3D Blu-ray conversion to 2D-video?

Hi. I wonder, how can I convert a 3D Blu-ray into a 2D-video for encoding in x265? I noticed that the media-player PowerDVD asks (on playback) if I want to see the 2D-version of the 3D Blu-ray or not.
eac3to info of the source,
Quote:
M2TS, 2 video tracks, 1 audio track, 2 subtitle tracks, 0:43:19, 24p /1.001
1: Chapters, 5 chapters
2: h264/AVC (left eye), 1080p24 /1.001 (16:9)
3: h264/MVC (right eye), 1080p24 /1.001 (16:9)
4: DTS Master Audio, English, 5.1 channels, 24 bits, 48kHz
(core: DTS, 5.1 channels, 1509kbps, 48kHz)
5: Subtitle (PGS), English
6: Subtitle (PGS), English

I would look through the Blu-Ray files and see if a 2D version is somewhere on the disc or if you can extract only the left side.

If Not

You could try this: http://rationalqm.us/dgmvcsource/dgmvcsource100b22.zip

with the Following Code:

Quote:
vid=dgmvcsource("base.264","dependent.264",view=0,frames=2000)
left=vid.selecteven()
right=vid.selectodd()
stackhorizontal(horizontalreduceby2(left),horizontalreduceby2(right))
or
This only returns the left side.

Quote:
dgmvcsource("combined.264","",view=1,frames=2000)
or
dgmvcsource("base.264","dependent.264",view=1,frames=2000)
I never tried to covert to 2D from a 3D source, I have no idea if these methods will work or not.

You could also try FFMPEG. The following code was taken from a programming forum.

Code:
ffmpeg -i the_3d_video.mp4 -r 29  -vf
"crop=w=iw/2:h=ih:x=0:y=0,scale=w=2*iw:h=ih,setdar=2"  -y the_2d_video.mp4

Or you could try re-encoding just the left eye view
...Revan654 answered just a little faster

Remux to MKV and deselect the right eye view
