Quote from: a.sintes on April 15, 2024, 12:22:24 PMTHERE IS a realtime liveview during anamorphic/crop mode (some people are actually using it via HDMI to deal with focus while recording), just not the one you're expecting as it's the Canon-native 1080p hardware one when you'd prefer a replication of the ML software based framed preview (yes, the grayscaled half-resolution, doing its best fps-wise) which is actually displayed as a replacement of the hardware one, dealing properly with crop modes and anamorphic features by design.

There's currently no such thing for the 5D3 as in Bilal's crop mood for EOS-M that tweaks directly the hardware liveview, solving then both LV and HDMI displays at the same time (which will be the best solution, let's continue to hope Bilal will unlock it one day).

I tried to overwrite the current HDMI output with the framed-preview buffer but I currently get synchronisation issues and/or crashes so I give up, maybe I'll try again later.
Anyway I will prefer to solve this better than rely on an USB stream.

I tried your new builds running ultra-fast code for the live view, much credit to you sir! Definatly a massive step forward and actually makes it usable :)

Does anyone know why 12bit lossless recording doesnt seem to be possible in increased resolution modes? Would be helpful to allow continous recording is 2.39:1 on CF only. The current 1808x2268 14bit lossless is so close to be continous on CF only when im using Dual ISO. Can currently get a few minutes. Using Lexar 128GB 1066x cards.

Also on another note, USB liveview works (Albeit the bottom 1/3 of the image missing), but it slows down the camera too much, as soon as you start recording it fails. Id say USB liveview while recording is not an option.

Thanks! if you mean getting real-time preview for custom high resolution presets on 6D:

6D is more similar to 5D3 and 70D (all of them have DIGIC 5+ SoC), current preview work (in crop mood) does only work on 650D / 700D / EOS M / EOS M2 / 100D (DIGIC 5, without plus) and this due to some differences among DIGIC 5 and DIGIC 5+ families, hence we will need to reverse engineer LiveView on DIGIC 5+ mostly from scratch, and currently I am still in the beginning phase.

I have both 5D3 and 70D, any progress on one of these model will mostly translate to the other two models, if I could achieve something on 5D3, it willl mostly be just matter of copy paste to 6D (due to similarities).
Unfortunately, no one can predict when we will get something working on 5D3, it may take months / years or may not happen at all, so I can't promise anything, but I can say that I am currently working on it.

Hey Bilal, just wanted to check in with you if there was anything you might need help with? I am not a programmer, but I do own a 5D III if you needed me to test anything etc.

Apologies all for the misunderstandings, I'll have a look at the information :)

Has anyone tried USB video feed while recording in the 1808x2300 anamorphic mode?
#5
Have you tried the anamorphic 3x3 Dannes build? There is no realtime liveview in this mode. Only grayscale at perhaps half fps. I'm pretty sure HDMI output is the same view as the screen on cam.

I'm well aware HDMI has liveview, but we are talking about while using and recording with this particular build.

Quote from: Walter Schulz on April 15, 2024, 08:20:16 AMOnly a very small set of Canon gear actually has UVC on board: R50, R8, R10, R6 Mark II, PowerShot V10.
Canon USB inside 5D3 is not UVC but proprietary handled by PC tools like EOS Webcam Utility, EOS Utility, SparkoCam, gphoto2, etc. and some smartphone apps.

That said: You can stream via USB or HDMI. HDMI requires an HDMI capture device (most are actually UVC).
Out-of-the-box 5D3 does true FHD over HDMI. No sound.
Resolutions: 576p for USB, 1080i with HDMI.

And no audio via USB/HDMI for 5D3 (and other Digic 4 and 5 cameras).

