82 PHOTOGRAPHY
computer-based editing. Computer-based editing is
currently the preferred method but it does require a
high-specification computer with a large hard drive, as DV
tape uses typically around 13 gigabytes of space per hour
at full resolution. Chosen footage can be captured on a
computer using the ‘firewire’ (IEEE 1394) connection on
the camera, which enables fast data transfer, and many
computers come with a firewire input.
Adobe Premier and Windows XP can be used for
capture and editing, providing the computer has a cap-
ture card. There are, of course, other suppliers of capture
hardware and software and editing software. Amongst the
professionals, Apple Macs and Final Cut Pro are highly
rated for all forms of editing and image processing.
Windows XP Movie Maker is good for making quick
movies but the editing suite is not as sophisticated as Adobe
Premier. However, Movie Maker is quite good for saving
the finished video to various formats, compressions and
quality levels (e.g. to CD or for the internet). For opti-
mum quality, export the video back to digital tape or use
appropriate software to make a DVD. In this instance, the
video files are transformed into a different format, which
can only be played through DVD software on a computer
or on a domestic DVD player.Further Information
