but the results look amazing from what I have seen online. I'm saving for a 5Diii right now, but this hack has me thinking.

Re: 7D raw buffers cracked by Magic Lantern
 

With 5D2 RAW, we are getting amazing results for green screen work. Our workflow is...

1) Copy to two locations.

2) With one location convert the files to individual, uncompressed DNGs.

3) Convert to compressed DNGs, which still have amazing quality and have roughly 5:1 compression. (Most of our pixels are green. "Normal" video might get 2:1 or 3:1.)

4) Make a Cineform proxy for editing.

5) After the rough edit with Cineform, do the effects and coloring work, using the selected files. Render to Cineform for the final assembly.

6) And so on...

BTW, we tried CineformRAW, which compresses REALLY REALLY FAST. But the quality was a step down from compressed DNGs. (It's a bit noisy.) Compressing with normal Cineform is slow, but gives better results than CineformRAW.

For normal video work, CineformRAW looks like the best way to go for fast turnaround with good quality. For effects work, however, Compressed DNGs have the best balance of quality and size.

In the end, we archive the Compressed DNGs rather than the originals or Uncompressed DNGs. Keep in mind that if you shoot a lot of RAW content, there are storage costs.

BTW, the results are amazingly good. Not only do we get tons on dynamic range without block artifacts, we avoid filtering and aliasing (we shoot crop mode) and the keys are fantastic. We can shoot long hair that is flung wildly and fast moving hands and pull excellent keys. :)

What a relief; perhaps my 7D kit will finally sell! I needed this news -- thanks for posting, Ted!

Re: 7D raw buffers cracked by Magic Lantern
 

Update.

ML devs scrambling to compile raw_rec module. Hold your breath....

What makes 7D more exciting is that along with 5DmkIII, they are the only canon dslrs with the sensor capability to shoot with the DUAL ISO feature made by ML dev A1ex.

Re: 7D raw buffers cracked by Magic Lantern
 

Ted, can you tell me if the 7d can output clean video thru the HDMI port.

Re: 7D raw buffers cracked by Magic Lantern
 

Using Magic Lantern I can turn off all overlays.

So on my external hdmi monitor only the pillar box is shown. The semi transparent letterbox is also removed.
Even when recording (h264) the red dot is not shown.

Re: 7D raw buffers cracked by Magic Lantern
 

You had me at, "... I can turn off all overlays."

(I could also use a built-in intervalometer.)

Talk about Christmas coming early! This is a ML hack I can't wait to try out.

I'd be looking around here to buy a used 7D, if I didn't already have one.

Re: 7D raw buffers cracked by Magic Lantern
 

Yes, intervalometer now built in. :)

And you can experiment with the dual iso trick. Extends the dynamic range of the image greatly. Photos only for now. Hopefully they can add this to the raw_rec module.

Re: 7D raw buffers cracked by Magic Lantern
 

Continuous Raw Recording on the 7D is now possible.
For now these are the resolutions that are continuous using 1000x cf card

24P & 30P
1728 x 576
1600 x 534
1472 x 626
1344 x 610
1280 x 582
1152 x 622

60P
1728 x 308
1600 x 382
1472 x 420
1344 x 436
1280 x 486
1152 x 464

Re: 7D raw buffers cracked by Magic Lantern
 

UPDATE!!

7D now near being fully functional raw recording.

Just tested a module compiled by an ML programmer named BRUNONIKO.

at 24P using 1000x cf card.

in 24P

1728 x 972 16:9 = Continuous

in Crop mode which is 30P since there is still no FPS over ride.

2152 x 1200 2.09:1 = 97

1920 x 1080 16:9 = 201

1728 x 736 2.35:1 =Continuous

1600 x 800 2:1 = Continuous

in 60P

1728 x 412 3:1 = 449

1600 x 382 3:1 = 2,610

1472 x 350 3:1 = Continuous

1280 X 416 2.20:1 = Continuous

Now full color realtime preview in liveview
(previously it freezes and has to be in grayscale)

Re: 7D raw buffers cracked by Magic Lantern
 

Hi Ted,

just wondering about the 60p modes - what options are there for 16:9? Does the 7D have the wierd pixel aspect ratio at 60p like the 5DmkIII does?

Thanks for the updates so far, I was losing track of the thread on the Magic Lantern forum!

Re: 7D raw buffers cracked by Magic Lantern
 

Hi John,

For now, I'm not getting a decent resolution with 16:9 aspect ratio.

What gives me continuous recording with the highest in vertical is 1280 x 416.

