  • FFMPEG Overlay one video on top of another video at specific location

    11 août 2018, par Ewan Sou

    I have two videos (in mp4 format). I would like to put one video on top of the other video

    • Both videos have the same duration
    • The bottom video is of resolution 640px by 640px
    • The top video is also of resolution 640px by 640px

    I need to scale down the top video resolution to 580px by 580px. Then I need to position it in a specific location on top of the bottom video.

    I tried the below quote

    ffmpeg -i bottom.mp4 -i top.mp4 -filter_complex "[0:0][1:0]overlay=enable='between(t\,0,50)'[out]" -shortest -map [out] -map 0:1 -pix_fmt yuv420p -c:a copy -dn -c:v libx264 -crf 18 output.mp4

    It does allow me to put the top video on top of the bottom video I think. But the top video was not scaled down in size. Also, this top video is by default on the top left corner of the bottom video.

    In additional, somehow, the very first frame will not show the top video at all. Only at around the 0.5sec will the top video appear. Is there any way to make it such that the top video is showing at the very first frame too ?

    Thank you all in advance !

  • Python/ FFMpeg : how can I in python have ffmpeg extract image from video, edit images, then create new video with sync'd audio from source video ?

    24 avril 2021, par Chris Walters

    I have a video input.mp4. I want to extract frames from input.mp4, modify them, and then recreate a new video with the same properties as the original, including sync'd audio. How can I do this in Python ?

    


    Thanks !
