You can use mlvfs but you need a newer version with support for lossless compression.

This version was working for me 2 years ago:
https://bitbucket.org/ArcziPL/downloads/downloads/mlvfs_x86_x64.zip

Hmm, 160MHz preset jumping back to 20MB/s can be reproduced with my card as well... Just randomly, in benchmark in MV1080. Maybe it's possible to find a more stable 160MHz preset. I wonder why I was able to record hours with exactly (? there was one parameter more in a1ex code) these registers' values with the build from 2019. Needs some debugging. Don't hold your breath, no time at the moment.

We've all had best experience with SanDisk Extreme Pro "170 MB/s version" so far. If you want trying higher speeds, grab such one. Be careful, stick to reliable sources to avoid fake cards.

My loose thoughts (but I don't have much experience in low-light video, I'm definitely avoiding it...):
- don't increase brightness in post, i.e. expose well to the right, leave dark areas dark
- even if you have low-light conditions, use light sources of daylight color temperature (~5500K) or accept a yellowish look of your video. You'll get a lot of noise by using warm light and adjusting white-balance in post (because it will mean increasing brightness of a very noisy blue channel and also under-exposing the most important green channel).

Thanks! I confirm the 160MHz to not work on my 70D with SanDisk ExtremePro 64GB 95MB/s.

The sd_uhs module in 2021Mar01 build is directly the module from this topic from theBilalFakhouri, which is tailored for 700D. I did a bad job not testing the 160MHz preset with 70D at all. I checked only the new ones: 192 and 250MHz, confirming both working with SanDisk ExtremePro "170MB/s" and only 192MHz working with the older "95MB/s" version of the card. Benchmarks shown similar results like vastunghia reported above. I don't know how stable they are during recording, as I don't use my 70D anymore. Would be nice if also others could report about the stability!

Great that Bilal published his code, so I could prepare a build with his great code as base but with registers of 160MHz preset reverted to

Code Select Expand

static uint32_t sdr_160MHz[] = {0x2, 0x3, 0x1, 0x1D000001, 0x0, 0x100, 0x100, 0x100, 0x1 };   /* overclocked values: 160MHz = 96*(4+1)/(2?+1) (found by brute-forcing) */


Here the new sd_uhs module only:
https://bitbucket.org/ArcziPL/downloads/downloads/sd_uhs.mo

And here a full vanilla ML build with this module already included. The rest stays untouched from 1mar21:
https://bitbucket.org/ArcziPL/downloads/downloads/magiclantern-Nightly.2021Apr04.70D112_crop_rec_4k_mlv_lite_lossless_fps_override_focus_stack_sduhs.zip

Thanks for testing and reporting!

Do you really have the 95MB/s version like on the photo on Amazon? So far it was reported, that only the newer one, labeled with 170MB/s, works with the 240MHz preset. And my 95 and 170 follow this rule. But it could be batch dependent.

My 700D was "different" but same as Bilal's. I never managed to make it "normal", even via restoring camera defaults.

My 70D switches between being "different" and "normal". I have noted down the relative difference of the offset.

I would like to know if it is already possible to record full hd or near full hd continuous raw. I saw that it has 10/12/14 bit but stopped at maximum 20 seconds even using U3 card.

Use Sandisk Extreme PRO 170MB/s card and enable sd_uhs module, then set overclocking to 192 or 240MHz in the Debug tab. It will improve the write speeds.

4 - Which firmware should I use?

Canon firmware v1.1.2 and I believe this ML version: https://www.magiclantern.fm/forum/index.php?topic=25786.msg213074#msg213074

It's a pity I missed THIS 2 years ago but a1ex is right: focus stacking & related features do work on the lua_fix branch for 70D, just need to be enabled.

Better late than never but this cam really deserves more love and a better maintainer (porting crop_rec presets...).

