To best use WMV files on Mac OS X you need to download the WMV codecs for QuickTime from Microsoft's web site. They are called "Windows Media® Components for QuickTime" and are made by Flip4Mac and includes most WMV codecs. The free download handles most codecs, but to handle WMV Professional you need to buy their pro upgrade. The MSS2 codec used for Windows screen recordings is not yet supported.

Important: When you have installed the WMV Codec you need to quit and restart File Juicer to use it. This feature also require Mac OS X 10.4 “Tiger”

Extract or Convert

Conversion to QuickTime is the most popular need for WMV files. Since File Juicer 4.7 it can now convert WMV files to QuickTime and it will use QuickTimes built in encoder and the WMV codec to make a QuickTime move which is as close to the original as possible.

File Juicers other features are to search and extract files from within files without conversion. It preserves the original format which was used when the image or video clip was first put into a file. If a WMV is placed in a Word document, or a PowerPoint slide show, File Juicer will extract it again as a WMV. If a JPEG was put into a PDF file, it will be extracted as a JPEG (because PDF's store JPEG files unchanged).

If you put a JPEG-2000 file into an MP3 file as album art with iTunes, iTunes will convert it to PNG when storing it in the MP3. You will get PNG out if you drop the MP3 onto File Juicer.


Some AVI files can be played by QuickTime Player, others may require a codec for playback. One example of an extra codec is:3ivxD4 at VersionTracker.
AVI and ASF are wrapper formats which contain the the actual data, which may be WMV data or Divx which QuickTime does not support as default.

Screen Recorders

Snapz Pro can record what's on your screen. Play your file in the media player needed, and record it as QuickTime format.
It may require that your Mac which is not doing much else while recording.
There may be more recorders which can do this too.

How to convert a WMV or ASF file to QuickTime with ffmpegX

This is one way I have done it several times, but I no longer recommend it. It is too involved, as the audio and video tracks needs to handled separately.

It will not work with the newer WMV3 encoded WMV files (for Microsoft Media Player 8 or newer). File Juicer will identify wmv3 files with giving them a ".3.wmv" extension.

  • Get ffmpegX.
  • Get mplayer, mencoder and mpeg2enc which ffmpeg needs. Follow the instructions built into ffmpegX.
  • Get the 3ivx codec (free for testing purposes) for QuickTime and install it. It comes with an uninstaller too, but it is just a QuickTime plugin which is put in /Library/QuickTime.
  • Drop the WMV on ffmpegX and convert it to AVI/DivX as it suggests. This will play in Movie Player without audio.
  • Now convert the same WMV to mp3 - just flip the destination format to mp3, and convert.
  • If you get this far and have separated audio and video working - get Quicktime Pro.
  • Open both the mp3 and the AVI file and select all the audio, and copy it.
  • Use QuickTime Pro's "add to selection and scale".
  • Save in the QuickTime format of your choice. The 3G mobile phone format or h164 has a good chance of getting the file size down to the original WMV without loosing too much quality. WMV is a variant of MPEG4 so if you save as MPEG4 you may need to save the file a little larger not to compromise quality
