crop_rec on steroids: 3K, 4K, 1080p48, full-resolution LiveView

[Luther]

Gottcha!

off topic: damn, this came to mind when I read your "Gottcha!", haha. Dropped hard here. Good to see progress, though.

[vonj]

could you possibly genlock your steampunk device's motor to the camera?
so the camera's card LED blinks a msec whenever a MLV frame was captured, signalling the stepper should advance one frame?
then the projector runs as fast as the camera is recording...

I can do that in my DIY projector!   How can I blink that LED? Which file (or some kind of hint where to look) must I modify to build a version that blinks the card LED?

how is 4K RAW continuous recording so far? is it achieved?

[ibrahim]

Don't load mlv_lite and mlv_rec at the same time. They will conflict with one another.

With the 650D and crop_rec_4k_mlv_snd try loading just mlv_lite and mlv_snd and report back.

Does the same rule apply with 5d3 firm 123?

Are there any cropmarks I can use that shows the correct framing on my LCD while recording in 3.5K 1:1 centered x5 in 16:9 and 2.35:1?

I wil test and let you know soon. I have bought a 5d amrk III but havent started testing as i dont have any cf cards with me atm

Worked on my 5D3 crop_rec.c code in this branch:

- Refined anamorphic presets so it now gives continuous:
1808x2300(2:35.1) = 5425 x 2300
1360x2300(16:9)    = 4080 x 2300

- Also adressed the battery pull issue happening when in 48fps or mv720p 3x3 mode. Workaround allows for looping through x5,x10 and back into x1 mode.

- cine.lua included
- set_25fps in crop mode sub menu working with anamorphic mode
- bitdepth modes in crop mode sub menu working for all presets
- not included sd_uhs(don´t see why sd patching would be needed with mlv_lite anyway)

In terms of image quality and performance the anamorphic mode on this camera outruns anything coming from eosm, 100d etc...

@Danne

Just copied over only new crop_rec.mo (Is that ok?)

Anamorphic mode:

Getting slow saves. Cannot playback: 'Invalid RAW: A:/DCIM/100EOS5D/M23-1032.MLV

Any ideas?

Thanks!

@Danne

Why would that work? Use the complete build. There´s plenty going on at other places in code as well.

[timbytheriver]

@Danne

Just checking! Thanks, will try again.

[timbytheriver]

Still the same errors with complete new build:

In Anamorphic: Sometimes Hi contrast Green / Black display

Getting slow saves. Cannot playback: 'Invalid RAW: A:/DCIM/100EOS5D/M23-1032.MLV

CF card reports FULL when not.

My CF card now isn't recognized by mac. 'Initialize / Eject'.

Reverted to old build, all fine expect CF card still not being recognized by mac.

Oddness! Any ideas?

Cheers.

[Danne]

Could you give exact settings? What firmware version?
Are you recording to SD card? CF card problem persists maybe from first test where you ran only the crop_rec.mo module.
Others tested yet?
Everything works here on 1.1.3.

In Anamorphic: Sometimes Hi contrast Green / Black display

this one is confirm i too get green black preview. image is clean though after recording

i was trying for some slowmotion video. i set to ntsc 30fps 1080p and increase the fps til 40 as it cant go beyond 40.
and tried shooting in 10bit. i get lots of pink/corrupted frames. i tried both with dannes's build and the build from the experimentel page
if i set to lossless i get error msg. i donkt know if it is known issue
here im sharing a mlv file  https://ufile.io/6o30xfal

[Danne]

Greenish preview will occur when crop mode sub menu bitdepth is lowered. Expected because I lower the analog gain. Workaround.
Overriding to 40 fps in mv1080p will probably not work. That´s why you have the mv720p 3x3 preset. Or why not use the crop_rec 48 fps preset?

[timbytheriver]

Ok. Reverted to old build – working.
Tried another card reader – which seems to work now:

Formatted CF card in Mac to ExFat / Master Boot Record scheme.

Re-installed clean version of today's build on SD card. Loaded minimal modules.

