  h.264 exports blocky on fades up/down

  Posted by Chris Borjis on January 4, 2013 at 11:00 pm

  I’ve searched and not found an exact fix to this:

  poor looking macroblocking of a pristine image on a fade up or fade down.
  sometimes on cross fades.

  using a bitrate of 5,000kbps should be plenty.

  I’m now using Handbrake of all apps, to get clean files for my client.
  Ridiculous I should have to take that step.

  Is there a fix or workaround anyone knows of?

  running CS 6.01 MAC

  Just an idea, are you exporting using preview renders or is the render at full resolution checked on your export window. Those pesky low renders got me a couple of times. They are useful but they’ll get you at the end.

  What is your keyframe distance? Single or double pass?

  use previews unchecked, highest quality checked.

  also set the bar for 100 quality.

  keyframes: 72

  I’m using AME exporting quicktime with h.264 and the options button
  is grayed out so its likely defaulting to single pass.

  When Premiere uses the Quicktime container, it uses the Quicktime h.264 codec. When Premiere uses mp4 as the container, it uses a different h.264 codec.

  I would suggest using the mp4/h264 option to encode. Both single pass CBR and 2 pass VBR give far better results in terms of macroblocking over Quicktime’s encoder. I even spread the keyframes further to every 90 frames.

  It’s a pretty simple step to re-wrap mp4 to MOV using many tools out there, my personal fave being FFMPEG.

  Premiere def isn’t as robust when it comes to encoding options as anyone would like it to be, but there h.264 encoder isn’t bad.

  how do you access the non-quicktime mp4 you speak of?

  In the format drop-down, instead of Quicktime select H.264.
