I wouldn't mind 1620x912 with black bars but it's stretched (more like squeezed from top to bottom) via HDMI which makes the LV via HDMI useless :/

Hey, when using rawVideo recording (3:2 aspects ratio at 1824x1216px 1.00x)  my 6D only outputs a stretched live view via HDMI, and it also looks far from 1824x1216px. More like below HD. (I don't have VGA 720p ennabled) Any suggestions?

I just realised that my Canon 6D (with latest 2020 ML build) can show the actual framing in crop mode when activating sticky half shutter.
On the Canon Display itself it works great, but when connecting a monitor via HDMI it only shows the normal cropped view, not the actual (half shutter) one.
How can I change this?  ???

Sorry for the late reply  :D
For raw recording you either use mlv_rec or mlv_lite, you can't use them both.
mlv_lite supports lossless compression, so use of mlv_lite is advised. So best to not enable mlv_rec module.
The 1x3 presets are not supersharp, the reason, the data is not saved as 5496x1960 but as 1832x1960 resolution. The sensor does horizontal pixelbinning, 3 pixels become one.
So the sensor does really readout 5496x1960 in pixels, but passes this data on as (5496/3 pixelbinning)= 1832 horizontal pixels x 1960 vertical pixels.
In post, for example in MLV_App, these 1832 horizontal pixels are stretched to the original 5496 pixels for normal aspect ratio.
So 1x3 is not as sharp as you would expect from the resulting resolution, because some trickery is used that is available at hardware level of the Canon camera.
In my experience the free software, DaVinci Resolve from Blackmagic does a really good job for upscaling video. (for free, download the normal version, the studio version is the paid one)
It's not that intuitive to use, but there are a lot of tutorials availabe on youtube.

Unfortunately, this is normal  :P 
I couldn't get normal liveview to work in this mode, you could however use ML preview to see what the recording will be like.
You can choose different preview options in the 'RAW video' submenu. It's on the MOVIE tab of Magic lantern menu, highlight the 'RAW video' option and press Q button on camera.
Now the 4th option from above should show Preview, here you can set the option from 'real-time' to 'framing', whith the option framing selected, you should see a low resolution preview of your liveview (it's a little slow in FPS).
Another option, you could switch to 'framing' by doing a half press on the shutter button, while doing half press, you should see a preview.
I like this option, I use the half press to check the framing, and press record button, you can even do half press of the shutter button while filming, to check the framing.

Thank you for the great informations! :)
I will stick to 2K resolution then :D
I will also give DavinciResolve a try!

2. Try "Topaz Video Enhance AI v2.0.0" for upscaling. But it takes a lot of time.
Thank you! Do you know if its using GPU to calculate? :)

Hello

1- 5496x1960 in 1x3 isn't real "5496x1960" it's actually 1832x1960 de-squeezeed to 5496x1960 to get a correct aspect ratio (that's how 1x3 mode works).

You should compare 1832x654 3x3 vs 1832x1960 (5496x1960 after correction) 1x3, now you would notice the more details in 1x3 mode (in addition to no aliasing, less moire).

1x3 mode is the sweet spot between 1:1 and 3x3, if you want the absolute sharpness you need to use 1:1 modes, cropping 1x3 footage in post isn't a good idea, it's more like cropping 1080p footage.

2- Upscale it directly from MLVApp --> in Export settings --> resize. You need to take care of aspect ratio, if you have exactly 2560x1440 MLV and you want to upscale it to UHD, set 3840x2160 in "resize" settings, But if you have for example 2560x1280 footage, and you want to upscale it to UHD, putting 3840x2160 in "resize" would result in correct width, but the height would be stretched from 1280 to fit 2160 resolution (Taller aspect ratio which isn't correct)

You need to calculate the AR manually 2560x1280 upscaled to UHD would be 3840x1920. Not sure why MLVApp doesn't calculate AR automatically, it isn't implemented.

3- Provide a picture how LiveView look like, give a short Sample MLV (you can shorten it in MLVApp from "Cut in & Cut out" tab, 2 frames is enough).

Thank you!  :D
I will try the Upscaling! Which would be the best codec option to export for best quality and for using it with Premiere Pro and Blender? Apple ProResHQ?

Here is a picture of the Display of My Canon 6D when trying to shoot at 4896x2160.
I photographed it with my smartphone if thats alright. :)

Hey! I am using a Canon 6D withe the latest build for it and I have a few questions:
1)  I tried to use the 1x3 preset "5496x1960". When reviewing it at home the video looks not sharp and kinda blurry. Any ideas why this happens?
2) When I shoot in 1x1 with 5x crop i can get a resolution of 2560x1440. I need to upscale this but which is the best way to do this?
3) When I am trying to shoot in 1x3 I can choose the preset "4896x2160" but then there are only magenta, pink lines across the Live View. Any ideas why?

Thanks for your help!

Hey there,

I updated to the latest build from here and when I start my 6D a message appears in the bottom screen saying:
"tcc: error: undefined symbol 'raw_force_aspect_ratio_1to1'
[E] failed to link modules
updating Movie Tweaks -> Movie Logging


I Can not load any modules, what is happening?

EDIT: when I turn off mlv_rec it does not show an error but this way I can not use RAW mode. What is the sollution to this?

Hey there.
I saw a video on youtube where the creator says he is using the build: magiclantern-Nightly.2020Jul16.6D116
But here on the forum I can't find anything newer then Nightly.2018Jul03.6D116.
Does someone here know where this build is hidden?

Update: Found it: https://webcache.googleusercontent.com/search?q=cache:TWJAaqGudUEJ:https://www.magiclantern.fm/forum/index.php%3Ftopic%3D15088.1250+&cd=2&hl=en&ct=clnk&gl=pl
