Movie link

Ren'Py is capable of using libav (included) to play movies using the video codecs:

  • VP9
  • VP8
  • Theora
  • MPEG-4 part 2 (including Xvid and DivX)
  • MPEG-2
  • MPEG-1

and the following audio codecs:

  • Opus
  • Vorbis
  • MP3
  • MP2
  • PCM

inside the following container formats:

  • WebM
  • Matroska
  • Ogg
  • AVI
  • Various kinds of MPEG stream.

(Note that using some of these formats may require patent licenses. When in doubt, and especially for commercial games, we recommend using VP9, VP8, or Theora; Opus or Vorbis; and WebM, Matroska, or Ogg.)

Movies can be displayed fullscreen or in a displayable. Fullscreen movies are more efficient.

Fullscreen Movies link

The easiest and most efficient way to display a movie fullscreen is to use the renpy.movie_cutscene() function. This function displays the movie fullscreen until it either ends, or the player clicks to dismiss it.

$ renpy.movie_cutscene("On_Your_Mark.webm")

On mobile platforms, such as Android and iOS, hardware video decoding is used when config.hw_video is True, the default. This is generally much faster, but the list of supported movie formats depends on the platform. See for instance Android's supported media formats. A quick way to test if your videos are supported is to copy them to your target device and play them with its default video player.

Movie Displayables and Movie Sprites link

The Movie displayable can be used to display a movie anywhere Ren'Py can show a displayable. For example, a movie can be displayed as the background of a menu screen, or as a background.

The Movie displayable can also be used to define a movie sprite, which is a sprite that is backed by two movies. The primary movie provides the color of the sprite. A second movie, the mask movie, provides the alpha channel, with white being full opacity and black being full transparency.

Movies played by the Movie displayable loop automatically.

A Movie takes two parameters:

play

A string giving the name of a movie file to play.

This should always be provided.

mask
A string giving the name of a movie file to use as an alpha mask. It should be the same size, duration, and framerate as the movie file provided to play.

Here's an example of defining a movie sprite:

image eileen movie = Movie(play="eileen_movie.webm", mask="eileen_mask.webm")

The movie sprite can be shown using the show statement, which automatically starts the movie playing. It will be automatically stopped when the displayable is hidden.

show eileen movie

e "I'm feeling quite animated today."

hide eileen

e "But there's no point on wasting energy when I'm not around."

A Movie displayable can also be used as part of a screen, provided it is created during the init phase (for example, as part of an image statement.)

image main_menu = Movie(play="main_menu.ogv")

screen main_menu:
    add "main_menu"
    textbutton "Start" action Start() xalign 0.5 yalign 0.5

Multiple movie displayables or sprites can be displayed on the screen at once, subject to system performance, and provided all share the same framerate. The behavior of Ren'Py when displaying movies with different framerates is undefined, but will likely include a significant amount of frame drop.
