EZdenoise - Page 4

Added EZdenoise v4
Hardcoded "Falloff" parameter.
Added "out16" parameter (which only supports 8bit sources).
Using out16=true is 15% faster than using ConvertBits(16), because MAnalyse now respects the bit depth of the input.
Previous versions had MAnalyse run at 16bit (if ConvertBits(16) was used) which didn't improve image quality and only wasted performance.

For 8bit inputs, I highly recommend you to use out16=true. Use something like this for maximum quality:

Code:

LWLibavVideoSource("C:\Users\Admin\Input.mkv")
EZdenoise(Chroma=true, out16=true)
ConvertBits(10, dither=1)
Prefetch(12, 48)

For better quality/performance tuning and if using 'post-2.7.45' version of mvtools with MdegrainN and interpolated overlap modes you can add some set of 'overlap-mode' param. Starting from that release https://forum.doom9.org/showthread.p...79#post1972579

4 interpolated overlap modes available in MDegrainN and standard overlap in MAnalyse.

So some possible overlap-mode settings in (expected) increasing performance order:

1. MAnalyse overlap = blocksize/2, MDegrainN IntOvlp=0 (full 4x blocks number MAnalyse search and degrain 'real searched' overlap, highest quality mode, slowest)
2. MAnalyse overlap = blocksize/4, MDegrainN IntOvlp=0 (lower blocks number MAnalyse search and degrain 'real searched' overlap, a bit faster)
3. MAnalyse overlap = 0, MDegrainN IntOvlp=1 (1x search blocks number, 4x interpolated blocks number overlapped degrain with SAD re-check)
4. MAnalyse overlap = 0, MDegrainN IntOvlp=2 (1x search blocks number, 4x interpolated blocks number overlapped degrain without SAD re-check)
5. MAnalyse overlap = 0, MDegrainN IntOvlp=3 (1x search blocks number, 2x interpolated blocks number overlapped degrain with SAD re-check)
6. MAnalyse overlap = 0, MDegrainN IntOvlp=4 (1x search blocks number, 2x interpolated blocks number overlapped degrain without SAD re-check)
7. MAnalyse overlap = 0, MDegrainN IntOvlp=0 (no overlap, lowest quality, fastest)

I typically use mode 5 for most encodings.
