Danne, this is unreal!  :o
I have been playing with it yesterday and today for a couple of hours... testing high res, high fps and dual iso modes.
This is like dream coming true slowly, Its really blowing my mind what you guys can do with these tiny cameras.
Especially I am blown away by 50fps mode. I set fps to 48fps and horizontal res to 1600px (2.35:1) and it is working superbly. Now and then it skips or freezes on one frame but other than that, it is awesome. I think my card is not fast enough to sustain higher res, cos I am getting somewhere arounf 35MB/s writing speeds with SD hack on. (SanDisk Extreme UHS-3 32GB)

In other modes (1x3 binning - the last one) I am getting a few pink frames.

Anyway.. I am super stoked about this!
Thank you and keep up the awesome work Danne.

Great to hear that it´s working. Almost without quirks. All reports on corrupted images are welcome. I am still tweaking and testing.
Yes, a faster card should work with around 54-55mb with the hack enabled. I am using a sandisk 95mb extreme pro I think it´s called. Not sure what other cards are working or not. A1ex has all the insights...

By the way Jonit. What 50fps setting are you using? There are two:
CROP_PRESET_3x3_mv1080_50fps_EOSM
CROP_PRESET_3x1_mv720_50fps_EOSM

hi
just downloaded Danne's last jan19 build and did some little testing with the 1x3 mode
from 5 clips only one has had two corrupted frames just from start - the first white, the second 'normal corruption'
waiting for tomorrow to do more tests.





Image seems to look identical to what I saw on the camera display
settings - 2,35:1, realtime LV, sound, 10bit.

Also have the same sandisc card but with sd_usd hack the speed not getting higher than 35mb\s ... with old builds it was around 45 mb/s

You can test your card through bench  module(not included in this version but get it from one nightly build).
If you run most presets continuous when set to 10bit, 2.35:1, sd_uhs hack on it should be ok. Works here.

hi
some results testing Danne's last jan19 build.
camera settings from canon menu - videosystem NTSC, 1920x1080@24
camera settings from ML menu - Overlay>GD on all modes, Focus peak ON, Movie>RAW video>Preview Real-time (Halfshutter press to frame, works great!) , Sound ON


 1.,    the mv1080p 1736x1158 mode (which is 3:2 ratio, same as the sensor, could this be fixed in the croprec/ratio menu? ) records 1736x976 (16:9), (does not change even if I set Aspect ratio to 3:2 in RAW video) @ 24fps without problems. very nice. did a 15 min. recording, cam temperature stays at 48°C, no frames corrupted. green record indicator all the time.
 2.,    the mv720p 1736x696 50fps mode, longest continuous recording ca. 1min. with average of 30-40 sec. continuous, has some corrupted frames, out of a 1200 frames recording it has 14 corrupt frames, another 300 frames recording has one. the bottom of all clips has a approximately 10 pixel thin line in all clips with 50fps. all clips have to be transformed in MLV App to 1,67x height.
3.,     the mv1080p 1736x738 50fps mode, continuous recording between 500 to 800 frames, no bottom pink line, ca. 3-4 corrupt frames per clip.
4.,     the mv1080p 1736x976 45fps mode, continuous for average 200frames, the beginning of most clips heavily corrupted, then ok, one clip without any corrupt frames, no bottom pink line. no transform required
5.,     the 2.5k 2520x1418 mode, 20fps, no corrupt frames, continuous (did 5min. recording)
     
------changed my canon video setting from NTSC, 1920x1080@24 to PAL and 1280x720@50
6.,    the mv720p 1736x696 50fps mode again , max 15 sec. record time, the thin whitisch bottom line still there, the many corrupted frames at the beginning not there anymore, got ca. 5 corrupt frames out of 500
------changed my canon video setting from NTSC, 1920x1080@24 to PAL and 1920x1080@25
7.,   the mv720p 1736x696 50fps mode again, longer recording time up to 20sec., whitish bottom line present, out of 1200 frames only six or seven corrupted
------same canon settings ( PAL and 1920x1080@25) - this didn't work, changed back to NTSC and 1920x1080 30p, broke the whole thing, reseted everything, using again NTSC and 1920x1080 24p.
 
    got the bench.mo from the experimental lua build, skips read speed, no bitmap file saved, write speed of the sandisk extr. pro 128gb goes up to 56 MB/s, one time read speed was reported to be 72 MB/sec - this would be great as write speed .... just kiding

used the august build before, which was good but more unstable, sometimes a complete clip was corupted, once or twice I've got a corrupted frame in a 2.5k crop rec. more difficult to get it running at all, now this changed dramatically, one can switch between the modes easily.

many thanks to Danne and others!