Please read first post in this topic for more info. Also here the download link:

https://bitbucket.org/ArcziPL/downloads/downloads/magiclantern-Nightly.2021Mar01.70D112_crop_rec_4k_mlv_lite_lossless_fps_override_focus_stack_sduhs.zip



I reverted also the FRAME_SHUTTER_BLANKING_* addresses to the standard from 4k_crop_rec branch because I don't know what I'm doing here and how to test. Further read on this feature: https://www.magiclantern.fm/forum/index.php?topic=14309.msg213436#msg213436

Confirmed: 70D can do 240MHz as well.



The card was Sandisk Extreme PRO 170MB/s 64GB.
With the older 95MB/s version of the card the 192MHz preset works well (results like on 700D) but the 240MHz falls back to 20MB/s.

Thumbs up Bilal! Great achievement!

[ExecuteEventProcedure]

I have analyzed how the ExecuteEventProcedure function calls functions by name and I have found the location where names and function pointers are stored. Thus I was able to dump

Isnt't this an amazing breakthrough in scope of whole ML (and maybe all cams)? For me it sounds like (but I'm a noob here)! Congratulations!

Damn, I'll miss you a lot. All the best to you and I hope to not miss any of your future works. Your presence here gave a feeling of being somehow closer related than just seeing postings Youtube.


BTW: this is impressive!

Yep, it exists! Thanks!

GUI_SetIsoSettingStep Value(%d)

List of not working features of the "original" nigtly build:

https://www.magiclantern.fm/forum/index.php?topic=14309.0#post_notworking


My custom build has additionally added lossless compression of RAW video (thanks to a1ex help) and disabled FEATURE_ARROW_SHORTCUTS, which was buggy:
https://www.magiclantern.fm/forum/index.php?topic=25786.0

And some days later FPS override was activated (thanks to findings of David_Hugh) which is having a small glitch but is usable
https://www.magiclantern.fm/forum/index.php?topic=25786.msg213467#msg213467

There are no crop_rec presets available. It's doable but no time here.

15 March is like 7 March but additionally the FPS override function is available (usable but with a small glitch).

Does anyone have an idea if there is a function to change ISO selection steps from 1/3EV to 1EV? On 70D it's an option in Canon menu but it's not present on M50.

I personally find the 1/3EV steps a disadvantage. They make changing ISO with the dial way too slow for my taste and it's just a digital push/pull which can be done in post.

Greg, maybe you have digged in this direction already?

Script for M50 v1.1.0 is:

Code Select Expand


private sub Initialize()
    ExportToEventProcedure("GUI_SetSilentShutter", 0xe0536113)
    GUI_SetSilentShutter(1)
end sub


It works, thank you! This feature is fantastic!

Thanks Greg for finding this function and trying out.

Thanks! I'm on 1.1.0, so need the new adress first (and add +1, for setting the THUMB flag).

Sounds cool!

Will it be as simple as this?

Code Select Expand


private sub Initialize()
GUI_SetSilentShutter(1)
end sub


Cool, you do really nice stuff. Thanks for sharing it! I'm also impressed by the power of LUA implementation in ML. Amazing.

theBilalFakhouri have you already tried finding a way to enable the 3x3 binning on 700D?

Great work theBilalFakhouri!

Maybe it is time to make a PCB board for this? I only used one resister instead of four.

Unfortunately, I have no idea about CF and no time to go into the topic, but just quickly checked the pins with pull-ups.

https://www.syslogic.de/ProductDocuments/deu/Product-Manual---503-CF.pdf

-PDIAG
(True IDE Mode)
In the True IDE Mode, this input/output is the Pass Diagnostic signal
in the Master/Slave handshake protocol.

Others (/WE, /CS1, /DMACK) should be plain inputs. Try at least to add a second, separate resistor for PDIAG. No idea what and when this pin does, if it's used in both directions in True IDE (sorry, really no time) but as a quick check it might be worth trying...

Hopefully they can somehow fix the overheating through an update or something, otherwise they're fried! 😉

There is a hope at least for filming with EF-mount lenses.
