@srsa_4c your my hero! That worked like a charm on the LCD & via HDMI. Now I can use an Atomos or Blackmagic to record the output.  Next step for me is getting it hooked up to a keypress for toggling, which based on the sample scripts, should be pretty straight forward.  I'l post up my final results.

You help a lot of folks on this forum srsa_4c, big high five!

Can someone help me?  I stream and im currently trying to get CLEAN hdmi out on this camera.    i got CHDK installed 120f   and enable the LCD NEVER TURN OFF feature

Got most of the overlays off.  it looks good.    Only thing left is the face tracking box that wont go away.   i see this .Diff file and im at a wall.   How do i install  it?  I read that you cant use canon basic scripts with CHDK installed.  Which sucks because thats the only way i know how to do it.

What do i do with .diff?  how do i install it while retaining my ability to keep the lcd to never turn off (it cuts the hdmi feed if i do)

It's a source patch, meaning changes that need to be applied to the CHDK source before building.
Here's a build for M3 120F with the patch applied https://app.box.com/s/ck48h376sfcaxas3fxj5klveaufy4a79

Nice effort.  There are two things not quite right though.

First of all CHDK is not a firmware mod.  No changes are made to the firmware on your camera.  When you remove the CHDK enabled SD card, you are back to your original camera setup. That's actually a nice feature - no risk of bricking the camera like you get with firmware mods.*

Which brings us to the other issue. 

All those files you dragged onto the SD card early in the video?  They are specific to both the camera and firmware version. The files that work on one model's firmware version won't work on the same model camera with different firmware versions.  And they certainly won't work on other models.  So somewhere in your description you will probably need to explain how to figure out what firmware is in a camera and which files to use?

*EDIT: the point about CHDK not modifying your firmware is not just sematics. You will need to install it on every SD card that you want to use with disabled overlays. CHDK "goes away" every time you turn your camera off and has to be reloaded when you start again.  Fortunately, the steps you followed cause an automatic reload  :haha

The first patch has seen 40 downloads so far, which makes me think this feature is worth to add.
Attached is an updated patch, supporting the same features as the original.
Since the same code works on both m3 and m10, I moved the routines to core. I replaced the empty dialog based forced redraw with a different method (setting a palette related fw variable followed by a screen refresh). I can only test on my m10, and the new method seems to work (Canon drawings are removed properly). I believe it should work on the m3 also. If anyone with m3 could confirm, that would be useful.

I would like to check this in in a few days, if possible.

edit:
Added to trunk in changeset 5164. Added some usage notes to the camera-specific notes.txt files, so zip'd builds will contain some info.
