I made a video with Adobe Premier and uploaded it to video. The video is really nice quality (the picture is) but when I upload it to youtube its not nearly as sharp. Why is this? Is there a different format I can put it in that will make it sharper when I upload it to Youtube? I just click the export button to get the video to my desktop and I'm pretty sure that puts it in Microsoft .avi or something. How can I make it export in a different format?
