I make very stupid videos for You Tube which include graphics logos and text and of course include videos from other users but when i import a youtube video which i convert to quick time movie format i get this very small size in the preview monitor even when i render it to a bigger format i still get it smaller than the size that i put it in? Whats going on why cant i view videos downloaded from youtube/internet and converted to quick time as their full size? I get this small size whats going in premier?
You are downloading a 320X240 video and are probably putting it in a 720X480 project. Of course they are too small. Use the Motion effect to scale them up. It will look bad, but garbage in, garbage out.
