Try Mlv App. If you find any dots in recent builds please report about it. Dfort fixed map files for all presets.

just tested the new build from Danne (18March)
with my settings (folder) from the March14's build

using the 5k preset as described above

did longer recordings this time (around 2&1/2 mins.) and and did reduced the res to match the 2.5k 16:9 preset. (2520x1418)
I choosed 880x1468 and could record continuous without any corrupted frames.

But, I've noticed that randomly the motion in the image hangs, freezes for short period.
didn't have this in the 2.5k preset. I've tested this with both builds and it does this in both builds, regardless of bit depth (10 or 12)

all at 23,976 or 24 fps, fresh formatted card before testing, each build on an identical card.

These are my approximate tests. I also have to reformat the card to have more stability. Regarding the experience it seems to be random: I don't understand why sometimes I normally see, with the delay given by the signal processed, others in anamorphic magnified x5, sometimes the screen becomes completely dark (less than the set ISO value) sometimes normal. This is the camera monitor, the HDMI output is unpredictable. Very often I can't see anything (lilliput 7 ", neither in 480p or 1080i)

Download dforts maps and copy them to same folder as MLVApp executable. MLVApp uses them then.

@masc:
Could the map files be included in Mlv App as default? Good stuff.

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

- Modifying black level for isos higher than iso 100 by checking raw_iso from lens.h. Only affects preview when recording reduced bitdepths.

in lens.h:
#define ISO_100 72 but seems eosm runs iso_100 as 0x48. Need to check this later. Might help fixing hdr stuff in main builds.

some more tests with Danne's March20 build

I followed the instructions from Danne -> https://www.magiclantern.fm/forum/index.php?topic=9741.msg208959#msg208959

so basically I started the cam with the new build on it, enabled the essential modules, formatted the card from canon menu, after restart I executed the "eosm cinema 2.35:1" script.

then in croprec submenu I've removed the 25fps and in raw video menu dialed down the res to 1136x1920 (which is fairly close to 16:9 ratio)
now, this is interesting - I've forgot to mess with the ratio setting in croprec submenu, so there was still ratio of 2.35:1 set. result was nice, only one corrupt frame out of 3100 and no stuttering or so.
then I've noticed I've forgot to change the ratio, so I changed it in croprec to 16:9 and recorded another two minutes. I noticed also after the ratio change, that res was corrected to 1136x2000, which is little less 16:9 then my set res before. viewing in mlv app, in this clip I've had 7 corrupt frames and stuttering in the movements, not that much, but it was there.

then I changed the preset to 2.5k and recorded at max res of 2192x1234 another 2 mins. no corrupted frames or anything else, clean picture at 24 fps.

so maybe its best not to touch the ratio setting after executing the script.

one is still a bit of disadvantage that even if I can push the crop a bit to the left with reg_skip_left
trying to move the crop up with the other reg results in bad image, so its now impossible to properly center the crop, which at this high res is not quite suitable for c-glass   

will test further, thanks to Danne and others for this.

Today's version installed. Very stable in 4.5k resolution with the cine 2.35 script. More than a thousand frames without errors but when I connect the hdmi monitor it becomes unusable: 1 corrected frame 1 corrupt. Any ideas? Thanks for all!

just curious - how come, 4.5k anamorphic AND old cam / old hdmi should work ? isn't it to much to expect?

I read that it could be used and in fact it works, it looks very good, you can't use the touch but at least you can fire and follow the action without problems ... but it produces so many errors in the recorded frames

I can't help You with that one. But using logic,
I would suggest - maybe You could have a special version with err viewfinder but clean recording, or clean preview with corrupt recording, which if I understood You,
is the case now). for You.
maybe even possible to have both, but for what price?
and a question - does this setup of Yours work with other versions then Danne's ?

Practically no experience with hdmi out connected but seems the setup steals some good overhead causing frame corruption.
Regarding different ratios and stability around them. I put in some heavy testing around 2.35:1 ratio to get that working. Very likely room for improvements and my pragmatic approach fine tuning reg 6008, 7150 and 713c might hold a more stable math that I don't see but I can't calculate it. Yet.
For stable ratios 16:9 or other ratios I could look into suggestions, at least start off for further tweaking...

I have not used other versions than Danne's. I'll try. However the Danne version seems to me to be of the highest quality result. I only try to find a minimum workflow to record a comfortable and safe way

thanks marcello.& wish You luck, trying the nightly , experimental and dforts, even the old TL versions with, to check out Your pref. setup. sometimes also imagined the need to have another than the build IN screen for convenience or sheer necessity. f.E. indoors, having the cam on tripod 6 feet high, the wall behind, then you think, its impossible to check the picture without a ladder .
me too & all of us like Danne's and other Dev's effort and Knowledge to circumvent the crazy-ness of the cartel of the industries.
so more resolution what everybody wants and willingly pays for - we get for just a smile.

this is great and the question is, - how come, I don't help at all with this stuff, but I wish, that to become true, what I need right now, because this would be awesome. isn' it strange , how difficult (see  diffi - cult) it is, to help with something, one self wish to the heart? so what can we do about it, as non dev's.
I hope You check out Your setup with the other versions of ML which are at Your fingertips and if You don't mind report here Your findings.

@Danne - thanks for clarification in general, much appreciated.
@masc - thanks for the new MLV App !

Pretty exciting new stuff on the EOS-M, congratulations Danne!  Any chance that the 100D receives an update too?  I would love to test, especially now that MLVApp v.1.6 handles this new HDR stuff so well.

Not my 100D here but I think it handles hdr well already. Just set mv1080p_mv720p mode to 50fps and enable hdr from the usual place to enable iso switching. Maybe the mv720p 3x3 crop rec setting would be even better here.

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

Some bleeding edge stuff. Tested around some on my eosm. Also added for 100D(untested).
commit:
https://bitbucket.org/Dannephoto/magic-lantern/commits/cdbae199254873317ea7b665ee6f4d443bc7edc7

Please report how it works.

- Moved sd_uhs code into RAW video(mlv_lite) and erased sd_uhs.mo and the related lua script
- Refined eosm cinema 2:35.1 lua script(will enable sd_uhs in RAW video menu)

Just test the last build MCM mode 24fps 16:9  48fps - 12 and 10 bit 16:9 works perfect first time i get some corrupted frames , but then format card and try again and there was perfect footage. Also good idea to put sd hack into raw menu. Thanks again Danne

Also good idea to put sd hack into raw menu.

Why? I'd use this option for still photos, too.

In my opinion, sd_uhs and MLV recording are very different things and should not stay in the same file.

@Danne: sorry to say, but you really need to make your commits atomic and readable. Otherwise, you'll end up with code nobody else can follow. OK, I can probably reverse engineer it, but that's not the point.

I'll have a look @alex. Thanks for links.
And yeah, good for stills and maybe even h264 recording(pushing fps override etc)
