Even though the main focus of the Oculus Rift is virtual reality experiences, many users would also want to be able to use this HMD device for other simpler things like playback of 2D and 3D video as well. The good news is that the latest version 2.0.5 of the Stereoscopic Player released earlier this month brought support for 2D and 3D video playback on the Rift, of course there is no support for the head tracker, but you don’t need it for video playback anyway. To enable the right viewing mode just select Oculus Rift in the Settings under the Playback Options panel and the videos you open either in 2D (monoscopic) or in 3D mode (stereoscopic) will be rendered with the correct optical distortion required by the Rift.
The playback of both 2D and stereo 3D videos with the Stereoscopic Player on the Rift works quite well with 3D videos obviously being more impressive than the flat 2D ones that just show the same image for each eye. A stereo 3D video with more depth can look quite impressive when viewed with the Oculus Rift. The only drawback however is that when viewing 1080p 3D videos they need to be scaled down and there is quite a lot of vertical screen space left unused because of the wide aspect. As a result you may be able to notice the top and bottom edges of the video frame when watching the video with the Rift, so have that in mind.
