Only artefacts in preview, not the actual recording.

Danne here is the sample with the blackbar when using 2.5K 2.39.1 and 24fps override. The problem comes when using overide. Iam using our version from 07dec.

Don´t use fps override or go into fps_engio.c and modify code.

That 10 bit mode is working fine, i tested today, fps override screws up anamorphic mcm mode so sometimes its better not to use it, without it motion blur looks different.
I had black bar on side recently in 2.5k mode when skipped left or right (dont remember) too much from one side, changed it back and it was fixed.

Hey guys
Just wondering if I can go past 3200 iso
There is a few occasions I need to go past and it says max iso reached

Why is this and can I change it

Turn off the iso buttons under customized buttons.

No pun intended but I highly recommend to refrain from using ISO 3200 or higher on the M even w fast primes and enough light.

Maxing out @ ISO 3200 is like saving you from having a horrible nightmare with pesky colorful dots dancing around on your shots.

Thanks, @Danne for this wonderful safety limitation w the ISO climb. They do make our cams feel much more fluid and dandy!

Out of curiosity i did comparison test between different modes , and i did not extect such a big difference, 2.5K mode wins

Im surprised how little 5k anamorphic gained compared to mcm 1080 upscaled to match the size.
Ill try it again but with smaller letters
Just dont confuse this, regular mcm rewire is upscaled thats why its not that sharp.In original size it looks better.

And what about aliasing comparison? That's worse than anything else  :P

@2blackbar: was expected... 2.5K: we use all pixels (1x1), 5K anamorphic: we use every 3rd pixel (1x3), 1080p rewire: we use every 9th pixel (3x3). But if you compare a similar field of view, the result will be different.

This is comparison when downscaling 2.5k and anamorphic 5k to 1080p
There is big advantage when scaling from 2.5k but scaling from anamorphic is not going to make big difference

Its interesting, i thought anamorphic gives much more resolution, at least perceived resolution but looks like it doesnt but when compressed and all, its better to save 1080 in 4k resolution to preserve all detail thats lost during compression.
Aliasing doesnt bother me much, we cant do much about it.
And yes i did focus precisely and did not change anything between takes, png frames to gif.

1080mcm upscaled to 5k , here you can see more difference, text is probably too big already, ill test on smaller one thats barely readable on anamorphic.

Not sure what you are saying. Are you upscaling mv1080p mcm rewire to 4k and compare it with anamorphic? I haven´t seen one comparison that holds up agains anamorphic. Yes, anamorphic is a bit softer but you gain aliasing free footage. mv1080p is sharpness bogus in comparison.
2.5k 1x1 wins hands down, but I think anamorphic is the perfect compromise. Remarkable that it´s even achievable. Thanks to a1ex...

EDIT: Looking at your posted images it´s clear that aliasing kills the mv1080p completely. I mean you can upscale both but only ana holds up imo. It´s even sharper and you can even see the polish text much better than mv1080p.

Yes  Youre correct and no aliasing is the main advantage in anamorphic mode.
Yes anamorphic is nice but i would probably not keep it in original resolution, maybe in 2k, it has more details than mcm thanks to no skipping in 1x3 , not three times as much but a bit more.
I wanted to finally see how much resolution anamorphic gains in its 1x3 mode when its practically 1x1 readout and binning.
But i do bear in mind that aliasing creates fake resolution that might appear sharper but its just harsh aliasing edges creating fake contrast.
What i mean by saving 1080p is that when i compress it i tend to lose some detail compared to original tiff or png exported frames, when i export in 2k ( upscale 1080)then details has higher chance of surviving in higher resolution.

Yes, it´s a compromise really. But I think it works both for blow up like 4.5k or scaled down too. Softness creates cinematic feel almost. But it´s very much personal taste.

I still think the comparison is a little unfair, because you look at crop, which has the same factor but different resolutions for each mode. It is to be expected the 1080 looks worse than 3x better 5K ana, looks worse than 3x better 1x1 mode.
If you want to use 2.5K in real world, you need extremely wide angle lenses, to get a normal field of view. I think in your comparison you always took the same lens and same focal length. Right?
If you found 3 different focal lengths (which all are sharp from lens side) to make all 3 fields of view the same, 5K will be very close to 2.5K mode, while 1080p won't have big chances.

Yeah, i checked bluray stills from many old movies from 80s but it is not sharp, especially telephoto lenses are soft, there is resolving resolution to a lens, i thought glass is a glass, there is no limit but yes it is, new lenses are sharper than lenses from 80s and 70s, wide lenses are sharper than telephoto , i mean telephoto wide open or stopped down once.
First color films from around 1930 dont have that contrast edge like today but it looks so nice and natural

4K is already too much for those old movies mostly because of the lenses they used, they sit maybe around 2.5k and 3k.

mcm ana and rewire 1080 comparison is unfair but even then its quite close.Yeah i wanted to avoid different lenses and different scaling algos, i might do that eventually but i kinda know now what to expect.
So maybe one more test , scale up 1080p and anamorphic to match 2.5k by field of view and resolution
This result i like much more, same dngs but i bumped up contrast by the same amount on mcm and ana 5k in mlvapp

on second gif i can make out some small font words on ana, on mcm no chance, about 12-25 pixels tall font starts to disappear

@Danne

Will definitely give this a Christmas look  ;)

But if I understand things correctly, you can't get FLV, i.e. full sensor at 14bits out of an EOSM, as you can with a 5D3.

You can get 4k and also full sensor readout in anamorphic mode. Anyway. I will add this feature to the 5D3 as well, give me 20 minutes.

Lol, not *quite* as handy as a monitor but certainly one way to circumvent potential dropped frames and other external monitor issues:

I'm hoping its current popularity will spur the development of a less 'diy'-looking version.

Would it be possible to obtain a flip screen with some kind of extended ribbon cable and 3d printed housing for the lcd? Or maybe taking the lcd from a the m3?  :'(
