How to set framerate in ffmpeg for video generated from static image

I'm trying to generate a 5 sec video from a static jpeg file. I need an 720p .H264 file with 23.976 fps and AAC 44100Hz 192kb for audio (I'm just creating a 5 sec logo to concatenate it with recorded video in this exact format).

So I'm doing this:

ffmpeg -loop 1 -i logo.jpg -c:v libx264 -t 5 -vf "fps=24/1001" -c:a aac -b:a 192k logo_mov.mp4

And I get a tiny resulting file, that doesn't playback at all. Removing the -vf "fps=24/1001" produces a 5 second video, but in 25fps format. How do I set it up correctly?

The correct fps value is not 24/1001, you are missing a decimal point. The correct value is 24/1.001 which equals23.976
