MP4 and MP3 sound similar but are completely different from each other. Well, they are also similar to each other. If this statement confused you, then read further to figure out what these file types mean, what they contain and how they impact the storage of your on-the-go mobile devices.
Article Summary
- MP4 is a multimedia container that combines video, audio, metadata, subtitles, and thumbnails into one file. On the other hand, MP3 is the most popular and dedicated format for digital audio.
- MP3 is the king of storage efficiency whereas MP4s are optimized video files for streaming but they are still large because they hold visual data.
- MP4 and MP3 are both universally popular and leaders in their respective area. One is for video and the other is for audio.
What are MP4 Files?
Let’s start with the MP4 file container. MP4 files end in .mp4. This extension means that the file has been wrapped in an MP4 container. The container contains encoded video and audio, along with metadata if it exists. When they are all contained under a single file type or extension as an MP4, the file is called an MP4 file.
However, it should be understood that MP4 is a file container, and not a file format. This container wraps encoded video that is encoded in formats such as H.264 or H.265. These compression techniques allow video files to occupy less storage space than in their raw form. The audio that goes along with these encoded videos is usually in AAC format. Finally, metadata contains extra details such as chapter marks, bitrate, etc. The file might also be shipped with other features, such as subtitles and sometimes, still images which serve as the poster or thumbnail.
The most important parts of the entire MP4 file are usually the video and the audio tracks. The rest is extra information, which is nice to have. All these combined form the MP4 file.
Our application, Video to MP3 Music Converter, not only extracts the AAC tracks from the video but also compresses it into MP3 formats so that the high quality of the tracks are preserved while taking up a fraction of the disk space that the original raw audio can take.
What are MP3 Files?
You might have heard people using the term MP3. It is a widely popular term. Music players are called MP3 Players. Music files are called MP3 files. This name has been synonymous with audio and music for a long time now. It is because of how popular they are.
Well, what is the reason behind their popularity? Well, when storage was hard to come by, and audio files were big (Remember: WAV files?), MP3s file format was the knight in shining armor. It allowed us to store hundreds of songs on a single disk. That is because MP3s are compressed digital audio files that save the music quality of the original files. That means while taking up only a fraction of digital disk space compared to the raw audio, they sounded crisp and clear, maintaining the initial quality.
Due to their continuing popularity, they are still used and supported universally. Every music player will support this file format, no matter what. This format is the king of digital audio files. MP3 is the go-to format for music and audio. No matter how many new file formats are introduced, MP3 is still the leader in this space.
