Video cropping is an important technique to optimize videos for different screens. In this part, detailed steps will show you how to use FFmpeg crop video without losing quality:

  • Step 1: Download FFmpeg to your system through the code given to developers. If it's unavailable this way, you can install it from the local package manager. Then, get a sample video you want to crop through FFmpeg commands.

  • Step 2: Now, extract the height and width of the sample video through the code below. There, ffprobe refers to a tool that extracts information from media streams. The -v error is used to set the verbosity level of errors only, and -select_streams can select specific streams for analysis.

    Moreover, -Show_entries are used to specify information to display, such as height, width, or resolution. Lastly, -of compact set output printing format, and the other is the video file's name.

  • Step 3: Use the command template given ahead for basic cropping and learn about different options. As the ffmpeg with -i option shows the input video file, the output file is output.mp4 at the end. The actual video processing happens with the command -filter:v “crop=out_w:out_h:x:y”. In this case, -filter:v specifies the video filter, and the crop filter specifies four parameters.

    Among them, out_w is the desired width, and out_h is the desired height of the video output. Plus, x refers to a horizontal position, and y refers to the vertical position of the input video.

  • Step 4: Apply the above basic cropping on your sample video through the given command and keep the central position of the videos. This command will create a video file named cropped_video.mp4 from the original video. It will start from 320(x) and 180(y) coordinates with 640x360 pixels resolution in a cropped video.

  • Step 5: After learning the basic cropping, crop the central part from the video without specifying x and y coordinates. Using this command, you can crop the central square with 600 pixels from the input video.

    Now, let’s specify the output width and height using the expressions below. This command will crop 2/3 of the size of the input video and save the crop areas with cropped_video3.mp4.
