How to Compress Video using FFmpeg to Reduce 90% Size without Quality Loss

Introduction

In this article, we will explore how to use FFmpeg, a powerful, free command-line tool, to compress video files significantly—up to 90%—while maintaining quality. This process is especially useful if you need to save storage space or make videos web-friendly without resorting to paid software solutions.

Step-by-step Guide to Compress Videos with FFmpeg on Windows

Download FFmpeg: Begin by downloading FFmpeg from the official link provided in the video description. Make sure to select the appropriate version for your Windows operating system.
Add FFmpeg to Your System Path: To use FFmpeg easily from the command line, you'll need to add its installation path to your system environment variables. Here’s how:
- Save the downloaded FFmpeg folder to a location of your choice.
- Copy the path to the bin folder, where the ffmpeg.exe file is located.
- Search for “environment” in the Windows start menu and open "Environment Variables."
- In the “User Variables” section, find the Path variable and click "Edit."
- Paste the path to the bin folder and save your changes before exiting the window.
Navigate to Your Video File: Open the folder containing the video file you want to compress. Right-click in the empty space of the folder and select "Open Terminal" (or "Open Command Prompt").
Run the Compression Command: In the terminal, type the FFmpeg command to compress your video. You will need to specify the input file name (the name of your original video) and hit enter.

Here's a basic example of the command format:
```
ffmpeg -i inputvideo.mp4 -vcodec libx265 -crf 28 outputvideo.mp4
```
Replace inputvideo.mp4 with the name of your source video.
Wait for Compression to Complete: Depending on the size of your original video, the process may take some time. It is recommended to leave your PC idle during this period to ensure maximum performance.
Check the Results: Once the compression is complete, check the size of the newly created video file. You should notice a drastic reduction—often more than 90%—while maintaining impressive quality. You can also compare the properties of the original and compressed videos, and you’ll find that the resolution remains the same, with only the bitrate differing.

Conclusion

Using FFmpeg to compress your videos is a simple yet effective method to save space without sacrificing quality. With this guide, you can easily compress videos on your PC at no cost, making it a valuable tool for anyone working with video content.
