There are a few ways to get your vids correctly.
Don't use a camera. Video capture devices that take an input signal only.
Don't use anything but 1x speed
If you have a vid capture device that captures in 60fps, then you're good.
If you have a vid capture device that captures in 29.97fps Interlaced, then you have to capture it at that rate, and then using software such as VirtualDub, double the framerate by splitting up the interlaced frames into their own frames to get the full frame rate. (i.e. VDub's "Bob Doubler" filter)
You will also need software that allows you to progress the video one frame at a time and go backwards. I HIGHLY recommend VirtualDub, and it can be found here: http://virtualdub.sourceforge.net/
Any questions about capturing frame data should be directed to this thread.
