i'm having truble editing a video with adobe premier if i play the video everything looks fine but when i put the video in the sequence (in the upper right corner), it dosen't show the video, it just plays the sound but the video is all black, i can do everything to it but it just dosen't show the picture if i export (save) the file the picture is all messed up just these lines flicker all the time however there seems to be no truble with other free programs so it must be something i need to configure?
