hi , i have a slow motion shot in a film...of a vampire being decapitated actually !
there is a lot going on in the scene, blood splatting, a metal disc flying through the air, his head spinning away into the distance.
essentially the shot looks way better in slow motion because its a hard thing to animate, and the slow motion helps to sell the shot a bit better.
however,but i made one terrible beginner mistake with this scene. i shot it at 23fps, so i have one issue that by putting it on slow motion, it looks very choppy and might even give a viewer the impression that the video is not playing back properly.
is there any way for me to smooth it out by ,perhaps morphing the frames to "fill in the blanks" so to speak from within after effects? and if a third party plugin is needed, what would be the best and most economic option?
The best plugin option is NOT cheap: it's Twixtor by revision efx.
If you don't have the budget for the plugin, you can use AE's built-in interpolation methods. Look in the AE help for info on Frame Blending and the various ways to do it.
In this FAQ I give an overview over the options you have:
If you choose "pixel motion" as fame blending option, AE is morphing the frames as you suggested, but this morphing can easily create artifacts depending on your shot.
