200 fps to 25 and 30fps

Basically like it says, I have footage that is 200 fps, when I convert it to 25fps it is really jumpy as you would expect. Any one got any ideas to make it look more smooth?

.. I'd need to see the Original but, this should work fairly well without too much motion loss. The trick "here" is to let the Encoder decide which frames should be merged - this can be altered by the Encoding Speed ( fps. )
.. Mpeg loves to merge things together and display a blend of multi-frames as one frame; so, in theory, it can be done. Mpeg2 would be my choice. How it should work is quite simple: Mpeg has an Internal and External speed when encoding. Interally, it can make up to three frames per second seeming to being changed within a single frame being made.
.. The older versions of TMPEncoder should be able to handle it and I know that any true Ulead Encoder can handle +200 f/s. Simply set the Rate option for "internal 200 f/s" and set the encode for ±47 f/s .. From that point, simply encode it once more with an Mpeg Encoder on Internal f/s to the desired f/s and TADA

.. yeah, its quite old-school to rely on the flaw of the mpg designers group however; those designers were trying to make Motion Pictures at 60 f/p work on 14 to 18 frame Per Second 386SX33 16 bit processors, Video Cards with very little memory and no math co-processors - so I think this flaw in their design can be of a benefit to your situation. When frame accuracy is not important, mpg is the way to go.
.. if you decide to make it an AVI from those Mpeg2 down-muxxings, use Xvid for your final encode - its an MPG encodable Codec.

.. P.S. if there is a better way to do this, I'd love to see it work right.

Thanks for your help will start encoding soon.
