I'm working on a trade show video for a client and also a series of ad spots for TV. We're only using their footage which is 720 X 480!
I suppose that I can edit on a 720p timeline for the trade show, so at least the footage will be a little larger. There will be lots of picture in picture effects, because I never want the footage to be blown up full screen! ButI'm concerned about the ad spots. Is it safe to deliver those in 720P? Or should they be 1080P?
Well it never hurts to ask the station what their tech requirements are. Though it's often hard to get a straight answer, unless you talk directly to someone in Engineering and not sales. Your region may differ but where I am, even if you submit 1080, it's still converted and delivered to the final audience as 720.
