LE simulation via Bracketing, using shutterless, Full Res Silent Picture
Creates brackets for post processing a simulated LE exposure
User must set FRSP mode, ie DNG or MLV and also wheather to use Dual-ISO
Exposure Sim should be on
Should be in LV
Version 0.8: Requires the Lua Fix

I mean when I use 5d3 anamorphic mode, I can go iso 6400, in 3.5k 1x1 mode, I can go iso 1600.

OK. I tried again now with this approach.
First, card spanning off, sd card overclocking off, 1080p 60 fps preset, red, about 9 seconds, stopped automatically, no error message
Second, card spanning on, sd card overclocking off, 1080p 60 fps preset, red, about 5 seconds, stopped automatically, no error message
Third, card spanning on, sd card overclocking on 160 mhz (needs sd card reformat and camera restart), 1080p 60 fps preset, red, about 3 seconds, stopped automatically, error message window out.
Allocated 105 slots
Fail info: (16382 16382 6501 3693) (127 151 182)
Then rolling like
Overexposure fix
Black 5/5: stdev too large
Black 4/5: stdev too large
Black 3/5: stdev too large

Testing if grayscale framing preview could get even faster
Quote from: vastunghia on February 01, 2023, 07:06:52 AM
You are breaking my heart here
Why is everybody so in love with the M? A 2nd hand 5D3 is not as cheap as an M, but it is very close and so cheap in absolute terms anyway. And is by far superior, technically speaking (starting from e write speed capability of course).
So really, a genuine question, can somebody explain to me why M is so popular?
Quote from: vastunghia on December 06, 2022, 07:52:52 AMThe settings preview > frozen LV only works before recording, so it's not possible to disable while recording but:
Ps: holy grail for me would be to have dark LCD screen when no button pushed and framing preview when half shutter pressed. But I guess this is more complicated. Or could this be achieved with Lua?
menu.set("Overlay", "Global Draw", "OFF")
menu.set("Overlay", "Global Draw", "ON, all modes")

So the question -- finally -- is: Would it be possible to reverse this behavior? So have a new option in ML making it possible to have
- Global Draw = off (or maybe even better, no preview at all on cam, as I will be looking at the external HDMI image) all the time,
- Global Draw = on (correct preview) only when you half-press shutter?
Would be so sweet if it turned out to be a simple mod in the code...
console.hide()
mod_button_1 = KEY.Q -- Switch Preview
function test41(key)
if key == mod_button_1 and lv.enabled == true and menu.visible == false then
elseif menu.get("RAW video", "Preview", "") ~= "Framing" then
menu.set("RAW video", "Crop rec preview", "OFF")
menu.set("RAW video", "Preview", "Framing")
return false
elseif menu.get("RAW video", "Preview", "") == "Framing" then
menu.set("RAW video", "Crop rec preview", "OFF")
menu.set("RAW video", "Preview", "Real-time")
return false
end
event.keypress = test41

Your CF is the issue. 12 bits is continuous and 14 bits "almost" in every situation sometimes it could stop but is rare.
Quote from: ilia3101 on May 28, 2022, 08:55:34 PM
With these new hacks + overclocking + card spanning, 5D3.113 gives 3840x1536 14 bit semi-continously
Previously I could only get 12 bit for no more than 10 seconds.
I can't thank you enough!
