Feature Requests: Soft Ranges & Blend-If Function

Would love to have the ability to introduce a soft range on either side of the Luma Range in the Luma keyer (and other keyers) independently of one another. Perhaps option-click the endpoint to split it and drag to set the soft range size, just like in Photoshop.

It would be amazing as well to add a "Blend-If" section inside the Merge node, again using the same implementation that is found in Photoshop. This kind of additional blending option adds another huge level of control over the blending of two images and can many times eliminate the need for a separate Luma keyer or mask node for example.

A year ago I implemented a basic version of Blend If using a Custom Tool. The maths is pretty simple and I doubt mine is using the same maths as Photoshop - theirs is probably more sophisticated. But this might get you started if this is a feature you need.

The code is provided and described in this post on the We Suck Less forum.

Couldn't you just have two luma keyers where one is inverted? Use the gamma to control the softness of each. That would match what Blend If does?

Simon Ubsdell has recently posted a tutorial for making a Blend If macro, which exactly recreates the Photoshop tool. It's far better than the simple tool I posted earlier; mine was just a quick hack and doesn't correctly replicate Photoshop.

Here's the tutorial, which includes a link to download the macro he made, for use in Resolve Fusion and Fusion Studio.

As a matter of fact he created this due to my suggestion! He's a champ!

Better yet, just use a CCv to make the softness fully customizable.
