  HD footage losing quality in Composition

  Posted by Paul Baker on January 30, 2008 at 8:13 pm

  I was wondering if anyone could help, I’ve been using After Effects for a few months, but I still feel pretty new…

  I am trying to put a 960x 720 DVCPRO HD 720p60 24b quicktime movie that I exported using FCP into a composition in AE cs3. The quality of the quicktime movie looks fantastic, but every time I put it in the comp. it loses quality, with jagged edges, etc..

  I am using this footage for compositing purposes, so I NEED it to look crystal clear..

  any ideas on how to fix that?

  What you’re probably seeing is the effect of the pixel aspect ratio scaling. Turn that off in the viewer (the button that looks like a square with a double-headed arrow) and your footage should be pin sharp again.

  This is a low-quality scaling to give you an idea what your footage will look like when viewed on an appropriate monitor. It’s not what it will look like when rendered.

  Cheers,

  Hi there.

  I’m having the exact same problem with my DVCProHD footage except toggling Pixel Aspect Ratio Correction doesn’t solve it.
  The footage looks fine on its own, but as soon as I put it in a new composition, it gets jaggy. The jagged edges persist on output, both in DVCProHD and Animation codecs.

  Any thoughts?

  I’m running AE 7.0
