I’ve been using Prezi Classic since 2012 and always hate the jerky motion. BTW - I tried Next and was disappointed with it’s creative limits and predictable template.
Fixes…
- Always use the desktop version
- ensure all images are no larger than 1200pixels wide and make them all png’s if possible. Background images can be larger.
- Prezi was still jerky until I quit the program and restarted - prezi is smooth as glass now
