5DmkII Magic Lantern Raw Alpha 1

[Ted Ramasola]

5DmkII is out of pre-alpha and now has ALPHA 1.
For those who are following the nightly builds, the June 12 compile by developer a.d. is the module version of ALPHA 1.

Alpha 1 is for those who are starting from scratch.

There is now jun 13 NB (able to save your settings implemented )
https://bitbucket.org/a_d_/magic-lan...3385aa13bd.zip

here are SOME of the 5D raw resolutions, aspect ratio and its status. (using a 1000x Lexar CF card)

1880x1058 -- 16:9 -- 400 frames approx.

1880x940 -- 2:1 -- 1,900-2,400 frames approx.

1880x854 -- 2.20:1 -- stable/continuous til card full

1728x972 -- 16:9 -- stable/continuous til card full

1728x864 -- 2:1 -- stable/continuous til card full


In 3X (5X magnify) crop mode ( note for now NB jun 12, centering and cropping in this mode is off a bit to the left)
crop mode will give optimum results when used with FPS over ride (23.976)

2152x1078 -- 2:1 -- 184 frames approx.

2048x1078 -- 1.90:1 -- 242 frames approx.

1920x1078 -- 16:9 -- 335 frames

1880x1058 --16:9 -- 430 frames approx.

1880x854 -- 2.20:1 -- stable/continuous

1728x972 -- 16:9 -- stable/continuous

There are more resolution and aspect ratio combinations.

For now the raw video in the 5D2 records beyond the 4gig limit by spanning several files.

Programmers have written several programs to extract the dngs, combine the spanned files and convert them to files understood by most systems.

Post processing:

Aside from DNGs you also can convert them to Cinema DNGs to make them compatible with Resolve.

RAWanizer by developer Marten has a windows interface to batch process your raw files to DNGs, Tiffs or proxy files in Prores, MP4, DNxHD, Csupport for Cineform.
RAWanizer - windows batch generation of video files from RAW

Raw to Cinema DNG converter by developer Chmee for windows. I've tested this and the footage will open in both AE CS5 and Resolve.

RAWMagic by developer Thomas Worth converts raw to Cinema DNG works for Mac.
RAWMagic 1.0, a GUI CinemaDNG converter for Mac OS X!

So, is this ready for use in production? I'd say test it first and see if it works for you. If you already have a raw workflow and raw capable A camera, a BMC, red etc, I'd say you can use this as B cam for now.
Again, test it first if it works for you. If you're a DSLR shooter and want to use this in your project, test it and with a sound recorder, you might and could be succesfull in using this tool as it is now.

Thanks for keeping us updated , Ted. I am doing occasional testing on the nightly builds. so far it seem with my card (Komputerbay 1000x) that sound recording is really cutting into banwidth. is that your experience?

[Jon Fairhurst]

Chris,

Can you also achieve stable 1880x854 and 1728x972 recordings with your card?

Thanks!

[Chris Barcellos]

My results with the Komputerbay 1000x 64 gb card with June 14th build seem comparable with Teds. This is all without sound. Seems like this card starts getting into problems above 68 mbs. Here are some results aspect ratios I tried.


1880x1058 -- 16:9 -- 427 frames

1880x940 -- 2:1 -- 2900 frames

1880x808 -- 2.35:1 -- stable/and appears continuous, though I didn"t run till full card.

1728x972 -- 16:9 -- stable/and appears continuous, though I didn"t run till full card.

With the latter two, the reason I say appears to be continuous is that the ML buffer meter remains stable and unmoving with very little buffer using showing during the entire run.

Nice little feature on ML is the beep that can signal the start of first frame to synch with separate sound recorder.

[Ted Ramasola]

To Jon & Chris,

Since I can't update/edit my previous post, I'll just add my test results on the recent builds jun 13 and 14.

I'd also like to correct my results on 1728 x 972 since i ran a couple of tests today and try to make long recordings to try and fill up the cf card. 32gig 1000x Lexar.

