Why do imported slideshows get choppy?

[pixelized007]

I have a slideshow, created in Windows Movie Maker, that I imported into Elements. When viewing the slideshow before import, the zoom and panning is smooth, but after it gets imported into Elements it becomes kinda choppy and not smooth-looking.

Why's that, and is there anything I can do about it?

How did you get the slideshow from Windows MovieMaker into Premiere Elements? What format is it in?

Windows MovieMaker was discontinued years ago. Windows 10 now includes the vastly superior Windows Video Editor. Have you checked it out?

As Steve asks, what format is it in?  Assuming it is in a default "MP4" format, it should work in recent versions of Premiere Elements.  There are a few settings that may need to be adjusted. 

What version of Premiere Elements do you have?  What are the project settings?  What are the Audio Hardware settings?  What is the Timeline Render Quality setting?  What is the Hardware Acceleration setting?
