Took 4 hours to render the still. Looks good.
Brought it into Motion instead of AE or Shake as Motion has some complete UI animated graphics that I can just add without too much effort.
Added some live elements from Detonator HD, some Bad TV filters to grain it all up and look like crap space footage!
Did a test export and is looking okay. I think I will add the 'Rovers' shadow and possibly a hint of a solar panel.
Need to go back to the film to see the timings and tidy the edit up to match. I need to show the Mars footage on the Mac screen I made up for the Census clicking page with the two actors faces 'screened' onto it like a reflection.
Then it's done!!
