  ideal graphic resolution

  Posted by Dan Cooper on June 2, 2007 at 8:34 am

  I’m curios as to the ideal resolution for graphics to be imported into AE projects (say from Photoshop) that look great but work efficiently, intended for broadcast.

  Print is 300dpi, screen 72, where does AE stand? (oh and working in 720 x 576 PAL specs)

  Cheers,
  Dan

  After Effects, and just about all video-related programs, expect 72dpi files. There isn’t much choice in the matter.

  It depends. You have to do some math.

  For the sake of calculations, consider your screen as 800×600 pixels. If you expect your scanned image to fill the screen, you want it to be 800×600 pixels when scanned.

  To get the DPI (or pixels-per-inch) number, do this for a horizontal image: widthxDPI=pixel width.

  So:
  A picture 8″ wide would have to be scanned at 100 DPI to give an image 800 pixels wide.
  8″x100dpi=800 pix.
  or 800/8=100dpi.

  Now if you wanted to zoom into a 4×3 inch section of that picture, then you would want that 4×3 inch area to be 800×600 pixels:
  800 pix/4″ = 200 dpi.
  You see? Because you’re zooming in closer, you want more detail, so you have to scan at a higher dpi.

  I’ll leave it up to you to figure out how to scan vertical shots and shots that are wider than 4×3. Just remember: it’s okay to go with a slightly higher DPI for good resolution, but if you go too high, you get a really big image that could slow down your work.
