Newbie requiring help...

hi i am making a music video, and part of the aesthetic is taking footage and pixelating it like its fully blocky. I know that is not the right jargon but I am unsure how to explain it apart from pixelised or blocked out. Take a look at Gerhard Richter's painting here for a better idea...

How can this be achieved in tvpaint? Thanks!!

probably the Stylise/Mosaïc_FX would do the job ...

You may get a more interesting result if you boost your source material's saturation and contrast before you do the mosaic part.

I would start with reducing your footage resolution to a thumbnail size. then, pixels will occur more naturally.

is there really a difference when you want to "blockify" your 1920X1080 project
between:
-reduce project resolution to 192x108
and
-apply a mosaic FX of 10x10
?

There could be a difference because both effects could be calculated differently.

If I may take Photoshop for the example: I can reduce images by size using one out of three different interpolation methods, from nearest neighbour (pixel repetition) to bicubic (complex averaging of surrounding pixels). The results can vary drastically.

A mosaic filter could work with interpolating al pixels within the square, or it could pick one pixel's value and apply it to all.

Since I don't know the mathematical innards of any of these effects, I'd go for the look of the results. Whatever works, works.

(I found another way to do the trick: indexed palettes. I'd pick one image which contains all colours of the scene and change its mode from RGB to Indexed Colour. I'd save this palette and apply it to every frame of the scene. Thus I get a more homogene look over time.)

If you have After Effects, you can simply apply the mosaic FX.
nothing much to it.

Young Monkey's picture palette has had this trick built into itself for years with a single click and on top of it all, turns it into a dippy palette. I can never recommend his plugins enough times; this one and "Backup" but few seem to care to look into them. :roll:

I made this in a sec:
in a second too, but in tvpa (enter "20" for the block's size + hit "apply") :
to compare, left side = AE, right side = tvpa,
slightly different result, but not worse (maybe better because more contrasted).
:wink:
