What is the question?

We need to see the complete/unedited output from the command you ran, and 
you need use the most current build of ffmpeg (which may be newer than the

I converted the mp4 video clips into key frames, using the above hardware and 
commands, the video became very blurred after the conversion. The video bit 
rate is very high and should not be the case.
