is it possible to overlay an image on each frame of a video using FFMPEG

Question

I am trying to overlay 10 different images on a 10 second video. I am currently able to overlay one image over the entire time span of the video using FFMPEG. I want to be able to see a different image every sec on the video.

How can i achieve this if it is possible?

Regards, Reuben

You can, but it's going to be one long command. Are all images the same size and to be at the same position? — Gyan, Jan 08 '16 at 07:00
yes. It will be the same size as the video and so will be positioned at the start i.e. 0,0 — ReubenCH, Jan 20 '16 at 23:13

Yes the command should then look similar to this:

ffmpeg -y 
  -i foo.mp4 -i foo.jpg -i bar.jpg [...put more pics here...]
  -filter_complex "
      [0:v][1:v] overlay=25:25:enable='between(t,0,1)' [tmp];
      [tmp][2:v] overlay=25:25:enable='between(t,1,2)' [tmp]
      ...continue the same way...
  " 
bar.mp4

An easy method assuming you have an ordered sequence of images:

ffmpeg -i video.mp4 -pattern_type glob -framerate 1 -i "*.png" \
-filter_complex overlay output.mp4

The downside is that all input images need to be the same width, height, and pixel format: otherwise the overlaid frames may not display properly.

how do you mean `ordered sequence of images` ? – ReubenCH Jan 20 '16 at 23:18
Currently I have 10 images sequentially named from 1..10 but the command did not display the images in that order – ReubenCH Jan 20 '16 at 23:28
