Where is that document about how to report bugs someone?
I really need some deeper info around any bug reported. For instance. Most often it has to be reproduced or how else can we try and fix?
If you tested around and safely know how to reproduce the bug then tell me canon settings, especially around focus. Then maybe do a short screenrecording publish your exact settings used, preset and so on...

Changing resolutions how? If you get a reproducable freeze we have something look at here, otherwise it´s just normal buggy eosm behaviour ;)

nothing to do, this latest version, July 9th, in my eos m is completely crazy

09 aug build is the latest build

Yes, sorry that's correct...hmm, just haven't experienced this issue with the build. Focus aid (Default Mode) works perfectly when the shutter is half-pressed or even if you hold the left wheel button.
Just ensure all the correct modules are enabled, otherwise uninstall ML, format the card in the camera and install it again..

Yeah, sorry. I’m unable to provide any files right now.

One other thing: I can’t get a shutter above 1/160, ML won’t let me. Anyone else experiencing this..? Is there perhaps a simple button I can turn off..?

What is "above" to you? Faster or slower? Does it happen in movie (which Canon movie mode selected?) or/and still mode?
Have you already tested to reset ML to defaults and retried?

Please! Keep in mind offering a way to reproduce your error step by step! With info as given above it is just guesswork.

Again: Have you already tested to reset ML to defaults and retried?
Again: In which Canon mode are you? 720p50/60, 1080p24/25/30?

Does it happen starting without ML, too?

Hello, does anyone know how to get horizontal lines that don't oscillate from top to bottom as interferences, after stretching the image?
Thank you.

Hello, please could you tell me how to decrease the horizontal oscillation of lines after stretching 4k 1x3

Why don't you show a picture or MLV with your problem? Never saw oscillating lines in a clip...

Are small yellowish undulations in horizontal oscillating, can it be because of the frames?

hi! made some test videos yesterday and made footage to test black sun issue, found that it not gone, there is some gray colors, that turn to pink if you try to move highlights even few steps down.
there's video about issue to show you what i mean

Well, could you upload a sample file? Also, is this happening in for instance ACR? Did you compare other NLE;s?

sorry, can't understand meaning of ACR and NLE with my english)))
uploaded 3 mlv files, all of them have same issue, so i think in every footage with direct sun it can appear.

Ok, did some fast testing. Set white level to 14000 on Mlv App. It´s now 16200. This issue also appears in acr(adobe raw engine).
So these shots are done under iso 100. Is this problem also happening in iso 200 or iso 400? Might be the same issue as described here:
http://www.magiclantern.fm/forum/index.php?topic=16040.msg191131#msg191131

By the way. is 16200 a good default value for eosm? I probably should know this but if anyone can find a more correct white level default please tell...

16200 for almost all cases is absolutely fine! The EOS M has only a RAW Dynamic Range of 11.2 EV, so pushing it around a lot won't help. My 6D has 12.1 EV and doesn't suffer much from these issues as the DR allows for better highlight/shadow recovery.
An ND Filter & good exposure is the key here to somewhat avoid these pink highlights and a bit of tweaking with the highlights and white levels in MLV App to which I have found 14444 or 15000 to be my go-to, although not always the best options.
Attempting to recover blown-out highlights is going to cause some issues, especially with a camera that has decent dynamic range, although good enough for most cases.

For 100D safety margin is 13400 and for the rest isos 15200. I will eventually put in 15200. Would like to differ iso 100 to 13400 but my iso_climb function and other anomalies will make it better for an overall 15400 white level in 14 bit:
Code: [Select]
#if defined(CONFIG_100D) || defined(CONFIG_700D) || defined(CONFIG_EOSM) /* other models? */
    /* http://www.magiclantern.fm/forum/index.php?topic=16040.msg191131#msg191131 */
    /* 100 units below measured value = about 0.01 EV */
    /* due to iso_climb routines this value has to be set to a compromise */
     default_white = 15200;
   // default_white = (lens_info.raw_iso == ISO_100) ? 13400 : 15200;
#endif

Thanks Danne. Yeah, a default White Level of 15200/15400 would help. The ISO climb function is genius.

From my experiments most stable were 12 bits with white leve because it wasnt jumping to different values from clip to clipl, its 5138 for me,  i have to dial it manually in MLVApp , in 10 bits white level jumped to different value between clips from the same shoot , it was not one number most of the time, with 14bits i did not test this extensively so i settled for 12.
Tested this with highligt reconstruct and adjusted white level until i had it reconstructed without pink or magenta shift of pure white.

made tests for different iso, 100-800, on direct sun.
in every shoot black sun problem appears with white level 16200.
white level 13500 solve everything in every shoot.
for another shoots without sun white level 16200 is good.

Good day to all.
I am very glad that I have such a good camera,   such a tiny size with 22mm!
I have one question - I can not achieve long, stable video recording (especially with a bright day or room) in the 1080p\rewire\14bit to the Samsung EVO 2 128g card. Are there any  settings that affect the stability of recording to the card without sacrificing quality?
