  • Concat 2 video and add watermark first video ffmpeg

    31 août 2020, par cleanguy

    I have a Video #1, it has audio. Also I have a Video #2, with audio too. I would like to concat the #1 and #2 (or play #1 first, and then #2) and then add a watermark in #1 for the rest of the video, preserving audio timestamps.

    


    I used this command but the watermark appears on the #2 video ?

    


        ffmpeg -i Video1.mp4 -i Video2.mp4 -i watermark.png
   -filter_complex
       "[1][2]overlay=5:5[v2];
        [0][0:a][v2][1:a]concat=n=2:v=1:a=1"
   -c:v libx264 -crf 21 -c:a aac -b:a 384k -ar 48000 -movflags +faststart Out.mp4
