Sounds good. MysteryX might also be interested in it for FrameRateConverter.
EDIT: Thanks Pinterf for the test build, it works much better! I presume you got the reply pm I wrote. After testing I was short on time and sent it in a hurry. Last edited by burfadel; 28th September 2017 at 12:06. |

New build: MvTools2 2.7.23 with depans
Download: https://github.com/pinterf/mvtools/releases/tag/2.7.23 Code:
- 2.7.23 (20171012) Fix: MScaleVect wrong rounding of scaled motion vectors with negative components. e.g. proper scaling (-1;-2) to (-2;-4) instead of (-1,-3) |

Does MVTools-pfmod in itself require libfftw3f-3.dll? If so, is it just for certain functions? The requirements section of the QTGMC wiki says it does, but I don't find that stated in any MVTools documentation.

I was wondering, is it possible to calculate the vectors on a 8-bit clip and then apply them on a 16-bit? King of like the ScaleVect function but that scales the bit depth. Analyzing vectors in 16-bit takes WAY longer.

On the other hand, I planned to revise 10-16 bit SAD functions, now they are simd intrinsics, which can be changed into faster hand written asm. And it can be even faster for 10 or 12 bits, taking into consideration of possible sum overflows. |

New release.
Download MvTools2 2.7.24 with depans A fix for a crash (see topic) in MFlowBlur. I think it was there from the beginnings. And there is a smart speedup upon MysteryX idea: generate vectors in 8 bits, then use MScaleVect to make it usable for an e.g. 16 bit MDegrain. On my pre-AVX2 PC it gave me more than 50% speedup for a basic MDegrain3 scenario. Try and give feedback. Code:
- 2.7.24 (20171205) Fix: MFlowBlur: possible access violation crash when nPel>1 New: MScaleVect parameter 'bits'. e.g. Analyze 8 bit clips, use their vectors for 16 bits Move project to VS2017 In brief: MScaleVect has a new parameter: 'bits'. When specified, the default value of the scale parameter is 1.0 instead of 2.0. So when you use 'bits' only, then the vectors won't be scaled by default by 2. Example: basic process, analyze in 16 bits Code:
a=..source bit=16 blksize = 16 blksizeV = 16 a8=a a=a.ConvertBits(bit) sup = a.MSuper(pel=2) #pel=2 fv1 = sup.MAnalyse(isb=false, delta=1, overlap=ov, blksize = blksize, blksizev = blksizev) bv1 = sup.MAnalyse(isb=true, delta=1, overlap=ov, blksize = blksize, blksizev = blksizev) fv2 = sup.MAnalyse(isb=false, delta=2, overlap=ov, blksize = blksize, blksizev = blksizev) bv2 = sup.MAnalyse(isb=true, delta=2, overlap=ov, blksize = blksize, blksizev = blksizev) fv3 = sup.MAnalyse(isb=false, delta=3, overlap=ov, blksize = blksize, blksizev = blksizev) bv3 = sup.MAnalyse(isb=true, delta=3, overlap=ov, blksize = blksize, blksizev = blksizev) a.MDegrain3(Sup, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=1000) Code:
a=..source ov=8 bit=16 blksize = 16 blksizeV = 16 a8=a a=a.ConvertBits(bit) sup = a.MSuper(pel=2) sup8 = a8.MSuper(pel=2) fv1 = sup8.MAnalyse(isb=false, delta=1, overlap=ov, blksize = blksize, blksizev = blksizev) bv1 = sup8.MAnalyse(isb=true, delta=1, overlap=ov, blksize = blksize, blksizev = blksizev) fv2 = sup8.MAnalyse(isb=false, delta=2, overlap=ov, blksize = blksize, blksizev = blksizev) bv2 = sup8.MAnalyse(isb=true, delta=2, overlap=ov, blksize = blksize, blksizev = blksizev) fv3 = sup8.MAnalyse(isb=false, delta=3, overlap=ov, blksize = blksize, blksizev = blksizev) bv3 = sup8.MAnalyse(isb=true, delta=3, overlap=ov, blksize = blksize, blksizev = blksizev) fv1 = fv1.MScalevect(bits=16) bv1 = bv1.MScalevect(bits=16) fv2 = fv2.MScalevect(bits=16) bv2 = bv2.MScalevect(bits=16) fv3 = fv3.MScalevect(bits=16) bv3 = bv3.MScalevect(bits=16) a.MDegrain3(Sup, bv1, fv1, bv2, fv2, bv3, fv3, thSAD=1000) |

Great job on the update!
Quality-wise, I'd be curious as to the difference between analyzing vectors in 8-bit or 16-bit, but since 16-bit processing was prohibitively slow and we were always better off using a slower preset in 8-bit, the real comparison should be between 8-bit processing and 8-bit analysis + 16-bit motions, both in terms of quality and performance.

Other people have reported it was perfectly stable with 100% CPU usage. Other great feature would be STAR search method. You can't use that library for that but you can copy/paste it from x265 library. |

Copy-paste??? Have you seen the source in mvtools and the one in x265? Spent quite a few hours on investigating the feature but couldn't get a grip on it. I found no common points between the two sources. Right now I don't feel like spending days or weeks on the problem.
