If your source is standard definition it'd be faster to interpolate frames first, then upscale.

Absolutely, also interpolation will likely be better as will have shorter vectors when lower rez.
Also there is also a liimit to vector length and so upscaling beforehand would make it more likely that good vectors are sometimes not found.
EDIT: Actually, this is thread title "
How make automatical resize (downscaling) with avs?"
so unless OP changed his mind, might be better to interpolate after downscale.
