Use the video codec "rawvideo" with that pixel format for output, except
AFAICT that there is no video encoder "rawvideo" (that should throw an
error, which because of the missing command output, we don't see).

The answer depends on too many parameters.
i.e, basically I want to know how much time it takes to compress with
different presets and how much time it

Yes, I want raw video. I have converted RAW files to .mp4 successfully with

Yes, I know it cannot be played with most of th players, I need to see the
size of the RAW video and make some compression on it for our further
analysis.

You forgot to specify the input pixel format.
Many parameters are missing for the raw output. But the error message is
from the input.
Do you really want raw video? That's not the easiest format

It really sounds as if you haven't studied the documentation very well.
