===== FFmpeg =====



==== Video Stabilization with FFmpeg ====


=== Install Vidstab ===
For Ubuntu Trusty 16.04 install the [[http://public.hronopik.de/vid.stab/|vidstab]] filter.\\
   sudo add-apt-repository ppa:mc3man/ffmpeg-test
   sudo apt-get update
   sudo apt-get install ffmpeg-static
   hash -r
Now run ffmpeg2 (note the "2").\\
For Arch Linux vidstab is already included, one can just use ffmpeg.\\

=== Calculating the Stabilization Vectors ===
   ffmpeg2 -i SHAKY_INPUT_VIDEO.mp4 -vf vidstabdetect=stepsize=6:shakiness=8:accuracy=9:result=transform_vectors.trf -f null -
=== Transcoding the Video ===
   ffmpeg2 -i SHAKY_INPUT_VIDEO.mp4 -vf vidstabtransform=input=transform_vectors.trf:zoom=1:smoothing=30,unsharp=5:5:0.8:3:3:0.4 -vcodec libx264 -preset slow -tune film -crf 18 -acodec copy SMOOTH_OUTPUT_VIDEO.mp4
