I tested the convolution script posted by *.mp4 guy but it's very slow and it's very blurry. The vertical resolution is bad and the conversion speed is like 0.5 fps on a fast machine.
I tested the new corrected shift/interleave script:
Code:
Global NewHeight = 480
Global NewWidth = 720
DirectShowSource("hd.m2ts", audio=false)
# Pick one manually, DirectShow has no idea
AssumeTFF()
#AssumeBFF()
SeparateFields()
Shift = (GetParity() ? -0.25 : 0.25) * (Height()/Float(NewHeight/2)-1.0)
E = SelectEven() . Spline36Resize(NewWidth, NewHeight/2, 0, Shift)
O = SelectOdd() . Spline36Resize(NewWidth, NewHeight/2, 0, -Shift)
Echr = SelectEven() . Spline36Resize(NewWidth, NewHeight/2, 0, 2*Shift)
Ochr = SelectOdd() . Spline36Resize(NewWidth, NewHeight/2, 0, -2*shift)
Interleave(E, O)
IsYV12() ? MergeChroma(Interleave(Echr, Ochr)) : Last
Weave()
Compared with the initial version (that didn't process chroma separately), this one looks very similar. I didn't do an A/B comparison, but viewing them successively I can't tell any difference.
The corrected version is a bit slower (10.3 fps vs 12.7 fps) but that's OK. This new script supposedly deals with chroma correctly, so I think I'll just use it.
Are we out of ideas yet?
