Saltysally1if you record at a higher frame rate and turn off multisampling your videos will look a lot crisper, it's the difference between great and average.
host_framerate <x> in console before you start recording to get the FPS required for optimal slow motion
Right click on your video and go to the bottom under properties and click off under multisampling.
EDIT: i'm assuming you use sony vegas.
I used to do 960, but 480 is good enough. I simply don't have enough space to do every smooth at 960. My original avi file looks a lot better than on youtube.. And you mean resample or ghosting? I did that for all clips in this video.
