I guess the reason the deinterlacers don't rely on vectors is there may not be any for some blocks - I think the encoder can just use intra for any block as it wants.
Also it's not just vectors, it's vectors + residual and I guess the residual may affect things.
Yep - could be. Though every little helps? Having guide vectors would massively speed up block matching in a deinterlacer to find the right deinterlacing vector, as you could start with the guide vector and work around it? It's a bit like Phase Correlation being used upstream of Block Matching in Alchemist or Quasar?
