FFMpeg-enable = between 매개 변수가 추가 된 경우 오버레이가 표시되지 않음
Aug 20 2020
아래 명령을 사용하여 오버레이를 사용하여 비디오간에 전환 효과를 추가하여 하나의 비디오가 끝나려고 할 때 오버레이가 표시되도록합니다. 오버레이를 표시하기 전에 패딩을 추가하고 비디오를 연결하여 하나의 단일 비디오를 만든 다음 오버레이를 표시해야합니다. :
ffmpeg
-i input1.mp4
-i input2.mp4
-i input3.mp4
-i transition1.mp4
-i transition2.mp4
-filter_complex
"[0:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video0];
[1:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video1];
[2:v]pad=width=1080:height=1920:x=(1080-iw)*0.5:y=(1920-ih)*0.5:color=black[video2];
[video0][video1][video2]concat=n=3:v=1:a=0[outv];
[3:v]colorkey=0x00d800:0.1[t0];
[t0]scale=w=1080:h=1920[tr0];
[4:v]colorkey=0x00d800:0.1[t1];
[t1]scale=w=1080:h=1920[tr1];
[outv][tr0]overlay=0:0:enable='between(t\,7\,9)'[out0];
[out0][tr1]overlay=0:0:enable='between(t\,12\,15)'[out1];
[0:a][1:a][2:a]concat=n=3:v=0:a=1[audio]"
-vsync 0 -c:v libx264 -pix_fmt yuv420p -map [out1] -map [audio] -preset ultrafast output.mp4
그러나 위의 명령은 오버레이 비디오를 표시하지 않습니다. 오버레이 매개 변수에서 enable = between (t, start, end)를 제거하면 모든 오버레이가 비디오 시작시 표시됩니다. 저는 비디오 편집과 FFMpeg에 매우 초보자입니다. 아무도 내가 여기서 뭘 잘못하고 있는지 안내해 줄 수 있습니까?

오버레이 필터는 두 입력을 타임 스탬프별로 동기화하므로 오버레이 비디오의 두 번째 X가 기본 비디오의 두 번째 X 위에 인쇄됩니다. 따라서 overlay=0:0:enable='between(t\,7\,9)'인수가이면 ffmpeg는 타임 스탬프 7.00으로 기본 비디오 위에 타임 스탬프 7.00이있는 오버레이 프레임을 오버레이하는 것을 목표로 시작합니다. 오버레이 비디오가 그렇게 길지 않으면 효과가 없습니다.
필요한 동기화를 생성하려면 오버레이 비디오 타임 스탬프를 수정해야합니다.
[3:v]colorkey=0x00d800:0.1,scale=w=1080:h=1920,setpts=PTS-STARTPTS+7/TB[tr0];
setpts는 첫 번째 전환 스트림을 타임 스탬프 7로 시작하도록 이동합니다 enable='between(t\,7\,9)'. 이제 .
