  Compression Artifacts

  Posted by Smkitchens on December 13, 2005 at 3:23 pm

  Hi,

  I’m being forced to use compressed video from a CD and edit in new shots to create an interactive presentation in Flash. The video was compressed using Cinepak. They look ok when I import them into After Effects 5.0 but when I drage them to the timeline I start seeing a large number of black or white pixel artifacting. I realize the best solution would be to go back to the original video, but unfortunately it’s been lost so I have to make the best of what I have. Is there any way to optimize what I have or to remove the artifacting?

  Thanks,
  Mark

  I believe the technical term for this is “You’re hosed.” CinePak compression is an extremely “lossy” codec and is considered to be one of the most destructive codecs out there.

  Sorry.

  You’re welcome.

  Just for the record, CinePak heralds back to the early 90s and was designed to allow the old 1x CD-ROM players to handle the postage-stamp sized video that was around at the time. Over the years, it has been updated some but it is still the core that traces its heredity back to the 1x and 2x CD-ROM players.
