Can a video morph in PowerPoint? The answer is yes (but not completely).
The great thing is – a video placeholder works with Morph. Here is my two slide sample, the video on the second slide has been resized to full screen.
In the demo video below, the sample video growing to full slide size with a Morph transition works perfectly. However, due to a limitation of how PowerPoint plays videos, a video cannot play across slides. In this sample, the visual works nicely with the 2nd slide set with a shorter slide transition duration (morph) and a Play-with-Previous to have the video start playing instantly after the morph finishes. But a video with audio or content that would look awkward with a pause will not work as well (visually).
