Video Compression

Published Date: 14 December 2022

What is Video compression?

Video compression is a technique to reduce the size of video files, alter bit rates, or change their format to facilitate transmission over the internet.

Video compression increases the compatibility of video formats (size, such as MP4, WMV, MOV, M4V, etc.) across different platforms and operating systems. It can either be lossless (converting video from one digital format to another) or lossy (reducing file size and storage space, which may lead to data loss or minor quality deterioration.)

Benefits of Video Compression

  • Video compression ensures buffer-free viewing and improves user experience
  • Video compressors eliminate unwanted data (audio or repeated frames) from videos and make files smaller for seamless transmission over the internet.
  • It is the easiest way to boost compatibility and reach without affecting the overall visual quality.
  • With algorithms like H.264/AVC or H.265/HEVC, video can be compressed by up to 1,000 times.
  • It saves operational costs.

Applications of Video Compression

Video Compression is employed in a range of industries and sectors:

  • Edtech: It allows eLearning platforms to offer flexible access to educational material from anywhere, at any time—thereby revolutionizing the Edtech sector. It improves device compatibility, streamlines the streaming workflow, and cuts operational costs.
  • OTT platforms: Video compression boosts the reach of streaming platforms and drives maximum ROI. With technologies like ABR eliminating buffering and latency issues, OTT platforms can deliver high-quality viewing experiences and retain audiences.
  • Social media: Video compression enhances the shareability of video over the internet, helping content creators deliver their content across social media channels.

Video Quality

In simple terms, video quality is the characteristic of a video that determines how clear, crisp, and detailed the video transmitted to the viewer is.

Video Watermark

A video watermark is a digital copyright tool used to identify the video's copyright owner or prevent illegal distribution.


1:1 is a commonly used aspect ratio in videography. It produces videos that are a perfect square; the width and height of the video image are the same.
