Time Strech effect working in opposite way?

[Francisco_VideoEditor]

I looked up how to slow down footage in AE and found the 'Time Strech' Tool. The tutorials I found said to bring the percentage down to anything below 100%. In my project however, the footage needed to be above 100% in order to slow down my footage? Has it always been this way? Or did it change or do I have something wrong with my set up?

Yes it seems backwards but this is how it works.

In After Effects, changing the percentage is changing the time of the source footage.

In Premiere Pro, changing the percentage is changing the speed of the source clip.

And yes, it's always been this way.

If we prefer one over the other, we can copy and paste between After Effects Timelines and Premiere Pro Timelines.  So, to adjust source footage based on speed, copy and paste it from an After Effects Timeline to a Premiere Pro Timeline, make the speed adjustments, and then copy and paste the clip back.  For best results, the Timelines should be at the same frame size and frame rate and the After Effects Composition duration should match or exceed the In to Out Durationb f the Premiere Pro Sequence.
