vgui_movie_display is a point entity available in all Source games since Alien Swarm. (also in )

vgui_movie_display on elevator screens in Portal 2. The video shown on the screen are located in portal2\media\exercises_horiz.bik.

This entity is used to display videos in the world. Portal 2 uses the Bink format for videos, while Portal 2: Community Edition (along with all Strata Source games) uses the WebM format.

A movie screen is typically a brush face textured with elevator/elevator_screen or one of its variants. Make sure you click "Fit" in the Texture Application Tool.

Bug:

• Non-functional in .
• If the video has sound, it will be heard at full volume everywhere in the map.
• The video restarts when pausing and unpausing the game.
• The movie display does not fade into fog, and rarely is visible through walls.  [todo tested in ?]

Stretching movies across multiple screens

The master/slave keyvalues and U/V inputs on the entity can be used to stretch a movie across multiple displays. The usual setup for this involves one vgui_movie_display with "_master" at the end of its targetname, which then controls a group of slave vgui_movie_displays that have "Forced Slave" enabled and the same "Group Name" as the master entity.

Place a slave vgui_movie_display for each screen at the lower-left corner of the face. Change the width and height to match each panel. The U/V inputs can be used to set which part of the image is displayed on each screen.

To start the movie, fire an "Enable" input at all vgui_movie_display entities; wildcards are useful for this.

Elevator videos

Valve includes a system for selecting elevator videos in custom maps. The arrival_departure_transition_ents instance includes a pair of instance parameters which can be used to set the arrival and departure videos respectively. The video_splitter.nut VScript will automatically handle setting the correct U/Vs.

Unfortunately, the default instances included in Portal 2 have broken elevator videos since the Perpetual Testing Initiative update. To fix, visit this steam guide.

Property Name	Value
Fix up Name
VMF Filename	instances/transitions/arrival_departure_transition_ents.vmf
Replace	$arrival_video media/faithplate.bik
Replace	$departure_video media/animalking.bik

The video_splitter script also contains a list of all singleplayer campaign maps and which videos each map should play. For mods, it is recommended to add the mod's maps to this list. Single maps should continue to use the method above.
