Noisy and aliased video

[vooyeq]

Hi there,

Trying to get rid of noise and aliasing. What can I possibly make of these clips ?

smdegrain seems to work quite well with the noise, but I'm still left with terrible aliasing [AA script blurs image too much].

Quality before speed.

Videos, quite obvious, nevertheless:
clip_x.ts - source
clip_x_smd - source + smdegrain
clip_x_smd_aa - source + smdegrain + aa

aaa = o3.eedi2(maxd=8).bicubicresize(ox,oy,0,0,0,0.5).turnleft().eedi2(maxd=8).turnright().bicubicresize(ox,oy,0,0,-0.5,0)

Thanks.
