• Convert 3d Blu-ray Discs to anaglyph 3d.
  • I used this process during October since that's when you look most dope in glasses

anaglyph.red_cyan.color

anaglyph.red_cyan.color_optimized

anaglyph.red_cyan.grey

anaglyph.red_cyan.half_colored

• Using a modified Blu-ray Drive I can make backups of my movies using MakeMKV
  • Ensuring to include the 3d element option
• Output is a normal mkv file that can be played as 2D Film
  • The 3D Element is embedded in the file itself.
• Example Info

  Stereo [email protected]/ [email protected]
      Both Eyes laced in one block (left eye first)
      stereo_mode: block_lr
  

• It requires some work to get the file ready to be converted to anaglyph 3d.
• Currently, the initial step must be done with the BD3D2MK3D GUI to generate the side by side file.
• Steps:

  1. Open file in program

  2. Select full side-by-side

  3. Tune to film and slow with CRF at 18

     • Maybe doesn't need to be so low, but there is still another step of conversion so I like to keep the video as crips as can be
     • Allow program to finish creating a setup

  4. A new window opens, choose __ENCODE_3D_LAUNCHER.cmd

  • I have this set to be in the same directory as the movie
  • Launching will then generate the file as a side-by-side mkv file
  • For our purposes I used the original 3D movie House of Wax

• Once we have our prepped file we can now use ffmpeg to convert our file to various versions of anaglyph 3D.
• Below if a script written in python as a wrapper to allow for movies to be converted into a few variance of the red/cyan anaglyph format.

• Programs needed to complete the 3d conversion

• Forum
• Home Page
• Requires AviSynth as a frame server
• Doesn't seem to allow anaglyph directly
• Does allow for Side by Side at full size
  • This can then be converted to anaglyph later

• Current Release
• HomePage
• Needed as a frame server for BD3D2MK3D
• This some kind of video scripting language
  • the output is video instead of text

• Probably not useful for makemkv mkv to 3D direct
  • Will probably need to use BD3DMK3D to use full side by side and then anaglyph
