Smooth Slow Motion (once and for all!)
Can somebody please post a step by step guide to produce smooth slow motion.
The “ctrl drag” along with simply changing the velocity envelope will produce the same motion blurred slow-mo effect.
Im looking for the smooth transitions between frames. I’ve gone through most of the posts on here and have not yet found a clear, concise explanation.
Thanks,

If you would like to create a slow motion with the same frame-rate as your original footage (e.g. 29.97f/s), your software has to generate new frames, either by copying or interpolation. In both cases, you will loose quality (although interpolation should give better results than just copying).
The only way to create slow-motions without loss of quality is to generate your footage with a camera takes many more frames/second, so that the software doesn’t have to generate new frames.Theo

Here’s a trick from Douglas Spotted Eagle for you to try.
Duplicate the track once you’ve slowed it down.
Zoom in deep.
Turn off Quantize to Frames.
Nudge the top track to half a frame diff than the bottom frame.
Reduce opacity on top track to 50%. -
To explain slightly further, most footage shot with at 29.97 Frames per sec (usually said to be 30 FPS) or 24 FPS cannot be slowed down that much without exposing the slight jittery “slideshow” mode it goes into. Here’s a fun activity: If you’ve practiced slowing down various shots enough to get the feel for slow motion, try to see when major motion picture editors slow down a shot where it was filmed in 24 FPS. A skilled editing eye should be able to catch the slight jittery movement being forced on regular footage. Editors try to get by with this all the time, it’s always fun to catch them at it : )
A movie like 300, on the other hand, had parts specifically filmed with high FPS so that when the frames are played back slower, the motion is slow but the intra-frame movement is smooth. Unfortunately, most DvCamcorders or even prosumer camcorders do not offer increased or decreased FPS beyond basic 24 P, 30 P, or interlaced formats.
