how to rotate and save video with minimal changes to video??

[Young Grasshopper]

i recorded an in-car video on my canon powershot elph 300 of me driving my car on the track. i used one of those suction mount things on my sunroof. the problem is the video is upside down and i need to find a simple way to flip it with minimal changes to the quality of the video. i tried googling this and found a tutorial using windows movie maker but it adds these huge black borders to my video and the file size ends up being half of what it was(file size is 2.50GB). the video is also 1080p. anyone have an idea on what i can use for this?

thanks

Sony Vegas can do this.

i did download and install this but it seems like when i 'render' the video the file size of 8x times as large.

There is a youtube option, quality is pretty much kept the same, at least on my 720p camera
