Hi! My question is about math actually. We all know that native size of a 720p frame is 1280x720 considering pixels are square. We also know that DVCPROHD stores frames as 960x720.
But if we open a DVCPROHD .mov file QuickTime will display it as 1248x702 meaning these dimensions are correct to display DVCPROHD's frame. So can anybode tell me *what dimensions are really correct*?
I need dimensions of the source frame to calculate correct downscaling proportions to make a PAL 4:3 movie from DVCPROHD 720p, using only one Shake node (Resize) instead of simple combination of two: Fit and Resize; trying to optimize
Another thing that we have to take in count when doing such conversion is that PAL 4:3 720x576 frame have 1.066 pixel aspect.
So, any ideas?
