Go-to-meeting, the online collaboration and screen casting tool produces video using its own special codec, the g2m3. It makes for really small files, but is not a standard codec installed in any kind of video editing package.
All is not lost. Go-to-meeting provides this codec on their site for windows media player. Copying the codec files into your favorite video editor’s codecs folder will enable it to read these files. For this example, I’ll be using the free version of the ‘any video converter’.
Install both the gotomeeting codec from their site and the ‘any video converter‘.
The go-to-meeting codec installer will place the codec dll files here:
Copy the DLL files into the codecs folder of the ‘any video converter’.
C:\Program Files\AnvSoft\Any Video Converter\codecs
Now avc will be able read and work with these files.
Thanks to the owner and viewers of the smartbear blog for pointing me in the right direction.
