Set-up

1. Install Homebrew
2. Install imagemagick

brew install imagemagick

3. Install ffmpeg

brew install ffmpeg

4. Install rmtrash

brew install rmtrash

Run

1. Open up your Terminal.app
   • easiest is to hit command+space, bring up spotlight, and type in "Terminal"
2. Run the script.
   • Assume you downloaded a zip file to ~/Downloads/auto-logo-and-merge-master.zip and unzipped the folder auto-logo-and-merge-master. Here is a working example.

cd ~/Downloads/auto-logo-and-merge-master/
chmod +x run.sh
./run.sh img/P1BHs.png mp4/video-trim-noaudio.mp4 mp4/audio-layer.m4a mp4/merged-ryan.mp4 "949-555-5555" "www.gramnegative.com"

How it works

It uses the following syntax:

./run.sh path/to/logo.png  path/to/video.mp4  path/to/audio.mp3  path/to/output.mp4  "999-999-9999"  "www.somewebsite.com"

The last two variables are optional. They default to blank. NOTE: Must use DOUBLE quotes "".

It is SUPER IMPORTANT that you use relative or full paths. For example, relative paths like img/P1BHs.png or ./img/P1BHs.png work, as do full paths like /Users/dnoriega/GitHub/auto-logo-and-merge/img/P1BHs.png.

But /img/P1BHs.png fails because the program assumes absolute paths when you start with a / and will read it as such. Hence, a full path is just an absolute path to the file. I recommend using relative paths. Just remember: don't start with / when using relative paths!

(This distinction was what kept me from getting the thing to work for like 2 hours. So annoying.)

To-do

You can get imagemagick to use system fonts by following instructions here: http://gothick.org.uk/2008/03/14/using-os-x-fonts-in-imagemagick/

Once updated, you can change fonts used in the script gen-logo.sh. In this particular case, change the -font Arial to whatever font you'd like.

convert -size 1280x100 xc:white -font Arial -pointsize 72 -gravity center \
  -stroke black -annotate 0 "$PHONE" \
  ./img/phone.png;

You can see the font list typing convert -list font.
