  CS4 Export keyframe rate 0?

  Posted by Josh Figatner on July 1, 2010 at 3:05 am

  Hello beloved Cow Community,

  I’ve got a 12 min short film shot in 1080/24p (didn’t use 24PA, next time- hpx170). Starting to do some render tests and the best size/quality/smooth playback settings for me so far has been WMV.
  I’m curious if my settings are overkill:

  WMV 9 Advanced, CBR 2-pass, 1920×1080, 24fps, square pixels, 10,000 kbps

  Keyframe rate: 0
  buffer size: unchecked.

  My question is, if my keyframe rate is 0, does that mean every frame is a KF? The next lowest value is 1, and I’ve had bad experiences with a KFR of 1 in that the video will pulse every second as a new keyframe is displayed. Also had similar experiences with VBRs. Perhaps my datarate is a bit high, though if I turn it down too much, I start to see aliasing and pixelation… sigh. Also, what’s the deal with the buffer size? should I engage it or not?

  Thanks for your input,

  Josh

  Ok, I think I figured out a lot of the above ranting:

  Instead of trying to venture off on my own, I wound up retrying the WMV “HDTV high quality” preset with very few modifications and it resulted in a clean export. I still haven’t found out what a 0 Keyframe Rate will do though…

  Also, in theory, wouldn’t a 1 KeyFrame Rate result in a larger file than a 5 KFR?

  Get to the choppah!!!
