I figured out how to speed up a clip while keeping the same fps: A combination of "change frame rate" and "convert to fps" that offset each other results in a clip that gives you any amount of decimation you want. It worked perfectly: I was able to convert a 300 second 30fps clip into a 30 second 30 fps clip.
However, it looks like it was shot with an ultra-fast shutter. An arm "jumps" from frame to frame. What I would like to do is use the discarded frames to try to create a more realistic motion-blur.
Ideally, it would be something like AfterEffects "Time Remap" with the "Combine Frames" option (I don't own AfterEffects so I'm guessing on the names)
Output Frame 1 is a merged equal-weight combination of input frames 1-10, output frame 2 is a combination of frames 11-20, frame 3 is 21-30, etc...
Any ideas?

This requires motion compensation in order to do adequately; pure blending actually looks worse than just replicating the frames. Currently, VirtualDub does not have such a filter, as it's pretty complex. |

Duplicating frames? It sounds like you mean stretching it out. I'm going for speeding it up and instead of dropping frames, blending them instead. |
