How to add upload a 3D video Side by Side on YouTube 3D (YT3D enable)

IMPORTANT: (YT tags field) add ONLY following TAGS:

yt3d:enable=true yt3d:aspect=16:9 yt3d:swap=true

“yt3d:enable=true”: to enable YouTube 3D mode

“yt3d:aspect=16:9”: If your footage is 16×9 aspect ratio also add the tag

“yt3d:swap=true” YouTube 3D expected crossview formatted side by side so if you exported as side by side parallel instead of crossview you will need to add the tag to ensure the left and right eyes are presented correctly.
