Recently I've been getting all 4 sides of my movies chopped of when putting them on youtube. What can I do to make sure that I get 100% frame without getting it cut out?

I'm using iMovie with GoPro HD recording at 720p at 30 fps. I lose tons of quality with encoding too.

What should I look for when encoding and making sure the whole video fits?

Here's the video I've made:

i've never used iMovie.
what are the dimensions of your video that is output from iMovie? the file size? What are you using to encode it for upload? or are you just uploading that file?
use something like mpeg streamclip to encode your final movie for web upload with these settings:
export to mp4, h.264 codec, unscaled (720p), then choose a bitrate (like 5 or 10 Mbps).
