Sounds like you need to engage the overclocking.
- Select ML raw video modules, sd_uhs, and crop (the crop was disabled but I selected it anyways ... superstitious) 
- Select ML raw resoultion 2560 at 2.35.1 aspect, with framing
- in  ML turn global off
- in ML, Sd overclock at 160 MB/s, need to override the warning
- go back check your resolution message, it should be green (or flicker from red to green, I did not always see solid green)
If not reselect the overclock,
- In liveview, on Q menu select 24 fps, ensure AF is not set to facial tracking, I suggest single box
- In liveview, on what is by default the * button on back hit until 5X
- Press liveview, and it may go red, yellow, green, but after about 30s the red disappears.

When you are pre-focus the half-shutter press effects focus/liveview update (play with it)

Hope this helps

It appears I'm Already doing My SetUp the same as Yours,, Except > I'm unclear on the meaning of this >
 
"- in ML, Sd overclock at 160 MB/s, need to override the warning

I don't get any visual indication that SD O'C' is active > 41MB/s is indicated Upper Right during Rec.

I have tried activating SD O'C' both Manually & via AutoRun ~

[ShootMeAlready]

Its the same issue as in « Reply #3356 on: May 15, 2019, 12:09:01 PM »

I found the override in two places, in ML menu, there is in Video Menu and again in the Overview of settings menu (on top far right, scroll down).  Sd module has to be loaded, as well as ML raw modules.

Try clean reboot, set-up, then press it once, exit ML, then 5X/AF and record. That's what I generally did.

"I found the override in two places" > Are You now Calling SD OverClock "the override" or are You now referring to something else?

In My ML Menus there is no reference to SD O'C' in the Video Menu & I do not have an "Overview of settings menu". The Far Right

menu on All My Cams is named "Modified" & SD O'C' does Not appear in that menu ~ To the immediate Left of that menu is a menu

named "Recent" & SD O'C' does appear in that Menu & when that SD O'C' is clicked it does appear to activate the O'C' & subsequent

Rec's of 2560x1090 2.35.1 23.9p 12bit raw lossless in 5X can be acquired Continuous ~

[ShootMeAlready]

As was said in previous reply you can read literal message, but it asks you more or less are you nuts for doing this? (russian roulette with your data)  Then you click - yes, to override. But you are running an experimental build anyways, and your camera came back from the dead so you are fearless.  You should only need to do this once per boot-up.

[ShootMeAlready]

i dont think you can shoot 60fps in 5X mode. no matter whatever your setting is in canon menu when u zoom in 5X it wil change to 30fps

I was able in 5X to shoot 24 fps.  I was testing 1920x1080 12 bit lossless in 5X, but 5X initially selected goes to 30 fps,
but if you set fps override Timer A to 842 (+170) I was getting 23.9 fps.

I could turn global on, with half shutter press, then set fps override to 23.9 and timer A to +170, and get 24 fps.
Global on you get screen updates every 3s or so.  In camera video playback is slow.  The big problem now is in camera liveview and playback. 

However with 5X cant get higher than 30p.   It would be interesting to compare 70D 12bit raw to 80D H264, to see how 80D sensor DR stacks up.

I suppose to answer my own question,
70D 12 bit raw if shot 1/3 over (expose to right) then it should have better detail. 
80D probably less noise in low light without processing. 
However detail can be traded off, to yield less noise, so it probably is a very fair comparison in the hands of skilled shooter.
I suspect 70D wins via better highlight and overall detail but low light noise about equal for same ISO.   Now for someone to check it out.
The 80D probably wins for high ISO shooting (ISO 3200 in H264) as raw tends to max out around ISO 800 (before hot pixels kick in).

got a 5d mark III yesterday. i may soon say goodbye to my 70D

Hey ML community.
It's been a while since I lurked on here and I'm trying to understand exactly what everyone is talking about to update myself. Search didn't resolve my confusion, apologies if I missed it clearly laid out, but if someone has a moment would you mind updating me on the 2.5k / fps / 5x mode recording capabilities in a nutshell?

From what I gather, changing between 14 / 12 / 10 - bit allows recording up to 2.5k resolution, but the camera has to be in the 5x screen zoom / focus check mode?
So the actual recording is not cropped to 5x, but without an external monitor you will be viewing your live preview at 5x zoom?

