In the era of content creation having plenty of videos stored on your PC locally requires a solution to save your drives from clogging. Knowing compression techniques, appropriate software, and how to not lose in quality during that is essential. In this guide, we discover how to reduce the video file size.

What is Video Compression?

Video compression is a way to make video files smaller. This involves encoding and knowing video formats that benefit the best of both worlds of compression and lossless quality. Compression works by removing unnecessary information from the video while retaining as much visual quality as possible. The difference in file size could be up to a 100:1 ratio comparing compressed vs uncompressed video data. This process allows for easier storage, transmission, and streaming of video content, as it requires less bandwidth and storage space compared to uncompressed video.

How to compress video size?

There are many ways to compress a video, from adjusting its properties to choosing an encoding method.

Video properties

Such properties as video Resolution and Framerate significantly impact video size. For instance, converting a video from 4K to 1080p or reducing the frame rate from 60fps to 30fps can decrease file size while still maintaining acceptable quality.

Besides, lowering the bitrate decreases the amount of data used per second of video, resulting in smaller file sizes. However, reducing the bitrate too much can lead to a noticeable loss of quality.

Encoding

When you are in video editing software, consider output formats for rendering such as H.264 (AVC) or H.265 (HEVC). These are up-to-date formats that offer better compression without sacrificing much quality. However, there are many software tools available that specialize in compressing video files. These tools often offer various compression settings and options to balance file size and video quality.

There is a lossless format that exists, but the filesize of such video will be 100 times bigger than compressed, so reducing video size without losing quality is virtually impossible. However, you can opt for a balanced approach by adjusting the compression setting which is available in most software allowing you to choose the compression ratio, manually adjust bitrate, framerate, and output resolution to achieve such a balance, or by simply choosing a preset for H.264 encoder for balanced outcome. Besides, if you have much time, you can also choose Two-Pass encoding which will take significantly more time but without sacrificing much quality your file will get compressed much better. On top of that, you can also opt for Variable Bitrate (VBR) which allocates more bits to complex scenes and fewer bits to simpler ones, resulting in better quality at a given file size compared to constant bitrate (CBR) encoding.

How To Reduce Video Sizes on Android

  1. Download a video compression app from the Google Play Store, such as Video Compressor or VidCompact.
  2. Open the app and select the video you want to compress from your phone's gallery.
  3. Choose the compression settings, typically including resolution, bitrate, and format.
  4. Preview the compressed video to ensure quality meets your requirements.
  5. Once satisfied, save or export the compressed video.
  6. Optionally, delete the original video to free up space on your device.
  7. Share the compressed video via email, messaging apps, or social media directly from the app if needed.
