  Compressor rendering artefacts/errors

  Posted by Stephen Abbott on September 3, 2008 at 6:28 pm

  Hello,

  H264 Quicktimes made with Compressor 3.0.3 are generating visual glitches, like this:

  These appear mostly on shots with lots of motion. (This shot is an out-of-focus truck crossing the foreground)

  Source video is FCP QT DVCPRO 1080 50i, output is:
  QT H264 5000kbps 2-pass VBR, 1280x720p, deinterlaced in Compressor at “Better” (with adaptive details), Resize filter at “Better”.

  I’ve tried with no success:
  – altering keyframe and bitrate settings
  – altering resolution (1080p25 has even worse artefacts)

  The machine:
  Macbook Pro 2.5ghz, OSX 10.5.4, FCP 6.0.4, Compressor 3.0.3.

  Any thoughts?

  Thanks for your time,

  Stephen Abbott

  Update:
  The next day the artefacts are gone! No change to compression settings, but:

  – rebooted
  – changed qmaster preferences to use 2 cores

  Strange, but thankfully fixed.
