ISOless 8 & 15 Dual ISO fix (https://www.magiclantern.fm/forum/index.php?topic=7139.msg197139#msg197139).

ISOless PH err(2) prevails. Anything I can contribute to nail it?

Hey Walter.
There is problem with shutter speed for 1440p and higher resolution.
Its standard 29.98fps that make its hard to record due high frames, i set to 24fps override and the shutter speeds go to 1/250 or higher.
That would really be nice to get that fix.
I dont have this issue with EOS M running Dannes Build or with Billal custombuild of Dannes 100D branch he did for 650D that iam running, the only thing that dont work is the buttons zoom and info etc
.

Reproduced the error on 700D:

It seems getting the right addresses aren't enough on your 650D, so you need to tweak these too in dual_iso.c:

Code: [Select]
        FRAME_CMOS_ISO_SIZE  =       0x22;

        PHOTO_CMOS_ISO_SIZE  =       0x10;

Error happens but it's err(8 ) now!
This result looks promising, let's try again:

1-Grab this adtg_gui.mo (https://drive.google.com/file/d/1QfBQkORaKQ-cT9-Y4QOm-mpsHhecFOmm/view?usp=sharing), should work on crop_rec_4k builds, you can try on my latest build for 650D too.
2-Set ISO to 100, Let's start from video mode, set FPS override to 12 FPS to achieve more speed when enabling the module.
3-Load only adtg_gui.mo module, restart the camera, enable the module, Highlight "ADTG Registers" then press Q button, highlight CMOS 0, you need to get the address, write it down.
4-Switch to Photo mode, none-LiveView, take a picture, write down the new address from CMOS 0.

Redo the steps from 2 to 4, but this time Set ISO to 200.

This is the part containing the address we need in the white box:

Provide the new addresses for ISO 100 and 200 for both photo mode and video mode, let me check them . .

Refer to issue #1781 (https://foss.heptapod.net/magic-lantern/magic-lantern/-/issues/1781).

Hardcoding addresses is simply *not* going to work on 650D, 700D and maybe other models. It may fix the problem for some cases (possibly depending on what camera mode is used at startup, or other settings, or simply because of the multitasking startup process used by Canon) and will fail otherwise. The address you are looking for is allocated dynamically, so one has to find a pointer to it somewhere in a RAM dump - that pointer is likely at some fixed address, regardless of the exact startup sequence.

Suggested approach:
- find a few cameras / startup configurations that result in different CMOS[0] addresses (at the very least 2, but I'd recommend 3 or more)
- hardcode the address from adtg_gui and confirm it's actually working reliably (predictably, deterministically) on each of those cameras and/or configurations
- get a RAM dump from each of those cameras and/or configurations
- annotate each RAM dump with the address that was confirmed to work
- blindly scan for a pointer to that address (the CMOS[0] address will be specific to each RAM dump, but the pointer address should be the same in all dumps)

I will follow a1ex suggestion in the future, this may take a while, not sure when . . my experience with finding stubs or addresses in ROM dumps wasn't very successful, didn't look at RAM dump before . .

So for now I can help with a temporary solution for Walter's 650D, hardcoded values for his camera.

@theBilalFakhouri: For 700D I found your focus pixel maps and added them to the MLVApp repos. This has the advantage, the latest MLVApp versions (inofficial) are able to auto download the maps, if MLVApp loads the clip. Do you also have the maps for 650D? If you have, let me know, I can add them to the repos. Or we add you as contributor to our repos for such uploads! :)

Hello @masc

Yeah I have noticed that, it was quick, for 650D it *might* be identical focus maps to 700D maps, but with 650D ID in maps naming . . Not quite sure yet I don't have clips from 650D to check . . I will try to get some clips.
I have no reason to refuse your offer, that would be cool :)

I’m new here. 650D/t4i user - been searching through the posts looking for the right settings in ML to get the 29:59 restart to work correctly.  I have the LUA build running with firmware version 1.04.  I’ve gotten the Movie Tweaks, Movie Restart set to “On”.   Everything else having to do with Auto Shut-Off is turned off.  Also, I am NOT recording, but using my camera as a webcam.   I have the camera on movie mode, with a direct power source, and it is shooting in Manual Mode. 

