From Wikipedia: "Developed jointly by Sony and Panasonic, the AVCHD 1.0 format was introduced in 2006 primarily for use in high definition consumer camcorders. Favorable comparisons of AVCHD against HDV and XDCAM EX solidified perception of AVCHD as a format acceptable for professional usage. Panasonic released the first professional AVCHD camcorder in autumn of 2008, followed by Sony in the first quarter of 2010.
In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s modes (AVCHD Progressive) and stereoscopic video (AVCHD 3D). The new modes also allowed higher system data rate than existing modes. (AVCHD 2.0)
AVCHD and its logo are trademarks of Panasonic and Sony."
I looked up the specs for your camera and did not fully understand Sony's description of its version of HD. But, I didn't see where it would do 1080p60. I think it does a lesser version of HD.
You can read the rest of the details about AVCHD with either a Google search or Wikipedia search. It gets technical, but in simple terms it is about containers, codecs and formats. The idea is to efficiently collect video data in files that can be used by players and software. "Compression" is involved to keep file sizes lower. Compression is good for keeping file size down, but bad for preserving detail, especially where motion is involved.
You probably know this part, but HD comes in flavors of both "interlaced" and "progressive" with various numbers of vertical lines and frame rates. With progressive all the horizontal lines in each frame on the TV are replaced. Interlaced is left over from CRT TVs and alternate lines are updated with each frame. So with 1080p60 you get all 1080 lines updated in 60 frames per second. With that setting selected, you get the least amount of compression. In other words, the picture quality is as good as it gets until the consumer electronics industry invents all new TVs (again).
