What is the best way to get a smooth playback when editing?
Vegas Pro relies completely on your computers processing power, so the biggest thing you can do to improve your frame rate during preview is to use the most powerful machine you can. That said, many variables go into determining how hard your computer has to work in order to keep up with the frame rate youve set your project too. For instance, some video file formats perform more efficiently as source footage than others. Its much easier for the software to process DV footage than AVCHD footage as just one example. The complexity of the video plays a big factor as well. For example, a native clip will play back faster than the same clip loaded with video effects and transitions or composited with another track. You might also see improved preview playback frame rate if you match your project video properties to the source footage in your timeline. Beyond your computers CPU speed, other hardware issues can have an effect on preview playback rate too. For instance, the speed of the drive
