Comment (by TomSteck):

 I opened ‚Äčhttp://ffmpeg.zeranoe.com/builds/ and downloaded ffmpeg-20160219
 -git-98a0053-win64-static.7z - git-98a0053 (2016-02-19). I don't know how
 to compile FFmpeg on my Windows 10.

 First I stabilized the video with the shakiness=1
 I am using Python 2.7 to run first psutil.Popen(step1), where step1 is a
 list:
 ['ffmpeg', '-i', 'Young16sec.mp4', '-vf',
 'vidstabdetect=shakiness=1:stepsize=5:result=Young16sec.crf25.xml', '-f',
 'null', 'out.null']

 and for psutil.Popen(step2) step2:
 ['ffmpeg', '-y', '-i', 'Young16sec.mp4', '-vf',
 'vidstabtransform=input=Young16sec.crf25.xml:interpol=bicubic:smoothing=100:optzoom=2:zoomspeed=0.25:maxshift=10:zoom=0,unsharp=5:5:0:5:5:0',
 '-vcodec', 'libx264', '-level', '4.2', '-preset', 'veryslow', '-tune',
 'film', '-crf', '25', '-an', 'Young16sec.crf25.mp4']


 For the second stabilization I set shakiness=10
 Step 1:
 ['ffmpeg', '-i', 'Young16sec.mp4', '-vf',
 'vidstabdetect=shakiness=10:stepsize=5:result=Young16sec.crf25.xml', '-f',
 'null', 'out.null']

 Step 2:
 ['ffmpeg', '-y', '-i', 'Young16sec.mp4', '-vf',
 'vidstabtransform=input=Young16sec.crf25.xml:interpol=bicubic:smoothing=100:optzoom=2:zoomspeed=0.25:maxshift=10:zoom=0,unsharp=5:5:0:5:5:0',
 '-vcodec', 'libx264', '-level', '4.2', '-preset', 'veryslow', '-tune',
 'film', '-crf', '25', '-an', 'Young16sec.crf25.mp4']


 Below is the entire console output from stabilizing the same video file
 using two different shakiness settings.
