Further functionality can be found here: Or if we wanted to centre the overlay image on the video we can do the following:įfmpeg -i video.mp4 -i watermark.png -filter_complex 'overlay=x=((main_w-overlay_w)/2):y=((main_h-overlay_h)/2)' output.mp4Īs you can see, FFmpeg is a very powerful tool with the overlay filter being just a very small demonstration of what can be achieved. Using these variable we can position the watermark to the bottom-right of the video with a 20px padding like so:įfmpeg -i video.mp4 -i watermark.png -filter_complex 'overlay=x=(main_w-overlay_w-20):y=(main_h-overlay_h-20)' output.mp4 There are variables which we can use to better position your watermark. Positioning the overlay imageīy default, overlay filter positioning is from the top-left. The overlay=10:10 specifies the positioning of the overlay image in pixels – 10:10 puts the video 10px from the top and 10px from the left. This command passes the original video ( video.mp4), and an overlay image ( watermark.png) as inputs, through the overlay filter, and saves the output as output.mp4. Once FFmpeg has been installed, adding a watermark is just a simple task of passing your existing video source through an overlay filter via the command prompt:įfmpeg -i video.mp4 -i watermark.png -filter_complex 'overlay=10:10' output.mp4 Manually edit the Environment Path Variable.Open a command prompt with administrator rights.īe sure to alter the command so that the path reflects the folder path to ffmpegin.Finally, we just need to add the bin folder – which contains ffmpeg.exe – to our system path which will allow us to run the commands easily.Extract the contents from the downloaded file to the newly created C:fmpeg folder.Select the hard drive where Windows is installed (typically C:) and create a new folder named “ ffmpeg” at the base of this drive (where you see folders such as Windows and Program Files).Just download and install a pre-built binary for your operating system. It supports the most obscure ancient formats up to the cutting edge. FFmpeg filters are a powerful tool that can do almost anything you can imagine with multimedia files – changing an AV file’s format or quality, extracting audio, adding watermarks, and so much more.įFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created.