Sorry for the bother, just trying to get myself updated on the latest ML abilities for the 70D.
Much appreciated!

[Walter Schulz]

Actually crop mode is 3x and you get same cropped frames everywhere: recorded data, liveview monitor and HDMI.

[ShootMeAlready]

Ok 5X mode on 70D, is like a magic zoom. You see 5X on live view, but the actual video is 3X, so its a wider frame on playback.
Not sure about HDMI out? Its been a while.
I think I recall you get all the LCD output, with the magic lantern screen stuff (as I recall). 
The HDMI out always required no screen extras, and then you could output to a video recorder.
At 5X and 2.5k @ 2.35:1 24fps, the LCD updates with a lag. So I suspect there's a lag.

[andy kh]

with the HDMi you wil only real time preiview in 5X crop mode. in camera you can choose between framing and real time

[dfort]

Got some requests to put up a 70D build with lossless compression. I'm getting this when compiling the current crop_rec_4k branch:

Code: [Select]

#error FIXME: please define FRAME_SHUTTER_BLANKING_READ
I can either back out the changes that require FRAME_SHUTTER_BLANKING to create a hacked build or if someone with a 70D that knows how to use adtg_gui could look up ADTG registers 805f and 8061 we can do something a little better. Ideally these addresses eventually won't be hard coded.

[Danne]

Think these will work:

Code: [Select]

#define FRAME_SHUTTER_BLANKING_ZOOM   (*(uint16_t*)0x404e6180) // ADTG register 805f
#define FRAME_SHUTTER_BLANKING_NOZOOM (*(uint16_t*)0x404e6184) // ADTG register 8061

#define FRAME_SHUTTER_BLANKING_READ   (lv_dispsize > 1 ? FRAME_SHUTTER_BLANKING_NOZOOM : FRAME_SHUTTER_BLANKING_ZOOM)
#define FRAME_SHUTTER_BLANKING_WRITE  (lv_dispsize > 1 ? &FRAME_SHUTTER_BLANKING_ZOOM : &FRAME_SHUTTER_BLANKING_NOZOOM)
Arcipl got them from his camera. Don´t remember where to find them but look around. He has his code on bitbucket.

[dfort]

Thanks. Looks like @ArcziPL has a test build on his downloads page. He did some tests on it so I think it is best if I just redirect any requests for 70D builds.

Would be nice to see a pull request for this.

[ArcziPL]

Think these will work:

Disclaimer: no idea if the addresses of frame shutter blanking times are constant or camera-dependent or maybe even random at power-up. I also didn't test them as I didn't know how.

[baladev]

Not sure if this is still relevant. I've just finished smoking the thread to educate myself about nuances of running ML on my recently acquired 70D. I've come across mentioned a couple of times people having difficulty running SD OverClock module on ArcziPL's builds. I also experienced this - the module giving me malloc errors when trying to run it. In my case it gives the error if Raw video is on. If I turn it off, I can enable overclock and then turn Raw video on.

I also did some quick tests today comparing different sd_uhs modules and it seems the one included is slower than Danne's. I will do more tests to confirm this.

Hey guys, big ups to everyone getting lossless / sd hacks / 3k going on this cam!

I've been checking this thread fairly regularly since it started, and reread the last 5 pages, + searched the 10bit thread,  but still a couple of things I can't find info on.

1. Why does 14bit lossless say ISO < 100. To me that means choose an ISO smaller than 100, but that doesn't make sense. Why does ISO matter to lossless anyway?
2. Magenta highlights in 12bit /10bit lossless modes. Is this a known issue? What causes it? I remember reading somewhere way back about incorrect white level, I can alleviate it somewhat by messing with it in MLV App, but I've no idea what I'm doing and it seems to hurt other colors. What's needed to fix this on the 70d now and can I help?

thanks

Is it ok to use this installation method :  https://www.dpreview.com/forums/thread/3628812?page=3       ?
I had the same problem. It took me a while to figure out that there are two ways to install dual iso. The second option is downloading another software called Eoscard. It makes any SD or CF card bootable. I took the second option. The steps are as follows:
1. Download Eoscard from here.
2. Unzip it.
3. Download the nightly build (ML and autoexe.bin files) and unzip it. Transfer both files (ML and autoexe.bin) to the root of the memory card (already formatted in camera).
4. Click on Eoscard (memory card still connected to computer). Its interface will open and it will immediately recognize the memory card. Screenshot of the interface is here.
http://chdk.wikia.com/wiki/EOScard
Make sure that only Bootdisk is checked as in the screenshot. Click Refresh. That's it, your memory card is now bootable. You won't have to go through firmware update process. Take the card out of your computer and put it in the camera. You are good to go.

