Yes, I did it, but I would like to know what the meaning of first and second
thesholds for vb/hb, and the threes of tn.
For examples, for tn help says:
tn tmpnoise (3 Thresholds) Temporal Noise Reducer
1. <= 2. <= 3. larger -> stronger filtering
How first threshold works? And the second and third?
What the difference from:
tn:16:32:1024
and
tn:800:900:1024
Same question on vb/hb thesholds.
