FFMPEG- Is it possible to overlay multiple images over a video at specified intervals?

10,601

Basic method is

ffmpeg -i video -i image1 -i image2 -i image3
 -filter_complex
    "[0][1]overlay=x=X:y=Y:enable='between(t,23,27)'[v1];
     [v1][2]overlay=x=X:y=Y:enable='between(t,44,61)'[v2];
     [v2][3]overlay=x=X:y=Y:enable='gt(t,112)'[v3]"
-map "[v3]" -map 0:a  out.mp4

The last image will be overlaid from t=112 seconds till end of video.

I want to overlay multiple images (Say 5) in a 120 second video at specified intervals , like, between 3-7 seconds overlay image 1. Is is it possible without splitting the video in multiple parts?

Thanks. It is working. But there is a visible difference in quality of the video generated as output.

Insert -crf 18 after the filter the complex. I assume you have libx264 in your ffmpeg build.

if i have a single image to be overlapped at multiple intervals, will i have to specify it in input multiple times?

No. Just reuse the same input pad e.g. [1].

Hi. In this command, can we specify the input images to be overlayed in a text file? The final command getting generated is very very long. I have already put the complex filters in a script.

It should be possible.

Thanks. How to specify input pad in this case? Like i have 3 image path in a text file, how can we tell that overlay 1st image for these much seconds, 2nd for these seconds?

I am also doing the same, however my need is to be millisecond precise. There i find it hard to see precise timing in image overlay. Do you have any suggestion for me? Please see my post stackoverflow.com/questions/45818266/…

@Mulvya by using this command all images will appear 23 to 27(image1) after 27 second image1 disable and image2(44 to 61) enable and then disable at 61 sec and so on am i right? but in my case after showing first image other images can not visible
