Yes, there is a preset in crop module for 1824x904 at 48 fps (which can be used to record 1824x776 resolution, which can be set in raw video menu)

It’s under the 720p presets and must be used with the camera set in 720p video mode in Canon menu. These high fps modes won’t work in normal 1080p mode, camera freezes and you need to do a battery pull ;)

Edit:
Not sure if this works, but to prevent switching between canon 720/1080 p modes, you could try to use 1824x904@48fps preset in 720p mode (with aspect ratio set to desired 2:35 in raw video menu to get 1824x776)
Once you want 24fps, try using fps override to see if you can get 24 fps instead of 48 fps.
Fps override is easy to switch on an off to get 24 or 48 fps.

Hi Levas, thank you so much I will try that out and let you know, that would indeed make switching really quick if it works! Thanks  :) :) :)

Hi again, OK I couldn't wait to test this so just have but I'm now struggling to get even 24fps... it seems to set itself to 17.521fps.. it also seems to limit the resolution some times to 1824*466 then other times its 1832*780 (0.99x)..seems to almost change every time I turn the camera on! It also pops up right at the start saying FPS override 48fps (great) but then after a second it goes to 17fps in the top info bar in live view and the live view freezes ... menus/ML menu still work fine though.

What I did was:

Put 6D in movie mode set to 1280*720
In ML press Q on "crop mode," went to "720p Preset" and set it to 1824*904@48fps
Turned "crop mode" on and chose "High fps only use in 720p mode"
In RAW video chose 2:35 (also tried 16:9 but FPS is still 17fps) and the highest it'll set resolution to by choose 1920.

Not tried actual filming or anything yet just wondered if you had any thoughts, or if you could try it your end and see if its the same, I am using the most up to date version of your build (jul2020)

Thanks!

Hi guys!

Been a long time Eos M user, and have moved to the 6d. Loving it, but just a little question.

I read that I could shoot continuous raw at 1876 3:2 with 90mb/s sandisk extreme pro, which I have. However, wether SDS module is on or off, I can only get about 7-8 seconds. Is this normal?

Would love some help with this. Thank you for all your work.

AJ

Is there a way to add "image effects" ? I want to preview negative films while digitizing them. thanks. Or is there a tone-inverting picture style available?

thanks

Hello.  I have been trying to find 6D update version 1.1.6.  The below link is not working;

https://web.archive.org/web/pel.hu/down/eos6d-v116-win.zip

Anyone know of a source?

Thanks

Link is ok. Problem must be on your side.

The original Canon firmware updater file for Canon 6D to version 1.1.6
Uploaded it to my google drive(long time ago). Contains the original .FIR file and some instructions PDF files in different languages:

Hello
I have a small question:

I'm looking for either 6D or 5D3
The problem is that i can get two 6Ds for the price of a single 5D3

I have a 700D (bilal's crop rec) and i'm looking for a full frame camera

How well does it compare? i would use mostly for photos (at least 5000x3200 and some video using 1x3 modes)

For video you're way better of with the 5d3
5d3 has faster write speed to storage card and sensor read out is faster (which gives you higher resolutions at the same frame rate compared to 6d).

For photo's probably not much of a difference.

Concerning Magic lantern, 5d3 has bigger userbase / more developers and is therefore more updated compared to 6d.

With that card I would expect higher speeds possible. I have a 128GB Sandisk 170mb card and it does around ~80Mb/s with the 240Mhz option setting.

But at what resolution setting are you recording, you might be in a video mode that is not data heavy. Normal 1824x1026 video mode doesn't need more speed then ~60Mb/s. So could be that your card can handle more, but your resolution setting doesn't require more speed.

Hello, I’m new in this forum and I like to share my test using the last build magiclantern-Nightly.2020Jul16.6D116 with the SanDisk SDXC Extreme Pro 64 GB 95Mb/s recommended. I hope this can be helpful.
I named the settings for practical purposes

Settings A (240Mhz)
SD: Sandisk Extreme pro 64gb 95mb/s
RES: 1824x1024
AR: 16:9
Frame rate:24 fps ALL-I
Data format: 14 bit (uncompressed)
SD OVERCLOCK: 240 Mhz
CONTINUOUS RECORDING
With this overclock when is selected RAW VIDEO shows me this before playback
74.8Mb/s 73x3.1MB, 23.970/982p Expect 2417-10000 frames at 78.8Mb/s

Using this configuration I can continuously record with no problem at any light situation but after I playback the videos something weird happen. If I try to record again suddenly stops recording after a few seconds, then I go back and see the settings and show me this:
74.8Mb/s 73x3.1MB, 23.970/982p Expect 322-505 frames at 62.9Mb/s
until I restart the camera it solves the problem. But when I use the SD OVERLOCK at 192 Mhz this happen…

Settings B (192Mhz)
SD: Sandisk Extreme pro 64gb 95mb/s
RES: 1824x1024
AR: 16:9
Frame rate:24 fps ALL-I
Data format: 14 bit (uncompressed)
SD OVERCLOCK: 192 Mhz

I can playback and record without any problem but it is no longer continuously record. It’s about 1 min 10 sec of recording.

Other test results with different bit rate and Overclock
SD: Sandisk Extreme pro 64gb 95mb/s
RES: 1824x1024
AR: 16:9
Frame rate:24 fps ALL-I
Data format: 12 bit | 10 bit (uncompressed)
SD overclock: 192 Mhz | 240 Mhz

Even if I restar the camera after changing every setting, I can’t playback the videos with 12 bit uncompressed and 10 bit uncompressed, only black frames are played, but when I transfer to the computer I can see it and edit. I will not use it because for me it is important to preview the video and be sure it is ok. With the 14 bit, 14 bit lossess, 12 bit lossess and 11-8 bit lossess there is no problem with the playback.

In conclusion

SETTINGS A (240Mhz)
-I can record continuously at any Bit rate, but when I playback the videos I can’t no longer record and I have to restart the camera to solved it.
-This configuration gives me more image quality.
-12 bit and 10 bit (UNCOMPRESSED CAN’T PLAYBACK)

SETTINGS B (192Mhz)
-Playback and record with no problems but less recording time depending of the bit rate used.
-This configuration gives me less image quality, a little of aliasing.
-12 bit and 10 bit (UNCOMPRESSED CAN’T PLAYBACK)

Notes:
-In the SETTING A (240Mhz) after playback, when I record and automatically stops recording the flushing buffer remains a longer time. (Maybe the problem is after the playback can’t reset the memory and for that reason can only record a few frames.)
-In playback mode, when I select the videos with compression (14 ,12, 11-8) appear the same info. It shows “14 bpp LJ92” in each video with different bit rate.
-When I change the SD OVERCLOCK and restart the camera, do not update the frames that it can capture until start the first recording, after that it showns the real frames can be recorded. (Maybe this module have problems updating)
-I also use another SD card Lexar Professional SD 633x 128GB SDXC UHS-I 95Mb/s but the performance is inferior compare to the sandisk.

I will use the SETTINGS A (240Mhz) for a while and let you know for the results. And hope could be a fix whit recording after the playback in the future.

Thank you Levas for helping us with your hard work.

Yes, but the 5d3 is not as good as the 6D in low light...

By the way, is it a big work to modify the ML intervalometer so that it could allow shooting at 1/10s step, instead of 1s step ?

All the best
