YouTube not working for me.

I have been trying to upload a video for EDM 310 over the past few days and I have been extremely unsuccessful. It was the video for my interview with another USA student about technology. I tried to upload it on YouTube because that is how we have been uploading videos in class. Uploading it straight to the blog post never works...I guess because it is such a large video...6 minutes. I do not know what to do to upload my video but I will continue to try with YouTube as I search for new programs that would help out too. UGH!