The purpose is to get liveview in Dannes Build. Apologies when I say UVC, I mean the version of UVC which the 5D III has, which can be used vai certain camera control apps. HDMI doesn't have realtime liveview when recording in this build, but figured the USB video would be worth a shot to see what the liveview is like? Has anyone tried the USB video feed while recording in Dannes anamorphic mode? What is liveview like? I just tried to to a test on my PC through the canon apl, but my mini USB cable is broken :(

Hi all, keen to be more involed with this project. Btw guys, 1808x2300(2:35.1) @ 100/800 HDR - Truly gives some amazing images. Practically no aliasing due to the squeezed recording method being implemented. 1 thought, is it possible to perhaps use the USB webcam feature to get a video feed of the image, while internally recording? It then may be possible to use a mobile phone vai UVC to have a picture. Thoughts? Ill test it out tonight to check the video feed over UVC.

Hi guys, avid user of Magic lantern, and recently got some EF anamorphic lenses.
Anybody know if its possible to get a 6:5, 3:2 or 4:3 image with the 3x3 sampling method?

After some extensive tests using this build, I am finding using this 3x3 sampling method combined with Dual ISO removes most if not all visable aliasing.
Because of this, Im keen to see if the method could be used to create a 6:5, 3:2 or 4:3 output instead of the current 16:9, 2.35:1 and 2.39:1 options.


Any thoughts, would be very much appreciated!

Will it be possible for resolutions above 2k to have working full live view (other than 5x)? Or is it a hardware limitation?

Thanks heaps.

Hi all, sorry for the misinformation A1ex is correct and was wrong about the compression :/
Gets so confusing lossy and lossless haha

12bit lossless is beast!

To answer "whysodifficult"'s question about 10bit,12bit,14bit.


14-bit - No edit to the original Canon 14bit Raw File
12-bit - Is 4 LSB Trimmed (nearly lossless - Almost identical to 14bit visually)
10-bit - Is 8 LSB Trimmed (Small loss of detail in shadows - Still Visually similar to 12bit Overall)
14-bit / 12 / 10 lossless - Bitdepth changes with each type but is Losslessly compressed. This Means there is almost no difference between compressed and not compressed, this is because the compression is Lossless. Lossless compression tries to eliminate data that is not visually useful, therefore visually it is the same.
But because Higher ISO's generate more noise this makes it more difficult for the lossless compression method to work.

14bit Losssless Compression - Only works with 100iso or lower. Works well with LiveView but the only limitation is its pretty much locked at ISO100 but you get 14bit RAW :)

12bit lossless Compression - 100iso to 1600iso - This is my preferred Shooting mode as i almost never go above 1600iso, and at lower ISO's 100-800 Compression is usually always more than 50% which is great for longer shoots.

11bit / 10bit / 8bit - This is variable based on the ISO you are using. 11bit up to 1600iso, 10bit up to 6400iso (i think?).

So all in all this latest branch of Compressed RAW is great for reducing file sizes (in camera) without any visual loss.
Or if your keen to try, (14-12bit-10bit lossless) enables higher resolutions at 24p-30p such as 2.5k 3k 4k.

I think pretty soon a close to 3k 16:9 option should be included as a easy setting for continous shooting :)

I am so impressed with the development of magic lantern throughout my short span of using it its truly amazing, and the devs are doing such an amazing job!!! Magic lantern is so so so so good, and now with 10bit 50p 1080P continuous and stable? Its literally a dream come true!

I have installed the module and so far so good on 5D III, makes 50p 1080p (vertical upscaled 1.67x) continuous from what i can test.
Although as some other people have pointed out crop mode in 1080p 50p doesnt work as half the
frame is cut off top and bottom (image here: https://drive.google.com/open?id=0B1q4BC6n6pcNVTBwcUNXamRTRmc

Main Q:
But i was just wondering if anybody know the difference in dynamic range from 10bit to 12bit to 14bit?
From what i can see there is slightly less dynamic range every step down from 14bit, biggest difference i think is from 12bit to 10bit....
It is my understanding 14bit 1080p raw is around 11.8-11.5 stops?  :'(
Is 10bit something like 10 stops?

I might want to add that i use RawFlow to extract my files and 10bit extracts fine without any issues i can see.
Link: https://www.magiclantern.fm/forum/index.php?topic=13338.0
Its by far the easiest way i have found to extract files without any complications, and the images that get extracted are amazing!

Thanks Guys
