Dynamic link between Premiere Pro & After Effects

[Alex Udell]

Hi Rachel…

When you do a replace the clips like you have…

It’s helpful to think of the clip object in the timeline of PPro like a window peering into and see the resulting frames of what’s happening in the After Effects composition at the corresponding time.

So the Obejcts themselves: the clip in the Ppro time line and the layer in AE are two independent objects. Trimming an AE layer will not shorten or lengthen the corresponding clip in PPro….

Think of of doing work in AE and then just passing those resulting frames out where PPro can pick up the resulting frame and show it in the Ppro timeline.

If you trim a layer shorter than before…PPro will see black where those frames were, because there’s no frames feeding the clip obejct at that same point in time.

If you shorten a Comp in AE, PPro will likely show you diagnol lines (I think) on the timeline, because the comp object in AE doesn’t have enough “media” to fill the time legnth of the PPro Clip object.

If you lengthen a layer in AE to be longer than the comp it’s in, if you don’t make the comp it’s in longer….you will not be able to trim the clip in PPro because the clip length is tied to the AE comp, not the layer within it.

Hope that helps some….

Thanks, Alex. This is a very useful perspective.
It’s so helpful to understand the principles behind a procedure.
Most training and documentation doesn’t offer this.
Cheers,
Robert
