crop_rec and derived builds / Re: Danne's crop_rec_4k & ISO experiments
« on: February 05, 2021, 02:06:57 PM »
Hello, could you explain what the parameters are, for the x5 mode centered 1: 1 from 3.5k to 3456x1728 10bit, I can't use it. Thank you.

I'm using a slightly tweaked build of Danne's work with just a few extra Ratio presets in the Movie menu, but the settings below should get you there with his build.

Presets  3.5k  1:1 centered x5
RAW Video
     Resolution  3456x1728
     Aspect ratio 2:1
     Data format 14-bit lossless
     Preview Framing
     Crop rec preview auto mode
     Card spanning on
Bit Depth 10 bit
Ratio Off
SD overclock 160mhz

and most importantly, you have to have the right SD card. After seeing success with other folks I got one of these and no problems. It's got to be the 170mb/s. I have one of the 95mb/s ones and no luck with it. Haven't seen the lost sound issue.

Any fast writing compact flash seems fine. I use a variety of Komputer Bay 1000x or better cards.

Lately I've been shooting in the 3.5k 1:1 centered x5 mode at 3456x1728 10bit. It's continuous with card spanning and SD overclock, but only a few seconds without either. There are certainly plenty of good modes without spanning or overclock, but it does open more options.

I don't think anything outside of the 1080p stuff is expected to give a real time view.

I had zero luck from a couple of the 95mb/s cards that I had laying around. It wouldn't write anything if OC was set.

A new SanDisk Extreme Pro 170mb/s worked fine.

Left good, right bad.

Amazing ! how can we download it as a autoexec "classic ML file" ? (I know nothing about coding, I'm more into video..)

Only been tested lightly with 1.23. It's just the croprec module. Drop it into the ML\modules folder of your card. It should play nicely with the rest of Danne's latest build.

Edit: Just saw Danne's post and I'll try to update this later today with full builds.

Modules Development / Re: Tilt Calculator module (tiltcalc.mo)
« on: July 19, 2020, 01:24:11 PM »
Until the where we land for source control question is settled, the code is squirreled away at https://github.com/ewinemiller/TiltCalculatorForMagicLantern

Since the "where we're landing" question doesn't seem to be answered yet (or at least I couldn't pick it out of the end mercurial thread), I just forked your git and stuffed the changes here https://bitbucket.org/ewinemiller/magic-lantern_dannephoto_git/src/newpresets/.

Hi all,

If anyone is interested I put together some intermediate presets for 2.20:1, 2:1, and 1.85.1. I was looking for something a little in the middle of the 16:9's crop and the 2.35 aspect ratio. All are continuous on a 1000x KombuterBay without spanning or anything.

I will try to put it up on bitbucket, but have to get my head back around that process again. I don't use it enough to be comfortable or even remember the basics, and might not have time to work through it this weekend.

All changes in crop_rec.c from Danne's crop_rec_4k_mlv_snd_isogain_1x3_presets branch. Thank's Danne for your work. It was super easy to build on.

Regards,
Eric

Switched to Unbuntu 18.04LTS and it works fine.

I did pick Ubuntu 20.04LTS for my Linux version

Hey folks,

I'm giving this a whirl and running into python problems when it tries to compile the modules. The error I get is

/bin/sh: 1: python: not found

I found a reference in one thread where adding

PYTHON=python2.7

to the Makefile.user helped with this problem. For me not so much. Also tried python2. I know it's using the value because if I change it to python3, it yells at me about a syntax error in the script.

  File "../readme2modulestrings.py", line 40
    print "static char __module_string_%s_name [] MODULE_STRINGS_SECTION = %s;" % (a, c_repr(name))
          ^
SyntaxError: invalid syntax

If I type python2 or python2.7 in bash, I do get the 2.7 python shell so it does seem to be installed correctly.

Any suggestions? I did pick Ubuntu 20.04LTS for my Linux version and I'm trying to compile Danne's branch (though I had the same problem with unified).

Thanks.

Canon EOS 5D Mark II doesn't have an SD-card interface ...


It really has been a long time since I had a Mark II. My bad.

@ewinemiller did you really read what @teopimenta said ?

To be more helpful ! read the whole post .


