FFMpeg - Overlay tidak ditampilkan saat enable = antara parameter ditambahkan
Aug 20 2020
Saya menggunakan perintah di bawah ini untuk menambahkan efek transisi antara video menggunakan overlay sehingga ketika satu video akan selesai, overlay akan terlihat. Sebelum menampilkan overlay, saya harus menambahkan padding dan menggabungkan video membuat satu video tunggal dan kemudian menampilkan overlay .:
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
Tetapi perintah di atas tidak menampilkan video overlay apa pun. Jika saya menghapus enable = between (t, start, end) dari parameter overlay, semua overlay akan ditampilkan saat video mulai. Saya sangat pemula dalam mengedit video dan FFMpeg. Adakah yang bisa membimbing saya apa yang saya lakukan salah di sini?

Filter overlay menyinkronkan kedua input dengan stempel waktu, sehingga X kedua dari video overlay dicetak di atas X kedua dari video utama. Jadi, dengan alasan overlay=0:0:enable='between(t\,7\,9)', ffmpeg akan dimulai dengan tujuan untuk overlay frame dengan timestamp 7.00 di atas video utama dengan timestamp 7.00. Jika video overlay tidak terlalu lama, tidak akan ada efek apa pun.
Stempel waktu video overlay perlu dimodifikasi untuk membuat sinkronisasi yang diperlukan.
[3:v]colorkey=0x00d800:0.1,scale=w=1080:h=1920,setpts=PTS-STARTPTS+7/TB[tr0];
Setpts menggeser aliran transisi pertama untuk memulai dengan stempel waktu 7. Ini sekarang dapat ditumpangkan enable='between(t\,7\,9)'.
