ffmpeg - video processing - create transition with blank video
15 septembre 2015, par armoucarffmpeg newbie here struggling to do something that apparently should be easy.
I want to concatenate three videos, being one of them just a blank video two seconds transition.
First I generate the blank video with :
ffmpeg -f lavfi -i color=c=black:s=320x240:d=0.5 silent.mp4
After I try to concat it with two other videos I have :
ffmpeg -i video-a.mp4 -i 2-seconds-silent-video.mp4 -i video-b.mp4 -y -filter_complex concat=n=3:v=1:a=1 result.mp4
