better dr
better low light
better gradation
better color (subjective)

so, although 3.5k has workable dual iso, this does not compensate the full sensor's advantage.

Already been discussed here.
The DR is the same because 3.5k is just a crop of the full frame, the sensor capability remains the same

In Preview (no recording) I see the usual icons like exposure or ISO. During recording, there is only a green Camera icon, 67MB/s 17% idle and that's all. I enabled LV sharpening and it is visible (very helpful for focus).

You need to disable "kill global draw" in raw options.

Great new features.

It works pretty well. But I also have one side effects If I use grayscale preview, I can't switch back from crop preview if I press half shutter.
It's linked with timing tweak.

Maybe you can add a other option to change resolution between idle and recording. It would be Nice to have half colour resolution before and quarter colour resolution when recording.

Thank you!

Good tip! Does zebra work correctly enough to avoid it? Or there are some nuances? I was going to be as lighter as possible up to the first red spots, but now I see it can be challenging for the camera.

No, raw zebras are broken in crop mood unless you use framing.
RGB zebras work but clip before raw.... so raw histogram is the best tool to avoid clipping.

You should get the same results in any ML build or in native Canon video modes in crop mood build (by turning off crop mood module), that's how Canon designed its LiveView,
because Canon real-time preview doesn't represet how actual RAW data look like, it's lossy and it does throw some of the RAW image info

Yes is not related with the latest crop mood but the ML iso negative gain in image fine tuning has changed. I was not able to achieve a darker image on previous version.
It shoul be related with what you have changed with aewb.

I agree that real-time preview doesn't represet exactly how actual RAW data look like (e.g. DR). But with other cams which shoot raw, liveview looks the same that raw data, maybe not with all dynamic range but with the correct average exposure.
The probleme here is that the liveview is a little bit to bright compare with raw data.
By additing negative gain in liveview, the exposure in liveview is more close to what raw data really look like.

ML falsecolor relies on whatever preview is active either Framing or Real-Time.

That's why I try to reach the same level of brightness and constrast on realtime than framing. And with negative iso gain that I can add now in liveview it's really close.

We all have experimented some raw shootings which looked quite good on the camera screen but actualy were too darkand too noizy.
That's because the exposure in liveview is not accurate. I know that we have to focus on the Histogram and try to expose to the right.
But if it is quite simple for a landscape to adjuste the highlights on the sky it makes no sens on an inside scene without hightlights or in a low key scene.

That's why false colors are useful to expose correctly our scene especially with skin tones.
The problem is that falsecolors are accurate in greyscale liveview  but not in realtime preview!
I did some tests and try to match liveview and greyscale by modified picture style and ML digital ISO.


By using Cinestyle picture style with contrast - 1 and ML digital ISO gain + 1.0EV in 12 bits (by using +1 it becomes in fact a little bit darker) I achieve something very similar.


                               
False color in realtime preview:                                                                  



False color in greyscale preview:




And it also match better whith raw datas

Realtime preview: 



MLV APP :                                                                                                                                                                                                     



MLV APP -1.0 exposure:



ADOBE CAMERA RAW DNG:




I cheked in photoshop with a spot exposure and I obtain on the TRex skin 52% of grey level which fits with falsecolors middle grey (between 45 and 55 percent exposure).

It's even not related to magic lantern. Right bouton (no need to hold it 2 secs) toogle between aperture and shutter. Next time we have to read the canon Manual  ;D

Done :)

Just to make sure, could you record a video shows how this option work? Is it the same as "Magic Zoom V2" in my old builds?



Yes it is. I was talking about Magic zoom V2 in your old build.

How can I enable RAW Zebras? I don't use this option, but I can check it.


Actually it works, it shows raw zebras but it's not localited in the good area it's shift on left. but we can use other zebras and it works very well even it clips before raw.


This build is fantastic !
#9
It is fantastic! Almost perfect.

What are missing in my opinion?

- as already said for the M custom buttons are missing.
- Before we were able to use x3 zoom even when recording it was a really good option even better than x10 zoom too blury for me.
- real 24.00 FPS
- realtime preview in 3k mode or almost realtime preview ;) but not necessary because 2880 are almot the same résolution.

- raw zébras don't work well but it 's not necessary too.

- it's stlll Eos M and 5d mark iii are still much better ;) and I hope for a 3.5 1:1 and 5.7k 1:3 realtime preview ;)
#10
Done!

