You wish to place a video on a webpage such that it will be playable directly in the browser. Which is the most suitable file type to use?

  • .rm (Realmedia)
  • .webm (WebM)
  • .flv (Adobe Flash)
  • .mov (Quicktime) 

 

EXPLANATION

Most modern browsers can play the .webm file format directly, without the need for any special plugins. Many can also play .mp4 (MPEG 4) or Ogg files directly, so that could also be an option. However, support for these is not as universal.
WebM is actually a subformat of the Matroska container, with video in VP8 or VP9  encoding, and audio in Vorbis. or Opus. VP8 and Vorbis will give the widest compatibility.
The older standards of Realmedia, Quicktime, and Flash Video required special plugins to be installed, and in some cases these plugins suffered numerous security vulnerabilities. Thus, their use is to be discouraged. 

Support for WebM on legacy hardware is good, provided that a modern browser is installed. MPEG 4 is less likely to work in browsers on older operating systems, although the free VLC Media Player can play the downloaded files if streaming is not possible.
