Hi, I've noticed that when playing some videos with svp, the bottom and/or right edges wobble around noticeably. After trying to change a lot of the svp settings to stop this, I found that the motion vectors grid size affects it the most. Here's an encoded video of the svp output for demonstration (grid size 32 for maximum effect):

Different grid sizes made it better or worse, so I thought maybe it has something to do with the video dimensions not being divisible by the grid size. After adding lanczosresize(736, 416) to the avs script for this video (before the svp commands) to make both dimensions mod 32, the wobble is gone. Other resizes still show at least a small wobble, so I guess it is in fact caused by non-matching grids.

I hope this problem is fixable in the dlls, since you'd have to either crop pixels off the video or do matching resizes, which are both suboptimal solutions.
