About FLV

Flash Video (FLV) files contain video bit streams. It is the required video compression format for Flash Player 6 and 7. The Flash Video FLV file format supports two versions of a so-called 'screenshare' (Screen video) codec which is an encoding format designed for screencasts. Both these formats are bitmap tile based.

Pros Cons
  • Installed on a higher percentage of end user computers than any other video format. Flash still enjoys the best overall support.
  • Flash files look the same and work equally well on PCs, Macs, and Linux.
  • Consistent operation, so it functions the same way for all end users.
  • Provides interactive content and other advanced features.
  • The second version can only be played in Flash Player 8 and newer.
  • Not all end users have the latest version so they may not be able to use the latest Flash video codec.
  • Quite complex and time-consuming to create a video.

About WMV

WMV files are a type of video file (usually containing audio) from Microsoft.

Pros Cons
  • These files can be played on a variety of video players on both Mac and PC machines.

  • The digital rights management system is sometimes attached to WMV files.
  • The inability to restore licenses for WMV files in the Windows Media Player 11
  • The fact that Microsoft Zune does not support the standard Windows Media DRM system, makes protected WMV files unplayable.
