584 21. Creating Output for the Web

This means you can save enormous amounts of space and bandwidth.
Because Presenter uses much less space and bandwidth it is free to use
higher resolutions. Most Presenter shows you see on the web are at least
640 x 480, if not larger.

Presenter isn’t just used for web playback. It’s also used to preview a show
while you’re making it and to watch an Executable or Autorun CD show.
Presenter is used any time you view a show that isn’t in video form.

Presenter is automatically installed for you when you install ProShow. If you
share a show using Presenter with someone who does not have ProShow
they will receive a prompt to install it when they try to view the show.

The process for installing Presenter is painless. The viewer only needs to
allow their browser to install it and the rest is done automatically.

A Note about Presenter

The most unique aspect of Presenter is that it renders the show in real-time.
What this means is that every moving image and fading transition is being
calculated by your PC as it plays.
Video files are rendered in advance which is why they take so long to create.
All of those frames must be drawn, put into order, saved, and compressed
to make the video file.
Presenter does all of that on the fly. This is why you save so much space
and time using it. There can be one drawback to this method, however.

If a PC doesn’t have adequate resources to play the show you may
experience dropped frames. This means that certain motions may appear
to be slightly choppy or hesitant as the PC ignores certain frames of motion
to keep the show playing without bogging down.
You can help alleviate this by avoiding very high resolutions for Presenter
shows and making sure that there aren’t multiple system-intensive
processes running in the background.
