AVCHD 2.0 spec now out with new trademarks
The AVCHD video format specification has been updated at the start of the month, as outlined by the AVCHD Information Web Site. Co-promoters of the format, namely Sony and Panasonic, have approved the new AVCHD 2.0 standard. It now includes 1080p 50FPS (for PAL) and 60FPS (for NTSC) video specifications as well as 3D video.
As such, new trademarks are introduced, including AVCHD 3D, AVCHD Progressive and AVCHD 3D/Progressive. Before this change, both Sony and Panasonic built camcorders that could handle 1080p60 but only out of the official spec. Some apps don't recognize the higher frame rates and won't until patched to recognize the new 2.0 standard.
Higher frame rates help improve the output during fast-moving scenes and also open the door to 3D video that runs at the same 30FPS as regular 2D.
