We can get 8K@120FPS. It will work like 4K in M6II - M6II vs M50 4K

« on: May 24, 2020, 09:39:43 PM »Is this based on the infamous "fishy" build?I don't have the "fishy" build code. This is digic6-dumper branch and stubs, consts, button codes, several modifications (bmp_vram, disabled audio tasks etc).
You can load "fishy" autoexec.bin in IDA/ghidra, convert the file M50_101.sym to idc script to name the functions.

The M50 sensor is too slow to do this. You need 2x more data to read a dual pixel. So maybe at 10-15 FPS?
At the current stage of development, we should not think about such advanced features.

Yes, each camera has a different x sync calibration. You can change this value, but I don't know where (prop/eeprom).
Proposed name for the module "fake_hss.mo"
A few years ago I used arduino as a shutter button. Arduino sent a signal to the camera (shutter release connector) and then to the radio triggers.
This may be somewhat unstable. In some modes, the camera has a random delay.
- Start FRSP @ F16
- set the aperture to F1.4
- trigger the flash
- set the aperture to F16

Was reading chdk's wiki last days and then shocked seeing they could do some kind of 1/60000 flash sync speed.It's possible for a CCD sensor.
this one I didn't understand.A1ex knows how to change the aperture during FRSP exposure. If you know how to trigger a flash at the right time. You can try :
- Start FRSP @ F16
- set the aperture to F1.4
- trigger the flash
- set the aperture to F16

You can try "leaf shutter" by changing the aperture value when capturing FRSP.

I compiled this code in digic6-dumper branch. This is not ML, but 2 features with which the M50 is more useful.

These few lines of code modify properties, unlock features that the M50 doesn't have in the Canon menu.

So RP and M50 still have only automatic electronic shutter mode?
I thought these few lines of code were not a problem for them.

EOS R (before/after)
Any tutorial how to remove that kind of banding? Or just dark frame substraction?Didn't the latest firmware for EOS R solve that?I don't know if I should publish this script, maybe I should sell it to Canon?

These histograms show dark frames (lens cap photography).
Look at the histogram and you'll see the missing bits. It looks like 12-bit converted to 14-bit.

M50 bit depth
Single - 14-bit
Continuous Low - 12-bit?
Continuous High - 12-bit?
Histograms (single, continuous low, continuous high) :
If you want to use 14-bit exposure bracketing, you need to quickly press the shutter button, continuous modes are not 14-bit.

« on: May 09, 2019, 02:15:38 AM »
If you remember which prop and you can load ML, you can try to create a minimal autoexec.bin which will try to restore this prop before err is initialized.
It worked on my 500D a few years ago.
If this does not work, you need to contact unbrick.io
