Using HP camera the native res is 1440x1080 with 16:9 aspect ratio flag set in the file. I have used these files in my movie stuido 11 without issues. Today I tried one with my new Movie Studio 12 and noticed it added letterboxing to the left and right side of the screen, effectively squishing the video. I did notice in time and as a workaround I disabled the maintain aspect ratio on the video track and now it fills the screen as it should. Any thoughts on this? new bug in the new version or...? IN the meantime I can work around it as I said easy enough, but it should read the aspect ratio int he file. For the record, it is .mov container containing H264 video.