1728 x 412 gives approx 933 frames.

And yes, the pixel aspect is still squished.

I think one should use this for short effect purposes only.

Re: 7D raw buffers cracked by Magic Lantern
 

The latest update for 7D (oct 28), now you can playback Raw Video in COLOR in-camera.

Re: 7D raw buffers cracked by Magic Lantern
 

Just to add an update, the last couple of builds right up to the latest Nov. 3, the RAW Video in-camera playback is also improved.

After choosing file to view for playback, pressing SET starts the playback.

Press Pic Styles to show Controls, PLAY, PAUSE, HI(in color but slow),LO(grayscale faster) USE SET to SELECT.

Press Pic Styles again to remove Controls from screen. Press HALF Shutter to STOP Preview.

Re: 7D raw buffers cracked by Magic Lantern
 

Ted,

Can you share the link on where to get the latest build?

Thanks in advance,

Dano

Re: 7D raw buffers cracked by Magic Lantern
 

Dano,

Assuming you have already bootflaged your camera using the guide previously posted here,
HOW TO: A guide to installing ML on the 7D with recent features

Continue following daily updates by just replacing the files in your CF from here:
index · styled with h5ai 0.24.0 (http://larsjung.de/h5ai/)

Different developers are maintaining the compiles for different camera models.
This fork is still being merged into the unified ML so for the 7D, follow that ling maintained by developer called 1%.

...

Re: 7D raw buffers cracked by Magic Lantern
 

ted-

two questions:

will the ml hack work for the canon eos-m?

does ml work on the mac platform?

thanks in advance for any info you can share.

be well.

Re: 7D raw buffers cracked by Magic Lantern
 

Been using ML with my 7D on and off and figure I should mention it.

Do NOT ML with a bitrate hack (let alone raw) and an external HDMI monitor. You will get cloned frames from the processors maxing out and catching up

e.g. 1-2-3-4-4-4-7-8-9

Just FYI. Had to bring that footage into AE and interpolate the frames in between and re-export my masters. Wasnt something I was looking to deal with that day.

Re: 7D raw buffers cracked by Magic Lantern
 

Boy would it be nice to shoot ProRes on my 7D without making the leap to RAW. My system can't handle RAW...

Ignorant question: While RAW looks superb compared to H.264, but some of us have need of something better than h.264, but not necessarily as robust as RAW. For this reason I am considering the BMCC just to shoot ProRes (not RAW). Is there something in between???

Re: 7D raw buffers cracked by Magic Lantern
 

you could buy an atomos ninja, since magic lantern can remove all the info and focus box etc from your hdmi output. I do believe the semi transparent letterbox is still there which needs to be cropped in post.

Re: 7D raw buffers cracked by Magic Lantern
 

In your opinion(s), why don't more people do this? Wouldn't DSLR video folks prefer this to getting a separate field monitor and burning through CF cards?

Also, are the settings within Magic Lantern applied to the Ninja ProRes 422 recording, or does it record a stock setting?

Re: 7D raw buffers cracked by Magic Lantern
 

I have no ninja, but I know the ninja is set independently from the camera. Among the things that would impact it is resolution, picture style and fps since that is what that will be recorded through hdmi.
I could be wrong on one of those.

Re: 7D raw buffers cracked by Magic Lantern
 

Sucks that there isn't a medium-quality option for those of us who aren't equipped to handle RAW. If there is a Ninja recorder that can record ProRes 422, AND the EOS architecture can handle recording something as robust as RAW video, why isn't there an intermediary format, or the option to record directly to ProRes 422?

Please forgive the ignorance and excitement!

Re: 7D raw buffers cracked by Magic Lantern
 

what do you usually use video for? Long projects like events and weddings? or Corporate stuff thats shorter? I'm asking because I currently have a mid range quad core and I'm using it to run resolve which is free and do initial color grade of the RAW footage before exporting the clips to h264 for editing on my NLE.

Re: 7D raw buffers cracked by Magic Lantern
 

Somewhere between the noticeable artifacts of H.264 and the superbly rendered and data-rich RAW format.

Seems like someone much smarter than me could figure out a way to capture ProRes 422 in real-time, but I have no idea how complicated a task that would be.

Re: 7D raw buffers cracked by Magic Lantern
 

There are many many more variables in attempting to load logic into the hardware, than it is hooking into the raw buffers and extracting frames. Something that will not happen on DSLRs in the near future unless you want to get rowdy with essentially hard porting into the bus or interfacing to an external prores encoder via this as a sort of pass through if you can figure out communication.
