Can somone show/tell me the best way to shoot and edit a super slow motion shot of a person running. I've serached high and low, but still can't find the best solution. I'll be shooting with a DVX-100b and editing with Premiere Pro 2.0 and AE 6.0.
 
Thanks, that tutorial was definetly helpful, though I'm trying to make something MUCH slower. More like a 15%-20% of the original speed. Any idea how to do that?
 
It's very difficult. The motion information just isn't there. 50% is the slowest that you can possibly get and still get decent result. You can try investing in Twixtor but that plug-in has a huge learning curve and I've never been able to get satisfactory results with it.
 
You'll probably have to look at somwething like the RevisionFX Twixtor plug-in for AE 6.

Otherwise upgrade to AE 7, it can interpolate frames.

How and what does interpolating frames do to the video exactly?

To get slow motion, you need a higher number of frame than the number of frame per second your timeline is set at. For example, if you have a clip shot at 60 frames per second running in a 30 fps timeline then the footage will run 50% slower because there are twice as many frames.

Now, let's say you shoot 30p and you want to slow it down 50%. The software will try to "make up" 30 extra frames based on the existing 30 frames to give you 60 fps video, this is "interpolating". The problem is, with progressive footage like 24p or 30p, you have a limited amount of motion information for the computer to "guess" what the next frame should look like, so it will basically duplicate frames to give you slow motion footage, which will look stuttery and low quality.

Softwares like Twixtor use more sophisticated algorithms that can extract more information from your existing frames, or smartly fills in the missing information to give you smoother slow mo. I'm not trashing Twixtor but before you consider investing in it you should be aware that it's not a plug-and play software. There is a huge learning curve associated with it and you'll most likely have to experiment many times before you can come up with satisfactory results. RevisionFX offers very little coaching on the plug-in and the manual is very dense and confusing; if you're expecting quick and easy results you'll most likely be frustrated. This is why the variable frame rate feature on the HVX is one of its chief selling point; slow motion in post is difficult to achieve.
