WebM: An Open-Standard Choice

WebM, introduced by Google in 2010, is an open standard video format aimed at providing high-quality videos with less bandwidth. It’s a favorite among video content creators for several reasons:

  2. Quality: WebM offers good video quality, especially at lower bit rates, which is beneficial for streaming applications.
  3. Support: It has broad support among modern browsers and platforms, including YouTube, making it a convenient choice for online video sharing.

MP4: The Universally Accepted Codec

On the other hand, MP4, developed by the Moving Picture Experts Group (MPEG), is a digital multimedia format most commonly used for storing video and audio. Here’s why it stands out:

  1. Compatibility: MP4 boasts wide compatibility with a plethora of devices and platforms.
  2. Quality: It maintains a high level of video quality even at higher compression rates, making it a suitable choice for professional use.
  3. Support for Additional Data: MP4 can store additional data such as subtitles and still images, enhancing the user experience.
