Faked in-camera slow frame rate

Hi all,

I’m trying to recreate the look of shooting 6fps in-camera with each frame printed four times (to get back up to 24fps). It’s used quite heavily by Peter Jackson in LoTR. The key characteristic of doing it in camera are high motion blur in each frame (since it was actually a 1/12 sec exposure).

I have 24fps footage. Applying the “Posterize Time” effect set to 6fps gets the frame rate down; turning on frame blending gives – well – frame blended 6fps material. Finally adding a Timewarp filter with speed set to 100% but motion blur turned on starts to smooth the blended frames.

It’s still not quite right, though. Ideally, I’d be doing a pure motion interpolation from the 24fps down to 6fps – with all those extra frames to hint it, the algorithm should be able to create wonderfully realistic motion blur.

Any thoughts?

Ben