I’m sure there is something I am overlooking.  Thanks for responding.  I do ASL Interpreting (now from home) and I really want to utilize my completely capable DSLR to get a clear pic.

Provide the new addresses for ISO 100 and 200 for both photo mode and video mode, let me check them

I got some notes regarding ISOless error (2).

Whenever I get this error the address (for both photo and video modes) is always shifted exactly by 0x100: https://imgur.com/a/2Uw6Sra.

I can confirm that workaround suggested by linuxhenhao (https://foss.heptapod.net/magic-lantern/magic-lantern/-/issues/1781#note_129528) six years ago still works.
I compiled mentioned workaround based on Bilal's build (https://www.magiclantern.fm/forum/index.php?topic=5951.msg231434#msg231434) for 650D and 700D. I can't tell if this works on any other model, but so far it works consistently on 650D: https://mega.nz/folder/CvY2DJZL#wBCp4bONkizG_e2a8qeoIQ

Hey all.

I cannot seem to get focus peaking to work with an external HDMI.
The resolution captured by my capture card is 1080p.
It keeps drawing in the middle only. See below.

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fi.ibb.co%2F61PrndD%2Ffocuspeak1.png&hash=d0560fc9d4151fead3e75f8e9dfd50fc)

If I change the recording resolution down to 720p, it seems to work.

(https://www.magiclantern.fm/forum/proxy.php?request=https%3A%2F%2Fi.ibb.co%2Fs27nt41%2Fimage.png&hash=4b0979fa13f72d7d0f8b3a83d6f999f0)

Focus Peaking works perfectly fine in 1080p on the build-in LCD.
I've noticed that the spot metering location is also offset when displaying over HDMI in 1080p.

I'm running the build posted above, crop_4k 2020Sep30.

I have loaded modules:
+bench,
+crop_rec
+mlv_lite
+mlv_snd
+pic_view
+sd_uhs > 160MHz

NOW in Overlay > Global Draw i set LiveView and i am able to run mlv_rec without errors on screen (because of "LiveView") when turning on the camera.
Shutter error 1/25 still occurs sometimes. The above modules load almost correctly but the clips recorded by mlv_rec have no sound.

Hello. The other day I switched to this firmware on my 650d. Very pleased! But unfortunately I encountered the following problem:
When I rotate the wheel to adjust the shutter speed, it is always the same. So visually the light on the picture changes, and the value remains the same as on the attached screenshot. :-[

Hi @Icaab

This issue affects some 650D models, Your camera have different "Shutter Blanking" addresses, current solution to hardcode your camera's shutter blanking addresses in the source code, and compile the build.

I may do it in the future (Compile and Upload two 650D builds), but currently I don't have time.

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.

Hello, everybody. I’m worried about the following things in this firmware:

In Crop-Mode 2 mode, my screen is compressed and it is difficult to display the composition.
When I connect to a device via hdmi, I get an image of poor quality and an incorrect number of frames.
Besides if I connect the device to the camera via hdmi and include mode 4.3k in Crop-mode 1 - I have the hanged image on the connected device.

Can it all be fixed now or expected in the future? Maybe the ADTG module can help, but I haven’t found an up-to-date version of it.

Hello, everybody. I’m worried about the following things in this firmware:

In Crop-Mode 2 mode, my screen is compressed and it is difficult to display the composition.

Hello Icaab,

Crop mode V2 doesn't have any preview fixes, you need to use ML Preview a.k.a "ML Framing" when using this module.

When I connect to a device via hdmi, I get an image of poor quality and an incorrect number of frames.

HDMI output isn't recommended when using crop mode modules like crop_rec and crop_new, what do you mean by incorrect number of frames?

Poor quality image? HDMI output already have poor image quality, could share a picture showing what you outputting on the HDMI device.

Besides if I connect the device to the camera via hdmi and include mode 4.3k in Crop-mode 1 - I have the hanged image on the connected device.

