Putting a movie on the Web
The Internet is an exciting place to share your movies, but there are a few things you need to
watch out for. A short three minute vacation video can easily take up 60 MB of disk space and
many hours of download time. But at a reasonable file size, viewers can download your
movies on the Internet. Effective use of video on the Internet requires very high compression
ratios that usually result in very low quality movies. This means your movie should use a small
window (320x240 or preferably smaller), low frame rate (15 fps), and radio quality mono
audio (8 bit). Videos with a lot of motion or action are not well suited to this medium.
Compressing video
for the Web
When putting video on the Web, you have to
consider that it is going to be played on
someone else’s computer. It is therefore
advisable to use codecs found on many
computers. Cinepak and Indeo are good
choices.
MPEG-1 is the de-facto format for video on
the Web. It is currently used in VCDs and
provides high compression ratios without loss
of quality. This is an excellent choice not only
for the Internet, but for all movies that you
plan to play on your PC.
Streaming video is also a good way to
display video on the Internet. This allows
your video to begin playing while still down-
loading. VideoStudio supports RealNetwork’s
RealVideo (*.RM), Microsoft’s Advanced
Streaming format (*.WMV, previously
named *.ASF or *.ASX), and Apple’s
QuickTime (*.QT or *.MOV). These are the
formats popularly used on the Internet.
