Once you start getting the hang of this, you can even animate your overlays! ffmpeg -i test.mp4 -i watermark.png \ filter_complex "pad=height=ih+40:color=#71cbf4,overlay=(main_w-overlay_w)/2:main_h-overlay_h" \ If we wanted to add branding or a watermark to the clip but not cover the existing video, we can use the pad filter to add some padding to our clip, and then position our watermark over the padding like so: ffmpeg -i test.mp4 -i watermark2.png \ filter_complex "overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2" test2.mp4 Using these variable we can position the watermark right in the center of the video like so: ffmpeg -i test.mp4 -i watermark.png \ Fortunately, there are variables you can use to better position your watermark depending on the size of the video. In some cases you might not know the exact dimensions of the videos you’ll be watermarking. We specify a specific position of the overlay in pixels – 10:10 puts the video 10 pixels from the top and 10 pixels from the right.
Once you have ffmpeg installed, adding a watermark is as easy as passing your existing source through an overlay filter like so: ffmpeg -i test.mp4 -i watermark.png -filter_complex "overlay=10:10" test1.mp4īasically, we’re passing in the original video, and an overlay image as inputs, then passing it through the filter, and saving the output as test1.mp4. Then you don’t have to worry about including and installing all the right dependencies and codecs you will be using.
The easiest way to install ffmpeg is to download a pre-built binary for your specific platform. FFMPEG filters provide a powerful way to programmatically enhance or alter videos, and it’s fairly simple to add a watermark to a video using the overlay filter.
