I was using an RGB image sequence source - not a quicktime source,
so that might already be
assumed to be 709...
In the end I found that the default scaler was causing the slight green tint.
If you add this flag:
this fixed the green tint I was experiencing with the default down scaling.
Note that lanczos alone will go green without the +accurate_rnd option.
