Okay, you can do this with a few apps, but you wont want too. Upsizing video and image does nothing but add more pixels between the original ones, but of the same colors. what this means is that you will have a fuzzy, ugly, blurred, headache provoking video that will take up 4GB instead of 400MB. So in all actuality this is impossible. You cannot upgrade video or audio, only downgrade it. Although if you want to play the video on a 1080p or i, then just play the original file, it'll save space, time, and stress.
