"Images" is a vague term and it certainly contradicts "-f mp4".

(What is "/b"?)
Why do you copy audio if you are only interested in video?

You are expected to not only post your command line but also the complete, 
uncut console output if you need support.

Please do not top-post here, it is considered rude.
Please do not repeat the same question in different threads.
Please use describing lines for your subject, "need help" is not better 
than "hi" (nearly all people who post here need help), "export different frame 
types as images" might have been an alternative.
