to mechanical damage in case of being dropped. Most new computers, many TV sets and Blu-ray Disc players, as well as many personal portable media players have built-in card readers and can play AVCHD video directly from a card. Cons: More expensive per minute of recording than a built-in HDD or DVD media. Not reliable for long term storage and may wear out more rapidly than expected, especially the cards made with MLC technology as opposed to cards using SLC technology. Vulnerable to electrical damage, such as static discharge, and too high temperature. A bad memory card can cause data corruption, causing loss of one or more clips. Non-removable solid-state memory Some AVCHD camcorders come with built-in solid-state memory either as a sole media, or in addition to other media. Pros: Allows making a camcorder smaller if no other media is used. Always available for recording, in case other type of media is full or missing. Cons: Because recording media is non-removable, the recorded images should be backed up either to a computer with a USB cable to transfer video or (if the camera accepts them) to another FLASH card or even a DVD or Blu-ray through an externally connected burner. Usage of an AC power adapter may be required. Non-removable media cannot be shared, sent or stored separately of the camcorder. If damaged or worn out, non-removable media cannot easily be replaced like a memory card. Branding Panasonic and Sony developed several brand names for their professional as well as simplified versions of AVCHD. AVCHD Lite AVCHD Lite is a subset of AVCHD format announced in January 2009, which is limited to 720p60, 720p50 and 720p24 and does not employ Multiview Video Coding. AVCHD Lite cameras duplicate each frame of 25fps/30fps video acquired by camera sensor, producing 720p50/720p60 bitstream compliant with AVCHD and Blu-ray Disc specifications. As of 2013, AVCHD Lite seems to have been all but replaced with other formats. For example, the Panasonic DMC FZ-200 offers AVCHD Progressive recording mode (50fps/60fps acquisition and stream rate) as well as MP4 mode (25fps/30fps acquisition and stream rate). AVCCAM Formerly known as "AVCHD with professional features," AVCCAM is the name of professional AVCHD camcorders from Panasonic's Broadcast division. Some of these professional features listed in early Panasonic advertising materials included 1/3-inch progressive 3CCD sensor, XLR microphone input, solid-state media and capability of recording at the maximum AVCHD bitrate - 24
