I have a problem with my compositing
What i am trying to do is place an actor in a scene at night where as he couldnt act the night i was filming. i was wondering if i could get some tips on how to successfully composite him in so the colour of him and the scene are equal and he isnt pixelated which is what is basically happening
if you could help that would be much appreciated

Could you upload some example images showing the greenscreened actor and the shot you're compositing him into? Nighttime can look completely different depending on your style, so we need to see some pics, really.
As for the pixellation...not sure what's going on there. Are you scaling him up?

Thanks. Whereabouts in the shot is the guy meant to be composited?
A few things spring to mind immediately:
- The greenscreen shot appears to be massively backlit by presumably the sun. This isn't a great idea, as the glare could cause issues.
- You've filmed the greenscreen shot from a very long way away. Generally it's best to film so that the greenscreen element fills the frame, as this then gives you more flexibility. Don't forget you can always shrink an element if necessary, but you can't make it bigger without making it pixelly.
