It took me while to figure out what "the other routine" means  ???
You were right, with SDR50 it works at 240 MHz @ 73MB/s  :D
Thank you.

Sorry, i din't made myself very clear.
My old card still works, 38 MB/s default, 58 MB/s at 160 MHz, anything higher drops to 20 MB/s.
So my question would be, what card should i buy to join the party and make it work at 240 MHz?

Hi,
two years ago, i thought that limit of my EOS M have been reached. Today I see how wrong i was  :o
Unfortunately, my Sandisk Extreme Pro 32GB 95MB/s doesn't work at 240 MHz, so I've been scanning forum for the list of compatible cards, but it seemed like mixed bag even with newer Extreme Pro cards (i've seen theBilalFakhouri's thread)and now i see this

Native write speed for EOS M is around 41 MByte/s in benchmark and around 38 MByte/s for recording.
Overclocked modes can do around 80 MByte/s recording with compatible cards. Until now we only have reports about Kingston Canvas being incompatible.
did i missed some post/thread with compatible/tested cards? Or every card with UHS-1 90MB/s write speed should work?

I made a (very) short test of 5K anamorphic flv mode and for the good measure i threw in Dual ISO.
I like the looks of it and also color/exposure flexibility from Dual ISO is nice, although it's more difficult to process.

I deleted everything from the card, loaded new version and now it works like a charm including replay.

New test build:
https://bitbucket.org/Dannephoto/magic-lantern_jip_hop_git/downloads/crop_rec_4k_mlv_snd_raw_only_2020Oct04.EOSM202_frtp.zip

Adresses 5K anamorphic frtp preset:

- Zooming with halfshutter while recording possible. While recording simply hald halfshutter for a zoom helping to nail focus easier while recording. Release button to get back to real time preview.
Bleeding edge tet build. Please report what works and if having issues. I look into it when I can.

OK, so zoom does work nicely, recording works in both full frame/zoom and alternating between the two. Unfortunately, when i try to replay record i get only blank screen and orange led blinking, after long wait metadata header (name+resolution+frame rate...) show up with frame counter increasing, but no video (only static image of other video on the card) i could go back to recording and when i try to replay for the second time, camera freezes completely (so, battery out). Every setting in default, only 5K anamorphic frtp chosen.

Holy smoke that was quick  :o
Downloading...

Thank you for the clarification.

i am aware that this might be stupid question, but...how do you guys focus in 5K anamorphic?
In 2.5K I can switch between framing and 5x zoom through Info button, but I wasn't able to replicate it in 5K. Is it even possible?
#10
I also noticed, that on close up shots (let's say 10 m max) there aren't problems with detail even now and footage is almost indiscernible from non anamorphic, it's slightly softer, but that may be even desirable.
#11
Well, sm105 is faster, i'd have the exact same comment (although i would use "dancing goalposts"). I admit that vercital aliasing wouldn't be much of a problem in nature. Also there is certain overall "mushiness".
I dig up my test shots from earlier this year, and while not directly comparable (different focal length) anamorphic exercise same mushiness.


#12
As a matter of fact at the beginning of this year I tdid some comparison shots between 2.5K and 4/5K Anamorphic and my inner pixelpeeper liked 2.5K more. Also I like simple processing like MLV -> Resolve -> video and I thought that I'd need to use MLV App as an intermediary...(it didn't occurred to me untit now, that Resolve knows how to process sources with non-square pixels).
And given the advancements since then I intend to do another round comparing 2.8K and 5K anamorphic.
As for fps, Resolve has excellent interpolation they call "Optical flow" which works really well as long as whole numbers are used as multipliers 15->30. 16 -> 48, 20 ->60, so that wouldn't be a problem (although it feels like cheating).
#13
Thank you.
Settings 2.5K 2.39:1 mode, 12-bit lossless, other ML settings at default. ML build from 24.3.2019.
Lens wise I had:
Canon EF-S 10-18 mm f/4,5-5,6 IS
Canon EF-S 50mm f/1,8
Samyang 85/1.4
+EF-M -> EF-S adapter
and from a friend i borrowed Camera Suction Cup Car Mount (all moving shots)
other than that I started with portable tripod but unfortunately almost immediately lost it (that's why most shots are handheld, though stabilized).

EOS M is tiny beast and it ages like wine :)
#15
Thank you. Flexibility of Raw image processing is unbelievable...as is nature in Norway.

Hi guys, long time no see.
This year i finally used Magic Lantern on my EOS M further from home https://www.magiclantern.fm/forum/index.php?topic=25354.0  with, what i thought was (feature wise) final version, clearly i was wrong. 2.8K preset and real time preview without penalty...it seems i'll have to carry it around longer.
Thank you for all the advancements  :)
#17
As every year I went to Norway for a bit. But this time I took my Canon EOS M loaded with MagicLantern.
I used MLVFS to provides files to DaVinci Resolve 15.

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

Report on crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Jan15.EOSM202
Unfortunately it introduces corrupted frames in all clips in both modes i used (1x3, 3K crop ).
On the plus side, there's magnified live view in 1x3 (stretched and somehow it show area of top right part from the frame) so you can alternate between framing and real time live view focusing (as it works in 2.5K mode).
#20
I used MLVApp, also my clips didn't have correct exposure, so some problems might come from it. I need to get ND filter, I've been getting overexposure at f/22!.
#21
Ok, so i tried some real world shooting in 1x3 dual ISO mode and here is the result
build crop_rec_4k_mlv_snd_isogain_1x3_presets_2019Jan11.EOSM202

Unfortunately I forgot,  that there are probably some extra steps in Dual ISO processing to avoid flickering...so there's flickering. Also conditions weren't pleasant (freezing, wind gusts over 70 kph) and it was first time i saw that CPU temperature was 0 degrees Celsius :o).
As far as corruption goes, i guess 50 % no problem, 25 % one or two corrupted frames at the begining or at the end and last 25 % unusable due tu mulltiple corrupted frames.
#22
You are clearly very patient :).
I agree with you in general, but in this case X axis is interpolated, so no information lost if no interpolation is done, Y axis is reduced, but given that i'm using dual iso, which (if i remember correctly) decreases vertical resolution by half. So yes, i'm losing some information (33 % on one axis?), but not that much and i'm not quite sure what to do with it anyway.
#23
Also, I don't know what beasts of a computer you have, but mine isn't built for processing 24 of 11Mpx frames per second  :o.
#24
OK, thank you both, i'm going to do the exports.
#25
Thank you for reply, but wouldn't be better to include multiplication in drop-down dialogue? This is a bit counterintuitive and also in my case slower, first upscale, then downscale, and i also kinda fear of introducing some artifacts created from interpolation (and there's lot of them in upscaled frame).
