1. What is a stereoscopic 3D video?
Side-by-side stereoscopic output means that the rendering is divided into two halves, a left view, and a right view, each occupying one-half of the original display area.
In other words, on a 1920x1080 rendering, the 'left eye' image is squashed so that it occupies the leftmost 960 pixels of the 1920x1080 image, and the 'right eye' image occupies the rightmost 960 pixels:
Certain old 3D TVs can convert the side-by-side format videos to 3D whereas others require a conversion procedure.
2. Here's how to render a stereoscopic 3D video
You can export side-by-side stereoscopic Image Sequences and Movies via the Stereoscopic Settings Effect in Movie Mode.
2.1: The effect must be added to the Effects Stack with Entire Movie selected:
2.2: To apply it to the Movie, click on:
- Movie Mode -> Entire Movie -> New effect -> Various tab -> Side by Side 3D Stereo

To make YouTube interpret 'side-by-side' stereoscopic videos the correct way, please follow the instructions below:
a. Download ffmpeg:
- External Link: FFMPEG
b. Extract the FFMPEG archive to a location of your choice.
c. Place your stereoscopic 3D video in the 'bin' folder in the FFMPEG extracted folder.
d. Type 'cmd' in the Windows search field and press Enter.
e. In the Command Line window, go to your FFMPEG 'bin' folder.
f. Copy and paste this command into the Command Line window:
ffmpeg -i EnterInputFileNameHere.mp4 -b:v 30M -b:a 317k -vcodec libx264 -x264opts "frame-packing=3" EnterOutputFileNameHere.mp4 |
Replace EnterInputFileName with the name of your stereoscopic 3D video file.
Replace EnterOutputFileName with the desired file name.
Replace the number next to -b:v with the desired video bitrate.
Replace the number next to -b:a with the desired audio bitrate.
M for megabits, k for kilobits.
g. Press Enter.
h. Upload the .MP4 file to YouTube.
