Also, in what category thingy should this post be in on the forums?

I want to know how to get a light color effect shown here on these videos:

I know the quality of the camera is good... But it's not just the quality, or light, is it?
Has he edited the colors or not?

If so, how would you go about doing it?
Are there just pre-set filters on iMovie and stuff that you can apply, and 'bam' that's it?

Sorry if I sound silly

thankyou
