In any case conversion between YV12 and NV12 color formats is lossless so you don't need to worry about it.
They different only in order of color planes in memory. Why ffdshow outputs in NV12 by default? Probably because of

NV12 is the preferred 4:2:0 pixel format for DirectX VA.


> but why the conversion between 1280*720 to 2048*720 occurs in ffdshow

for example, if you have 2048-width screen and "outer lighting" in SVP is on

Read this first

The last SVP version supporting 10.10 is 4.2.146!

It's impossible now to install Vapoursynth libs (and mpv with Vapoursynth support obviously) via Homebrew due to missing zimg dependency - Homebrew says

zimg: macOS El Capitan or newer is required.

What we can do? We can build zimg, Vapoursynth and mpv manually and place them into Homebrew's "cellar".

So, considering a clean OS X install, the following should work:

1. Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Install all the mpv dependecies:

brew install libass tesseract python3 mpv

this can take a while, especially on 10.9
3. Remove installed mpv cause we gonna replace it with our own build:

brew unlink mpv
rm -fR /usr/local/Cellar/mpv

4. Unpack .tgz with pre-built zimg, vapoursynth and mpv into /usr/local/Cellar
5. Link our binaries into /usr/local:

brew link --overwrite zimg vapoursynth mpv

6. Restart SVP

it's a warning message about that
probably a little bit outdated now hmm

why?
see All settings -> frc.prefetch section.

you can try 8K videos from Youtube big_smile

nope

10-bit is only for mpv and VLC

neither ffdshow nor PotPlayer doesn't support 10-bit Avisynth processing


> Do I set the output of ffdshow raw video filter to 10- or 8-bit?

8-bit

as I said before, may be (!) the major difference comes from

prefiltered = RemoveGrain(C, 22)

nothing can stop you from pre-process video before svpflow

=======

prefiltered = RemoveGrain(input, 22)
super = SVSuper(prefilter,"{gpu:1}")
vectors = SVAnalyse(super, "{refine:[{thsad:100}]}", src=prefilter)
smooth = SVSmoothFps(input, super, vectors, "{rate:{num:2,den:1}, algo:21, mask:{area:50}}", mt=threads)

=======

 BlkSize    = Default(BlkSize, C.Width>1200||C.Height>900 ? 32 : C.Width>720||C.Height>480 ? 16 : 8)

you know you'll get significantly different results for the same video scaled to different sizes, right?

> doesn't SVP process and output at 4:4:4?

nope

you can get 4:4:4 from 4K YV12 only if you'll scale down to 1080p after SVP and the scaler is smart enough to not scale chroma planes (i.e. - madVR, not sure about EVR)

Use 64-bit MPC-HC.
Otherwise you may need to reduce number of processing threads in SVP down to 9 or even more (I haven't tried it with 10-bit 4K in 32-bit MPC-HC)

> Is this the same method you use?

this's the idea
mask resulting frame with two source frames in "bad" areas, where "bad area" means "area with high SAD value of the motion vectors"

"external" implementation requires 10 lines of avisynth code and is slow as hell
"internal" implementation requires just another multiply-add operation for each frame pixel

Nothing can stop anyone to take .dll/.so/.dylib from the SVP installation wink

But I agree that it should be updated. We'll do it soon enough...
However there's nothing useful in the Avisynth part since rev.128
