Which video scaling filter to use?

[quu]

In the command line help there is

Code: Select all

--swscale-mode={0 (Fast bilinear), 1 (Bilinear), 2 (Bicubic (good quality)), 3 (Experimental), 4 (Nearest neighbour (bad quality)), 5 (Area), 6 (Luma bicubic / chroma bilinear), 7 (Gauss), 8 (SincR), 9 (Lanczos), 10 (Bicubic spline)} Scaling mode Scaling mode to use.

first off... it does not say which is the default

I already read the Bicubic vs Lanczos thread, but there does not seam to be a "tap" option options in command line switch. Plus the command line switch appears to have allot more resizing options.

for primarily animation sources, which would be the better resizing algorithm? (I am guessing the "best" is subject to allot of variables)

I tried checking the wiki for a writeup on what the different ones do and why.
