I made a video for a review but it seems that it is over the size requirement. I don't know a thing about this stuff. What can I do do make it a smaller file size? A program to download it to convert it so it meets the 1Gb size? I've googled and I just don't know what to do. My video is only a couple mins over the time limit but I've seen videos that were longer on here. I don't get it

I don't have any software, I just recorded the video from my built in webcam on my laptop. less
