Camcorders differ by recording medium, file types
Like standard-definition camcorders, HD camcorders can record to different media. Each type has its pros and cons:
HD camcorders Flash memory -- lightweight, but cards can be expensive: Camcorders that record to flash memory (SD or SDHC cards, Sony Memory Stick media and/or internal flash memory) are the smallest and lightest HD camcorders on the market; the smallest are no bigger than an iPod. A typical internal flash-memory camcorder might have 32 GB of built-in flash memory, and it will store three to 12 hours of footage before it must be downloaded to a computer. The priciest models double that capacity to 64 GB of internal memory. Some camcorders record only to memory cards; an 8 GB memory card can be had for $15 and will store one to three hours of footage. Most camcorders accept 32 GB memory cards, and some accept special 64 GB cards. Many HDTVs include a memory card slot that will allow you to play your movies directly from the card.
HD camcorders MiniDV -- excellent video quality, but older technology: MiniDV camcorders record to small tapes. The tapes cost about $3 each and hold 60 to 90 minutes of footage. This type of camcorder compresses footage the least, so MiniDV camcorders have traditionally offered the best video quality. However, you must hook up your camcorder to your TV -- or transfer your footage to a computer and burn it to a DVD -- to play your movies. Transferring footage to a computer is extremely slow, because it happens in real time (an hour-long tape takes an hour to transfer). Most experts say other formats have now caught up in terms of quality, and few new camcorders use tapes.
High-def camcorder shoppers will run into two main recording formats: HDV or AVCHD. Most new camcorders record in AVCHD.

Here's what the experts say to look for when buying a high-definition camcorder:
HDV camcorders that record to tapes are on their way out. Although HDV traditionally records excellent video and provides an instant archive, very few new HD camcorders use this medium.
Camcorders that record to flash memory are the most compact. Most new camcorders use flash memory instead of a bulkier, heavier internal hard drive. Internal hard drives can usually hold many more hours of footage, but you can add memory cards to flash-memory camcorders to boost their memories.
