FFmpeg is a free and open-source tool to convert and edit videos. It has many excellent functions, but few people will use it due to its difficulty in operating. This post will detail the steps from installation to how to use FFmpeg to trim/crop/resize videos.

Step 1.Take Windows as an example. Search for FFmpeg on your browser and download the software based on your system.

Choose Path and Install FFMPEG

Step 3.After installation, open a "command" prompt window, type "ffmpeg", and press Enter key to launch it. Now you can trim/crop/resize videos with FFmpeg.


Step 4.If you want to trim a video using FFmpeg, copy and paste the following command into FFmpeg

"ffmpeg -ss 00:01:00 -i input.mp4 -to 00:02:00 -c copy output.mp4"

This means starting at 00:01 and ending the video at 00:02. The output format is MP4. "−ss" is the start of the trim in the videos, and -to is the end of the trim in the videos. You can adjust the time freely according to your needs.

Step 5.Crop and resize the video with FFmpeg. You should type the command line as follows:

ffmpeg −i input.mp4 −filter:v 'crop=w:h:x:y' output.mp4

w is the width of the output rectangle in pixels, while h is the height of the output rectangle in pixels. x and y mean the top left corner of the output rectangle, also in pixels. For example, ffmpeg −i input.mp4 −filter:v 'crop=100:100:0:0' output.mp4 means you want to crop the 100 × 100 pixels from the top right corner of input.mp4 file and save the cropped video named output.mp4.


You should replace the input.mp4 with your video file name and extension while replacing output.mp4 with the output video file name and format.
