I’m very late (6 years to your comment and 11 to the OP) But anyway, your first series of shortcuts only works for the keyframes literally visible in the timeline window. If you have more than about 50 layers, or a small enough window, this isn’t the best solution.

The best GUI approach I’ve found to delete keyframes of all layers would be:

1.…

Thanks for replying, Hector. But this doesn’t address the problem specifically.

Please, does anyone know how to either:

A. Lock the timeline view. (preferred)

or

B. Synchronize work area in all comps.

I’m working on sub comp within main comp.

I’m viewing main comp’s output while viewing sub comp’s timeline.

I set my work area (in sub comp timeline). I hit preview. Guess what happens?

The timeline view switches to main comp’s timeline and previews main comp’s work area, which is almost always set differently and irrelevant in the moment.

This has…

Correction:

comp(“notes”).layer(“Null 1”).effect(“Change Color”)(“Hue Transform”).valueAtTime(time-inPoint);

Solved it.

“notes” is the comp and “Null 1” is the parent layer. The code below goes into the Hue of the Change Color effect of every music note layer.

comp(“notes”).layer(“Null 1”).effect(“Change Color”)(“Hue Transform”).valueAtTime(inPoint);

I’m trying to color a sequence of layers based on a parent layer with keyframes prepared and aligned precisely to each layer’s inpoint.

The keyframes are sourced from a MIDI export, and I’m converting the MIDI velocity values to color hues in an expression on a parent layer.

I’ve tried a few different expressions, but I’m only able to offset… Read more
