Learn about the source and target file formats to understand what happens during conversion.

Source Format

WMV Video

video/x-ms-wmv

WMV (Windows Media Video) is a proprietary video compression format developed by Microsoft, based on the Advanced Systems Format (ASF) container. It was designed for streaming and local playback on Windows platforms and includes built-in DRM support for content protection. WMV has largely been superseded by H.264/MP4 for most modern use cases.

Advantages

  • Good compression efficiency, especially at low bitrates
  • Native support in Windows Media Player and Windows ecosystem
  • Built-in DRM support for protected content distribution

Limitations

  • Proprietary format with poor cross-platform compatibility
  • Not supported on iOS, many Android players, or web browsers without plugins
  • Declining usage and relevance in modern video workflows

Common Uses

  • Legacy Windows video libraries and media collections
  • DRM-protected video content from older platforms
  • Windows-based screen recordings and presentations

Target Format

Flash Video

video/x-flv

FLV (Flash Video) is a container format that was used to deliver video content over the internet via Adobe Flash Player. It typically contains video encoded with Sorenson Spark or VP6 codecs and audio in MP3 or AAC format. FLV was once the dominant web video format but became obsolete after major browsers discontinued Flash Player support in 2020.

Advantages

  • Compact file sizes with acceptable streaming quality
  • Simple container structure that is quick to parse
  • Large existing archive of legacy web video content

Limitations

  • Obsolete format since Adobe Flash Player reached end-of-life in 2020
  • No modern browser supports FLV playback without third-party tools
  • Limited codec support compared to modern containers like MP4

Common Uses

  • Legacy web video archives and content migration
  • Converting old Flash-based video content to modern formats
  • Historical video content from early streaming platforms
