So in doing mainly greenscreen with these which is the better the new hf10 recording at 1920x1080 or the older hg10 recording 1920but saving 1440x1080 to file?

Would that make a difference for greenscreen?

and for mainly greenscreen would 60i be better than 24P? and if using the hf would 30P be better than 60i and 24P?

I am also considering the sony SR11 over the HF10 if it seems the 60i would be better or as good as the 24P for this, any reason that I should not do that?
