Making good presentations — Overview

There are a few very key elements to making a good presentation even better.

There are two things that you must always remember about an AV application:
  • AV means Audio Visual

    Make sure you have good audio and good visual. A great video with poor audio input will sound unprofessional. You must always make sure you have both good audio and video.

  • Garbage In = Garbage Out

    The better the input you give Wirecast, the better quality your viewers will see. Spend the time to get your input right, as it will make a huge difference to your viewers.

Why is this?

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, it will be 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 quality audio and video to the compression process as possible.

In Wirecast, this means to make sure that what you see in the Live area is the best you can make it look. Wirecast takes exactly what you see in that area and sends it to the codecs.
