Estoy tratando de superponer varios videos en un video base, los videos se superponen pero el audio del video base primario se pierde. Además, si quiero agregar más videos, ¿qué pasos debo seguir?
El siguiente es mi comando:
ffmpeg -i master_video.mp4 -i comment_1_offset.mp4 -i comment_2_offset.mp4 -filter_complex "[0:v][1:v]overlay=900:450:enable='between(t\,06,12)'[bg];[bg][2:v]overlay=0:0:enable='between(t\,8,15)'[v]; [1:a][2:a]amerge=inputs=2[a]" -map "[v]" -map "[a]" -ac 2 final_comments.mp4
OUTPUT:
