Change comp FPS with an expression

Question

Hi,

I would like to change a comp frame rate (FPS) with an expression. The Frame rate will be from imported data so I just want to be able to set the comps FPS to either 23.975, 24 or 25fps. I would like all layers to be affected no just individual properties on layers. Just as if I had changes the FPS in the comp properties menu.

I see options to use the posterize time effect but I don't understand how to implement it for everything in a comp as required above?

Thanks for any help.

Nick

If you cannot add a keyframe to a property, you cannot control that property with an expression. You could write a script to change the comp frame rate. Fiddling with the time effects and time remapping will change the timing, not the frame rate of a comp or of an export.
