![]() I was able to get an 8x speed up (I have 8 cores) when I switched to the multi-core version of AVISynth. By contrast, if you use the hacked version of AVISynth which takes advantage of multi-core, denoising can be extremely fast. Maybe they have updated it to solve that problem. ![]() I do a LOT of noise reduction work and still find that the fft3Dfilter and the Degrain filter (both AVISynth plugins) leave fewer artifacts, especially when combined with motion compensation where you temporarily remove all motion between frames by moving all things that have moved from the previous and succeeding frames back to where they "were" in the reference frame, and then do the de-noising.Īlso, Neat is painfully slow, even on SD. It is probably the best spatial noise reducer out there, but the simple-minded temporal noise reduction is not very effective. I have tried Neat with both SD and HD on a number of occasions.
