lexar has more write speed than sandisk extreme but less read speed.

I mean using 1+2 hack on lexar has no different result..

#102
I tested on my lexar 1667x using 240mhz setting same result w/wo two more hack
write 96.7 mb/s
read 102.3 mb/s

preset 4K 1x3 12bit continues recording

btw, bilal.. what is the best setting for sandisk extreme pro 170mb/s?

thanks for the hack speed.
#104
is it save just to copy from already installed ML and paste to new card?
or I have to fresh install again in new card?

thanks.
#105
ah.. I see..
thanks Walter for the explanation..

No more wild thoughts, I accept ML as it is..

AFAIK, Transfer Function or "LOG" is only applciable to compressed lossy formats (like ProRes, H.264, H.265 ..etc), but not to RAW data.

I see..
can ml build add more format beside RAW maybe prores or something else better than just 8 bit canon recording?
so the log can be applied, I think it will be more versatile..

I hope.. 😅

nice..
why I don't see horizontal line when dual iso is off?
for 100/1600 usually more visible

dual iso off


dual iso on

For H.264 recording?
for mlv recording.. like other cam that use log to record video

I don't know if that possible also I don't know how transfer function works (even in MLVApp), but in general someone needs to understand Canon pipeline for image processing, if we are lucky enough it could be there some kind of "transfer function", but again . . someone needs to find from where the parameters could be controlled (assuming if there is a "transfer function").

If there isn't, I think it would hard, for processing speed there are hardware accelerators used for image processing in our cameras, and good luck with figuring out how to use them for our purposes.
I see..

btw, I found this on Wikipedia Transfer Functions in Imaging

hi bilal,
just curious, is it possible to implement transfer function like in mlvapp to camera?
I think it would be great to have log recording in camera..

thanks..

You forgot the user. If you setup low-iso/high-iso wrong, preview also doesn't work. But the problem can be one of the 3, or a mixture of all. DualIso is a difficult topic.

For the sun problem: it is not just a DualIso problem - google for "black sun": you'll find this problem with many RAW cameras, even ARRI and Blackmagic have (or had) this. If you like to implement and if have a nice idea: it would be a great new "RAW Correction".

ah.. yes I forgot  :P

it means that MLV RAW is not alone in the world 😁
#114
btw the problem is in the camera or mlvapp actually?

nice finding.. so dual iso will be better next.. 😃
#115
nice.. 👍
#116
oh.. I see
maybe masc can figure it out.. 💡

About the pink horizontal lines on dual iso, I've been experimenting and it seems like the white level is set too high on the high ISO part of the image. If I set it to half of the value (white_bright *= 32 instead of 64 on dualiso.c - diso_get_full20bit), in most cases it fixes it completely or at least it gives a constant pink highlighted area, like on the example below.
I'll experiment a bit more, but maybe someone who actually understands the math behind all this can think of a reliable solution that works on all cases and it doesn't affect the general quality. Maybe a slider to adjust white balance individually for the bright and dark parts of the image when dual ISO is selected would help?


for pink highlight I check the highlight reconstruction to make it back to white

my dual iso test..
I use iso 50 tweak -1 EV (canon iso 100)

no adjustment


after adjustment (w/o noise reduction), max detail I can get from my lens capability.

other sample before (just dual iso on) small pict and after adjustment in the same room as post above, it still gain some detail but the noise is visible if I rise exp. more.

hi 70MM13
I tried to figure it out by using dual iso and iso tweak in camera to -1 EV is equal to iso 200 (canon iso is 400)
no light in the room and quiet dim just using light source from right side windows that 4 meters away to the object with dark background.
I tweak a bit in mlvapp as the result below..


what do you think?
actually if I push a bit more exp. the noise is visible. 😅
#123
i see..
in their site pytorch.org I saw that you don't need cuda if you use libtorch for c++
but I don't know technically if it is applicable or not.

btw, I found this cuda for macOS maybe it's usefull.

ah sorry you don't have cuda GPU.. 😅

hi masc..
is it possible to implement this Video Restoration Transformer in mlvapp?
I search google that pytorch can work with c++
