Authoring tools for mpeg4/h264 avc exist?

[vsv]

Creating Interactive Video with HiDef MPEG4/h264 avc using MP4box today just impossible...
Do you know another commercially available tools?

Thank you in advance

i am not sure whether mp4box already handles .mp4 files that already contain avc

envivio offers commercial tools with systems and avc support in .mp4
