AVCHD Resolution and Media
The AVCHD format records video at a range of resolutions including 1080p, 1080i, and 720p. Many AVCHD camcorders that advertise themselves as full HD models record HD video at a resolution of 1080i. AVCHD uses 8cm DVD media as the recording medium, but it is designed for Blu-ray Disc compatibility. The DVD format was chosen for its lower cost. The AVCHD format can also use SD and SDHC cards or hard disk drives if your camcorder supports them.
Features of AVCHD Format
AVCHD camcorders record high-definition video on random access media: DVDs, hard disk drives, memory cards, and thumb drives. AVCHD format cameras record long high-definition videos using the MPEG-4 AVC/H.264 format for highly compressed HD recording. An AVCHD video camera connects directly to a high-definition TV or another compatible playback device with an HDMI port. It can also connect directly to a Blu-ray Disc player, Sony PlayStation and to Windows computers running supplied software. Using the AVCHD format, you can burn the high-definition video onto a standard DVD disc. That DVD disc can then be played in a Blu-ray disc player, allowing you to view your high definition video on an HDTV. So even if you don’t own a Blu-ray disc burner, you can still play back your high definition home movies on a Blu-ray disc player or a Sony PlayStation. In addition to video and audio, AVCHD includes media presentation features for menu navigation, slide shows and subtitles.
