  Converting from wmv to h264 – larger file size

  Posted by Gabe Clark on January 9, 2012 at 9:06 pm

  So even though I made every little detail in the export options the same or smaller (I even had a significantly smaller bitrate), the file size is always like twice as big as my original wmv file.

  The original file:

  video
  01:10:00
  1680×1050 (yeah, its a desktop dimension..)
  data rate 4576kbps
  total bitrate 4624kbps
  29fps

  audio
  bitrate 48kbps
  mono
  sample rate 44kHz
  
  263 MB

  Ok so I’m using the following specs to encode:

  H.264
  multiplexing mp4, stream capability none
  NTSC 1680×1050 square pixels
  Main profile level 4.2
  29.97fps progressive
  AAC 48kbps 44.1kHz mono
  VBR 1 pass
  target 3.00 max 4.62 Mbps (with this bitrate it should be a lot smaller right?)

  So yeah.. my file size after exporting is 666 MB (MARK OF THE BEAST O.o)

  Any ideas? These videos are going to be hosted and streamed from our server so the file size needs to be small but they are also pretty high def, obviously I thought H.264. Starting to get a little frustrated.

  Still learning when it comes to video. Any help is greatly appreciated 🙂
