How can I convert a 3D video file from one format to another? Let's say I want to convert a side-by-side formatted file to frame sequential.

I have found Bino, which is a multiplatform free video player which supports following input/output modes (and switching between them):

Input layouts:

  • Monoscopic (2D) video
  • Left and right view in separate video streams and/or files
  • Left and right view side by side (optionally with half width)
  • Left and right view on top of each other (optionally with half height)
  • Left and right view in alternating rows

Output techniques:

  • Anaglyph glasses (red/cyan, green/magenta, amber/blue). This works with every display. Bino uses the high-quality Dubois method to produce anaglyph images. This gives far better results than the usual full-color and half-color methods.
  • Left and right view side by side (used by some 3D displays)
  • Left and right view on top of each other (used by some 3D displays)
  • Left and right view in alternating rows or columns (used by some 3D displays)
  • OpenGL quad-buffered stereo (only available with some graphics cards)

  • It seems to play 3D video files nicely – but any idea on how to save the output? It says it uses ffmpeg libraries but I had no luck using ffmpeg cli myself for that purpose. One problem was that it would halve the fps when using the stereo filter -vf stereo3d=ar:sbsl to get a left-right version. This seems to fit the notion that it does not know about MVC codec and ignores the second frame part.
