RMov

Open, edit, and export QuickTime movies all within Ruby! This is an unofficial wrapper around Apple’s QuickTime C API. Mac OS X required.

Install

Install the gem:

gem install rmov

And then load it in your project:

require 'rmov'

Usage

Use this gem to open QuickTime movies and edit them to your liking.

movie1 = QuickTime::Movie.open("path/to/movie.mov")
movie2 = QuickTime::Movie.open("path/to/another_movie.mov")

# add movie2 to the end of movie1
movie1.append_movie(movie2)

# make a new movie out of a section of movie 1
# this will delete 5 seconds out of the movie at 2 seconds in
movie3 = movie1.clip_section(2, 5)

# You can insert that part back into the movie at 8 seconds in
movie1.insert_movie(movie3, 8)

Now you can export the movie. Usually this is done through a user interface the first time around. The settings can then be saved to a file. After that you can load these settings without interfering the user with the dialog again.

exporter = movie1.exporter

# if we already have saved the settings, load those
if File.exist? "settings.st"
  exporter.load_settings("settings.st")
else
  # otherwise open the QuickTime GUI settings dialog
  exporter.open_settings_dialog

  # save settings to a file so we don't have to bother user next time
  exporter.save_settings("settings.st")
end

# export the movie to a file and report the progress along the way
exporter.export("movie.mov") do |progress|
  percent = (progress*100).round
  puts "#{percent}% complete"
end

See QuickTime::Movie in the RDoc for more information.
