15.5 CAPTURING THE STREAM
TriCaster™ archives your live stream file as it is created. A new folder will be automatically
created as needed (at D:\Media\Clips\sessionname\SavedStreams) to receive the captured
stream file. (You have the option of deleting the file on completion of a streaming session if you
wish.)
15.6 STREAMING STRATEGIES
One of the best approaches when beginning (to stream your productions) is to establish a
relationship with a commercial streaming media provider. A good provider can guide you past
firewalls, provide public addresses for everyone to view your stream, and provide no end of
valuable guidance.
And it may not be as expensive as you think (costs vary based on considerations such as how
many viewers you expect, how much web bandwidth you use each month, and so-on). Some
services based on an advertising model will even host your stream free.
15.6.1 ON DEMAND OR LIVE?
Not all ‘streaming’ is ‘live streaming.’ The difference is similar to i) watching a television program

On demand streams are stored on a server (often supplied by an external service provider),
ready to be transmitted whenever a viewer wishes. Live streams are available at the time they
are broadcast, such as during a live concert or event.
ON DEMAND HOSTING
TriCaster™ permits you to record live productions to a local hard drive. The resulting files can be
hosted on a network later, so viewers can connect whenever they like. If you have the resources
available, you can host the video yourself – but if many people will likely want to view your
production, you will likely avail yourself of a service to stream it on your behalf.
Ideally, ‘on demand’ streaming video begins to play on request after a few moments. (Letting the
stream get a bit ahead of the client playback device is called ‘buffering’, and helps ensure smooth
