Danne's crop_rec_4k & ISO experiments

[andy kh]

i stil cant shoot in 50fps with your latest build. 60fps is fine. i have been shooting 60fps for the last couple of hours without issue. just tried 50fps this evening and i get some error which is very strange. if i restart the camera canon setting jumps to ntsc from pal. i tried setting to pal again and shoot at 50fps and whenever i get this error i try restarting and jumps to ntsc

- Minor change. Maybe it affects 50fps mode positively. Can´t test, no cam here.

Changing between PAL and NTSC is like you describe sometimes not really changing and goes back on restart. Because of this I want to separate 45/48, 50/60 fps to independent presets. This means they can be run in either ntsc or pal as long as camera is set to mv720p. 45/48 is already like this but havn´t had the time for the other two.

Anyway. When I tested myself before it seemed to work. Are you using 5D3.1.1.3? Maybe reinstall?

If people are testing please take alook at 50/60 fps mode and report back if working or not.

About your screenshot it´s related to compression handling in mlv_lite.c. Something is affecting it so it correctly reports files are getting corruption issues.

And as always. Changing presets also likes pushing canon menu button to settle regs...

stil the same problem. sometimes it works fine. the problems occurs after recording 3/4 times

i get som corrupted pink frames

i dont understand why there is no such problem with your 2nd Apr build!!i have been using it for so many days and i havnt found any problem so far

[Danne]

2nd april from my branch/builds?
What firmware used 1.1.3 or 1.2.3?
Could you share exact settings?

[andy kh]

yeah 2nd Apr if i remember from your branch/build. it works perfect
im on 1.1.3
 my settings are
pal in canon menu
720p@50fps
activate crop mode 1920 50/60 3X3
 edit : i set to 1920X818 spect ratio 2.35:1
14bit lossless
real time

[Danne]

Could you test this version of mlv_lite together with the latest build?

mlv_lite from 2nd april. Want to know if it´s related to something in there or in crop_rec.c.

[andy kh]

no it doesnt work

[Danne]

Doesn´t work at all or work and gives compression errors? I need my camera I believe...

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

Mainly I separated 45/48fps modes into two and they run in either 50 or 60p mode. Upscaled 48fps to 1060p:

New build anamorphic  test in5Diii 123. Thank you

- Separated 50p and 60p into two separate presets same as 45p and 48p. Means they will work both in PAL or NTSC mv720p. Also modified numbers some. Seems more resistent from compression errors in 50p mode now

Thanks to andy kh for reports.

[Quentin]

Awesome!

Is it possible to have these presets (45/48/50/60 FPS) in 1920 1:1 ?

[Danne]

Might be. I could have a look in implementing the x3crop in Crop mode sub menu similar to how it's done for eosm.

[Danne]

Awesome!

mv720p mode and x3zoom seems restricted to reduced height like what you get when in mentioned 1920 1:1 mode. I have a hard time figuring out a1ex pack modes on cmos regs but maybe once those numbers are "decrypted" we can revert to some more obvious numbers and start constructing more freely.

EDIT: Nudged cmos1 and some other regs and seems I´m on to something. Stay tuned. I post when I gt something working.

Key are these two regs combined or resolution looks like sheit:

Code: [Select]

                adtg_new[3] = (struct adtg_new) {6, 0x8000, 5 + reg_8000};
                adtg_new[17] = (struct adtg_new) {2, 0x8806, 0x6088};   

- x3crop now works with higher frame rates 45/48/50/60 fps. Simply be in one of the mentioned presets in mv720p and then select x3crop from within Crop mode sub menu:

- x3crop toggle working for 45/48/50/60 fps modes. Function same as for eosm here:

Hi Danne, just to say thank you for the work you do (and all FM devs of course), I've got a 5dmkIII and last week I needed 720p footage at 48FPS, so I've just overwritten my previous ML 113(experimental, the 4K raw video recording 22-7-18) and the 2 hours shooting (not continuous) went all great!!
I'm going to update in the next days as long as you go on coding...

[Dmytro_ua]

- Refined anamorphic presets so it now gives continuous:
1808x2300(2:35.1) = 5425 x 2300

Wow, this one is awesome! Works without problems.

Hope, sometimes we'll have a realtime liveview to have a possibility to shoot moving objects, not only static frames from tripod.

Thanks for your job!!

[Danne]

Yes, 5D3 can produce some heavy resolutions.
There's real time preview by the way. If in framing mode press halfshutter for cropped real time preview.

Yes, I understand what you mean, but what is a real purpose for such a preview? The proportions aren't correct, we can only see a massively stretched top part of an image.

[Danne]

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.

Danne, for me  continuous recording  in  anamorphic 1600X2332< 16:9!   another way round to  preview  framing before recording  is   press hold the AF Lock button (the  lens  should  be  in AF  Mode)Cheers...

[Danne]

Yes. That should work just fine but not really 16:9 when upsampled in post .
