A free Final Cut Pro for Mac effect that blurs, colours and changes the contrast of a rectangular part of a clip.

Use it to add modern-style (in late 2013-early 2014!) layering to your video when you want to overlay logos, text or other clips.

Uploaded Friday 30 August 2013


This free plugin is for Final Cut Pro X for Mac 10.0.6 and newer.


Thanks to Y-Love and Matt Davis for the use of their interview footage.

Apply this effect to video clips, generators and titles and use the on-screen control to choose the position and size of the area you want to blur, colourise and change the contrast of.


blurred-coloured-glass controls

Blur ranging from 0 – no blur to 100 – very blurred.

Colour choose the colour used to tint – if the value of Colour Intensity is greater than 0.

Colour Intensity how much colour to add.

Brightness changes the overall brightness: 1 – no change, less than 1 darkens, more than 1 brightens

Contrast increases or reduces the contrast: 1 – no change.

Saturation increases or reduces the saturation: 0 – no change.

Corner Roundness controls how round the corners of the area to be processed: 0 – square, click and drag the number for larger roundess values, which changes the process area from rectangular to oval.

Centre choose the location of the process area – drag on the on-screen control to set this more precisely (unless you apply this effect to a Title or other generator with on screen controls.

Width + Height controls the size of the process area – drag the corners of the on-screen control to set this more precisely.

Feather values greater than 0 soften the edge of the process area.

On Screen Control the position and size control changes the brightness of the clip when the clip (and the effect in the inspector) is selected. If this distracts, click this check box and then deselect the clip. When you next select the clip, the on screen control isn’t shown, but you can still set values for area position and size in the inspector.
