![]() If the input was ever encoded using a lossy video codec it's recommended to at least halve size of the frames to hide compression artefacts and counter chroma subsampling that was done by the video codec.Īdding -quality=90 may reduce file sizes a bit, but expect to lose a lot of quality for little gain. You can also resize frames (with -W option). If you have ffmpeg installed, you can run in terminal: ffmpeg -i video.webm frame%04d.pngĪnd then make the GIF from the frames: gifski -o anim.gif frame*.png The recommended way is to first export video as PNG frames. There is no GUI for Windows or Linux (there is one for macOS). If you have Rust 1.57+, you can also build it from source with cargo install gifski. If you have Homebrew, you can also get it with brew install gifski. It's a CLI tool, but it can also be compiled as a C library for seamless use in other apps. It produces animated GIFs that use thousands of colors per frame. Gifski converts video frames to GIF animations using pngquant's fancy features for efficient cross-frame palettes and temporal dithering. In some cases, like when you want tighter control, it is a good option rather than adding an entire directory to your PATH and MANPATH.Highest-quality GIF encoder based on pngquant. This way, it would almost as easy to create symbolic links. Ln -s /usr/local/opt/coreutils/bin/sha256sum /usr/local/bin/ which sha256sum # prove it is not on PATH usr/local/bin is a good choice based on looking at echo $PATH. It must be a path that is loaded early on PATH, because the PATH is searched on a first-come, first-serve basis. Then you can create symbolic links from there to a location that is already on your PATH. The /usr/local/opt directory is where Homebrew stores relatively static files that are unlikely to change between updates. You need to know where Homebrew installs coreutils binaries. PATCH=`grep "~/.bash_path" ~/.bash_profile`Įcho "source ~/.bash_path" > ~/.bash_profileĪs an alternative to setting the PATH and MANPATH environment variables (which I would actually recommend), it is also possible to symlink binaries to an existing PATH location like this: # Build PATH variable script in ~/.bash_pathĮcho 'export PATH="'$i':$PATH"' > ~/.bash_pathįor i in /usr/local/Cellar/*/*/libexec/gnubin doįor i in /usr/local/Cellar/*/*/share/man doĮcho 'export MANPATH="'$i':$MANPATH"' > ~/.bash_pathįor i in /usr/local/Cellar/*/*/libexec/gnuman do override-system-vim -custom-system-icons default-names -with-default-names -with-gettext -override-system-vi \ M4 make nano file-formula git less openssh python rsync svn unzip vim \ Gnu-tar gnu-which gnutls grep gzip screen watch wdiff wget bash gdb gpatch \ # Install required packages from Homebrewīrew install coreutils binutils diffutils ed findutils gawk gnu-indent gnu-sed \ # Install Homebrew (if not already installed) Upon running the script, Homebrew will be installed (if not already), all the associated GNU utilities will be installed (if not already), and the PATH variable will be built from the installed utilities. However, I can't always guarantee this post will reflect the latest version of the script linked previously. I've written a script to do exactly this! The script can be viewed here (or below). MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH" The "gnuman" directory to your MANPATH from your bashrc as well: PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"Īdditionally, you can access their man pages with normal names if you add If you really need to use these commands with their normal names, youĬan add a "gnubin" directory to your PATH from your bashrc like: usr/local/Cellar/coreutils/8.21 (210 files, 9.6M) *Īll commands have been installed with the prefix 'g'. If you want to use the commands without a g prefix add for example /usr/local/opt/coreutils/libexec/gnubin before other directories on your PATH. This adds symlinks for GNU utilities with g prefix to /usr/local/bin/: brew install coreutils findutils gnu-tar gnu-sed gawk gnutls gnu-indent gnu-getopt grep
