You mean in just learning them both? Lynda.com just can’t be beat short of having an expert sit next to you.
After Effects will take much more to use depending on your current knowledge of how video is different than print…resolution, codecs, formats etc.
InDesign is another layout tool.. even with the new interactive capabilities, which shouldn’t be there in my opinion but that’s a different story, it’s about the design of a static moment in time.
After Effects looks at the beginning, middle and end and everything inbetween so obviously the ramp-up time for AE is going to be longer.
Plus, the hardware used (RAM, storage, processor speed) are all much more important and effect directly your work experience in AE.
But, both are great to learn.