My little contribution to your amazing work. You saved our money by avoiding to buy a new cam ;)
Thank you!

Limited FRTP in 3K preset is possible, currently it would be limited to 2868 width and the remaining 204 pixels will be black.

Before you will find a new magic trick... and I'm sure you will ;) I wonder if the missing data is necessary on the right part of the screen or if it can also be on the left part and if they are a way to switch between the two screens each frame or toggling with info button.

I see, well, it won't be real 24.000 FPS, but it will be in 24.00X to 24.0XX range depending on the preset (more accurately, on FPS Timers).

Thank you. The closest is better than nothing.

Actually, real 24 FPS can be done easily, would you even notice the diffrence?

Yes it's usefull for making a DCP or when we mix rushes from another camera in 24fps with 23.976 fps without sound shift.

In the next episode  :)

The 5d3 in comparison is really, really big and heavy. Still I hope now, that also 5d3 will get improovements.

Yes it's bigger and heavier but it's still a light cam if we compare to an Arri ;) But it's more stable than the M depending of your configuration.
#15
Awesome! Now it's just perfect ! Is it the last update? :D Only minor  improvements could be done in the futur: real 24 FPS instead of 23.976, 280 MHz overclock, FRTP in 3k mode etc..
#16
You just have to enable card spanning in raw options.
But for 5.7k anamorphic, card spanning is not
necessary except if the scene is too bright or overexposed.

@Grognard it is because with full frame mode you are using pixel binning (for example 1:3 mode) where the information from three pixels averaged in one, so less noise.


OK I understand what you mean. Thanks.
But I use to shot in fullhd pixel binning with my 5D mark iii and i've never noticed less noise in video (with pixel bining) than in photo (5.7k full sensor).
I will make some tests.

Quote from: mlrocks on March 11, 2023, 05:57:00 AM
Full frame mode has two stops better low light performance, and has much better shallow dof, tonality, gradation, color, dr, etc, due to 2.5 times larger sensor size.

What do you mean by two stops better low Light performance ?
Sensor is still the same. 3,5k is just a crop in the same sensor size so it should receive exactly the same amound of light.
3.5k with 1.6 crop factor is close to super 35 cinema so it's also a good choice.

Thank you Danne for the super grey fast preview. I could achieved this moving footages (backward travelling with gimbal)  without issues with the best ugly preview we have at the moment  ;)

I've read a lot about ML, I'm now addicted! I watched a two year old video saying it can only do 3 or 4 fps on 5.7k is this still the case?

I think it's 7.4 fps in 5.7k mode. But continuous with much less. I did'nt tried since a long time.

And what will be the point of using dual iso, if you expose so the highlights are not clipping with iso 800?

Iso 100 to expose the highlights I guess.
#22
Quote from: Mattia on March 08, 2023, 10:20:11 PM


The only thing that didn't work were the highlights in the dual iso shots which were flickering a lot. Do you know what could cause this?

Don't use dualiso anymore and prefere use lights inside and reflectors outside. Now, a decent lighting material is cheap.

I really hope I can get something on 5D3 regarding preview this year . .


Thank you for your amazing work!
I have both EOS M and 5D3, improvement for 700d /Eos M is a good news but improvement for 5d3 will be a little revolution because 5D3 is far better in terme of quality. It will not only be a cheap camera to achieve raw footages but a real cinematique camera for professionnal work.

When someone is wrong on the internet     :P

2 years ago, I unfortunately shot an entire day with 12 bit lossless, not to my knowledge, I had been messing around with slow mo and bits and forgot to reset it to 14 bit lossless..

....

I recommend you stick to 14 bit, unless you are okey with losing close to a stop of usable dynamic range.

2 years ago... maybe you're issue is solved now.

I use a lot of 12 bits without issues. You can see on my shots that i don't have any dynamic range issue.

The only problem could be on liveview when recording in 12 bits it's a little bit darker with a green cast on the screen.

In crop mode, ETTR histogram also doesn't work so well, maybe highlights were clipped on your shots.

I record in 14-bit lossless or in normal FullHD in uncompressed14 bit, to keep the best amount of colour.

With my experience there are no signifiant differences between 12 and 14 bits even in very complexe scene.

I'm always using 12 bits in 3,5k mode because is continuous (almost in 14 bits)


I used to shot in 14 bits uncompressed when lossless and 12 bits doenst existe yet but lossless is one of the best improvement.
