统一放大1.5倍，在进行平移
从左到右
ffmpeg -y -i 1.jpg -vf "zoompan='1.5':x='if(lte(on,-1),(iw-iw/zoom)/2,x+3)':y='if(lte(on,1),(ih-ih/zoom)/2,y)':d=150" 1.mp4
从右到左
ffmpeg -y -i 1.jpg -vf "zoompan='1.5':x='if(lte(on,1),(iw/zoom)/2,x-3)':y='if(lte(on,1),(ih-ih/zoom)/2,y)':d=150" 1.mp4
从上到下
ffmpeg -y -i 1.jpg -vf "zoompan='1.5':x='if(lte(on,1),(iw-iw/zoom)/2,x)':y='if(lte(on,-1),(ih-ih/zoom)/2,y+2)':d=150" 1.mp4
从下到上
ffmpeg -y -i 1.jpg -vf "zoompan='1.5':x='if(lte(on,1),(iw-iw/zoom)/2,x)':y='if(lte(on,1),(ih/zoom)/2,y-2)':d=150" 1.mp4
多张图片合成视频
ffmpeg -y -i 1.jpg -i 1.jpg -i 1.jpg -i 1.jpg -filter_complex "[0:v]zoompan='1.5':x='if(lte(on,-1),(iw-iw/zoom)/2,x+3)':y='if(lte(on,1),(ih-ih/zoom)/2,y)':d=150[v0];[1:v]zoompan='1.5':x='if(lte(on,1),(iw-iw/zoom)/2,x)':y='if(lte(on,-1),(ih-ih/zoom)/2,y+2)':d=150[v1];[2:v]zoompan='1.5':x='if(lte(on,1),(iw/zoom)/2,x-3)':y='if(lte(on,1),(ih-ih/zoom)/2,y)':d=150[v2];[3:v]zoompan='1.5':x='if(lte(on,1),(iw-iw/zoom)/2,x)':y='if(lte(on,1),(ih/zoom)/2,y-2)':d=150[v3];[v0][v1][v2][v3]concat=n=4:v=1:a=0,format=yuv420p[v]" -map "[v]" out.mp4
注意：其中[0:v]zoompan.......[v0]随图片数量递增，后面[v0][v1][v2][v3]concat=n=4跟着修改
