RGB Only One is a software that assesses each pixel component and only allows the one with the highest value to pass through.
With additional controls to re-lighten the clip and limit re-lighting to the winning channel, you have the option to preserve the original brightness while eliminating white and redistributing whiteness to the winning channel. The plug-in also comes with an area of effect tool, allowing you to resize or reposition the rectangle that the plug-in affects.
To adjust the effect's opacity, you can use the slider provided, which gradually allows more of the original clip to shine through. RGB Only One is a great plug-in for those who want to experiment with interesting color effects.
The plug-in is easy to use and requires only iMovie to run. Give it a try and see what kind of unique visual tweaks you can add to your clips.
