How does Motion Path easing work?
Aug 09, 2018
I'm hoping someone can help me figure out how the logic behind the motion path duration, easing direction and speed settings work together.
I have 4 identical images set up on a slide. The images are aligned left and each has a straight line motion path of the same length.
The duration is the same for each (5.25 s)
When I apply Ease In to the images and assign a different speed to each one (slow, medium, fast, very fast) this is what I see:
- The slow image starts first.
- The very fast image starts last.
- All images finish at the same time.
In this case, I expected to see the opposite result in that the image with the slow speed would ease in slowly and the one set to very fast would ease in the fastest. I also expected that all 4 would finish in 5.25 seconds which is the duration set for each motion path.
When I apply Ease In/Out this is what I see:
- Slow starts first but finishes last.
- Very fast starts last but finishes first.
In this case, I expected that the slowest image would ease in slowly and ease out slowly and very fast would ease in quickly and ease out quickly. I also expected that all 4 would finish in 5.25 seconds which clearly is not the case because they all finished at slightly different times.
When I apply Ease Out this is what I see:
Slow starts last and finishes last.
Very fast starts first and finishes first.
In this case, I expected each image to start and finish at the same time, but the ease out would be faster or slower depending on the speed setting.
