This not only facilitates the inclusion of multimedia in a web page but also improves compatibility and performance across different devices and browsers.

Considerations on Formats and Compatibility

Not all browsers support all audio and video formats in the same way. It is advisable to provide multiple formats to ensure compatibility across all browsers.

Common Audio Formats

  • MP3: Highly compatible and good quality.
  • WAV: High quality but large file sizes.
  • Ogg: Free format and good quality.

Common Video Formats

  • MP4: Highly compatible and good quality.
  • WebM: Good balance between quality and file size.
  • Ogg: Free format and good quality.

Conclusion

Native support for audio and video in HTML5 makes adding multimedia content simpler and more efficient. Using the new <audio> and <video> elements, along with JavaScript for greater control, enriched and accessible multimedia experiences can be created for all users.