Again, attaching HDMI device isn't recommended with crop mode modules, these modules works better on LCD screen, for the hanged image when using HDMI device you need to do these to make it work:

1- Make sure the output is 1080i, other outputs won't work resulting in frozen preview.
2- You need to use Full Canon preview (toggle with Info button).

If it still doesn't work, report back, show me your camera settings, output signal, Canon preview.

Can it all be fixed now or expected in the future? Maybe the ADTG module can help, but I haven’t found an up-to-date version of it.

HDMI output is low priority for developers, most users don't use it too because of bottleneck, corrupted frames and some bugs (even with official ML builds), but enhancing real-time preview in general I guess it would get some attention in future for some developers, currently I am not active regarding developments. ML currently doesn't follow a schedule, so nothing can happen now.

ADTG module won't work with crop mode modules at the same time when both are activated, preview registers are many (https://www.magiclantern.fm/forum/index.php?topic=25287.msg230520#msg230520), it's hard to tweak them one by one and without having pre-calculated values (https://www.magiclantern.fm/forum/index.php?topic=25287.msg230520#msg230520).

Technically, it might be possible to get 30 FPS in all 1x3 presets in Crop mode v1 (crop_rec) also in 1920x1280p 1:1, but didn't try to do it, because these presets won't have continuous recording @ 30 FPS. But might add it in future, because . . why not.

Hi!

I had the same behaviour when using focus peaking with HDMI output, this problem not related to my build exclusively, and it might be fixable, but needs some debugging. Sorry I don't use HDMI and focus peaking much . .

Could it make sense to use the sd_uhs module to activate a continuous record at 30 fps?

Post by: theBilalFakhouri on April 18, 2021, 09:03:36 PM
Increasing FPS would decrease write speed performance in LiveView, SD Overclock and 10-bit lossless would help, but it's unlikely to have continuous recording.

E.g:

4.3K 1x3: 1440x1836 @ 30 FPS in 10-bit lossless --> ~66 MB/s
UHD 1x3:  1280x2160 @ 30 FPS in 10-bit lossless --> ~69 MB/s

In normal 1080p @ 24 FPS 3x3 I can get maximum write speed of ~68 MB/s, @ 30 FPS it drops to ~64 MB/s and both have been tested with the 240MHz overclock, anyway let's wait for the real results when 30 FPS get implemented.

Okay @Icaab I have made some tests:

30 FPS with real-time correct preview presets won't be possible, the sensor is capable but there is an overflow or something like that resulting in corrupted frames.

For example, Some months ago I made a preset 1736x868 (2:1 AR) @ 50 FPS in 3x3 with real-time correct preview, but when attempting to record (or when transferring the data from the buffer to the SD card) the LiveView becomes choppy, and the frames get corrupted, and this because of the real-time preview, a lot of data is being processed in LiveView --> more memory is used --> I think some memory overlapping is happening .. or maybe it's simply a bottleneck

We need to make further research regarding LiveView and Buffer (memory). The help of Lead developers are needed, they are not active currently . .

I might lock this thread, and let the discussion continue on this thread (https://www.magiclantern.fm/forum/index.php?topic=25784.msg231049#msg231049) since 650D/700D are very similar, we might re-name that thread to include 650D too in the title, I don't want to duplicate the posts in two threads, this doesn't make sense . . No need for two threads . .

Good day! I want to ask the professionals. One of the programs was so that it destroyed the memory card when switching to a photo or so. Is there any sequence of actions in the new version of November 2020, or will it not kill the memory card anymore? Thanks in advance for your answers. Thank you!

Добрый день!  Хочу спросить профессионалов. Одна из программ было так что уничтожала карту памяти, при переключении на фото или около того. В новой версии от ноября 2020 есть какая то последовательность действий, или это уже не убьет карту памяти? Заранее благодарен за ответы. Спасибо!

Unclear description and question. Please clarify:
You got one of your cards killed?

