Like this:

eval(marker.key(1).comment)

HI Dan, I must be doing something wrong cause when I type that expression in the layer marker’s comment field it doesn’t show up in the timeline as the result, but just as the code I input verbatim.
Help

Maybe I misunderstood. That expression goes in the property that you want to have execute the expression in the marker comment. For example, if you put the expression in the layer’s opacity property and put

time * 10

in the first marker comment, you’ll see the opacity increase with time.

Hi Dan, well what I was trying to do was get the comment itself (that you see beside the layer marker) to update based on an expression. Maybe that’s not possible?

Ah, yes. Sorry – you can’t do that. In general, if you can’t keyframe it, you can’t apply an expression to it.
