well there is nbobody better to ask than the creator of the video. he does not know...
the airfield or map is a mod.
the mustang as well.
the sounds are edited in the video, dont know about the engine sounds.
effects are custom
the whole video is edited in a movie making program - what you see is not straight from the game at all.
camera pointing at the tail in 0.48 is from the PAT mod, therefor game is version 4.09
please be more specific. what are the differences between your game and the video? what do you like better in the video?
then we could figure out what to recommend you...
one more thing...
a good reference to what is possible, is to look in the screenshot section, the screenshot contests, they are specified to NOT be edited.
Youtube videos often are, making you dream of imagery that might not be possible (lighting, colors, shades, sounds...)
