I'm looking for the maths to calculate the needed image size when using normal images for import to use as still images in Premiere.
The images I have are 72dpi and 240dpi. The footage is Black Magic 10 bits AVI 1920x1080 (1,0) 50i and some stuff is 25p (for keying purposes).
I use Photoshop, Illustrator and Fireworks. I have the same question concerning the import and sizing of images in After Effects.
The images I have are 72dpi and 240dpi.
That is completely irrelevant for video editing. The only thing that matters is the pixel dimensions. A 240 dpi image on a 4.3"screen is different than a 72 dpi image on a 200" video wall. The math is simple: one to one relationship. So if you edit 1920 x 1080, use 1920 x 1080 pixel dimensions for your images.
Yes but that doesn't answer my question!
Ok I will try that! Thanks! David
