Hai I've been uploading youtube videos for roughly about 2 years now, and I've constantly had this problem with my minecraft videos. I almost always have black bars on my videos. If you need to see an example, here you go. I use fraps for recording, and either I can use Vegas 12, Camtasia Studio, or Windows Movie Maker of course. I CAN make my videos not have black bars, but this requires for the screen to be stretched, and leaving somewhat of an eyesore. If anyone has a solution to this, please tell me! Thanks!
