Advances in SD and HD technology saw the release of the new
HDV format in 2003, using cassette tape in DV specifications
for HD video and audio recording. Designed to be compatible
with DVCAM recorders, the HDV format has become popular in
a wide range of fields, from documentary programs to weddings
and other events.

The first NXCAM in AVCHD format, released in 2010, brought
significant improvements in ambience and picture quality. The
AVCHD format uses MPEG-4 AVC/H.264 compression and
records onto memory cards and flash memory units. Along
with HDTV and Blue-ray, AVCHD can also be used with IT video
formats designed for mobile devices and web movies.
