The G2M3 codec is a codec that GoToMeeting uses. Not all computers, including Macs, can play videos encoded with the G2M3 codec. To convert videos encoded with the G2M3 codec into the normal WMV video codec so that any computer can play it, you need to download the Window Media Encoder and convert the video file.

Here are the steps:

  1. First, download and install Window Media Encoder
  2. Go to Start Menu > Programs > Windows Media > Windows Media Encoder
  3. Choose to “Convert a File”
  4. For the Source file, browse to the WMV video file that you want to convert
  5. Choose “File Download” and click on Next
  6. For Video, choose DVD quality (1Mbps VBR) and for Audio, choose CD quality (VBR), and click on Next
  7. Click on Next again, there will be no changes on this screen
  8. Uncheck “Begin converting when I click Finish”, and click Finish
  9. Click on Properties > Compression > Edit
  10. Select everything in the Bit Rates box and click Edit
  11. Check the box that says “Same as video input”
  12. Click Ok > Apply > Start Encoding
