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?

Hello, please could you guide me how to decrease the 4 or 5 lines of small red horizontal dots that come out permanently after recording 4k anamorphic 1280x1866 1x3 12 bits in clipping, 2.39 format.
Thank you very much.

i used to use the samsung evo plus 128gb the faster model there is 2 versions apparently. and at times i got upto 45MBps it was not stable at all somethings did help such as using the card warmup, using prerecord and using a differnet sd apapter as mine was a micro sd. anyways best advice just get the sandisk extreme pro. the annoying thing for me was that i bought the evo plus specifically for ML as my research showed it was "good enough" but i guess i was wrong.

I am using MB-MC128GA. The card is fast enough, recording in the card reader is about 83 megabytes per second, but for some reason the recording is interrupted periodically in bright light. This is especially aggravated when the memory card is full more than 70 percent.

File system used: exFAT or FAT32?

Can someone tell me how to activate a 3k setting in mv_lite without using crop_rec. I have noticed a conflict between the two when shooting in reduced bit rates.

Would I have to do it with a Lua script as that is how I activate 2.5k now.

Hmm

Hello everyone, I have the same problem as Fadis, same samsung 128gb, exfat. On my PC it gives very good read/write speeds but on EOSM it's very unstable and typically gives about 25mb/s.
BUT, if I reformat this card in camera then I get stable max possible speed for EOSM. What's the reason for this to happen? Why formatting helps, but after some short time card starts underperforming? Even tho on PC speeds are stable all time.

It would be nice if more scripts were included in that menu with various working settings at different resolutions, crop modes, or aspect ratios. It would definitely make the camera easier to use, especially with my peanut brain.

@Hmm Guess that's why we all use the Sandisk Extreme Pro SD card just because of the issues you're having right now

Why You Shouldn’t Use MicroSD Cards In DSLR Or Mirrorless Cameras
https://www.howtogeek.com/398225/why-you-shouldnt-use-microsd-cards-in-dslr-or-mirrorless-cameras/

"This is an interesting subject, and I started digging into the SD protocol a little bit to figure out why his is happening.

One thing I've discovered is that the SD interface is a serial interface, but with a twist. Devices can use one or four wires for data. The choice of single-wire SPI vs 4-wire transfer obviously is going to make a huge difference in transfer speed. It's possible that the SD adapter you were using didn't have all of the wires connected, or there was a defect in the card, leaving a wire disconnected and causing the camera to fall back to 1-wire SPI.

A little reading on this article has also illustrated that a high number of I/O operations per second and fast sustained throughput are not the same thing, and cards can be optimized for one or the other.

Finally, I looked up the SD protocol, just to see if there's a limitation in µSD cards that I'm not aware of. Electrically, the only difference seems to be that SD cards have two ground pins, while µSD only has one.

Finally, just for fun, I opened up one of my µSD adapters to see what's inside. It's entirely a passive adapter, with no circuits or electronics - just flat, metal traces connecting the pads on the SD plug to the pins on the µSD socket.

It's possible the bridge connecting the two VSS pins (notice it up at the top) might be causing issues with the CLK or VCC line, but since VCC is the power supply and CLK is the clock, a short on either one of those would cause the card to fail a lot more spectacularly, so I don't think that's the issue."

New build:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

branch:
https://bitbucket.org/Dannephoto/magic-lantern_jip-hop/branch/crop_rec_4k_mlv_snd_raw_only

Been working hard with Jip-Hop to refine presets and all around movie handling approaching the eosm more like a movie cam. Some of the things done recently:

- reworked Movie tab menu(Jip-Hop)
- fast preset access by simply tapping display
- corruption free 4k anamorphic modes(slightly reduced height in raw.c)
- shutter coherency. Same shutter across all presets(fixed a bug introduced by myself)
- Movie Restart for raw recordings(Jip-Hop)
- autoenabling modules(refined by Jip-Hop)
- gain buttons up for higher iso. push down for lower iso, also working while recording
- aperture + ISO(up/down buttons will open or close aperture when max/min iso is reached)(Jip-Hop)
- h264 mov preset, working with x3 digital gain(SET button) and gain buttons(up/down)
- toggling between photo and movie mode working better

Upon install buttons will be reassigned as follows:
SET x3 crop and back to x1.6 mode
Up/Down gain increasing/decreasing(iso)
Tap display startoff preset list
Halfshutter press x10 zoom aid(release for normal view)

For newcomers and for people who just wants to get down to recording do following:
1 - Install above build onto your eosm and start film. Camera will be set to mv1080p 2.39:1 24 fps
Or...
2 - Set your camera into manual focus mode and tap your display to get into the fast access preset list:

Select a preset after tapping your display. Done!:


Reworked Movie tab menu(thanks Jip-Hop):


Movie Restart feature(thanks Jip-Hop)


customize buttons:


h264 mov. Select it from tap display options:


Missing 3K, 4K? Still there. Reach them by tapping "presets" from Movie tab section:


cine 2.39:1 script still there(refined by Jip-Hop)


Enjoy hard open source work!

As always greatful for a1ex sharing his architectural magic lantern code work. Of course g3gg0 and others not mentioned too...

Thanks Danne and Jip-Hop!

That Gain/Aperture adjustment is sweet!

Edit: just tried the Gain/Aperture adustment, when I press down I come into the Canon iso menu. What am I doing wrong?
Also when enabling AF, autofocus doesn't work that great anymore in mcmrewire mode.

New upload:
https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

- Fixed a bug around auto iso. It should also handle x10 zoom aid better now.

EDIT: Yet another small bugfix...

Can you check if you have set the down button to ISO setting in Canon menu? I think that setting is in the yellow menu somewhere.

Sorry, if I'm too blind or too stupid to find it, but is there any way to use half-shutter to start/stop recording in Aug30, as in the previous builds?
I found "Rec trigger" in the raw video settings, but that seems to be only for start/pause within a clip.
I did turn off focus aid within the customized buttons, so I think it doesn't interfer with that.
The reason why I need that function is quite simple; my REC button doesn't work.

Cool @Luther. And thanks others posting about testing and so on. All reports ar of value. Good and bads.

Uploaded a new build containing preset shortcuts. Goes like this:
Hold halfshutter(usually this gets you into x10 zoom) Now also tap display and it selects either to 4k anamorphic or 2.5k mode depending on what is set already. Release halfshutter button and it changes preset.
Next shortcut:
Hold halfshutter and also push SET(short push) Gets you into mcm rewired mode or higher fps mode depending on what is set already. Release halfshutter button and it changes preset.

Also centred 4k modes...
