Deoldify Vapoursynth filter

[Dan64]

I tested vsPipe with "y4m"

Now the speed decrease to 6.24 fps.
So to speed-up the encoding is not the pipe but the "raw" format.
An increase of speed of 1.9x is worth your attention.

You should consider to abandon the "y4m" format for vsPipe and switch to "raw" format, please check if you obtain the same increase in speed.

Thanks,
