我正在尝试通过放大图像（.mov输出，mjpeg编解码器）来制作一个简单的6秒视频剪辑。当我将输出设置为1920x1080时，我可以使用此命令：
ffmpeg -y -r 25 -nostdin -loop 1 -i input.jpg -vf "zoompan=z='min(zoom+0.0015,1.5)':d=700:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)'" -c:v mjpeg -qscale:v 1 -t 6 -s "1920x1080" "test/output.mov"
但是当我将输出设置为4K（3840x2160）时它不再起作用：命令挂起，被杀死或产生损坏的输出。
我的input.jpg分辨率为4240x2832。
我想念什么？
