Same, winner is Method1-Final2.Ĭomparing the 3 winners. Using finalm=2 (BM3D), between method 0 and 1. Using finalm=1 (KNLMeansCL), between method 0 and 2. but BM3D has a tiny bit more grains and/or details. KNLMeansCL and BM3D are very very similar, hard to notice any difference at all. I will do the same comparison on other types of content.Ĭomparing method 0, 1, 2. I'd say the winner is Method1-Final2īetween the 3 winners, Method1-Final2 gives sharper details, but Method0-Final1 removes more grain. Using finalm=2 (BM3D), between method 0 and 1, KNLMeans keeps sharp details, I like it.
I'd say the winner is Method0-Final1, the seat looks a little bit better and it removes more grain Using finalm=1 (KNLMeans), between method 0 and 2, it's a very close call.
Overall, I'd say the winner is KNLMeansCL. Method 2 (BM3D): sigma=9, radius=1, processing in YUV444PSĬomparing method 0, 1, 2. Method 1 (KNLMeansCL): d=3, a=2, h=1.4, processing Y and UV separately Method 0 (MVTools2, VapourSynth version): thSAD=400 I find that all 3 methods benefit from renoising and sharpening from xClean. One: every once in a while, you wont be able to find a uniform area in your image.XClean now fully support MVTools (0), KNLMeansCL (1) and BM3D (2) methods with renoising and sharpening, and can then apply KNLMeans (1) or BM3D (2) with the first method as ref using finalm. This is really useful because it tends to keep your image looking nice and natural.
The plugin then takes that information and decides exactly what the noise in your image looks like, and then denoises it accordingly. To create a Noise Profile, you have to select a decently sized area of your image that is uniform.įor example, the gray street area in the image above would be a usable area. Its always been very powerful, and over the years, it has only gotten better.
There is also an upgrade path (99) if you own previous versions of the software. However, this usually means there were some pretty serious noise problems in your footage to begin with. The biggest thing this new version has going for it is that it renders on the GPU, which means that the results come almost in real-time.įor this new version, the developers completely re-wrote the entire plugin with speed in mind.įor most scenarios, the default settings on the plugin will get you where you need to go.Įvery once in a while, youll get some images that look a bit blotchy and unnatural. You just may have to wait a while, especially if you have multiple shots to process. The plugin defaults to showing you a preview region, so to view the final output, you have to change the Viewing Mode to Final Output.įor some of the more grainy shots (like the one above), to get an even passable result, you need to turn up the Noise Reduction level to at least 2 or 3 and raise the Passes to around 3 or 4.Īt times, with some of the most grainy images, it would take almost thirty seconds to view one frame of the final output. The biggest thing that holds this effect back is that its extremely slow. If youre in Premiere, youre going to have to send your footage over to After Effects by right-clicking and selecting Replace with After Effects Composition and then go back and forth.
A major limitation of using this effect for noise removal is that its only available in After Effects.
