A theoretical example
Original top fields: A B C D
Encoded as: A (blend AB) (blend BC) C D
Original bottom fields: a b c d
Encoded as: a b (blend bc) (blend cd) d
In the example you can disregard the nonlinear blending and just consider the constand blend case.
Will it be able to produce a goodlooking top field B and bottom field c?
If yes on that, can it in theory handle nonlinearly blended frames as well to recreate B and c?
If not... is there any 3D interpolating scheme (or something) that can recreate B and c using Aa b C and Dd?
edit:
I can't test the filters until beginning of June for various reasons.
