The best way to understand High Definition
is the image has a higher resolution allowing a viewer
to see more of the picture at a better quality. At SPF
Transfer we have the ability to capture DVCPRO HD over
FireWire then once the project is cut we can output
over FireWire with no degradation of quality loss. Some
edit houses will force recompression using some HD codecs.
