How often is that goal going on? Can you go into practice mode and score it with a high percentage? Also, goalies are your last line of defense. If this is frequently getting scored on you, it would be good to take control of your D and cover the short side better. In your video, it looks like your opponent had a step on you and easily got this shot off. That doesn't mean it should get scored on every time of course. So, if you think it's an issue with the game, get some unedited video showing it going in at a high rate.
It's best to put clips up on YouTube or published through your console so they can be streamed. Then you don't have to deal with the low file size allowed here.
