Compositor Modifier

Compositor modifier is powerful tool to create arbitrary effects. To use it, you need to open compositor editor and change node subtree to sequencer. Then you can add new node tree and use it for any strip. These node trees can be marked as asset and reused across multiple .blend files.

Node Group

The compositor node group used by the modifier.

The selector can be hidden by toggling Show Node Group.

Compatible node group inputs are automatically exposed as modifier properties, allowing effects to be adjusted directly from the Sequencer without opening the node editor.

You can mask each modifier to limit the area of the image it affects. This can be done using either a Mask or another strip.