And what should I use - last nightly build or archive from the start msg of this topic? I mean:
nikfreak-magic-lantern-0e6493e8ac5e.zip
or
magiclantern-Nightly.2018Dec24.70D112.zip
It seems that the second one is newer (2018-04-30 vs 2018-12-24)

tnx ahead

PS hmm.. may be from here? But which archive should I use?
https://bitbucket.org/ArcziPL/magic-lantern/downloads/
Looks like @ArcziPL has a test build on his downloads page

[Walter Schulz]

Today EOScard's role is mostly reduced to unbrick (semi)-bricked cams after panicking owners formatted their cards prematurely.

Go to top of page -> Downloads -> Download nightly builds
and follow installation instructions.

Hey guys, long time on and off lurker here looking to finally get back into ML and raw after like 8 years ago.

First off: I've read all post a year back, but I'm not a techie and this is all a bit difficult for me to comprehend.

Trying to decide between a 70D and an EOS-M. Found amazing info about the M since there seems to have a very dedicated following who are really pushing the limits. But not so much love for the 70D.

Obvious differences are of course form factor, articulating screen and DPAF, but how "stable" is ML on the 70D compared to M? From what I've read displaying crop mode is a bit wonky compared to mcm rewire on the M.

I already have a couple of EF(s) lenses from my old camera, so the more expensive 70D would be the same as the M + new lenses and adapters. I'm not a slow motion guy, 30 for 24 fps for slight over cranking is all. But I do longer takes (5-10 min) and like to move the camera and getting more into dynamic blocking and would like DPAF since it's usually myself and manual focus is just one thing to many.

I guess what I like to know are the top 5 reasons to go with the 70D and the top 5 things you wish you knew before buying the camera.

All the best!

[ShootMeAlready]

5 Reasons to use a 70D
- DPAF tracking is required, fast moving objects that you want to track in mostly centre of screen.
- pull focus off the screen, natural speed
- Use the LCD not the viewfinder for menu & touch focus
- Great stills camera and you already have quality Canon mount glass

Video
Well here's where things get really interesting
Its H264 All-I is good to ISO 1600 but the 80D has a better sensor for DR
Lots of free picture profiles for 70D, some even shoot flaat, all good for H264
Anti-aliasing at 3X, with MF (mostly).  This mode requires noise reduction and grading in post (IMHE). 
MLRAW video : APS-C so its 1.6X compared to FF, you may have some quality DSLR glass
- you can shoot 14bit ML raw FHD with MF
- you can shoot 12/10 bit raw most resolutions up to 2.5k at 2:39 24fps, but its MF
- Max AF resolution is around 90% of FHD, 2:39 at 24fps (10/12/14 bit). So with AF you would always need to up-res. for FHD.
- Any resolutions higher than about 90% of FHD, with LCD live-view tracking is zoomed, it shows 3X on LCD, of a 5X frame captured.  So its not the ideal FHD to 2.5k live-view. 
- 720p raw works 24/30 fps 10-14bit, with many ML goodies.
- 60p is only 720p, H264.

Sorry I dont know the M-series, so compare against this general profile.

[Ingerson]

thanks ShootMeAlready! I got an M, but don't really like the ergonomics, miss my 1000D I have for stills, haha. Gonna see if I can find a good deal on a 70D

[andy kh]

Im a 70d owner and i would highly suggest you not to buy 70D if you already own a M.

[Ingerson]

care to elaborate? I got a cheap M, but miss the DSLR form factor and would like better AF since I'm a single shooter coming from street photography.

af is really good. i also bought one because of this feature. there are some ML features missing in this camera. i dont kno if those missing features are important to you or not  and i get some terrible moire and aliasing. i am not sure if its because of the lens i use which is tamron 17-50mm f2.8 non VC
