  • ffmpeg - merge 3 videos and scale output file to 720p [duplicate]

    25 septembre 2021, par Paker Jack

    I have 3 videos : intro.mp4 main-video.mp4 outro.mp4
The main-video.mp4 is vertical and has size bigger than 720p sometime.

    


    So i want to merge 3 videos together and resize the output video to 1280x720
I know how to merge videos and scaling but i don't know how to combine them.

  • Scale image overlay over the time with ffmpeg

    27 avril, par Nazarii Kahaniak

    I have an overlay image and background video. I want to make the overlay 3 times bigger when 10 seconds of video pass, the scaling animation should take 1 second. Is it possible to do something like this with ffmpeg ?
