Frequently Asked Questions

General FAQ
Creating a VideoCast FAQ

What is NIH VideoCast?

The Center for Information Technology (CIT) makes special NIH events, seminars, and lectures available to viewers on the VideoCast web site. VideoCasting is the method of electronically streaming digitally encoded video and audio data from a server to a client. Streaming files are not downloaded, but rather are broadcast in a manner similar to television broadcasts . The videos are processed by a compression program into a streaming format and delivered in a staggered fashion to minimize impact upon the network and maximize the experience of the content for the viewer. When users request a streaming file they will receive an initial burst of data after a short delay (file latency). While content is being viewed, the streaming server machine and software continues to "stream" data in such a manner that the viewer experiences no break in the content.

I'm using slides. Will they show up clearly on the VideoCast?

Slides can be hard to read on a VideoCast screen. Some ways of alleviating the problem are to:

  • Set your font as large as possible.
  • Use 24pt type or larger for bulleted items and any additional text on the slide, with 30pt type or larger for headings.
  • Have plenty of white space between groupings of text.
  • Avoid more than three bulleted items on a single slide.
  • Make graphics as large as possible, but try to keep your slides uncluttered.
