Overview
There are many ways to make a good live event even better. But this appendix focuses
on two main things to remember about video streaming:
• High Quality Audio Input Great looking video with poor audio input appears
unprofessional.
• Good Lighting Poor lighting can ruin an otherwise excellent live event. If you are
doing chroma keying, this may become the most important part of your setup.
When video is saved to disk or sent over the network, it needs to be compressed. The
compression process is done by encoders (codecs) which are optimized to work with
clean input data. This means that if the audio or video is muddy to start with, it remains
muddy after compression. Some codecs may even highlight poor input because the
algorithm is built to look for differences.
Your goal should be to give the best possible quality audio and video to the
compression process as possible. This means making sure what you see in the Live area
is the best possible quality because Wirecast takes exactly what you see and sends it to
the codecs.
