Free Final Cut Pro plugin: Alex4D Opacity Gradient generator

My free Final Cut Pro X generator produces areas of colour with an opacity gradient.

Here are the controls:

If you connect the generator to a clip…

…it will overlay the colour:

The area of colour can itself be a gradient by checking Two Colours 

Start Opacity: 75%, End Opacity: 100%

The gradients can be radial:

L: One colour, Start Opacity: 100%, End Opacity: 0%
R: Two colours, Start Opacity: 80%, End Opacity: 100%

You can control the centre point of the opacity gradient and colour gradients:

L: Opacity Centre: 10%,  R: Opacity Centre: 100%

L: Colour Centre: 80%,  R: Colour Centre: 20%

  4. I was inspired by you to make something similar to this as an ND and polarizer! Totally worked Im excited to see you went the same route! Yours includes some controls I missed thanks!!!
