I know you said you wanted to make a video fast so its a bit sketchy, but I would never think like that, it doesn't matter how long it takes, as long as your video is up to a good standard and edited well, you'll gain yourself viewers, I would start by trying to make the video fit the screen. Having a good standard in video quality and content will gain you viewers who will like and watch your videos. Other than that, keep going and doing what your doing, just try and take your time on your uploads. I hope I helped :3
