When I use TemporalDegrain() I sometimes get deformed motion. It almost looks like a 3D rotation effect - some foreground objects move faster than some background objects.
For example, using
a = last
a.TemporalDegrain()
on http://www.mediafire.com/file/0lym5r657vplaa7/Wide-angle_lens_blurring_sample.wmv, there's deformed motion between frames 22 and 23. In other places too, but that's a good example.
Reducing degrain or SAD1/2 (by a lot) helps a little, but in either case denoising effectiveness is reduced obviously. The only thing that prevents almost all deformation is setting HQ=0, but that also reduces denoising.
Is TemporalDegrain() suitable for clips of widely varying sharpness like this one? If so, what are the recommended settings to use with HQ>0 but without deformation?
Is there another MC temporal denoiser that's more suited to this kind of footage perhaps?
Many thanks,
Francois
