Nodes Distances

In the following pictures, the parameter is underlined in one color and then in the same color a marker in the node editor, which shows what the parameter is used for.

Timeline Types

Add Nodes to Timeline:
The node groups, which are located in the node editor, are duplicated and randomly attached to the timeline. This is a great feature if you want to make an audio visualizer for example. The advantage: You can give each node its own parameter settings.

Add Nodes to Timeline and Only Attach Nodes:

Nodes are not duplicated, which results in faster performance. In addition, you have fewer nodes to worry about.



The "Add Nodes to Timeline" option is disabled:

This creates an empty timeline. You can link your nodes yourself.

Timeline Options

Switch Nodes

Frame Switch:

The frame at which input 1 is changed to input 2 can be specified.

Frame Switch Repetitive:

It can be specified after how many frames the input is changed. It is always changed back and forth between input 1 and input 2.

Blending Switch:

The start of the crossfade can be specified and how long it will be crossfaded.
This node is not present in the geometry nodes because geometry cannot be blended.

Blending Switch Repetitive:

You can specify how long Input 1 or Input 2 is held, how long it is then crossfaded, and an offset. It is continuously faded back and forth between input 1 and 2 with the entered parameters.
This node is not present in the geometry nodes because geometry cannot be blended.



Switcher:

This node was originally made to switch between inputs with music.
It mixes very well with the Audio Importer nodes.
The input is, for example, music, or frames, or whatever. The intensity multiplies the input if a very weak signal is used. And the Threshold specifies when to switch between the inputs.

Performance Guide

If performance is slow, it's probably due to Eevee's shading. Just switch the viewport shading to solid and everything will run fine.

You can experiment with the Timeline Options. If "Highlight active Frame Switch Node" and "Mute Unused Shading Nodes" is set to inactive, the add-on does nothing. However, the switches still work. They are just no longer highlighted.

The more nodes there are, the harder blender has to work.
But to have massively less nodes, you can activate "Only Attach Nodes", so that the nodes are not duplicated, but only linked.

The Node Editor always needs power, even if the Node Editor Timeline Add-on is not active. To test if the performance is slow because of the visible nodes, you can simply hide the nodes by selecting another object or changing the screen.
The add-on only takes care of visible nodes for the best performance. Unless there are timelines in the shading and "Mute unused shading nodes" is active. However, this does not need much power.