Yes, crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Jun30.650D104 killed the controller on the memory card. I later read one in the forum, some people had this. To take a photo, you need to turn off all modules and reboot the camera. I found out later. If not, the card controller burns out.

Да, crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Jun30.650D104 убила контроллер на карте памяти. Я потом в форуме в одном прочитал, у некоторых людей такое было. Что бы снимать фото, надо выключить все модули и перегрузить камеру. Я это потом узнал. Если не сделать, контроллер карты сгорает.

Hi Saint

This "crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Jun30.650D104" build doesn't belong to this thread, but that's not the case right now, so you maybe are talking about SD Overlcocking (sd_uhs.mo)?

I later read one in the forum, some people had this. To take a photo, you need to turn off all modules and reboot the camera. I found out later. If not, the card controller burns out.

Had what?
if they can turn off all modules so they can use ML, which loaded from the SD card which mean the SD Card works, and SD controller can read the content of the SD card which mean also the SD controller works.

There is a case If you take a Photo when crop_rec module is on, your camera will lock up and you need to pull the battery out, that's not related to SD controller and SD card.
So let's not mix the things togather.

Now we need more details from you:

What's your SD card name and specs?
Does your *burned* Card works in a card reader using a PC?

Put another working SD card in camera, without Magic Lantern installed (if previously Installed Magic Lantern, format the card in PC first), can you a record H.264 video or a take Photo?

Thanks for the answer! It was last year. SD was killed this 100%. Since I understand a little about administration and hardware. It was changed under warranty. SanDisk Extreme Pro 95 MB / s. I installed the firmware, tried to shoot a video. I even took it off. Was glad. Then I switched to the photo, I wanted to take a frame for the white balance. The device is frozen. I took out the battery, but he never came back to life. I decided that the camera had died. Then he pulled out the card, without the card the camera came to life. But the card was dead. I saw a USB device but no more.

Спасибо за ответ! Это было в прошлом году. SD была убита это 100%. Так как я разбираюсь немного в администрировании и железе.  Её поменяли по гарантии. SanDisk Extreme Pro 95 MB/s.  Я установил прошивку, попытался снять видео. Даже снял. Был рад. Потом переключил на фото, хотел сделать кадр для баланса белого. Аппарат завис. Я вытащил батарею, но к жизни он не вернулся. Решил что умер фотоаппарат. Потом вытащил карту, без карты фотоопарат ожил. Но карта была мертвая. Виделось USB устройство но не более.

Communicated with a person, he had the same thing. And he said that in order to switch to the photo shooting mode, he turned off all the modules, then his photo worked and the camera did not freeze. to shoot a video, he again loaded the modules and filmed. The only way. And he, too, like me, for the first time, the controller on the card burned out. Not in the camera. I don't know English well, so I write through a translator.
Thanks for the answer!

Общался с человеком, у него было тоже самое. И он сказал что для того что бы переключится в режим съемки фото, он отключал все модули, тогда у него фото работало и камера не зависала. что бы снимать видео он снова загружал модули и снимал. Только так. И у него тоже как и у меня первый раз сгорел контроллер на карте. Не в фотоаппарате. Я плохо знаю английский, поэтому пишу через переводчик.
Спасибо за ответ!

Okay the SD card reader in camera is working fine.


So your *dead* SD card isn't showing in PC using a card reader?
If that true, this mostly mean your SD card is dead, I wanted to suggest formatting it with this tool:
https://www.sdcard.org/downloads/formatter/

But since the SD Card isn't showing in PC, that tool might not help you.
Have tried another SD card reader?


The only reason your SD card would die in camera when using ML might be from using SD Overclocking module (sd_uhs.mo).
sd_uhs.mo module is experimental, there is one guy had a dead SD card after he used sd_uhs.mo
 (https://www.magiclantern.fm/forum/index.php?topic=12862.msg199429#msg199429)
You didn't confirm if SD Overclocking was ON or not . . in addition I am not really familiar with Danne builds like "crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Jun30.650D104", so not quite sure what might be going in the build, but for other users the build was fine.

