General Help Q&A / Re: Canon 5D Mark 3 Questions
April 13, 2024, 01:31:16 AM
1) no
2) yes
3) it works but it's not a correct framing even if you stretch it to 2.35:1
4) you can use mlvfs and import it straight to resolve, no conversion, not sure about premiere but resolve is superior anyway, plus you have way more data to work with (raw video) instead of converted to mp4
5) already answered
General Development / Re: Ultrafast framed preview (5D3)

Amazing! Appreciate the effort
Seems to be working great so far, haven't experienced any bugs yet, appreciate your work Danne!
Works great! I've had the same idea but no skill to implement it. Only one problem, the display goes to sleep if you don't tap it once in a while, probably a keep-awake app will help. Otherwise it's perfect, really helps with focus confirmation on 1x3 anamorphic mode on 5D3
Yeah I'm having the same issue, I can get normal preview on a phone-usb-camera with mlv1080 mode but not 5.5k anamorphic. Both modes in canon menu give a distorted view. It's usable for focusing, but proper preview would be amazing.
Amazing work Danne, the anamorphic 5.5k preset is great!
Just a one small request, is it possible to format the card yet keep the Magic Lantern as in the nightly builds?
Absolutely amazing work reddeercity! Glad to see this old but great camera being pushed to it's limits.

I've just got 5Dmk2 a few weeks ago and I've been experimenting with these raw builds, most of it seems to work fine but for the heck of me I can't figure out how to enable 48p mode. It would be really useful cause I've just got a glidecam and that would be a perfect combo. I tried following the video guides, guess I'll try again, I know it should work. Looking forward for future releases!
Aright, I did some tests

Both shots are 1280x544 2.35:1

24FPS @1080 Canon Menu. 172 Frames before skipping.

24FPS [used Hi Jello Exact FPS to get 180 shutter] @720 Canon Menu. 2364 Frames (!!!) before skipping. Just have to stretch it vertically to get the normal dimensions

720 image looks a little bit squeezed even though it's been stretched to the same dimensions. Stretched it 141% vertically. Im blown away by the increase of frames captured and thanks for the tip for achieving 180 shutter.

EDIT: I stretched it by 167% vertically to get the same exact crop as 1080.

In other words, it doesn't make any difference if I use a 45mb/s or a 95mb/s sd card? I will still have the same max resolution on the 550D?

EDIT: Does it matter if I have 1080p@24 or 720@50/60 with FPS override? Will the 720 make me get better resolution.
'Cause I can get the right shutter speed with 1080p@24. When I use 720p@50/60 I cant get the 180 degree shutter speed. Any ideas?

Yeah, it doesn't matter, because 550D internal write speed maxes out at about 21MB/s
When I set 720 in Canon menu and FPS override to 24 I can't set shutter more then 1/40 either. Don't know why.
But that way the image is a little bit squeezed but you can stretch it in AE. I get more frames recorded in 720, the only problem is the slow shutter. No idea how to fix it.

VERY interesting ! Many thanks ! Can you tell what software and parameters inside it you used to stretch the last image ? Many thanks !
Also: what means 0.1x - 1.3x and 3.0x ? Zoom factors of the lens or the "quality factor booster" of h264 magic lantern ? Or what else ?

Thanks! I used Instant HD to stretch the last image. But it doesn't make a huge difference, just stretching a composition in AE does the trick.
You're right, 0.1x etc. is the bitrate of h264 in ML. I noticed that if I don't go over ISO 800 I can film on 3.0x without stopping. And it does make a difference.
I'll make some more tests and add it to this post in a while.
I did some comparison shots

H264 0.1x  1920x1080 16:9
H264 1.3x  1920x1080 16:9
H264 3.0x  1920x1080 16:9 cropped to 2.35:1

RAW 2.35:1 / 1152x490
RAW 2.35:1 / 1152x490 stretched to 2539x1080

There's no doubt which one looks the best :) RAW is so much sharper and natural looking, also having the ability to edit it in Camera RAW is just unbelievable and it upscales nicely.
