How to speed up the execution of commands (a set of filters?)?

Question

fmpeg

I need to speed up, stick a watermark and blur:

ffmpeg -i 1.mp4 -vf "setpts=PTS/5" 2.mp4
ffmpeg -i 2.mp4 -vf "movie=f.png [watermark]; [in] [watermark] overlay=0:0 [out]" 3.mp4
ffmpeg -i 3.mp4 -vf "boxblur=5" 4.mp4

Can this be accelerated somehow?
takes a very long time, you need to do it several times faster
