First, what it is: Supersampling as the name suggests means a range of frames get 'super sampled' or adjusted bringing out detail and/or removing some types of artifacts. This is accomplished with a envelope. A special one that needs to be actived differently than most.
Like this: From View, check Video Bus track. The track ALWAYS is at the bottom of your other tracks and you may need to grab onto one of those infamous gray thin lines above the track to resize it to make it fully visible. Once you see it right click, Insert/Remove Envelope and select Supersample. A typical envelope line (brown in color) gets added and you can add points anywhere along the 'envelope' as needed.
For supersample to do anything beyond vastly slowing down the render process two things, sometimes three need to happen.
1. first selectively apply the envelope to only the sections that need it by setting points where the supersampling should take place be sure to drop the envelope to zero elsewhere.
2. Be SURE the source file has BOTH a different frame size and frame rate than your project. If only one or the other, nothing happens.
3. Apply some filter like blur or sharpen.
So just what happens with supersampling? Vegas adds intermediate frames and renders them based on the settings of the supersample envelope. So if you select 2, Vegas renders twices as many frames within the envelope. Pick 4, it does 4 times as many and so on. All that recaculating takes time.
This 'can' improve poorer quality video. Sometimes a lot. Most times not that much. Depends on the source file. Even video already generated in Vegas... can SOMETIMES be improved if you first render the 'bad' section at a frame size and rate othen than your final intended project parameters then go forward with the supersampling in the final render. I've tried on a few projects and was happy enough with the result to add it to my bag of tricks.
Along the same lines rendering out a AVI file in VirtualDub at half your project frame size (don't mess with fame rate here) seems, sometimes, to improve the result of some filters since Vegas is forced to recaculate each frame to bring it up to your project parameters.
