Shift a plane

[Cary Knoop]

How do I shift a plane both horizontally and vertically in Vapoursynth?

[poisondeathray]

Were you referring to "Y, U, V " planes or similar ?

One way is to Crop, then AddBorders .


Actually, I think source crops are built into the internal Resize. Yes they are


src_left, src_top, src_width, src_height:

Used to select the source region of the input to use. Can also be used to shift the image. Defaults to the whole image.

Got it, thanks!

I suppose sub-pixel shifts are not supported in Vapoursynth?
I could always do a point resize up, then shift and then point resize back down.

They are in avisynth, I would imaging they are in the Resize too

Yes, it looks like the function is taking floats.

Maybe see avisynth thread here (Move/shift frames without crop ):- http://forum.doom9.org/showthread.php?p=1718440&highlight=ShiftClip#post1718440

fmtc.resample has it, you can assign floating point values to sx and sy
