I see masc..

thanks a lot. 🍻

Open the MLV sample in MLVApp and press the Info button.  You will see all the camera settings the file was shot at!  Then you can use these same settings to film your own tests at 18W LED lighting.  Compare your results with and without Dual ISO and  post them here.

with dual iso 100/800 f2.0 crop rec 1x3 4.5K

without dual iso 800 f2.0 crop rec 1x3 4.5K

those are better than mine before 
I don't understand why.. lol

Nice and very informative video, thanks a lot Zeek.

I have a question.  The camera needs 7,4V for proper operation.  How do you adjust that voltage in your power bank and how do you prevent it from outputing more than 8,4V which could damage your camera?

I think he use this..(dummy battery) like mine for 700d.

oh I see.. yes, sir.

masc..
how dumb i am , I just realized that denoise feature in mlvapp is better now..

I found this link https://github.com/clausmichele/ViDeNN
what do you think?

btw I'm curious to ask, why stabilize feature only use h.264 not others format(e.g. prores)?

thanks a lot masc.

Of course it applies to low light too!  But you seem to prefer asking questions instead of testing by yourself.  Just follow the procedure that I described in my previous post and check by yourself.  It will take you just a few seconds.  18 Watts is a lot!  You should get an excellent image with that much light.

sorry for that, it's because of my past experience ..  😁

Here is a short room sample at 100/800 that I have just shot for you:

https://we.tl/t-QmeuJot9E1

The light bulb is just 11W.  Post processing and downsizing to FHD was done in MLVApp.  A short sample of the original MLV is also included for you to see all settings.

thanks IDA_ML.. I can't believe my eyes, I have to try soon haha..😂
unfortunately the setting you told is not included.. but it's ok.

...no idea - I think yes. But that is what I mean: Someone should play with that and try out. ffmpeg is in MLVApp path. So just take any video clip and try to play with it in command line terminal.

thanks masc, I will try to find out.

thanks for your advice IDA_ML

does this also apply in low light conditions?
I ever used dual iso in room light (18w led bulb) at night but the result was almost black.

is it possible to preserve sharpness while denoising?

Commandline based is better. But those apps are Windows only... did we have "post export scripts" in Windows? I know we have that on macOS. And remember: this works post export - that means you encode twice (and this will be at the cost of quality).

If another denoiser would be on your wishlist, you could do some research for ffmpeg denoisers. I know there are multiple different denoisers included in ffmpeg. If we know the exact commands and the meaning of all the parameters, we could try to integrate this (best with some presets, so the user just selects something like (hard/soft/...)). And here we encode just once. It could work for all ffmpeg export codecs. I know "Handbrake" offers these denoisers.

that's great.. can it export to maybe prores 422 in mlvapp? 

OFX is extremely difficult - at least too difficult for me. If someone can help integrating that, please let me know. I tried that in past and gave up after a few weeks.

oh ic.. how about the first link I gave "batch_denoiser"? not ofx based I think, it use command like in mlvapp, here is a guy talked about it in this forum https://www.dpreview.com/forums/thread/4461481

about mvtools I google and found this links:
http://avisynth.nl/index.php/Main_Page
http://avisynth.org.ru/mvtools/mvtools2.html
https://github.com/pinterf/mvtools
and this one will useful too if it can be integrated with mlvapp https://www.svp-team.com/

nice and clean, how to implement in 700d? I got very noise video when try to shoot in room light condition. with dual iso I got very dark barely can't see anything in the video and if exposure increased the noise is very bad

@ML700D: do you know any free and easy API? What kind of plugin?

denoiser I think, I found this freeware but not try it yet. https://bit.ly/32jqXZG

or like this one https://github.com/NatronGitHub/openfx-misc (OFX plugin)

if mlvapp could implement existing plugin (third party?) like in premiere pro or other NLE it would be great I think.

nice video bro..
I feel like I'm in the limbo.. lol

Try chroma smooth 3x3.

@ML700D

This problem is related to focus pixel interpolation algorithms inside MLVApp, it doesn't clean all focus pixels with Dual ISO clips, sometime it produces more focus pixels, best thing to do is as Danne suggested to use chroma smoothing. also trying different RAW debayer algorithms might help reducing these pixels.

I've tried it but it doesn't work with chroma 3x3 but yes it's a bit reducing when using log profile.
it's a bit strange, sometimes it's there, sometimes it's not even though I use the same setting.

ok. thanks bros..

hi bilal..
I found that if i record at a distance this is what usually happens and it didn't work using fixed bad pixel

My short video creating "Dramatic Look" in MLVapp 

I made new video titled "The Color of Life.." lol
in this video I tried to color corrected using some features in MLVapp, the result is just my personal taste.
as usual, I use 16:9 UHD 1x3 setting from ML bilal's build with 10 bits 25fps. all outdoor video recorded with 50mm-f/4.0 iso 100 in camera.
ML RAW exported to 2048 x 1152 ProRes 422 HQ after edited.
in premiere pro I just re-wrap the clip after given some transition, effect and song.. to 422 again and then upload to youtube with 3 Gb size lol.. but it took less than 30 minutes I guess.
some clip is repeated just to fit the song..  here it is: (set to HD for better view)

My findings, from worse to best:

bilinear <- worse
bicubic
lanczos
avir <- best

Speed, from fast to slow (on CPU) :

bilinear <- fast
avir
bicubic & lanczos <- slow

mlv app using avir right? thanks for your infomation.

"the best" is personal preference I think..
for me MLVapp is more than enough, I use 1x3 binning too with no problem.

here is my sample video that I made using 1x3

ok. this is the setting I like so far
ML Raw 16:9, crop rec UHD 1x3
MLV app 2048 x 1552 ProRess 422 HQ

I think this gives more flexibility in editing, here is my sample video:

@ML700D

You can play with Crop mode V2 and see what max FPS you can get at what resolution and binning mode , 1736x970 3x3 @ 50 FPS is possible but can produce corrupted frames in lossless compression, and requires high write speeds (not practical)

AFAIK 1736x864 3x3 @ 50 FPS (maybe 48 FPS) is usable with lossless compression, might not be continuous. Using 1x3 binning mode with High-FPS would lead to very wide aspect ratio.

I ever tried using crop mode V2 but still confusing with the setting and get pink zebra at live view sometimes, so how to calculate it properly? thanks.

cool, nice video..

just share my noob experience.. lol
I use intel celeron, it takes 20 minutes to render 2K video with 50 seconds duration 
but before this, it was impossible.. so I googling then found that h.264 is bad for editing
and then I change to ProRes 422 in MLV app and get much better with 2K in editing.
for uploading to youtube I convert the video to mp4 with h.265 codec.. here it is:
