Sound
& music score
The Sound and Music Score, or Soundtrack, is
a hugely important part of a successful video. The use of audio such as music,
sound effects and vocal dialogue all play a big part in telling the story.
Altering the type of sound used, particularly the choice of music or background
ambience, has a big effect on the mood of the video.

Web
streaming is the process of delivering multimedia — usually audio or video —
over the World Wide Web.
Streaming media does not need to be downloaded
and stored on a local computer. In fact, most of the time it cannot be saved to
a computer. As media is streamed, it is stored in a temporary storage space
called a buffer so that it can be viewed or listened to before the
entire file has loaded. Generally, a few seconds of media are buffered before
the file begins to play. Interference or a slow Internet connection can cause
playback to stall if new data can't be loaded into the buffer quickly enough.
-Windows Media Video (WMV)
-Apple Quicktime
-Realmedia (RM)
-MPEG-4
-Flash video (FLV/F4V)
Live streaming, delivering live over the
Internet, involves a camera for the media, an encoder to digitize the content,
a media publisher, and a content delivery
network to distribute and deliver the content.
