don't use dnxhd (unless you really need it)

[andy kh]

So footage is 1920x818 and you export to 1920x1080 with a black border?

i get black border because i think premiere pro is intelligent. it knows the aspect ratio of my video and  maintain the height with balck border without strecthing my video height regardless of the codec or height i set

[andy kh]

Try match sequence setting. Pretty sure it won´t export dnxhd.

dnxhd comes with presets. there is no option to change to match sequence settings. what im poiting out here is that i can export using any presets wihout stretching the height in resolve/premiere pro

FFmpeg is very versatile. It can do almost whatever with your footage. And pad output is considered basic. But it might be a cool thing to add in Mlv App. Here are two links:

@masc , I had a problem with 50D clipping hi-lights & turning them pink , I was testing UHD(3744x1080)
I shorten one of the mlv to 50 frames (240MB) on my Google drive if you would like to have a look at it

I had no problem with Adobe A.E. to bring back the hi-lights , here the post of the video from A.E.

Known issue for cameras other than  for 5d mark III. Decrease the white level in raw correction

Known issue for cameras other than  for 5d mark III. Decrease the white level in raw correction

Ok , Just tried that and no , it clips even more .

[Danne]

In this case it´s enought to pull down exposure and go from there. Reminder. Mlv App is not acr for good and worse:


Interesting, it´s not possible to increase white level in this mlv? Meant to be?


EDIT:
some fast color correction:

Huuu?! This has nothing to do with 5D3. Can and will happen with any camera, also with 5D3.

Huuu?! This has nothing to do with 5D3. Can and will happen with any camera, also with 5D3.

my bad. bad in explaining. i mean to say there is no need to adjust the raw white level  for the 5D mark III. i can confirm this as i own a 5D now. i can now shoot in any bit and need not touch the raw white level like i had to do for 70D if i shoot in 10/12 bits

[ilia3101]

Reddeercity has pointed out a real issue, highlight reconstruction does not help where these flowers are clipped, luckily the flower is pink anyway so the pink clipped parts blend in. Took some time for me to notice this. Highlight reconstruction only works well for neutral colours, I have tried to fix this before and failed. I think I know how it's just difficult to make it work.

Tried to match(/exceed) ACR:




@Luther thank you!

[2blackbar]

Interesting is that when you switch to something else than "use camera matrix" then pink /cyan highlights disappear(turns ok and pink is turned into proper bright/ white tone).
When you use standard instead of tonemapped or film - pink/cyan frame turns ok.
So it is possible to do and MLVApp already does this properly but not in tonemapped and not when using camera matrix, maybe merging two methods( camera matrix and uncolorscience) would give proper results for highlights while preserving amazing colours of camera matrix method.
Last image with white/pink lines is the border where pink turns cyan, you cant get white but sometimes cyan line next to pink colour will cancel each other which looks like white, when you go with slider down even more then eventually cyan takes over , when you go up then magenta/pink takes over that area.

So why dont I use something else than "use camera matrix" you ask ? Because i love the colours on it that look like CMYK film.

[ilia3101]

Nah it's all the same method. (Unfortunately )

Using camera matrix creates more accurate colours, but it also happens to saturate many colours including pink, so the pink highlights are more noticeable.

Standard curve clips off many stops of dynamic range, so it may cut out the pink highlights, but they are still there, just not visible as they may be clipped to white. I don't like the clipped look from standard so I rarely use it.


The horrible saturated colourful highlights you demonstrate will be gone in the BetterProcessing branch once it's completed.

[2blackbar]

So maybe something like another correction for pure white would be useful , cause pink/cyan should be white, they fight over this area.
Also standard is as saturated as film/tonemapped and looks quite similar but its pink/magenta treatment is much better than tonemapped/film.
I use highlights slider turned all th way down with standard and it preserves all highlights even better than tonemapped/film( makes them bit darker) but i dig the contrast(highlights rolloff) in tonemapped/film more than standard.
Tonemapped vs standard and highlights restored on both

[ilia3101]

"a correction for pure white", I could do that: a separate white balance setting for highlight reconstruction. This would fix any pink/cyan highlights, but it's another slider to adjust each time. So I want to make this automated.

But if anyone reallly wants it it could be a temporary solution.


Also you comparison shows standard looking better than tonemapped, which is interesting, but see how they compare when you pull the exposure down a few stops.

[2blackbar]

I posted another one while you answered, tonemapped vs standard.Standard has diffrent highlihts rollof and contrast than tonemapped, but i prefere tonnemapped/film (both are very similar) at this moment, its a matter of taste maybe.Just looks more like film.
Without highlights slider moving down standard does have highlights more blownoff than tonemapped like you described but testing them with highlights brought back produce similar results, darker/more contrasty on standard.

[ilia3101]

Thanks. Well it is interesting that standard preserves highlights better. Not sure why, nothing about it means it should. Probably something to do with perception.

[2blackbar]

I agree its perceptional, Id say technically its similar but contrast in standard makes the highlights darker a bit.

Definitely WANT  It would save a lot of shots, or somethng to switch on which would force #FF00FF or #00FFFF to pure white or slightly gray , or change saturation to 0 from these two particular colour tones.
Fixing bad pixel has detection for red pixel so maybe fixig cyan/magenta could have similar, theres no magenta or cyan that saturated in real life.
It is dirty solution but so is "highlight reconstruction" , which IMO should be always on.

The camera matrices, do they give output with absolute colour, D65 is equal to D65? or is it something like D65 is at D50, I seem to remember andy600 mentioning that and it has been a thought in the back of my mind ever since. (I am so confused about this!!!!!!!!!!!)

Another thing.... Let's say processing will use multiple gamuts for different stages (it will, three to be exact) - some of these gamuts may have a D50 white point, some D65, and some approximately D60. When converting between these gamuts inside of processing, should the white point be adapted (relative transform) or should it use an absolute transform? I am thinking relative would be better, as it avoids white shift in some adjustments like saturation.

And: Does anyone have links to info of how perceptual gamut transforms work? (implementation, not just an explanation of how it looks)

I have no idea about those questions Ilia. In my mind I always thought that color conversion is something complicated and often not precise, so the simplest solution should always be the best one.
I noticed you seem to be using XYZ and then converting to other space, right? For example, I see you got the ACES matrix from here (XYZ-to-AP0). Wouldn't be better to just use right away the intended color space?
Might be a good idea to request help on ACES Central. They might have the answers about your white point questions.
