Cannot render video out because [Unrecognized option 'preset']

[FlyCole]

Hi,

I'd like to render video out based on a prefixed camera trajectory. However, I met something like:

$ INFO ffmpeg -loglevel error -y -framerate 60 -i tmp/%06d.jpg -c:v libx264 -preset slow -crf 17 -pix_fmt yuv420p "video.mp4"
Unrecognized option 'preset'.
Error splitting the argument list: Option not found
15:18:17 ERROR    Video could not be assembled: FFmpeg failed

My env is: python: 3.11.5 GPU: RTX4090 CUDA 11.8 ffmpeg: 4.3

Could you please help me with that? Thank you.
