Yeah this preset is a nice addon for c-mount lenses.
From what side vignette shows up ? I think from the bottom a bit evenly from left and right but only on really low light scenarios where i shouldnt even film.
And its a bit hard to predict all c mount lenses, some vignette earlier and arent super centered
#2
OK lets derail, so what esrgan model you recommend for 1080 mode 3x3 ? I dont want it to introduce ai artifacts and smudging typical for lots of esrgan models , i think my fav is  4x_NMKD-Superscale-SP_178000_G  cause it doesnt do weird crap but id have to test if it smooths out aliasing ...
#3
Id like to see more tests comparing 2.5k to 5.2k anamorphic mode to see whats the closest resolution detail, math is cute and all but theres several factors affecting outcome like scaling algo and skipping vs binning
#4
So from Your tests it looks like 2.5k is actually much better than 5.2k.. kinda how i thought about it all this time (anamorphic modes vs 1x1modes)... dont know what to think about it, did you sharpen something ?
Cause this is not what maths says and its clearly below 2.5k detail which concludes that i was right about the actual detail.

#5
Yes but no 24fps, i haev 2fps in fullsensor mode
Is there a specific address in 1440mode where i can up the height of the image ?
i have orange on 2500x1440 so i think in 1600x1600 il get green and i want 4/3 for 16mm look emulation, maybe even 1800x1800 would be recordable on this card

Your calcs are close if we would have 1x1 in all modes , its 3xwidth and 1xheight in anamorphic modes  which mess up the real width res and detail compared to 1x1 crop modes  so you cant simply calculate megapixels like this  and skip the fact that width is not true 1x1 pixel but skipped every 3 pixels which is sharper/aliased in some scenarios.

I should mention that skipping does not alaways look worse,  matter of fact it even can look sharper than actual 1x1 in some cases just cause aliasing creates fake sharpness.

Its like downscaling  whiteline-blackline-whiteline gradient with heavy blur where black meets white - when you scale down then you eventually get max contrast cause blur disappears and you see just single white-black-white lines which look like best sharpest image ever - but you lost detail and all the gray inbetween pixels by just skipping them.... in real world with ton of microdetails in far background this is  noticeable and it aliases or gets fuzzy in anamorphic modes , maybe not all the time as drastically but it is.
In big sensor cams and blurred backgrounds in the footage this issue might be not that important tho...

But yueah we all know it ... obvious stuff.

so i did quick comparison with text cause its simplest and easiest to compare without res chart, cropped the text from full image, all images were framed like this :

and i changed levels to match each one so contrast differences arent degrading or improving perceived sharpness.


It wasnt on tripod and imo should be done again but even with such poor example you can see that 5.2k indeed looks better than 2.5k.

So what would be real megapixel res, its hard to tell cause the formula is not takiing into consideration the fact that its every 3rd pixel not every pixel.

The result did surprised me a bit, 2.5k is not looking as good as i thought , might be how it really is but might be my error and not using a tripod, and 5.2k mode looks surprisingly good, almost as good as 3k so ill use it more often but maybe save as 4k

Of course it is true man, no 4k or 5k from canon m raw  has higher res than even crop 2.5k mode, 3k crop is best .
5k raw on canon m Is a bit above 1080p , do you math ? even if the resolution values arent higher and width is 3x3skip which is losing details compared to true crop modes .

Why would anyone think a value  1664 is bigger than 2500 ? 1664 is width in 5k mode, sure height is actual true 2268 but 3x3 binning of width resolution is degrading image compared to actural real 2.5k, and 3k crop blows all other modes away when it comes to resolution.
#8
zenny actual true res of 5k mode in canon m is lower than cropped 2.5k mode, its a bit above 1080p res , if you want highest res possible use 3k crop mode  and some wide +zoom lens.
I think using some fast lenses  made for gh cams and micro 4/3 sensor  on canon m in 3k crop mode will get you best resuts and highest res
#9
I can do 3k crop res and its more stable thats pretty neat.
Anyone knows how to do 1440p but square 4/3 ratio ? Or possibly even higher like 1600p square ratio like 4/3 ? I wanted to test the limits
is 1440 tallest in crop modes ?

General Help Q&A / Re: survey about sd overclocking
September 13, 2023, 09:33:11 PM
I dont know about the part of old cams getting cheap but  the expensive ones got cheap for sure, canon M for example actually costs more now than when it came out, i got it for 150euro with lens back in 2012 but now you wont get it at this price.
Canon 5DIIs are cheap now that i feel sorry for cameras and have the urge to buy them just cause theyre so cheap, unfortunately 5D has its own issues with colours in raw video , if it would be like M then id buy more.
And the thing about survey i get that its just a topic to get attention of the devs, so theyd see how many people are interested and can potentially crowdfund the development.