Also, I don't know what settings you are using . . I can't really help you, you may want to ask Danne, or record a video showing your camera settings and what are you doing, do this at your own risk.

I realized it was a year ago, maybe the overclocking module was turned on, otherwise I would not have installed the firmware. I put it stable and use it. I wanted to know if your firmware could have such problems with the memory card or if it is more reliable than the one I wrote about. Thanks again for the great answers!

я понял, это было год назад, возможно модуль разгона был включен, иначе бы я не стал ставить прошивку. я поставил стабильную и пользуюсь ей.  я хотел узнать, на ваших прошивках могут быть такие проблемы с картой памяти или она более надежная чем та про кторую я написал. Спасибо еще раз за большие ответы!

In my build, originally SD Overlocking isn't loaded, you need to load it manually then activate it. All others modules in my build are working in this way too.
For me, never experienced in burned/broken card, I have both Sandisk Extreme PRO UHS-I U3 95MB/s and 170MB/s versions, but this isn't a guarantee

Also, crop_rec module won't be patched in Photo module to avoid camera lock ups when taking still pictures in Photo mode.

If you don't want to use SD Overclocking or crop_rec (mostly crop_rec needs sd_uhs activated for continuous RAW recording), you can use the official ML builds from here:
Builds under "4K raw video recording; lossless compression" are pretty stable
https://builds.magiclantern.fm/experiments.html

If you are not a video shooter, you may want to use other builds, like lua_fix builds, or Nightly builds (https://builds.magiclantern.fm/).

However, if you need an extra features, mostly for RAW video, my builds are pretty good too, and very similar to the official ML builds but with more features, and don't forget my builds contains bleeding-edge stuff (very experimental) compared to ML official builds:

Dear Bilal!
Yes, I use my camera at home and only shoot videos, sometimes photos.
I want to try your build, do I understand correctly that without the card overclocking module I will not be able to shoot RAW continuously?
Can you give me a link where is the best and the best module that will not break my SD card :-)?
What lenses do you use for crop mode so that the angle is not narrow?
As always, very grateful for your answers! Thank you!


Уважаемый Билал!
Да, я использую камеру для дома и только снимаю видео, иногда фото.
Хочу попробовать вашу сборку, я правильно понимаю что без модуля разгона карты я не смогу снимать RAW непрерывно?
Может дадите ссылку где самый лучший и хороший модуль который не сломает мне карту SD:-)?
А какие обьективы вы используете для crop режима, что бы не узкий был угол?
Как всегда очень благодарен за ваши ответы! Спасибо!

Hello again!

You can shoot RAW video continuously in normal 1080p mode without the SD Overclock (at 14-bitdepth or lower in lossless compression), but if you want to use crop_rec module (Crop mode) which has 1x3 presets and others which require high write speed, you will need to enable SD Overclocking to get continuous RAW recording, you can install my build and start experimenting with RAW video recording in normal 1080p mode then maybe try crop modes, without the SD Overclock to get an idea about what you will get.

Current state of SD Overclocking module is experimental (in all builds), and could be dangerous for SD Cards also for the card reader in camera, currently there is no way to use SD Overclocking safely, as I said it's experimental, don't use if you can't deal with data loss, or burned card!

However, only few cases have been reported for a broken SD card when SD overclocking was used (2 or 3 people), most people didn't have any problem with SD Overclocking, and they are using it everyday, this isn't an advice or a guarantee, just saying. You can start without SD Overclocking and you should be fine, if you want to use SD Overclocking again, use at your own risk!

For the lenses, I mostly use the Canon kit lens 18-55mm 3.5-5.6 STM, also I have 10-18mm 4.5-5.6 STM lens, fortunately 1x3 modes doesn't have too much crop, so the 18mm focal length might work fine for you.

In 1:1 crop modes, I mostly would prefer the 10mm focal length, in the end that's all depending on what kind of shot you want.

Also, if decided to use my build, please read all the instructions carefully in first post (https://www.magiclantern.fm/forum/index.php?topic=25784.msg231049#msg231049) of that thread, feel free to ask questions.

You're welcome!
