  3. Utilize Codecs and Formats Efficiently: Different codecs and formats have varying compression efficiencies. Explore different options and choose the most efficient codec and format combination for your specific needs.
  4. Consider Batch Compression for Multiple Files: If you have multiple MP4 video files to compress, utilize batch compression features available in some software. This will save you time and effort by compressing multiple files simultaneously.
