lowerthird v0.0.3

Lowerthird

This cli tool will help you to generate lower third banners videos (with a fine green screen background) just like those you see in the streaming shows. It is basically a simple wrapper for these fine pieces of software:

• Matt Chestnuts lower third animations with CSS
• Łukasz Nawrot elegant record-page

Requisites

• You will need ffmpeg in your system to produce the video from the individual frames

# instructions for Ubuntu 20.04

sudo apt update
sudo apt install ffmpeg -y

• Chrome is used to run the html code and should be available in your system

sudo apt-get install -y libappindicator1 fonts-liberation
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo dpkg -i google-chrome*.deb

• Get a decent version of nodejs

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

nvm install --lts 

Running the tool

• Set the path to Chrome

export CHROME_PATH=/usr/bin/google-chrome-stable

• Execute lowerthird without installing it

npx lowerthird "The original Matrix film was released on 1999" -t "Fun fact" --fps 60 --seconds 8

Options

• Execute lowerthird without any parameter to see the syntax and available options

npx lowerthird

• This is the output text that will appear

lowerthird message [--title title] [--output filename] [--fps frames-per-second] [--seconds number-of-seconds]
