[M4IF Technotes] Osmo4 and Envivio

Envivio has an authoring tool to create interactive contents. There are
other commercial tools available, but I will let their owner describe
them...

Thanks for the reply,
Just wondering... I have been creating some scenes using MP4tool, so far 
anything I have made has been compliant to both Envivio and Osmo4 (as I have
been generally using MP3 audio). Is there many other methods of creating 
systems content other than writing a .bt file with video/audio/2D nodes and 
using MP4tool?? either commercial or (preferably) free?? I would assume that
there are many tools but so far I have only been able to find one.
Thanks again,
Jim
