Deus Ex: The Conspiracy (2002) is the PlayStation 2 port of the original Deus Ex. While it can't be said to have been an improvement over the original as it had to be simplified for a console release, it had some interesting additions. Most notably the character models and the cinematic cutscenes that replaced the Intro and the three ending sequences--Merge with Helios, Illuminati Rule, and A New Dark Age. In this post I will demonstrate how to extract these four videos from the game.

Locating the video files

  1. Insert the PS2 disk or mount an .ISO image file of the PS2 disk

  2. Browse the contents of the disk to find the .PSS files (PS2 video)

  3. Copy these files off the disk and into a folder on your Desktop

Extracting the audio and video stream from the .PSS file

  1. Extract the contents of the PSS Demux archive and run PSS_demux.exe

  2. Drop the .PSS files onto the window

  3. The window will now display the progress of the conversion and will inform you once it is done

  4. In the folder, there should now be video (in .M2V) and audio files (in .WAV) for each of the cutscenes

Combine the audio and video stream into one file using MKVToolNix (simple/GUI)

  1. Open MKVToolNix > Multiplexer tab > Source files > right click the box > select Add files

  2. Select the video and audio stream for a specific cutscene, in this example I chose the Helios ending > click the Start Multiplexing button at the bottom

  3. When the progress bar at the bottom right says 100% it should be complete

  4. In the output folder, there will be an .MKV file that has the audio and video combined

  5. It can now be played as normal

Combine the audio and video stream into one file using FFmpeg (complex/CLI)

Note: This method assumes you already have FFmpeg installed and accessible via Command Prompt (it has been added to your path environmental variable). If you don't, here are installation instructions for Windows.
