I have rendered these stills out in High Res HD 1080 and have turnt out really well.
I decided to create a low resolution texture, rendering in 640x480 and it has already surprised me and looks really good.
To render this I first set up a sun and sky by going into window, then render settings and in here this panel I had to make sure it was rendering in mental ray and that I had set the resolution to 640x480.
I then clicked on create physical sun and sky of which puts three arrows in the centre on the grid, here you then rotate it to what angle you want the sunlight to come from.
From there you simply click on the quick render icon and then you have to wait.
I finished painting all the grass and trees into my 3D environment however, in order to render this you have to convert all the paint effects into polygons otherwise they become invisible to the camera.
So you have to select all of the paint effects, of which is easier to do by using the outliner window. Once you select them all click the modify tab, go down to convert then click on convert paint effects to polygons and then you are ready to render.
However, paint effects do cause alot of lag and it can take a while for this to process the conversion of paint effects to polygons.
