I am not certain if it is possible, to drop resolution for a higher FPS.
For instance 1280x720 @ 96FPS

Dmytro_ua · « **Reply #101 on:** July 16, 2019, 03:37:57 PM »

Is it possible to enable proxy recording from 1920 3x3 preset?

Danne · « **Reply #102 on:** July 16, 2019, 04:26:49 PM »

What exact preset are you referring to?
When using proxy recording function also make sure you are selecting 2nd card(SD) in canon menu. This way proxy goes to sd and raw to CF.

Dmytro_ua · « **Reply #103 on:** July 16, 2019, 07:37:00 PM »

I've tried your latest build with 2:35.1 10bit lossless 25fps (i've got 1720x2200 px).
When I enable proxy - it's stretched and cropped. I understand, that it's somehow made from 1x3 proportions, that's why it's not usable. So, I assume, aren't these two processes independent (MLV and proxy)? Can't we somehow use nice proxies from Alex's build 1920 (3x3) with your 1x3 raw 1720x2200 px?

Na, that would mean a corrected liveview output parallell to shooting raw. The holy graal if you so like

Hi, Danne!

I'm sorry, maybe it was mentioned before, but I cannot find an information about what your lua script exactly do? I mean step-by-step

Danne · « **Reply #106 on:** July 26, 2019, 11:44:57 AM »

Why not test it? It sets optimised settings for anamorpic 2.39:1 recordings.

I did try. But I shoot mostly with 2.35:1, so I want to be sure, if I change 2.39 to 2.35, I won't mess anything else.

Danne · « **Reply #108 on:** July 26, 2019, 12:54:24 PM »

No. That's fine. Once you run the script you are free to change anything after.

So, what the script is actually doing? Can I do the same manually from ML menu?
I'm just curious, it would be nice to read some description of it. But if you're busy, don't bother

Danne · « **Reply #110 on:** July 26, 2019, 06:34:49 PM »

Yes, manually. It's only a helper script to get going. Originally created eosm on mind.

Anyone knows how to record continuous at 14-bit lossless at 1440p 24fps? I get pinky/black preview on my LCD screen.

These are my selected settings:
Global draw: liveview
fps override: 24 fps
crop mode: 4K 1:1 and x3crop set

RAW video:
2656x1494
16:9
14-bit lossless
preview: realtime
croprec preview: auto mode
kill global draw on
sound on at 48khz

Any tips on what I am doing wrong?

With a slight modification of the aspect ratio (1:2 in raw menu and 2.35 in crop rec menu) and resolution to 1808x2300 in 14-bit lossless of the cinema lua script I managed to get automatically the following in MLVapp:

5424x2300

Just to make sure I have understood this script correctly. Does this signify that the streching by 3-fold 1808x2300 to 5424x2300 does not result in any loss of pixels? Meaning that pixels had been squeezed and then streched back making this true genuine 4k footage?

ibrahim · « **Reply #114 on:** September 26, 2019, 12:31:03 PM »

I've used the cinema lua script using an external monitor. The issue I am having is to see the lower end of my footage. I know that there is a stretching going on vertically, which is why I cannot see the lower end of the filmed footage. Is there a way to say shrink the entire frame so that the lower end can be seen? Any other solution?

Dmytro_ua · « **Reply #115 on:** October 15, 2019, 06:26:03 PM »

1. iso climb: in menu it is mentioned INFO(5D3), but it does nothing
2. x3crop toggle (halfshutter press (5d3)) in Press down or Set mode: x10crop not compatible with x3toggle - but i'm not in x10crop

There is a misprint for iso climb: in menu it is mentioned INFO(5D3), but it does nothing

Is this related to the 2019July20 or 2019Oct13 build from @Danne's bitbucket download page?

New builds 5D3:
https://www.magiclantern.fm/forum/index.php?topic=23041.msg216899#msg216899

- Removed a few features due to lack of time bughunting
Removed: x3 crop toggle, iso climb.
All good stuff still in there so shouldn´t make any difference.

GullRaDriel · « **Reply #119 on:** October 16, 2019, 09:54:28 AM »

Thanks a lot for all the good job you're doing.

I'm testing a lot of your builds, and this one will be tested tonight. I'll be putting a review.

Danne, if you need me to test something special feel free to ask. As I'm a developer too I'll try to clone and build your version myself.

Danne · « **Reply #120 on:** October 16, 2019, 10:14:45 AM »

Ok, sounds good. General tests of the presets please go ahead. Not all sub menu items will work here and I am not up to date with this branch atm since I put all focus lately into the eos m. If you and others can find bugs and start working on fixes just go ahead. I will help out with pointers etc.

GullRaDriel · « **Reply #121 on:** October 17, 2019, 04:13:44 PM »

I've just tried to compile on debian testing, the classic unified branch for 5DM123.

I had to comment out the include module_strings, because the file is not present and it gives a compilation error.

Make zip made me a zip, I do not yet have a working qemu to test it, it'll come soon !

GullRaDriel · « **Reply #122 on:** October 18, 2019, 02:56:26 PM »

Edit:
Everything is working so far, with your branch build on my debian.

I don't get how I can correctly fork your branch and see it on bitbucket. We'll see what to do on that.

Part of the workaround technique. Framing is done from real buffer very slow and focusing can be done while holding halfshutter while recording. Then back into framing again. In and out. I can work with that and capture pretty much anything I want.

I tried 2019Oct15.5D3113 and 2019Oct15.5D3113. This feature is very very useful but sometimes(mostly) does not work for me. When it works and after pressing half shutter, it backs streched view again.

When I run your Lua script, everythings are fine and recording is ok. Low fps and laggy preview but at least not streched, framing is good. (I can get 5424x2270 24fps 10bit/12bit continuous)

When pressing half shutter for focusing:

And it stucks there. I can't see correct framed version again. Sometimes works 1-2 times, then streched view again. Also freezing camera when change aspect ratio on crop_rec menu.

Am I doing something wrong?
Thanks.
