  Problem with Moire/Scaling in AE

  Posted by Lukas Thorsson on May 11, 2009 at 11:23 am

  Hi there,

  we’re doing a high def presentation for some display vendors. the presentation consists of some well done taken fotos moving smoothly through the screen.

  as this is for a display vendor the top priority is the quality of the clip. now the prob:
  most of the fotos looking great, but in some of them – in very detailed (e.g. hair) areas – occurs kind of a rustle. i think its an interpolation problem through the time, but how should i solve it?
  motion blur is already turned on, und i also tried 0.5 flicker reduce.

  um btw: output format is 29,97i in h264 25mbit

  any idea would be great!

  You’re scaling 3k images down to about 1k so two out of every 3 pixels is being thrown away or smooshed. Sometimes they end up existing only one of every two frames (or one of every 2 fields).

  You’ll need to apply about 2 pixels of vertical blur. Like anti-aliasing, the illusion of clarity is enhanced by making the image less distinct.
