Reasons Why MP4 is the Most Preferred Format

  • Interoperability: MP4 is an open standard supported by a wide range of software applications and devices, making it an ideal format for interoperability between different platforms. This allows for greater video production and distribution flexibility and ensures that content can be easily shared and played across other devices and software applications.
  • Multimedia Features: MP4 supports various multimedia features such as subtitles, metadata, and chapters. These features enhance the overall user experience by providing additional information and navigation options.
  • Efficient Storage and Transmission: MP4 files are relatively smaller in size compared to other formats, making them efficient for storage and transmission. This is particularly beneficial for mobile devices with limited storage capacity and for faster uploading and downloading of videos.
