Digital Camcorder..Formats :
MICROMV and tape compared to miniDV and Hi8 tapes Digital Tapeless: Low-end digital tapeless systems often use an MPEG-4 codec and flash memory; high-end versions, on the other hand, store video data to hard disk or optical disc. H.264 codec based AVCHD format, which records MPEG-4 AVC (H.264) compressed video to various kinds of tapeless media (hard disks or hard drive recordable optical discs, flash memory, sd Memory , etc).
DV codec based:
MiniDV camcorder and several derivatives, including DVCPRO from Panasonic and DVCAM from Sony. DV records the highest quality pictures (generally agreed to be at or near broadcast-quality) on DV tapes that are easily transferable via Firewire or USB to personal computers.
Though designed as a consumer standard, there is extensive use of MiniDV in low-budget film and television 
production. Digital8 camcorder , that uses Hi8 tapes (Sony is the only company currently producing D8 camcorders, though Hitachi used to). Some models of Digital 8 cameras camcorder have the ability to read older Hi8 analog format tapes. The format's technical specifications are of the same quality as MiniDV (both use the same DV codec), and although no professional-level Digital8 equipment exists, D8 has been used to make TV and movie productions.

MPEG-2 codec based:
MICROMV: Uses a matchbox-sized cassette. Sony was the only electronics manufacturer for this format, and editing software was proprietary to Sony and only available on Microsoft Windows; however, open source programmers did manage to create capture software for Linux. The hardware is no longer in production, though tapes are still available through Sony.
DVD: Uses either Mini DVD-R or DVD-RAM. This is a multi-manufacturer standard that uses 8 cm DVD discs for 30 
minutes of video. DVD-R can be played on consumer DVD players but cannot be added to or recorded over once finalized for viewing. DVD-RAM can be added to and/or recorded over, but cannot be played on many consumer DVD players, and costs a lot more than other types of DVD recordable media. The DVD-RW is another option allowing the user to re-record, but only records sequentially and must be finalized for viewing. The discs do cost more than the DVD-R format, which only records once. DVD discs are also very vulnerable to scratches. DVD camcorders are generally not designed to connect to computers for editing purposes, though some high-end DVD units do record surround sound, a feature not standard with DV equipment.

HDV: Records up to an hour of HDTV MPEG-2 signal roughly equal to broadcast quality HD on a standard MiniDV cassette.
