Know progressive download times You should know how long it is going to take to download your
video. While your video clip downloads, you might want to have other content that appears and
"disguises" the download. For short clips, you can use the following formula: Pause = download time
- play time + 10% of play time. For example, if your clip is 30 seconds long and it takes one minute
to download, you should give your clip a 33-second buffer (60 seconds - 30 seconds + 3 seconds =
33 seconds).
Use clean video The higher the quality of the original, the better the final result. Although frame
rates and sizes of Internet video are usually smaller than those of television, computer monitors
have much better color fidelity, saturation, sharpness, and resolution than conventional televisions.
Even with a small window, image quality can be more important for digital video than for standard
analog television. Artifacts and noise that would hardly be noticeable on TV can be quite obvious on
a computer screen.
Remove noise and interlace After you capture your video content, you might need to remove noise
and interlacing.
Follow the same guidelines for audio The same considerations exist for audio production as for
video production. To achieve good audio compression, you must begin with clean audio. If you are
encoding material from a CD, try to record the file using direct digital transfer instead of through the
analog input of your sound card. The sound card introduces an unnecessary digital-to-analog and
analog-to-digital conversion that can create noise in your source audio. Direct digital transfer tools
are available for Windows and Macintosh platforms. If you must record from an analog source, you
should use the highest quality sound card available.
