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.

Video quality is degraded

Video quality can degrade on a wireless connection or when playing video at full-screen. To improve performance, switch to a wired LAN connection. Switch from full screen to normal. Select a specific bit rate such as 740K, 512K or 225K depending on your actual network speed. If necessary, re-boot your computer and try again. If you are experiencing poor video performance on a wired LAN connection, it may be helpful to include a screen shot of the computer's Task Manager, Networking tab, save it as an image in the Paint accessory program, and attach it to your email message. Also, include your IP address along with a screen shot of the VideoCast Test results.

I'm not getting sound

Check your speaker volume and mixer settings. Make sure sound is not set to mute speakers or see if audio levels need adjusting.

Figure 1. Image shows side-by-side slides with a VideoCast

Slides, agendas, and supplemental materials can be added to both live and on-demand VideoCasts. And because the images are converted to an Adobe SWF file, there is no helper program or plug-in required for users to install. Images look great and work seamlessly with the video program already installed on Windows and Mac computers. Animations and transitions however, are not supported. If slides are not available on the VideoCast page, go to the event web page to see if supplementary material is available.

Are all videos added to the archive and how quickly are they added?

All VideoCasts are posted in the past events section usually a few days after the event. New VideoCasts are added as quickly as possible, usually within a few days after the broadcast. All-day conferences take longer. On occasion the archive copies are made from backup tapes, which will delay this process. All VideoCasts are archived for on-demand playback. Video archives are not removed unless requested by the event coordinator.

How do I show VideoCasts "cinema style" in a conference room with a projector?

The Flash Player video size is 640x480 or 640x360. This format works best to stream content over the Internet. The best way to show NIH videos in a "cinema-session" would be to lower the computer's screen resolution to its lowest 640x480 or 800x600. To avoid degraded video, do not play in full screen. AV staff can contact the NIH IT Service Desk in advance to get the video link for an upcoming VideoCast so they can test the room 30 minutes prior to the actual start time.

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

Slides can be very 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.
