AVCHD Lite is a subset of AVCHD format, which identifies devices that are capable of 720p recording only. The new "AVCHD Lite" Logo and the "AVCHD Lite" License are restricted to devices within the AVCHD Video Camera category. Digital cameras have been added to the AVCHD Video Camera category.
At this time Studio 12 does not support the AVCHD Lite format. Support for this format will be added to the next Studio release.
