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

10/12-bit RAW video compiled on 500D 1.1.1.Experimental raw video recording at lower bit depths.
Download >>> https://github.com/wanghurui/hello_world/releases/download/ML/magiclantern-Nightly.2020May25.500D111.zip
I haven't tested for a long period of time.

Tested (Using a Lexar 2000x 32G Card)

• record 1584x404 10bit 23.976 FPS video continuously
• Record 4 seconds 2000x838 10bit 20FPS video mode in LV x5

I don't know why mlv_play can't play 10bit RAW video and show nothing.

Hope can have 10 bit / 12 bit raw plug-in

I tried to compile using https://bitbucket.org/hudson/magic-lantern/branch/raw_video_10bit_12bit_LVState on my 500D with 1.1.1firmware, but it's not working.

I found some errors about module_strings.h while trying to compile the 500D firmware.
eg:

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。

 ;)Can 500D digital4's processor be used for sd card overclocking？

The RAW video really shocked me, but the device I used was 500d of the digtal4 processor, which can only record 3-5 seconds. I hope the sd card can be overclocking on the 500d. I can provide my device for the test.Thanks
