Monoscopic – Stereoscopic video


Monoscopic – Stereoscopic video: Basically Monoscopic is when there is one single point of view in the recording, while stereoscopic is when there is a separate recording for both eyes.

This part is to discuss the content creation for VR using cameras capturing the real world.

First it is worth to make some definitions to clarify the basic vocabulary. to make this i’m using articles on the Samsung VR page and other sources mentioned as well below.

Monoscopic – Stereoscopic video:

The most commonly filmed content for VR are monoscopic 360° videos. These videos are typically filmed using one camera per field of view (FOV) and are stitched together to form a single equirectangular video. Monoscopic video has fewer technical challenges than stereoscopic video, making it the easiest and cheapest option for 360° video productions. A common camera setup involves six cameras filming six different fields of view. Each camera’s footage is stitched together to form a single equirectangular video.

Monoscopic camera setups are generally the easiest and lowest cost setup. These camera setups vary from single cameras with a 360 mirror, to two 360×180 cameras back-to-back, or even fourteen camera setups to cover multiple fields of view. Keep in mind that increasing the number of cameras in your setup means you will see higher equipment costs and the video stitching required to complete video production becomes more complex.

Stereoscopic videos are usually filmed with two cameras per field of view or one camera mapped to each eye, giving the perception of depth. While this experience is great when done correctly, it is much harder to get right. You will need to stitch camera footage for each eye separately and then create a side-by-side (SBS) 3D video mapping the left and right video to each eye. The SBS 3D video comes in a few configurations—top and bottom or right and left side-by-side. It is important to note that stereoscopic 3D decreases video resolution because the two side-by-side videos split the resolution of the screen. The maximum output resolution for a 3D video at 30 fps is 1920×960 (half of the 3480×1920 for monoscopic video) or 1440×670 at 60 fps. The lower resolution can lead to blurring and loss of detail. This is why most content creators prefer to create higher resolution, monoscopic videos.
