  On2 Flix Pro settings

  Posted by Video J 401 on April 15, 2007 at 6:07 pm

  Hello everyone,

  I currently use Flix Pro v8.52 to encode videos that avg 1 – 3min ea. (music videos)
  I am looking to get higher quality video & audio @ lower bitrates.
  I have an Intel based Mac Pro, (2) dual core 3.0GHz Xeon processors, 4GB of RAM…
  My videos seem to be limited to 300 total bitrate (260 video, 40 audio) & 15 fps to be smoothly played on an older Pentium 3 PC (451 Mhz processor, 256 MB RAM, wireless, cable modem). Higer bitrates make the video play choppy, but @ the 300 total bitrate, the video is not choppy, but only comparable to YouTube quality.
  History.com provides high quality video on the Pentium 3 machine, how do they do it?
  Do they use a different encoder, like Kulabyte?
  Do I just need to have the correct settings in Flix Pro?

  Here are the seetings I am using…

  480×360 output dimensions
  260 maximum video bitrate
  20,050 Hz audio
  40 kBits/s
  2-pass VBR
  60 keyframes
  deinterlace
  cropped to 704×480 (4:3 aspect ratio)
  “Good” quality VP62, 75% CPU

  Any help would be much appreciated.
  Thanks

  I’d say you should be using a maximum frame size of 320×240 at that bitrate.
  can you clarify what your keyframe setting is? – Generally it should be at 10x the frame rate – or in your case every 150 frames.
