VerticalCleaner: Probably belongs in the 'lightweight denoiser' category using it's default settings.ĭenoisers which don't denoise the first frame would be an issue for me.

VagueDenoiser: Probably belongs in the 'lightweight denoiser' category using it's default settings. TTempSmooth: Default settings don't seem to do a great deal of noise removal. Considering how effective it is the amount of blurring is acceptable, although it probably blurs a little too much for my taste. TemporalDegrain script: Removes a large amount of grain/noise using default settings. RemoveGrain: Doesn't seem to do a great deal of noise removal using default settings.

It removed a great deal of noise and while it did blur a little, for some reason I didn't find it too objectionable.įft3dfilter: Caused as much blurring as a couple of other filters without removing as much noise.įluxSmooth: Seems pretty similar to degrainmedian. Feel free to tell me if you disagree.ĭegrainmedian: Seems like a decent compromise between noise removal and blurring, as long as you're prepared to overlook the first frame which it appears not to denoise.ĭfttest: Removed a fair percentage of noise while at the same time blurring too much for my taste.įastDegrain script: Subjectively, I liked the result. Being fairly lazy myself though, I'd prefer to use a 'one size fits all' denoiser which I know will do a pretty good job without my needing to spend time making adjustments every time I use it. If anyone would care to try denoising it with clever filter parameters or a different filter please feel free. I've included the original video with the samples. The two script based denoisers I tested did a pretty good job removing a large amount of noise without too much blurring, but for me, QTGMC's output is still more pleasant to look at. In fact QTGMC can have a slight sharpening effect instead. It didn't necessarily remove the most noise, but it does 'stabilise' what it doesn't remove so it no longer seems as 'noisy' and therefore it doesn't blur the picture as some noise filters do. In my opinion, QTGMC does a better job (or at least more pleasing to my eye) than the denoisers even though it's not officially a noise removal filter as such. I was going to post screenshots of each test encode but they really don't tell the full story so I uploaded small samples instead. The main purpose for doing the test encodes was to compare other denoise filters to the filter I've been using for denoising despite the fact it's not officially a denoiser (QTGMC in progressive mode). I have no doubt some of the denoisers could do a better job if I fiddled with their settings but I'm far from being an expert there so I just used the defaults. This isn't anywhere near being a definitive comparison and it was only done use the default settings for each denoiser.
