AVCHD Lite was introduced in January 2009, as a subset of AVCHD, it is limited to 720p60, 720p50 and 720p24 and does not use the common Multiview Video Coding. By duplicating each frame of 25fps/30fps videos recorded by the camera sensor, AVCHD Lite cameras produce 720p50/720p60 bitstream which are in line with AVCHD and Blu-ray Disc specifications. Till 2013, AVCHD Lite seems to be kicked out of the river and replaced with other formats. A typical example is the Panasonic DMC FZ-200 which can offer AVCHD Progressive recording mode (50fps/60fps acquisition and stream rate) as well as MP4 mode (25fps/30fps acquisition and stream rate).
Cyberlink PowerDirector is capable of editing AVCHD Lite natively. Without transcoding, intermediate codecs or proxy files, using a patented technique (SVRT), Cyberlink PowerDirector 8 can edit AVCHD clips without quality loss.
VideoStudio Pro is able to edit HD AVCHD Lite videos as well as other HD videos. it does not open an individual AVCHD file but import clips from a folder. A pity is that when dealing with AVCH files, this program seems to be a little sluggish.
Sony Vegas Studio, another professional video editing program that can edit HD videos, but can only edit AVCHD files acquired by Sony cameras.
