私は写真とアニメーションGIFボーダーオーバーレイとオーディオトラックからビデオを作成するために使用するこのffmpegコマンドを持っています。ffmpegオーバーレイ画像と低い透明度
ffmpeg -framerate 15 -loop 1 -i photo.jpg -ignore_loop 0 -i overlay.gif -filter_complex "scale=(iw*sar)*max(600/(iw*sar)\,750/ih):ih*max(600/(iw*sar)\,750/ih), crop=600:750, overlay" -i audio.wav -c:v libx264 -c:a aac -b:a 192k -shortest output.mp4
私が望むのは、オーバーレイ画像の不透明度を下げることです。
私は多くのスレッドをチェックしましたが、このようなものを既存のフィルタと組み合わせる方法を理解できません。
-filter_complex "blend=all_mode='overlay':all_opacity=0.7"
ここに私のテストの1の完全なffmpegの出力です：
ffmpeg -framerate 15 -loop 1 -i photo.jpg -ignore_loop 0 -i overlay.gif -filter_complex "scale=(iw*sar)*max(600/(iw*sar)\,750/ih):ih*max(600/(iw*sar)\,750/ih), crop=600:750, blend=all_mode='overlay':all_opacity=0.7" -i audio.wav -c:v libx264 -c:a aac -b:a 192k -shortest output.mp4
