我有两个视频滤镜，只要在单独的批处理文件中使用它们就可以工作，但我找不到将它们组合起来的方法。第一个滤镜调整 JPG 图像的大小，然后创建包含淡入淡出过渡的幻灯片：
-reinit_filter 0 -r .3 -f concat -safe 0 -i concat_image_list_JPG.txt -c:v libx264 -crf 25 -pix_fmt yuv420p -vf zoompan=d=(6+2)/2:s=1920x1080:fps=1/2,framerate=25:interp_start=0:interp_end=255:scene=100 -r 25 "Slideshow 1080.mkv"
问题是，没有 16:9 AR 的图像将被垂直或水平拉伸以填充框架。另一方面，以下命令创建幻灯片没有淡入淡出过渡但是它通过对图像进行信箱/柱箱处理保留了所有图像的正确纵横比：
-r .3 -f concat -safe 0 -i concat_image_list_JPG.txt -c:v libx264 -crf 25 -pix_fmt yuv420p -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:-1:-1:color=black" -r 25 "Slideshow 1080.mkv"
我如何才能将两个命令/过滤器组合到一个批处理命令中，以实现所有图像的正确 AR 并使其交叉淡入淡出？我尝试将它们放在彼此后面并用逗号分隔，但没有成功。
这是运行答案 1 中的命令时的日志：
