You should kindly also show us the complete, uncut console output of your command. You also didn't point out how much CPU usage you were encountering, and what kind of CPU. On my age old, crappy Intel CPU, encoding a still image of that size takes about 10% CPU (even if I drop your quite extreme "-crf 1" - why are you using that?).
