In many cases it can also adversely affect the quality. This increases the load on VEGAS and reduces your chance of smooth playback. If your project frame rate does not match the frame rate of the media on your timeline, VEGAS Pro will resample it (combine frames) unless you disable resampling. To manually adjust the project properties, click the button at the top right of the ' Project Properties' window and choose a typical media file that you wish to match. If you want to change this setting later, it's in ' Options' > ' Preferences' > ' General': I also like to check the box so that I am not asked again. By default, when you first drop media on the timeline you will get a prompt like this: Make sure your Project Properties match the your media properties.
Try this first to clear caches etc., especially if you don't routinely shut down your PC.
There are a number of things you can try to improve the smoothness of your preview. Your preview playback frame rate is displayed below the preview and in some cases it may be less than your project frame rate, causing the picture to stutter or lag.
