Why Speedy Shaker?

Simply put, because it is a multi-layer mixer/shaker/blender on steroides without actual steroides 😜 And it is fast! Like really fast.

I wanted to have a tool that provides the same functionnalities as Photoshop/AFter Effects but expands on them with deep integration in TouchDesigner with the minimum CPU/GPU footprint.

This component is based on the super-excellent GLSL mover-comper by archo-p that he made available on TD forums. Thank you!

I wanted to expand it extensively to include an essential kit of color-correction tools as well as some extras. The GUI was made with custom parameters so it would be self-explicite.

Please, bear in mind it is version 1.0 and almost certainly quite buggy. At the end of this readme there's a list of features/bugs to expand/debug.

So, let's get on with it, shall we?

What can it do for you?

1. Up to 16 layers (not a physical, but more practical limitation) with full control on transform/scale (from original component by archo-p)

2. Pixel or fractional translate (from original component by archo-p)

3. Top Left mode origin (from original component by archo-p)

4. Background can be TOP or color

5. Resolution can be set from Background TOP (no translate/scale)

6. Matte per Layer

   • can be alpha or luma matte
   • can be inverted
   • can be translated/scaled
   • lower and upper range that alternates how matte alpha reacts (kind of contrast control but for matte)
   • can be linked/stretched to layer
   • if non-existent - considered as alpha=1

7. Per layer control:

   • tint to color
   • basic bloom with advanced control (it looks pretty bad now, more like box-blur because I wanted to use only 1 pass instead of 2-pass gaussian blur). For now it works as pre-effect, before any color correction happens.
   • blending modes - these are based on Photoshop Math (25 modes)
   • blending strength
   • level - alpha control
   • perceptual desaturation - truly black&white filter based on color weights
   • brightness/saturation/contrast/gamma

8. Advanced layer control:

   • on 'Layer control page' you can change the order of layers
   • Solo/Mute

9. GUI Control:

   • Add/Remove Layer
   • Reset Layer

That's it folks!
