I can’t go because of the Corona Virus…
I’ve sworn an oath of solitude til the blight is purged from these lands!
To create audio-less copies of all the .mp4 videos in a folder, execute the following:
find . -type f -name "*.mp4" -exec bash -c 'FILE="$1"; ffmpeg -i "${FILE}" -c copy -an "${FILE%.mp4}.ns.mp4";' _ '{}' \;
For a single file, the command would be:
ffmpeg -i input.mp4 -c copy -an output.mp4
First install gif.ski using snap.
snap install gifski;
Then use ffmpeg to break down your video to frames:
ffmpeg -i video.mp4 frame%05d.png;
Finally use gif.ski to create your gif from the frames:
gifski -o clip.gif frame*.png;
Delete the frames if you do not need them, they will be taking a lot of space.
Below are the commands to build vid.stab and ffmpeg on Ubuntu 20.04LTS. (We did not include libaom).
sudo apt-get install build-essential cmake nasm libx264-dev libx265-dev libnuma-dev libvpx-dev libfdk-aac-dev libmp3lame-dev libopus-dev libunistring-dev mkdir ~/ffmpeg_sources ~/ffmpeg_build ~/bin cd ~/ffmpeg_sources wget https://github.com/georgmartius/vid.stab/archive/master.zip unzip master.zip cd vid.stab-master cmake -DCMAKE_INSTALL_PREFIX:PATH=~/ffmpeg_build . make make install sudo apt-get update -qq && sudo apt-get -y install \ autoconf \ automake \ build-essential \ cmake \ git-core \ libass-dev \ libfreetype6-dev \ libgnutls28-dev \ libsdl2-dev \ libtool \ libva-dev \ libvdpau-dev \ libvorbis-dev \ libxcb1-dev \ libxcb-shm0-dev \ libxcb-xfixes0-dev \ pkg-config \ texinfo \ wget \ yasm \ zlib1g-dev wget ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && \ tar xjvf ffmpeg-snapshot.tar.bz2 && \ cd ffmpeg && \ PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \ --prefix="$HOME/ffmpeg_build" \ --pkg-config-flags="--static" \ --extra-cflags="-I$HOME/ffmpeg_build/include" \ --extra-ldflags="-L$HOME/ffmpeg_build/lib" \ --extra-libs="-lpthread -lm" \ --bindir="$HOME/bin" \ --enable-gpl \ --enable-gnutls \ --disable-libaom \ --enable-libass \ --enable-libfdk-aac \ --enable-libfreetype \ --enable-libmp3lame \ --enable-libopus \ --enable-libvorbis \ --enable-libvpx \ --enable-libx264 \ --enable-libx265 \ --enable-nonfree \ --enable-libvidstab && \ PATH="$HOME/bin:$PATH" make && \ make install && \ hash -r source ~/.profile
Using vid.stab with default parameters and two-step process.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/ffmpeg_build/lib #Use these two commands for optimal results: ffmpeg -i input.mp4 -vf vidstabdetect -f null -; ffmpeg -i input.mp4 -vf vidstabtransform=zoom=5:input="transforms.trf" out_stabilized.mp4 #Use this command for a generic solution with the default values ffmpeg -i input.mp4 -vf vidstabtransform,unsharp=5:5:0.8:3:3:0.4 output.vid.stab.mp4;
Using deshake filter for comparison.
ffmpeg -i input.mp4 -vf deshake output.deshake.mp4
