Scripting Q&A / Is there any way to automatically load the ADTG config？

« on: April 28, 2021, 04:50:22 PM »

Is there a way to automatically load the ADTG config？For example, automatic loading is done through Lua scripts.Turning off the ADTG gain via ADTG registers to get the lowest ISO for shooting is very helpful for my older camera. It would be even better if it could configure it with a one-click load via a script. I hope to get some ideas to achieve purpose. Or has anyone tried?

General Help Q&A / Cr2hdr export picture unexplained picture resolution reduced

« on: October 03, 2020, 05:33:27 AM »

The other day, I took some dual ISO photos using the officially compiled atest Lua updates + fixes 500D firmware.
When I try to export using cr2hdr, I find that the DNG resolution after export is only 384x252

This is my log

General Help Q&A / On the 500D 10 bit RAW video bad frames

« on: June 08, 2020, 02:52:59 PM »

When playing back 10bit raw video on a computer, most of the frames were wrong, as if the frames had been torn apart, sometimes with color bars.
I tried to use FPS override with different frame rate, but the question remains





I don't know why
But I didn't have this problem when I was recording 10bit RAW video in X5 mode.
My camera is 500D
Using the firmware is according to the https://bitbucket.org/hudson/magic-lantern/branch/raw_video_10bit_12bit_LVState compiled firmware https://github.com/wanghurui/hello_world/releases/download/ML/magiclantern-Nightly.2020May25.500D111.zip

Thanks

General Help Q&A / Semi-automatic mode for video？

« on: March 26, 2020, 07:07:19 AM »

Does the magic lantern have a semi-automatic mode for shooting videos, such as fixed shutter speed, auto aperture, and ISO, fixed aperture, auto shutter speed and ISO? Like the Av, Tv mode。
