The tracks for Blender Sequences give the user a visual representation of the timing of the sequence elements. This is very important and should be visible at all times.
Relationship between tracks and Nodes
Every node is not necissarily a track, but every track is a node (or a combination of nodes) and should show up in the timeline.
Track Rules to consider
- A track represents a sequence or a processed sequence.
- A Mix node/operator is used to combine two tracks and is represented in its own track between them (current design)
- A track above another track takes precidence, when overlapping.
