Lightworks [free] video Pixelated

[Benedikt Brunner]

I made a vdeo with lightworks and as soon as i imported the first file into lightworks i noticed a strong pixelation in the video. How can i fix this ?
here the final video y outube.com/watch?v=hJnQgzwwg9w&list=UUEF7AsQnUynBORsKVfOYKWQ
The upper video is not there for self advertisment. I used it to show the problem. Some of my friends said its completely fine to them but i havent really checked if they just think that the pixelation is ok or if it really IS normal on thier screens.
And please dont mind my writing mistakes. Im from Austria ( not australia )

Looks fine. You will notice it look bad if you make it fullscreen on a 1080p monitor, but that's because it's a 720p video.

1.
I dont even have a full hd screen. Its only 1600x900...
2. Well. If it looks fine i will keep using this software and if i actually make it into a network like Fullscreen and start making enough money to pay the bill for the pro version i will buy it.
