As you can see, the key to this is using the enable between feature of FFmpeg, and understanding the timestamps of when in your video you want to hide and show the different PNG overlays.Īgain, if you need to scale / crop the video to fit a certain size, you can do this all in one command using the scale and crop commands that FFmpeg offers. 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.
