No, not really. It is because I have bought an ISCO Ultra Star x2 Anamorphic lens and would like to be able to shoot 1920x2160 to get 3840x2160 24p, for the moment I only manage to get 3200x1290 unsqueezed.

Already anwered. 1290 is max resolution if not accepting cropped recording. Sell your lens and use anamorphic preset instead imo.
And, recommended to test out those presets and really learn them one by one since it will eventually help you realize what works and not atm.

I have well understood what you've said, what I don't know is how to access more vertical resolution in crop mode without using an anamorphic preset.
I can shoot 1920x2332 24p in anamorphic, but I would like to shoot this resolution with 24p but without the deformation. Is it possible? What preset do I need to use?

Thanks,

None of them will actually. Only anamorphic will work with standard frame rates.

Anamorphic mode is not for anamorphic lenses.
What could help is crop mode, if there would be decent 4:3 preset then you could iuse some 2/3'' sensor lenses with your anamorphic lens x2 to get similar FOV to what you have now and maximum resolution .
crop modes are optimized for 16:9 and cinemascope ratios, You can trim sides from 16:9 but its not real maximum 4:3, its just not many people need it
In theory 2200x1790 could be possible if you would take sides from 2.8k and applty them to top and bottom resolution while reducting left and right, Not sure if that would help but it might be the highest 4:3 resolution this camera could handle at the moment and this also could help us get nice 16mm film emulation preset in 4:3.

I think that's a very good answer to help him.

I agree, I just wanted to test out a few things, the latest build has gave me some weird issues that's I've never encountered before, lot of battery pulls, but I'm not sure if it's the build, something in the settings being off, or the camera dying on me lol

thank you for the links :)

You could also desctibe your issues here. What preset used causing those issues and even upload your SETTINGS folder for us to reproduce.

I didn't want to bother you because I know you're a busy guy and I thought you was taking a break from the 5d3 stuff.  If I can recreate it I will try to take a picture of it.  It's been a few different things all in the newer 5k anamorphic mode, like full on pink distorted frozen screen, another issue a error pops up on the screen that looks more like from the canon side of things, and other occasions of a hard freeze within a few frames. fps override is off on all issues, but I will try to recreate them, I was just worried that the canon error may have been super bad. lol

@Danne

Can you Re-center again in the new 3.5K 5x zoom crop Preset? It's a little bit to bottom mid.

Thx

Hi guys,

thank you for your amazing work trough all these years.

I'm using latest Danne's crop_rec_4k & ISO experiments with 5D mark iii.

With 3.5K 1:1 centered x5 preset I get constant "compression error -3" and "stdev too large" errors after about half a minute of shooting resulting in corrupt frames in MLV app. But the recording continues with green status. I'm using SANDISK Extreme Pro CF and SD cards with overclocking. It happens with any of the possible resolutions.

Preset 3.3K works fine but I can't get it to record 25FPS. If I try FPS overide to 25FPS camera crashes.

Any clues for me?

Thank you!


I tried 1.1.3 and 1.2.3 firmwares.

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

- Centered 3.5k preset.
Needs some testing...

OK, 3.5K is now a little little bit too top mid and 3.3K the same, but bottom.

Well, better at least. Don´t think I can get it closer to center.
Who said anything about 3.3k?

Only I, just for testing and comparing. And yes, it's much better at least.
Thx.

Centered both 3.5k and 3.3k a little better I think. Please test.

I'm not sure, but I see no difference in 3.5K. 3.3K is nearly perfect, but I get some crazy vertical lines/ stripes in all previews.

Hm, I´ll have a look. Does it affect recorded file too?
EDIT:I don´t think what you are referring too regarding stripes is related to recent changes. This has been there for long. As long as recordings are fine all is working as before and expected.

Yes. But this issue is only in 3.3K.

Yes, it´s because of modifying width to be able and preview cropped and in realtime. Still good.
