idk if anyone has said it butā¦ DasGrain is up there probably more inportant than curvetool
and mmcolortarget

proper Grain tools for modern cameras and Color Spaces is a shameful oversight in Flame.

especially as almost every comp needs
ā Degrain (we have a good plugin but flames denoise should be the BEST!)
ā Regrain (no tools from adsk, we have some ok-ish matchboxes but nothing compares to dasGrainā¦

It would be great to have a UD/D node reading and converting data from UD/D node from nuke. Loading a *.nk and converting the data into flame would be a game-changer. ST-maps are outdated.

What about a matchbox that successfully mimics the FaceTime/Skype video calling with accurate bad signal sliders.

You already have one: In Color Warper ( CW) and it is great!!! ā¦not as a shade but as a node.
I often get mixed resukts with the CW when trying to match. Maybe im doing something wrong but it always goes way too strong in one direction.
curvetool in nuke is not a normal color curve tool, its very much mislabled but it can find stuff like the brightest or darkest pixel per frame and put out position data and much much much more.
its very handy for QC to find stuff like negative pixels or whatever, you can also average the values and get average luminance values per frame to do things like match a flicker in a plate etc. its more of a analyzer node that dripsnout data you can use downstream.

Same here, āCurve toolā if it is possible.
I really want to bring the Nukeās Curve tool function into flame.

Had this list in my email drafts for aaaaaages of shaders I wanted to try and make - some are def harder than othersā¦
- Warping colours toward 3/4 picked ones, like a gentle duotone/tritone(/quadtone?)
- A front/back mix that lets you go higher than 100%, so you can take any string of grading nodes and amplify the effect
- Flyās eye/distortion - did we have one of these already?
- Drawing rings/borders around an input matte (distance transform type thing, wouldnāt be super accurate like Photoshopās though)
- Sinc/Lanczos resizing - always felt Nuke/Baselight did a better job of this than the options in Flame
- Moving pond ripples generator to use as a displacement map
- Multiscale normals extraction for relighting - need an example to explain this but works way better than what the Bump Displace node does
- Voronoi-ing/hex tiling/texture splattering for making patterns that donāt repeat - good for regraining, I should remind myself how DasGrain works, I think it does something like that
Funnily enough I made not one but two Sparks long ago that did what Nukeās curve tool does - itās not possible to create animation channels in Matchbox but maybe I should take them time to rewrite them as OFX plugins? Match grading is another thing thatās really tough in GLSL because you need to look at the whole image at once not just individual pixelsā¦ (I eventually got fast at doing it by hand during the bad era of film DI when I had to match the dailies grades on hundreds of VFX shots 
having the RGB parade scope up showing both shots makes it way easier!!)

The multi tile thing would be great: like furnace pixel/patch texture.
The resize filter is a great idea. I do feel Autodesk would do us all a great service if they could update the filters in the software. @fredwarren
What do you feel is lacking? What isnāt working for you @johnt ?
@lewis found this link:
Was able to reproduce a bunch of it with your handy VOPS shader.
Thing that seemed to be lacking was emulating the modulo in an image.
The rotating and scaling of the vectors worked as expected but the modulo added variation procedurally.
Although I know there is an expression fir channels, couldnāt quite figure out an image filter modulo.
Know itās be possible w external dcc thru pybox, but was curious if you had any idea of a hack or workaround.
Your insight is much appreciated, as always.
Just one of many in the grateful community.

It would be nice to get some newer ones. I think itās the sinc one in Nuke is pretty good for resizing. Be nice if that would be included in all resize places in flame like action (diffuse), resize and UV matchbox. Oh and paint. Itās a real shame that we canāt have the tiled option like in desktop to prevent the picture softening so much. Especially when doing anamorphic. And then thereās lens distort nodeā¦thatās maybe a bigger conversation not wholly relevant to this thread.

I"d love to see a shader that matches a pull focus. Iāve been sort of doing it by tracking a point / points during the pull focus and linking the values to the blur. Im sure theres a better way to do this maybe using motion vectors but it would be a welcome addition for me. Mayching a CG element into a pull focus plate is always a pain in the bum.
Is it possible to do deconvolve in matchbox?
1 Like
I think it might in theory be possible but it would mad complicated, would be more suited to an OFX pluginā¦ idk though, I remember playing with the old Furnace DeBlur which used deconvolution and I couldnāt get much more out of it than what adaptive sharpening like Ls_Ash does 
ML stuff like Topaz Gigapixel works wayyyy betterā¦
Deconvolving seems to work well for astronomical stuff where they know very precisely how the telescope mirrors/wires/grids influence the softening and I have a vague idea that itād be good for fixing double imaging, like you get from shooting through glass - which sounds like it should be simple to fix but has ruined my day on more than one occasion