Yeah, I did and have made the same goof. With the non-experimental ML, it will write the RAW to the card you have selected for writing. A 1066x CF should write fine, a SD card will give the exactly the results described and benchmark the low numbers.

@teopimenta, been a while since I had a Mark II, but when you press the Q button, there is a spot near the lower right that selects which card to write to. Make sure the compact flash is selected, not the SD Card. I believe its the top one. Another thing to try is benchmark the card on a computer over a USB3 compact flash card reader. If it runs that slow everywhere you might have a counterfeit.

Sounds like you're recording to the sdcard. It's limited by the controller.

what I not undestand, is ..what you can NEED MLV_REC.mod ?

I believe I have seen some conversations that now that mlv_lite has sound, mlv_rec is no longer necessary. But that only happened a couple weeks ago, so give it time.

15
Then how come it does not boot anymore, the F.A.Q. says that it can cause that even, i would say that is damage.

What you're describing sounds like a hardware failure. You keep talking about AA batteries. Are you using a grip? Have you tried removing the grip and using a real Canon rechargable battery instead? I have read about shorts in some of the cheap grips that burn through batteries.

16
So you didn't get the same problem in v.12.5. Is it possible to import these footages to v 12.5 save and then continue the work on v 14 and take advantage of its new features?  :D

I don't think so. One of the things I was trying to open was a project I believe I originally put together under 12.5. I think mine was crashing whenever it handed the DNG off to the GPU for processing which it still needed to do. If yours is a similar problem and non-DNG footage works you might be able to render out to prores or something in 12.5 and then grade/edit in 14.

17
I fixed my problem by explicitly setting the GPU processing mode to CUDA instead of Auto.

18
I am using Davinci 14 and have the same issue while attempting to import a cDNG folder: while draging it to the media pool the program crashes. I can't even click on the folder that contains the cDNGs prior to draging them into the media pool. I used MLVproducer to convert MLV to cDNG.

I think it's something in Resolve 14. I'm seeing the exact same problem under OSX. Resolve crashes trying to open ML DNGs (maybe all, just don't have anything else to try). This is old footage that worked in earlier versions too. All of it was generated with mlvdump.

« on: September 20, 2017, 06:51:41 PM »
But it isn't possible in an official nightly build?

And will 1920x1040 at 48fps allow me to record continuously?
Correct, not available in nightly.

It will depend on your scene and ISO, which feed into how well each frame compresses, and card speed, but in general yes. If you find that that you're on the edge, you can reduce the vertical height to reduce the bandwidth requirements.

The experimental build at

https://builds.magiclantern.fm/experiments.html

will get you 48fps at 1920x1040. Seems to work fine in my brief tests.

21
Hi Magic Lantern users,
I haven't been updating my ml build for 2 years now..
is there already a way to see the proper and right frame when recording in crop mode?
It sucks that we see the 5x magnification, but actualy its recording in 3x magnification.
Any workaround?

Thanks so much

Check out the experimental builds. There's a very nice crop mode activated with the zoom button that gives the correct framing.

« on: August 22, 2017, 12:07:07 PM »
Are the experiment downloads stand alone ML or are they to be used alongside a nightly build?  I'm unsure what I'm supposed to do.  Do I remove the latest nightly build then put the experiment on my sd card?  Or do i copy the experiment files alongside the nightly build files and put both on the sd card?  Please Help. 

Stand alone, use them instead of nightly.

23
I think last time I tried the build 3.5k was almost continuous but without realtime live view or sound recording. Is this still the case?

Mostly. I can do 3.5k 2.67:1 continuous with a fast card in the zoom mode crop. Live view preview is responsive enough for framing that mode, but I think the other hires non-zoom modes still have problems with live view. No sound. Very usable though.

24
There is no sound in crop_rec experimental builds. mlv lite does not support it. Use an external recorder. The Zooms are nice.

Hi everyone.

I have problems with sound record on 1.2.3 firmware version, experimental build.
Got 4 modules on - crop rec, dual iso, mlv lite, mlv play

What am i doing wrong and how to solve it?

Kind regards, Anna

25
Pretty sure I still have it at home. If it doesn't show up from another source I can post evening east coast US time.
