crippled frames at the Beginning of temporal filtering
Posted: Thu Apr 19, 2007 9:49 am
Hi,
I'm testing the demo-version of the NV Premiere plugin and was very impressed of the quality of the temporal filtering.
As I use the plugin on small clips in my video-projects I noticed a strange behavior of the temporal filtering: each clip starts with one up to three crippled frames before the filter works as it should. These crippled frames vanish when I disable the temporal filtering (radius 0) and they grow up when using higher radius values. If I decrease treshold values the effect is nearly away, but surely the temporal filtering effect is nearly away, too.
I made a test-clip (PAL DV AVI) with temporal filter radius 3, threshold 200, adaptive filtration 0 to show what I mean.

Is this a normal behavior of the filter?
