Rendering performacne of Vegas MovieStudio 14
It is normal, that different software outputs different results in different time ranges. Maybe the effect you use in AP Elements is much simpler than the one in MovieStudio. Or Movie Studio uses more ressources to run. Or the settings were not exactly equal.

In general you improve rendering perfomance with the following steps:


Close internet connection
Remove all media from the computer that is not needed for the rendering
Deactivate temporarily all programs in background (e.g. anti virus) that are not needed ( ATTENTION: Don't take any risks. "Maybe" always means "Leave it!")
Only open data that is directly related to the media you render. ( No other projects in background )
Leave the system alone during work
For Windows: Defrag Harddisk before rendering
