  • FFMPEG : Merge multi video and audio, loop first video until audio end

    8 février 2024, par Khuê Bùi

    I'm trying to merge multi video and an audio file but I have tried looping the video many times but without success, it plays all 3 videos and stops at the 3rd video until the end of the audio.

    


    ffmpeg -y -i "video\0.mp4" -i "video\1.mp4" -i "video\2.mp4" -i audio.m4a -filter_complex "[1:v]xfade=transition=wipeleft:duration=1:offset=9[vfade1];[vfade1][2:v]xfade=transition=wipeleft:duration=1:offset=18[v]" -map "[v]" -map 3:a -c:v libx264 -r 30 -pix_fmt yuv420p -c:a aac -strict experimental ./out_fade1.mp4


    


    Please help me fix the code so that it plays the video 0.mp4 -> 1.mp4 -> 2.mp4. If the audio is still there, then return to 0.mp4 and continue like that until the end of the audio.

    19 février 2021, par cantoe

    Use ffmpeg to add video watermark.
But the second video added does not move, only static images can be seen.
Does anyone know what's going on ?
Can you help me ?

  • FFmpeg - add .mov video overlay looping on top of input video till the end

    11 septembre 2017, par Joao Vitor

    So i have 2 files.

    C:\video_resized.mp4
    

    
C:\videoOverlay.mov

    "C :\videoOverlay.mov" needs to go on top of "C :\video_resized.mp4" and at the same time it needs to loop until the end of "C :\video_resized.mp4"

    I tried to use

    "C:\ffmpeg\bin\ffmpeg.exe" -i "C:\video_resized.mp4" -i "C:\videoOverlay.mov" -filter_complex "overlay=0:0" "C:\video_watermarked.mp4"

    That works fine for adding the overlay, but i have no idea on how to have the overlay looping until the end of the first video.
