An mpeg-2 video file is playable using Microsoft's
Media Player on a reasonably powerful modern PC, with the correct
codec installed.
You can then play it like any other video file. Click and go.
No special hardware or special graphics card is needed.
What is a DVD file?
A DVD file is simply a high quality mpeg file, mpeg-2 to be precise.
Regular mpegs you see on a pc are usually mpeg-1 or increasingly
mpeg-4 for streaming from the web. While these are relatively small
files, they are slightly blurred.
DVD mpeg-2 looks great by comparison.
DVD files are also bigger and need more disk space. At least two
or three times as big. Every minute of DVD runtime uses 30mb of
diskspace. So 10 minutes of video takes 300 mb, enough to easily
fit onto a cd or hard disk.
DVD files will play from hard disk and can be kept on cd-rom.
What's the difference between mpeg-2 DVD and the DVD disks we buy in the shops?
A DVD disk is a versatile storage medium that can hold 4.7 gigabytes.
So a 90 minute movie requires around 3 gigabyte of storage space.
And the disk has a front end interactive menu, which includes an
intro sequence, interviews with stars, movie trailers, and a small
file so that the DVD player can recognise the disk.
Corporate video however usually requires nowhere near the 3 gb
that a full length movie requires.
This makes corporate DVD a much more flexible medium to use, as
a dedicated player is not required.
All that's required is to install a codec on a PC that has Microsoft
Media Player.
Is it expensive to have my corporate video on DVD?
No.
Normally between £200 and £500 depending on its length,
and the extras you may require, such as a front end interactive
menu badged to your corporate logo and image.