Set to straight 1080p. Pressing stop doesn't stop recording. Eventually stops itself (20second approx).

Try to playback file. Get a flash of a yellow question mark on screen, then "Cannot playback: 'Invalid RAW: A:/DCIM/100EOS5D/M23-1032.MLV'

Then CARD FULL message. (Even though it is fresh) Looking on the CF card in mac shows no .mlv saved.

I'm on 1.1.3 recording to CF.

 

[Danne]

As I said. It works over here.
I still don´t know full settings set up so cannot try to reproduce. "Loaded minmal modules"? Set straight to 1080p? Maybe you have a faulty CF card. Sounds like it.

its greenish and black so nothing can be seen while recording

Overriding to 40 fps in mv1080p will probably not work. That´s why you have the mv720p 3x3 preset. Or why not use the crop_rec 48 fps preset?

i tried fps overiding in 1080p because all other presets have problem with preview. not possible to shoot a moving object.
fps override in 1080p is pretty good with the correct framing and real time preview. it wil be fantastic if there is a way to get rid of those pinkcorrupted frams

@Danne
modules loaded: crop_rec, mlv_snd, mlv_lite, mlv_play
res: 1920x1080p /14bit lossless (not crop mode)
CF (KB1066x) card seems to be working/saving fine when I revert to a previous 4K_crop-rec Danne build 2/4/19

Still odd...

[Danne]

[andy kh]

now it works im not sure what i had done in my first test. now i just clean install and turn on the anarmophic preset in crop rec and no more greenish black preview. i have a very slow 4gb cf card atm. wil test more as soon a i recieved another card

[Kharak]

Just thinking here.

Everyone likes buzzwords, right?. So wouldn't it be cool to change some of the Crop_rec presets' names for the 5D3? Like 3x Crop mode is as close to Super 16 as it gets. (12,35x7,5) / (12,4x7) 36x24:3 = 12x8.

3.5k mode equals 1.65 crop. 35 mm Film is about 1.7'ish crop not to be confused with Super 35's 1.5 crop which ML also can achieve, but in not so favorable recording times. 

With all the talk I see in youtube videos about emulating film or sticking to "true" cinema etc. I think adding some buzzwords could boost the popularity of ML further.

'Super 16 Mode' and '35 mm Film'?

I've been shooting a lot with a ultra wide vintage lens in "super 16" mode and the look is just fantastic, kinda feels like a little camera within the camera

Anyways, just an idea I've been contemplating.

[timbytheriver]

@Kharak I agree with idea behind this. Labelling presets with an established filmic title makes them more meaningful within the context, and easier to spot in the menu. The problem occurs not with the established film conventions such as Super 35, Super 16, 2.35:1, etc., but with the still developing plethora of digital conventions. Despite an extensive Wikipedia entry I see confusion (myself included) in many conversations as to what exactly UHD is Vs 4K, or 3K (which isn't really any fixed standard) or heaven help: QHD. Just sayin...

[Kiririn]

Got the mlv_lite lossless aspect of this working nicely on a 70D!

Out of the box the crop_rec_4k_mlv_snd branch didnt work - symptoms were soft-freezing when entering the ML menu video tab in video mode, and inability to start recording. After a copy+paste of these changes, it works perfectly: https://bitbucket.org/hudson/magic-lantern/commits/91593cabf6c9a97541b7f7de5f633b21ff75ad83?at=crop_rec_4k

As this is my first post I'd like to say absolutely excellent work to all involved! I will try to find some time to contribute properly

[jimiz]

your opinion.... we can use a CF adapter (type II) > SD card ... to take advantage of the excellent fast now, even from 256 GB with prices significantly lower than 128Gb CF, compatible to recording continuos  the ML raw HD 14bit (5d3)
like the Computerbay x1000..ecc...

maybe someone has already tried

[Walter Schulz]

Short story: Most CF/SD adapter are crap. Strongly recommend not to use this. We had lots of incompatibility issues and performance is ... well ... crap, too.
