I recently edited a project where I had mixed footage (720 and 1080p). I dropped the footage into a 720 24fps timeline without checking default scale to frame size in the general prefs. Long story short, the 1080 footage isn't scaled correctly and the whole project has been edited (music video). Whats the quickest/most accurate way to go back and scale all the 1080p footage to 720 in the timeline?