SUPER BLOOD MOON.

This development speed is insane and great. In current options, what would you recommend for capturing the super blood moon tomorrow morning? I have a 220mm F4.0 that I though I could use with the options with highest crop and best light handling. Or should I go for the 135mm F2.8? Dual iso I guess would be good too. Any suggestions for settings and workflow?

Does anyone have a recommended setting/resolution for least jello with best resolution?
The 4k resolutions are giving me serious shutter roll if I move even the slightest.

as far I understand this, try to use a shutter speed which comes closest to 180 degrees - like 173° or 191°.

thanks for the info Tullen. and good luck with it! hopefully there are no clouds
I would suggest to use the f4 220mm . also the 2.5k preset, and lower the framerate so You can use even 5.6 or 8 as aperture, to get the best sharpness of the lens, if this is not at f4.
dual iso maybe not that good for this.
hope to catch it here in Berlin too

@ AF-OFF

Thanks for the help. Any recommendations for how to get proper exposure. Since the light falling on the moon will change as the shadow disappears.

I would take care of the sensor saturation. like overexposing a bit rather then underexposing.
hard to tell, because the moon is still very bright, but I think there would be a better result if You recover highlights then shadows

Regarding motion blur. What shutter speed do you think is good? 1/125 or faster?

Will dive into this when I get more time. Goal to have solid none corrupted recordings. We'll see how far it goes...

You can compute it.
Moon does (approximately) 360 degrees in 24 hours, that's 12 degrees in one hour, that 720 arcminutes in 1 hour, that's 12 arcminutes in one minute, that's 720 arcseconds in one minute, that's 12 arc seconds in one second.
Now you lens have Field-of-view, and you sensor specific resolution, so you can compute what angle one pixel covers and then you can compute by how many pixels FOV shifts and then you want is to use time during which moon moves less that half of pixel.

@Tullen: Don't get overexcited about "super" moon. It's not that much a difference and blood moons are not that rare.

Guys, what settings would you recommend for shooting video with an 2x anamorphic adapter in front of the EOS M?

Looking for 1:1 or 4:3 in-camera aspect ratio, tops.

The new 1x3 pixel binning looks gorgeous, but I can't use 2.35:1, since after anamorphic desqueeze it'll turn into a terrifying 4.7:1


Regards.

@HappyBlack
You can use the mv1080p mode from crop_rec. (3x3 binning)
You can get 3:2 1736x1158.
But if you really need 4:3 set the horizontal resolution in the raw settings to "1600" and you'll be able to get "4:3" 1600x1158. (crops in a bit)

Probably your best bets

How does the upscaling work, its via metadata? If I open 1x3 DNG files in Premiere, it opens correct, but if I bring them into Resolve, they are 1/3 the horizontal resolution (1500something vs 4500something). Is there a way to work with Resolve, vs just scaling it up horizontally 300%? Or is scaling it up 300% basically the exact same thing as what Premiere is doing?

Upscaling works via metadata in cdng, right. I also saw that Resolve seems not to be able to scale automatically - whyever. But in editor there is a possibility to scale X axis by 300%.

I hate to ask as I feel like this is likely known information posted somewhere (I haven't been able to find it despite reading half of this thread and searching several times both here and on Google), but if I was to pick up an EOS M would I be able to use it as a webcam for streaming with a capture device and what would the limitations be?

I'd like to find something better than the standard Logitech C920 webcams used all over Twitch, but wouldn't have a huge budget to do so (I mean I can go up to a T3i and I know that should work, I'd just rather not). Plus, if I'm honestly, I did go to school for film and I've wanted a DSLR for years, but could never afford one. Besides, I would need something that can perform double duty like this.

I like the form factor of the EOS M and you really can't beat that price tag either, so if it'd work, it'd really be the ideal choice for me right now.

I know it doesn't support the capture over USB feature.
I am pretty sure I can get clean HDMI output with Magic Lantern from what I've read.
I've heard some things about the video output being locked to 1080i.
I wouldn't be recording while in this mode, I hear time out may be a problem?

I'm just trying to get a feel for this.

Applies to EOS M running experimental build "lua_fix", too.

Okay, so I can use a script to functionally kill the timeout.

Does that mean the other things I've researched are correct?

I think the saddest loss for me would be forced 1080i, I'm not quite sure how well trying to deinterlace the footage while streaming would work out.

And thank you for putting up with this odd question.

Can't answer that. Not owning an M and there are some pitfalls with M (mv720 ...) and some exciting new developments.
I hope dfort may have an answer about M's HDMI output in photo liveview and non-recording movie liveview.
