Question

Hey guys I am trying to overlay an image at the cntre of a video in ffmpeg like this:

ffmpeg -i video.mp4 -i image.png -filter_complex "[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" -pix_fmt yuv420p -c:a copy output.mp4

But the image get placed on the top-left side of the video. How can I adjust the image to the centre?

Use

ffmpeg -i video.mp4 -i image.png -filter_complex "[0:v][1:v] overlay=(W-w)/2:(H-h)/2:enable='between(t,0,20)'" -pix_fmt yuv420p -c:a copy output.mp4

W amd H are the base video's dimensions. And w and h the overlay video's.

Hey, thanks, @Mulvya. Can you tell me how can I position the image on the video? – Pradhvan Bisht Nov 08 '16 at 10:57
The first two arguments in the overlay are the x and y coordinates with respect to the top left of the Base video. – Gyan Nov 08 '16 at 12:19

It's already there in the answer : `enable='between(t,0,20)` – Gyan Jun 02 '17 at 08:54
