Hi
What's the masc method? Can you tell me in two words?
And what is the dark frames? Like in a astrophoto, denoising frames, right?
Just sorry for my english :)
RBF denoiser from MLVapp
yes, dark frames like denoising frames. you can read here from masc

MLVApp offers to reduce the static noise from your clips using dark frames. https://github.com/ilia3101/MLV-App/wiki#darkframe-subtraction

and YT compression if you upload to youtube

Have you tried uploading the same video to youtube but without denoiser? It will be interesting to compare. I found that youtube heavy compression algorithm acts like a denoiser to some extent :D

nice and clean.. 👍

53
I see.. thanks masc.

54
I see, thanks.
unfortunately DaVinci is heavier than premier on my pc.
I think rbf denoiser is enough for me at the moment.

55
hi bilal, sorry to bother again.. 😁

just comes in mind, I saw that color primaries etc. (in the image below) using BT.709 in standard recording.
is it possible to replace BT.709 with others in magic lantern? e.g. log-c or something else.


56
nice.. but what is the process?
for iso 1600 - 3200 in low light will get some noise I think.

57
Reinhard Tonemapped Iso 100 f/4.0 50mm, crop_rec 1x3 4K
I think 50mm fix lens has limitation in certain situtation, better in close up.

I think it using LUT
try this IWLTBAP LUT.zip

I got from this link LUT Generator for free or download here

masc,
in windows version there is no reinhard tonemapping function like yours


61
using masc method still got good result in very low light condition I think, plus a bit detail in the shadow that I couldn't see in actual condition.

this video recorded only use ambient light that goes trough the window at iso 3200 f/1.8 50mm, crop_rec 1x3 4K.
Edited in MLVapp using Dark Frames + RBF Denoiser export to h.265 4:4:4 2560x1280


62
I see, I just feel a bit jealous ha.ha. 😄



63
oh.. I see.

thanks. need more practice at it..

64
Thank you again, Masc.  I have downloaded your clip and will take a look.

Here is a Dual ISO clip that I have shot on the 700D:

https://we.tl/t-psETTga5hW

A sample .MLV is also enclosed.  I have downsized the clip to 2560x1440 resolution since the 5,2K file does not play smoothly on my PC.

nice.. I always get very dark image when using 100/800 with f/4 😊


65
👍

how do you manage the focus?
I have trouble when moving while using mf 😁

66
ok. thanks Skinny

and also at the same ambient and camera temperatures, if you can. for example, dark frame made with identical settings but with cold camera is absolutely different than when the camera is working for an hour or so. winter/hot summer conditions also should affect temperatures and noise patterns..

I did some experiments with timelapses (1-2h with 1..1.5fps) and if I record the dark frame before the timelapse, it worked good only with first ~1/3 of a video, and if I did dark frame after the timelapse (when sensor is hot) then the beginning of a video looks bad. So I couldn't decide what darkframe should I use.
But then someone suggested that I can export two video variants with both dark frames, and crossfade between them in editing software. Should work, but I have not tried it yet. Of course, for short clips it is not necessary.

I see.. so basically record dark frames before/after the shoot, right?

68
masc!
I noticed weird thing next to that person in your video. what is it masc? 😂


69
ok. I see, thanks masc.

in that web said..

Record with identical settings and identical equipment a clip with lens cap mounted. Some seconds are enough.

masc, do I have to make dark frames every time I change the setting?

e.g. record with iso 800 f/2.8 then I use the same setting with lens cap mounted to make dark frames, then I recorded other with iso 400 f/1.8.

thanks masc.

already subscribed your channel. 🍻

For most jobs I think RBF denoiser is good enough. Here my example for 5D3 footage using ISO1000..4000 + Darkframe subtraction + RBF denoiser + YT denoiser ( sry, compression ;) ).

wow.. impressive masc!

btw what is darkframe subtraction? thanks.

73
So, what do you think?  :) It will also look better with stabilization, because youtube is especially lazy when some parts of a frame don't move, youtube considers them static and just replaces with permanent picture. and it also increases quality of small details.
This is not scientific or something, just some of my observations. At least now I don't really care about small amounts of noise, in 1080 or less nobody will see it. Or, at least, there is no need for extreme denoising..

yes.. you are right.

interesting.. 🤔😄


75
oh really.. I'll try then.
