如何使用 ffmpeg 和 CMD 批量 zoompan .mp4

我需要一个 ffmpeg 批处理代码，它可以使用批处理代码将文件夹内的所有视频的分辨率编码和缩放到原始分辨率的 110％ 和 125％。

以下是我测试过不起作用的一些代码：

for %%a in ("*.*") do ffmpeg -i "%%a"  -vf scale=2*iw:-1, crop=iw/2:ih/2" "newfiles\%%~na.mp4"

pause
for %%a in ("*.*") do ffmpeg -i "%%a" -vf "zoompan=z='1+(1.4*in/300)':x='70*in/300':y='190*in/300':d=1"  "newfiles\%%~na.mp4"
for %%a in ("*.*") do ffmpeg -i "%%a" -vf "zoompan=z='1+(1.4*in/300"  "newfiles\%%~na.mp4"

error i getting
