Autopano Video - How to create 3D 360 videos v2
This tutorial explains how to create a stereoscopic (3D) 360 video with AutopanoPro v2.
The idea is to create one video for left eye and one video for right eye. After, we just have to merge the two videos in one.
The 3D 360 video can be watched with and Oculus Rift or HTC Vive device.
The solutions used to create this tutorial are:
- Autopano Video Pro 2.2
- Autopano Giga 4.2
For the first steps (synchronization, stitching, stabilization and color correction), do exactly the same as you would do for non-stereoscopic videos, with all the source videos into a same project.
To generate a stereoscopic video, we need to render the videos separately, one for the left eye and one for the right eye.
To do so, we need to tell Autopano Video what goes left and what goes right. Click on "Render" button, go to the "Stereo settings" tab and click on "Stereo mode" to enable stereo rendering. From here, you can assign each source video, or side of source video, to an eye.
At the bottom of the tab "Stereo settings" choose the eye you want to render. Then, if you click on Apply button, the settings will be used in the preview. If you click on OK, this eye will be rendered. Render the both eyes this way in two separate video files.
Merge the two videos...
You can use a tool like ffmpeg (http://www.ffmpeg.org/download.html) to merge the videos into one.
Here is the command line to have a video with left eye on top and right eye on bottom :
* ffmpeg -i left.mp4 -vf "[in] pad=iw:2*ih [left]; movie=right.mp4 [right];[left][right] overlay=0:main_h/2 [out]" output.mp4
Video Side by Side
Here is the command line to have a video with left eye on left and right eye on right :
* ffmpeg -i left.mp4 -vf "[in] pad=2*iw:ih [left]; movie=right.mp4 [right];[left][right] overlay=main_w/2:0 [out]" output.mp4
... and play it
Use GoPro VR Player and an Oculus Rift or an HTC Vive device to watch the result.
