FFmpeg with an optional library vidstab can stabilize and smooth out shaky video on Linux. Here is a quick how-to and example video!
Grab FFmpeg with libvidstab enabled
To use vid.stab and stabilize videos, an FFmpeg binary with this compile time option is required:
--enable-libvidstab
Most distros included this. However if not:
* One can compile FFmpeg and vid.stab from source (see below).
Other options:
* Use an FFmpeg static build from here which has vid.stab enabled:
https://www.johnvansickle.com/ffmpeg/
* For Debian, the deb-multimedia.org FFmpeg has vid.stab enabled as an option
* Other distros: many have vid.stab enabled in their FFmpeg build. Check by running $ ffmpeg with no options from the command line.
Compile from source on Debian / Ubuntu quick how-to:
First, install some dependencies
sudo apt install yasm nasm \
build-essential cmake automake autoconf \
libtool pkg-config libcurl4-openssl-dev \
intltool libxml2-dev libgtk2.0-dev \
libnotify-dev libglib2.0-dev libevent-dev \
checkinstall libavcodec-extra57
Next, install the latest vid.stab repo which is what provides video stabilization for FFmpeg
git clone https://github.com/georgmartius/vid.stab.git cd vid.stab/ cmake . make -j4 sudo checkinstall
Next, compile FFmpeg
sudo apt build-dep ffmpeg git clone git://git.videolan.org/ffmpeg.git cd ffmpeg ./configure --prefix=/usr/local --extra-version=1+b3 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --shlibdir=/usr/lib/x86_64-linux-gnu --cc=cc --cxx=g++ --enable-gpl --disable-stripping --enable-shared --disable-decoder=libopenjpeg --disable-decoder=libschroedinger --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libebur128 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librubberband --enable-librtmp --enable-libschroedinger --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzvbi --enable-openal --enable-opengl --enable-x11grab --enable-libdc1394 --enable-libiec61883 --enable-libzmq --enable-frei0r --enable-chromaprint --enable-libopencv --enable-libx264 --enable-pic --enable-nonfree --enable-libvidstab make -j4 sudo checkinstall
Example Stabilization Commands
Option A:
Stabilize a video using default settings for a quick fix:
ffmpeg -i input.mp4 -vf vidstabtransform,unsharp=5:5:0.8:3:3:0.4 output.mp4
Option B:
Better: First let FFmpeg analyze the video (No changes are made- this just makes a file called transform.trf)
1. Analyze with default values:
ffmpeg -i input.mp4 -vf vidstabdetect -f null -
Or analyze a very shaky video, on a scale of 1-10:
ffmpeg -i input.mp4 -vf vidstabdetect=shakiness=10:accuracy=15 -f null -
2. Next, use that generated file transform.trf to help better stabilize the video:
ffmpeg -i input.mp4 -vf vidstabtransform=smoothing=30:input="transforms.trf" output.mp4
Done.
Bonus:
Make a side by side video with:
ffmpeg -i video1.mp4 -i video2.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, pad=iw*2:ih[bg]; [1:v]setpts=PTS-STARTPTS[fg]; [bg][fg]overlay=w" side_by_side.mp4
Here is a side by side comparison of very shaky video stabilized with FFmpeg and vid.stab. Left is original and right is stabilized.
