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. All other fields are optional.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. To upload the image directly, please send a POST request using multipart/form-data as the content-type and specify the file under the file key. ​​ Creating a Watermark profile ​​ Use Case 1: Upload a local image file directly Note that center will ignore the padding parameter. Valid positions are: upperRight, upperLeft, lowerLeft, lowerRight, and center. Position string (enum) default: “upperRight” The algorithm will make sure that the watermark will look about the same size across videos with different dimensions. 0.0 means no scaling (use the size of the watermark as-is), and 1.0 fills the entire video. This parameter will adapt to horizontal and vertical videos automatically. The size of the watermark relative to the overall size of the video. Stream will make sure that the watermark will be at about the same position across videos with different dimensions. 0.0 means no padding, and 1.0 means padded full video width or length.

Whitespace between the adjacent edges (determined by position) of the video and the watermark. Note that if the watermark is already semi-transparent, setting this to 1.0 will not make it completely opaque. 0.0 means completely transparent, and 1.0 means completely opaque.
