This should be a good fast solution to Zep's problem and I expect it will make Decimate() obsolete. I've already begun coding.
YEAH!!!!!

I need this BIG time cause I now have tried multidecimate
(which does fine but audio sync is hosed to a point I can't
fix unless i spend hours sliding around audio chunks)

smartdecimate same problem as normal decimate, i.e. the
rapid pattern changes confuse it and it too drops singletons
as well as AA pairs. (which shocks me that it would drop
2 good frames and cause a jump in motion. however the read me
did say if you do not have pattern it would fail so...)


This truly is a case where I can't help the function
by walking it and getting a pattern because there is none.
We truly have to have a super smart decimat to the point
where Decimate(23.976) is all that is needed.


DG I am very impressed you can pull that off with 1 pass.
i was almost certain it would take 2 passes.

this is great news!


Thanks
