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

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

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.

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

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.

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 ;)

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?
