Reverse Engineering / HDMI reverse engineering

Topic split from TFT SIO communication (

I run "Brute-force all registres" on 5D3 v123 with HDMI monitor. No registrer change view on monitor (as could be expected).

Is it possible prepare some brute-force test for registeres that could be change view on HDMI monitor?

I am looking for some alternative for magic-zoom on HDMI monitor
(e. g. "Scroll" HDMI output:

Feature Requests / ND filter instead reflex mirror
« on: April 30, 2017, 02:25:22 PM »
Camera EOS C300 has three internal ND filters:

ND 0.6 – 2-stop reduction
ND 1.2 – 4-stop reduction
ND 1.8 – 6-stop reduction

This is better than screw and unscrew ND Variable filter on lens after each change of luminance (filming in the dark church/sunny garden before church).

I use my 5D Mark III mainly on video. Why not use dark ND filter instead reflex mirror?  8)

Would be possible control reflex mirror in video mode? (flip-up/flip-down)

If yes - some company could be create ND filter (like "Mosaic Opto-Electronics, Inc." creates VAF filters)  :)

Reflex mirror replacement should be relatively easy:

Feature Requests / Zip RAW video

Space is very limited when I record to RAW video.
Zip archivator runable after record (from menu) will be great :)

Feature Requests / "Scroll" HDMI output
« on: December 29, 2016, 12:42:07 AM »
Many HDMI monitors have 1:1 view (pixel per pixel) but most of them can display only center of view. Scroll display is not possible.

Is it possible add feature "Shift HDMI output" to "Arrow/SET shortcuts" for display optional part of view in center of HDMI output?

80D shifting the display buffer (from Twitter by a1ex ?):

Feature Requests / 4K video in 1:1 (

Is it possible change position of crop mode for every second frame (as HDR video)?

In post processing:
left and righ frames could be converted to one panorama.

Feature Requests / H.264 picture style HDR

Is it possible change Picture Style for every second frame (as HDR video)?

In post processing:
light and dark picture styles could be converted to file with 14bit depth.

Feature Requests / Waveform in wide mode
« on: February 27, 2016, 04:54:12 PM »
Can you add wide waveform view like Cineroid EVF has?
( : style 1)

It will be much more usable for me.

( Note: FullScreen waveform is cropped on 5d mark II; Nightly.2015Nov07.5D2212 )

Feature Requests / AWB without shift
« on: February 27, 2016, 04:27:55 PM »
When I shoot a documentary video I sometimes mistakenly turn on "Adjusting white balance...".
This set wrong "White balance" and "WB Shift". When I switch to AWB by Canon menu (for fast fix) the "WB shift" is still wrong.

Is it possible:

1. turn on "Adjusting white balance..." by longer way for prevention
(e. g. by holding RATE button - similary as open ML menu by holding arrow button; or by double-click),

2. reset "WB shift" after set AWB?

Feature Requests / Rack Focus cycle
« on: July 19, 2014, 05:20:15 PM »
Please, can you add the choice of never-ending cycle to Rack Focus? I need it to make timelapse with large aperture.

There is some example:
(1/13 F13.4 ISO3200 f300; MLV video)

The building is not in focus. ISO is in limits of usability. I had to make a compromise. If I set longer exposure, Moon woud be blur...

Rack Focus cycle is solution for me: focus to building / focus to Moon / focus to building / ...
(+ join couple of images in postproduction)

Feature Requests / Turn off LCD and LV after 0sec
« on: August 18, 2013, 12:49:27 AM »
I have 5D2 with CF Transcend UDMA7 600x 32GB. When I shoot RAW video in 1856x1044 24fps with configuration "Global Draw off" and "Turn off  LCD and LV" after 5sec ("Enable power savin: on Recording") I have about 800-1200 images. I think if the configure "Turn off  LCD and LV" could be set to "after 0sec" (unsupported value) the number of images will be higher. Yes - I can not see LCD display when I shooting but number of shots is more importantly for me...
