And nothing new?

Very good

Is it possible with 5D3? i see anamorphic 1920x2300 @24fps and 1920x3760 @15fps
My question about it from January 03, 2022:
https://www.magiclantern.fm/forum/index.php?topic=23041.msg237597#msg237597

Great build!

Everything working perfectly, did a bunch of tests, the idle/recording trick fixed all half-shutter problems

What's impressive is that with "Rec trigger: Start/Pause" while recording but paused (waiting half-shutter to start) the previews stays "idle" only changing when actually recording

That's great, pretty much real-time BW while recording

Helo, looking good!
(since we are talking about preview i feel like this might help)
I'm having problems, I guess is not ultrafast but half-shutter behavior , is there any setting or anything to do to avoid half-shutter to zoom? (perhaps somewhere codded)

Sometimes i use ("RAW video", "Rec trigger", "Half-shutter: start/pause") and i get stuck cropped preview, (3.3k/3.5k stuck cropped preview,anamorphic stuck cropped distorted preview,Full-res/UHD/4k stuck with no preview at all)

While playback:
Is it possible to disable automatically for a while?

Auto ETTR does not change aperture, but this script will take your ISO and change the aperture accordingly (-1 EV for +1 EV) same with shutter speed, FRSP has a shutter speed limit, so, why not compensate with aperture?

Original Timelapse script:

maybe you wanna tweak some lines? Here's some info:

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

same problem here, can you test with 1:1 1920? i cant go with iso much higher than that

In full resolution 1:1 its not continuous, you can make it continuous with 5fps (fps override)

Anamorphic mode is 1920x3400 or something, meanwhile 1:1 is something like 5700x3400
thats a 3700 pixels less than 1:1, so the speed require is lower


ps:
"If I want to change fps to 24 fps, 10 bit, 14 bit lossless, the camera freezes. I have to take out the battery. Seems the fps override does not work in this mode."
that happens to me too, perhaps in the future we might get full resolution anamorphic at 24fps

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

just tested here, same thing, about 10 seconds recording then console shows up with this same messages (btw, preset 1080p 40fps does the same thing)
I guess its not the speed since even 3.5K at +130mb/s is continuous

perhaps exposure?

I've seen some post about the amount of details of the scene, blurry (and slight out of focus) scenes requires less mb/s

Also, if the problem is the write speed then reducing 8-10 bit should be enough, but isn't

Sounds like a Hollywood movie trailer and I'm thrilled as f*. Keep up mate!

Man i was gonna say the same thing, i'm invested


Looking good @bilal, great job

That's impressive 😮

Testing if grayscale framing preview could get even faster

Very good update

Perhaps good news for 5D3? 😍

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?

Exactly, where i live theres not a single EOS M for sale, seriously, i was trying to find one

You are doing great with the 5D3, everyday feels better and better, been testing with my phone as a second monitor, 5D3 monitor as framing and phone as real-time (anamorphic stretched)

Hi Danne, is it possible to add

Code Select Expand

RAW_PREVIEW_GRAY_ULTRA_FAST
to the 1:1 crop modes? the BW preview in anamorphic modes is almost real-time

perhaps as a option on/off?

Thank you

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?

The settings preview > frozen LV only works before recording, so it's not possible to disable while recording but:

Prefs > Powersave in LiveView > "Enable while recording" and "Use shortcut key" should work

In lua is possible to:

Code Select Expand


menu.set("Overlay", "Global Draw", "OFF")
menu.set("Overlay", "Global Draw", "ON, all modes")

That code as half-shutter key, I had some freezes, most likely due to my lack of knowledge in scripting

[So the question -- finally -- is: Would it be possible to reverse this behavior?]

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...

I guess it's possible with lua script, i have set the Q button, while in LiveView to switch between Framing and Real-Time
That's actually a good idea and i might try change a little bit my script:

Code Select Expand


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


I'll do some tests later

So.. aparently Full Res silent pic don't work (the long exposure one)

If high iso and slow shutter speed: "Raw error"
Can someone confirm this?

Your CF is the issue. 12 bits is continuous and 14 bits "almost" in every situation sometimes it could stop but is rare.

What CF do you use?
I guess the SanDisk Extreme pro would be better, I'm just not sure how better would be, if it's just less than 10mb/s maybe it's not worth

Without card spanning I can get a bit higher cf speeds (85mb/s or something)

CF: 64gb SanDisk Extreme 120mb/s
SD: 64gb SanDisk Extreme Pro 170mb/s
Build: lastest anamorphic (with the lv hacks improvements)

I couldn't get anything higher than:
CF 70mb/s
SD 50mb/s
(Killing global draw)

I can't get 3.5k 14bit lossless or 12bit lossless continuous
10 bit is continuous, manually stopped 4 minutes later (118mb/s)

I can't copy the files right now, I'll do later


Many people are getting higher speeds, guess my CF is too slow

You can use Fps Override with the low light setting (rather than high fps)
I can get continuous at 5fps and card spanning

I also made a lua script with some settings that i mostly use (1080p, full-res with half shutter, 3.5k, and  burst 5fps by holding half shutter)
I can share that script if you want to

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!

I'm sorry being a bit off topic but i have a question

i'm trying with overclocking, these new hacks, card spanning, killing global draw,and i cannot get 14 bit for more than 3 secs (3.5K preset, 24fps)
The scene is exposed to the right, Raw module says 168mb/s required (lossless)

Is it better underexposing by 1 or 2 stops or stick with 10bit properly exposed to the right?

I'll 3 scenes from yesterday:

Hi, sometimes when using "one more hack" the console shows

Is there any way i can remove the console? (not the "Show console: off" but deleting the console or maybe even just ignoring it so i can see what i'm recording without the console in front of it)
