:ph34r: 2 Months ago, somebody brought me some material that was supposed to be shot in 24p, but was by error processed at 30p.
For this case, I have used Media Composer Adrenaline using the fluidmotion effect. This is complicated (vector base). And this was a really...really long process (rotoscopy), but let me tell that the final look was gorgeous. Everything, the picture, the movements became very very smooth...much like film.
So, :ph34r: if you have the chance...i would really recommend this technique. But, like i've said...this is a very long and complicated process.
