I'm sure this is a super newbe question from a guy that should know better but here goes... I'm doing some talent audition videos where I have to add photo's along with video. Basically photo stills of my performer over video of the performance. These will be shown on Youtube or Vimeo at 720p. Should I use pan and crop to resize these photo's or should they be resized with photoshop prior to putting on the vegas timeline. If photoshop is the preferred method, to what resoulution should they be resized?
