Media on the Internet is changing with the adoption
of VC-1 and H.264  directors
and movie studios can provide a high quality stream
to showcase a movie. Most people today see these codecs
when they simple view a movie trailer over the web.
The future will provide a large enough pipeline and
a video codec that will make streaming High Definition
over the Internet a reality. Presently the bandwidth
does not provide full-uncompressed HD so we are left
with VC-1 and H.264. On April 3, 2006, SMPTE announced
the formal release of the VC-1 standard as SMPTE 421M.
This is the codec that was adopted by HD DVD where as
Blue Ray DVD's are using MPEG 2, and are increasing
the bit rate due to the larger storage of the blue ray
disc which can store about 30 gigs on the blue ray disk.
MPEG 2 can achieve HD by increasing the bit rate and
the file size. VC-1 achieves the same quality but with
the ability to de-interlace the footage before you even
digitize the footage, in addition the file sizes for
VC-1 are much smaller then mpeg 2.
The buzz around the industry is about WMV and H.264.
The DivX codec is for clients trying to target both
the MAC and PC world. The reality is WMV and H.264 produce
the cleanest quality for the file size. H.264 files
are a little larger then WMV's but the quality is pretty
equal across the board. At SPF Transfer we are the experts
