  large scale compression

  Posted by Ben Lunden on February 23, 2008 at 11:52 pm

  Hi,
  I have a thirty minute SD NTSC video that I need to compress for the web and ipod/iphone. It needs to be as close to under 100mb as possible. The goal is to have it small enough to be easily downloaded and viewed anywhere.

  I’ve done an ISMA mp4 version of the video (320×240 24fps AAC stereo audio) and it’s alright but the quality isn’t so hot.

  (I used quicktime player to compress from a DV avi premiere export)

  Is some secret to compression that I don’t know? I’ve seen a few videos with great quality and small size but all of mine seem to look kinda crappy when compressed. Is it that the video is just too long to be compressed to such a small size to retain any good quality?

  Any help would be MUCH appreciated!
  -Ben.

  To get the best quality out of your transcoding you really need to get hold of a good dedicated compression application, like Procoder on the PC or Episode on the Mac. Exporting out of Quicktime is simply not good enough.

  As you’re starting with plain old DV you’re never going to get ‘amazing’ quality as DV is already heavily compressed.

  I checked out Procoder and I got a MUCH nicer render. Thanks for the help!
