  • how to add overlay at the end of video without knowing time duration of video file - ffmpeg

    13 décembre 2019, par Luka mikic

    I have a bunch of video files to which I add animated overlay at the beginning of video, but I would like to add it again at the end of it t-13 seconds. This is my bash script :

    do
    
   ffmpeg -i "${f}" -i /app/logo/lower.mov -i /app/logo/logo.png -filter_complex \
    
      "[0:v]scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:x=(1280-iw)/2:y=(720-ih)/2:color=black[bg0]; \
    
      [bg0][1:v]overlay=10:10[bg1]; \
    
      [bg1][2:v]overlay=10:10,drawtext=fontfile=/app/logo/Courier Prime.ttf:text=$(basename "${f}" | cut -f 1 -d '.'): \
    
      fontcolor=white:fontsize=25:x=256:y=h-th-130:alpha=1:enable='between(t,2,15)'" \
    
      -c:v libx264 -crf 21 -preset ultrafast "${f%.*}.mp4" -y
    
done

    Is there any way to do this ? I know how to extract the duration with FFProbe, but do not know how to add duration dynamically to a variable and then apply it to code I have.

  • How do i add multiple sound effects (mp3) to a video (mp4) at any given time in the video ? [closed]

    25 octobre 2023, par StudentProgrammer

    I am trying to automate my editing process. I have a video.mp4 with a given length, a folder with different sound-effects.mp3 and a list of timestamps = (t1, t2, t3...). I would like to be able to insert any sound-effect at any given time in the video. Furthermore a sound may last multiple seconds and overlap another sound. I've tried to visualize the concept with images.

Preferably this would be done in Python. However, I would be extremely happy if anyone took their time to help me out using any means of programming required.

    


    I have tried using Moviepy without much success as I am only able to add sound to the start of the video. Perhaps ffmpeg is the way to go.
