Why Is It Necessary To Compress An MP4 File?

Compressing an MP4 file serves various functions. It reduces file size, allowing for more efficient storage and transmission. This is critical in today's digital landscape, where high file sizes can strain storage systems and consume a lot of bandwidth during transfers.

the need to compress mp4 video file

As compressed MP4 files can be swiftly uploaded and downloaded, they are easier to share over the Internet and email. Compression is especially important in streaming services, where it allows for seamless playback by lowering data transfer requirements. Users may minimize storage space, increase data transfer speeds, and improve overall streaming and sharing experiences by compressing MP4 files.

Types of Video Compression

TYPE 1: Lossy Compression

Lossy compression is a video compression method that reduces file size by permanently eliminating information deemed unimportant to human vision. It provides better compression ratios than lossless compression but at the expense of some video quality.

lossy video compression

Lossy algorithms assess the video data during the compression process and remove less obvious or redundant details, such as high-frequency noise or slight color fluctuations. This results in a decreased file size, which also means some visual information is lost. MPEG (including MPEG-4 and H.264) and AVI are popular lossy video compression formats. When efficient file size reduction is a priority, lossy compression is often utilized for online video streaming, video-sharing platforms, and multimedia apps.

TYPE 2: Lossless Compression

Lossless compression, as the name implies, is a video compression technology that keeps all of the video's original information without sacrificing quality. It accomplishes compression by locating and removing superfluous data inside the video clip, resulting in a smaller file size without sacrificing visual integrity.

lossless video compression

Lossless compression is frequently employed in circumstances when retaining the original video quality is critical, such as professional video editing, archive storage, or when the video must go through numerous editing or processing processes without degradation. At the same time, lossless compression produces better video quality but greater file sizes than lossy compression.
