How To Compress a Video?

  • Click on the “Compress Video” button to start compression
  • When the status change to “Done” click the “Download Video” button

How does video compression work?

Video compression is based on the understanding that information between consecutive frames in a video changes very slowly.

So, most video compression schemes have the following components:

  • An Intra-frame coder (like JPEG) where some key frames are coded on their own
  • A Predictor; Areas of a current frame are predicted based on past or future frames – and a prediction error (or residual) is computed; This is called inter-frame prediction.
  • A transform encoder – Changes pixels (in intra-mode) or residuals (in inter-prediction mode) to a domain that is easier to compress (say, the DCT)
  •  A quantizer – This is where the actual compression is performed. Information that is considered perceptually irrelevant is removed.

Advanced Methods of Video Compression

To compress a video, there are two primary strategies. The video can be optimised or you can resize the video to a smaller size. They give 3 settings related to both techniques. The explanation here is:

1. By Video Quality

CRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. To do that, it uses different compression levels on different frames. For H264 encoder, possible CRF values range from 0 to 51. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). The default is set at 23.

Preset: Presets refers to the video compression speed. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level. If you prefer lower file size over encoding time, choose a slower preset.

2. As a Percentage of the Original Size (Default)

This method allows you to set a target file size for your video as a percentage of the original size. For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less.

The pros of this method is, you can achieve a certain target size. The downside is you don’t know how the target size will affect video quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. Increase the target size if you need better quality.

This is the default video compression method used.

3: Make Video Size Smaller (Re-Size)

Choosing a smaller video resolution (dimensions) can also save file size. For example, if you have a 4K (4320p) video but your target device is 1080p, you can downsize the video to fit 1080p and save file size. To choose this option, choose “Re-size video” from “Advanced Settings” above.
