Bye bye blurred frames

[martin53]

I tried to automate the task of replacing bad frames in a clip by other frames. The result is the attached filter function FSubstitute().

Edit: you can find an abstract some posts below.

The filter uses MVTools2's MCompensate and MFlowInter functions to reconstruct frames, as well as Freezeframe.

Target are
- blurred frames because of rapid camera movement
- super8 digitized clips with some bad frames from broken machinery or cutting
- frames with compression artefacts or blur from compression bitrate shortage

Usage is documented in the script header.

For the list of plugins and their versions see bottom of script.

The filter is slow when effective. It is possible to bypass good frames with appropriate parameter settings and thus get acceptable overall speed. I get about 3FPS with thoroughly processed 640x480 footage on a Core i5/750.

When you give it a try, watch the memory usage. I process clips in slices of max. 10000 frames.
Sorry I failed writing in a tidy style. It is commented extensively.
It it is surely not bug free. Comments are appreciated! But please have patience.
