I'm editing using Sony Vegas Pro 9. I also have After Effects CS4 for motion graphics, titles, etc.
After having some problems with my slow motion looking choppy with 30fps footage (since it was just copying the same frame to create the slow motion), I was told the best solution was just to shoot at a higher frame rate.
So, now I'm shooting at 60fps (progressive). However, what's the proper method for actually creating slow motion from this? I've seen in some FCP forums some people recommending that you actually change the FPS of the clip to create slow motion. Is this the proper approach, or should I be using Vegas Pro's built-in slow motion utilities like ctrl-dragging the length of the clip, or using velocity envelopes?