1880x1058 -- 16:9 -- 400 frames approx.

1880x940 -- 2:1 -- 1,900-2,400 frames approx.

1880x854 -- 2.20:1 -- stable/continuous til card full

1728x972 -- 16:9 -- 10,000 frames approx. ( 7min ) This is already near 32gig card capacity.

1728x864 -- 2:1 -- stable/continuous til card full

I was able to push 1728x972 to go that far by having GD=off / FPS override=23.976 / preview=Hacked mode. Otherwise it will be 7,150 - 6,550 ish.

I confirmed that 1880 x 854 is stable till it fills up card. In my tests it goes up to a 29.7 Gig (31,930,872,768 bytes) file on a 32 Gig card.

It takes me 15 minutes approx to transfer that from CF to Hard drive via usb 2.

Using RAWanizer to merge and extract to DNG it takes 34 min approx.

This is on my Quad core i7 64 bit win 7 system.

Since it was a supermoon weekend, here's a frame from raw video i shot.
Using 5D2 with nikkor 80-200mm f2.8 at 200mm + 2x teleconverter + MLraw 3x crop = a 1,200mm shot ? :)

[Ted Ramasola]

With build dated Jun 27, ML developers have made significant progress allocating memory and increasing significantly the recording duration for RAW video.

On the 5D mkII new higher resolutions are now capable of recording continuously with a 1000x cf card. Performance have also improved on slower cards such as 600X.

Below are test results based on a 1000x lexar. FPS=23.976

At 1X

Resolution-------Number of frames

1872 x 1054-------1058
1872 x 1012-------4686
1872 x 936--------continuous
1872 x 850--------continuous
1856 x 1044-------2378
1856 x 928--------continuous
1728 x 972--------continuous
1472 x 1104-------continuous

Crop Mode 3X (5x magnify)

2144 x 1076-------371
2144 x 1072-------370
2144 x 974--------947
1920 x 1076-------1326
1856 x 1044-------continuous
1728 x 972---------continuous

Ted. How is audio end of things at this point? Are you using audio recording in raw?

[Ted Ramasola]

It looks like they've given up on it for now. In fact they removed the wav recording option for raw video in the 5D2 (can't confirm if its the same with 5d3).

They only left the sync beeps at start and end for syncing with your external recorder.

[Ted Ramasola]

Resolutions --No of frames@30P
1872 x 1054 --237
1872 x 1012 --312
1872 x 936 ---460
1872 x 850 ---770
1856 x 1044 --287
1856 x 928 ---489
1728 x 972 ---650
1728 x 864 ---3338
1472 x 1104 --701
1472 x 828 ---continuous
1600 x 900 ---continuous

Crop mode 3x
2144 x 1076 --132
2144 x 1072 --158
2144 x 974 ---213
1920 x 1076 --235
1856 x 1044 --294
1728 x 972 ---476
1600 x 900 ---continuous
1472 x 828 ---continuous


The highest res for continuous recording has indeed increased. Previous NB it was only at 1472x828 for 30P Now its at 1600x900.

Thanks Ted, I will check out the latest version this weekend to confirm.

[Jon Fairhurst]

Ted,

Do you know if there's any work on a 60 fps solution at lower resolutions? It's always been a shame that the crop cams get 720p60 while the big boys don't.

[Ted Ramasola]

It was brought up in a discussion and the best they could do for 5D2 is 33 via FPS override.

They mentioned its not possible due to hardware.

[Jon Fairhurst]

Bummer.

Clearly, if you sample few enough pixels, the sensor is fast enough. I'd guess that the limitation is due to the max speed of a clock line somewhere.

Could have been a killer feature!

[Ted Ramasola]

But you never know what those geniuses at ML will be able to do next. Raw was not practically useful if they'd have unlocked it years ago since the fast cards were not yet in the market. Who knows what hardware developments will allow them to do next. :)

60P on the 5D3 however will have some "upgrade" since you can do higher resolutions via crop mode not just 720P.
