This would spread the overlays evenly out across a 9 second video. This is more challenging as it requires knowing the times in the video where you want the overlay to be visible.Īssuming that you have a video named video.mp4 and 3 overlays named 1.png 2.png 3.png - and that they video and overlays are of the same dimensions, the FFmpeg command to overlay the PNGs on the video is as follows: ffmpeg -y -i video.mp4 -i 1.png -i 2.png -i 3.png -filter_complex overlay=enable='between(t,0,3)':x=0:y=0 overlay=enable='between(t,3,6)':x=0:y=0 overlay=enable='between(t,6,9)':x=0:y=0 -map -map 0:a? new.mp4 A common use case for this would be to add hard-coded subtitles onto a video, that need to display at specific points in the video. Overlaying a sequence of multiple PNGs onto a video is also possible. If your video is of a different size to the overlay, or you need to standardize the size of the video before applying the overlay, you will need to use the scale and crop commands that FFmpeg offers. You may want to overlay a static PNG to add a watermark or some kind of frame around a video.Īssuming that you have a video named video.mp4 and an overlay named overlay.png - and that the video and overlays are of the same dimensions, the FFmpeg command to overlay the PNG on the video is as follows: ffmpeg -y -i video.mp4 -i overlay.png -filter_complex overlay=x=0:y=0 -map -map 0:a? test.mp4 The following examples all use FFmpeg defaults for codecs and framerates. ExamplesĪ video with a sequenece of PNG overlays:ĭisclaimer: in the following examples I will not be setting any video / audio codec flags since you will likely want to choose your own.

Here's how to add PNG overlays onto a video using FFmpeg. FFmpeg is an incredibly powerful tool you can use for manipulating video.