Thanks Walt, bought 256 samsung EVO +

Ok card arrrived, i am able to get 3k  in 2.40:1 ratio , about 40 seconds ,8-11bits, sometimes not even 5 seconds but its definitely possible  just turn off histogram as its the cause of recording getting cut off much sooner,3072x1286 res.
With 3k 2.35:1 im at 9 secs at 3072x1308.
2012 cam for 120 euro and 3k raw, its pretty incredible even if its crop , its amazing.
I like the 1440 res a lot cause its kinda like 16mm film , with C mount works nicely, i wish there was more resolution choices above 1440 like 1600 , so its square 4:3 like 16mm film footage.
#12
So.. i read some posts here about cards performance, anyone have the small ones ? DO they work as good as big ones?



Do they really work fine for video on M ? Whats the max res possible ? 3K crop at 24 works fine ?
Id pin this info somewhere about best /fastest cards that do work for raw video so there wont be lame questions like this in the future

I never touch the black/white levels, should I adjust them manually?
I dont mix 10bt with 12 bit presets, i have separate ones for each bit depth  cause you need to adjust black and white level to get rid of that red tint and get the most out of highlight recovery.
Yes even tho mlvapp has builtin defaults you should always try to test them to get the most despite of what everyone including me says, try to get them close .
#14
Ill try to tinker with this when gpt will be able to accept long pieces of code, with the speed ai is learning it will become better programmer than i ever could be
I can do simple edits to the code but figuring out all the branching between files in sourcecode and what needs what to work, its a long journey
I dont want to ask someone to do it especially if its not going to be useful for that person , my another goal is to also add a code to raw2mlv which would support taking external audio file into mlv container
But all of that would be solved if i would have exact reinhard tonemapping formula available in resolve
#15
Yeh im on 3090 and was on 1080, mlvapp is still very slow, resolve has nvidia cuda acceleration for 264 and 265, its a lot faster, minutes vs hours
so the pipeline is different from resolve and this suggestion wont work ?
#16
MLVApp is not using GPU at all, i can render the same scene in resolve in minutes, and it takes hours in MLVApp.
Id love to replicate tonemapped look from MLVApp in resolve when i import DNGs, i have some presets but they arent that close
By the way, i successfully used bing chat to code and fix code recently, so what part of mlvapp code, what file do i need to feed into bing chat so it would take a look and try to add gpu rendering using ffmpeg in mlvapp ?
#17
 :o Oh man, i tried setting hacks to MORE and used mlvlite instead of mlv 2 , and i can do even 3k recording now which was not possible, its fantastic
This is pretty amazing , even better than i expected.Also i can finally get 1920x1440 with c mount lenses
Im curious whats the highest crop resolution above 3k that people can record on fastests cards out there....
I agree with bringing back up/down for iso change so we dont have to touch screen at all when recording res is set
#18
Tried it on M, my cam is gettting very hot, enabed modules like mlv_rec,crop_rec and file_man
I cant even record one video at 1920x1440 where its about 40mb required speed cause it stops after few seconds.
pretty weird especially cause it works for others and it works great with previous builds.

So... quickly tried previous builds and yeah it works great as usual up to 2.8k but this one cant get past 3 seconds in lowest resolutions
#19
Can You make it work with dng from motioncam ? it records raw on android and converts to DNG
Heres one DNG file https://drive.google.com/file/d/1d6h1xWluv4aUYg3WMQmMAbp8Ter-2ARi/view?usp=sharing
#20
pinhole video is crap on M, you need very high iso to shoot with it, cool as one time experiment tho, try it, get disappointed and move on like most folks.
#21
Just compiled new version and theres VP9 export , Thanks !!!
I have a question, what should i change in the source so when i import folders with DNG files then i can mark 10 folders at once with shift or rect lasso ? Kinda how importing dng frames work( you can import multiple at once) but for folders.
#22
OK works, i  tried 2048 , and eoscard to set bootable flag and develop...
So , it boots about 10 seconds blinking red,

OK after a bit of testing 1024, i think this is too unstable , sure yo uget some seconds but then it drops and stops , stock settings are just more stable but lets others try it out
Boot times are killing me as well, takes like 15 seconds to boot into magic lantern and with 1024 mode is like 30 secs.
OK on 2048 its more stable but then its almost as good as stock format settings in cam + stock settigs have better boot time.
Maybe this would be better to test with 2.9k mode or 3k mode and 24fps but these are not in camera.
#23
I dont know man , it boots forever ( over 30 seconds blinking green ) and boots without magic lantern, how did you set bootable flag ? I used EOSCard 1.40 but it didnt help
#24
Hey guys , i just found this raw to dng converter so we can use raw dng files from a lot of different camera brands in MLVApp, its quite fast , no gui juts command line

At least one pass should be doable.
https://trac.ffmpeg.org/wiki/Encode/VP9

What mode is required? Lossless? Or constant bitrate? Or...
Well for me , id like to export VP9 encoded to resolutions like 8k cause ive got some 6k/8k from other blackmagic cams ( yeah braw works in mlvapp ) and settings that would allow them to work on youtube so 10 bit.Ideally id like adjustable bitrate so i could have own settings but i asked about it few years ago and you stated that its complex to add a box with customisable bitrate values so i have my own compiled versions when i bumped up quaity of x265 and h264.
Ideally - lossless, VBR,CBR and a box where we can set own values for VBR and CBR
