Finding equivalent x,y position values in HD video
on Jun 13, 2012 at 4:12:04 pm

Hi, I have a video that I changed from 720x540 to 1920x1080. I want the animation of the energy beams in this video to have the same positions as they move across the screen relative to the 720x540 version. For each animation of the beams I have two position key frames. I need to work out what the values for these key frames are for the 1920x1080 version but don't have the maths skills to find them. Here are the values for the topmost beam in 720x540. The beams start and end outside of the shot as they travel into view.

start position

x: 1241.8 y: 278

end position

x: 400.1 y: 195

Is there a way to translate these values to their relative equivalents in HD?

If you use the Scale Composition script (File > Scripts > Scale composition.jsx) and set the new height to 1080, it will scale these values for you.
