Autopano Video - Anti shake
This tutorial will show you how and when to use the anti-shake feature of Autopano Video 1.6.
WHY AND WHEN TO USE THE ANTI-SHAKE
This tools is meant to compensate the fast moves of the rig, especially the rotation. It does not completely stabilize the entire stitching as you won't keep the horizon straight all among the timeline. Once you have enabled the anti-shake it makes the edition via the timeline much simpler. This feature is a first stabilization pass for your 360 video that does not introduce a crop or a re-scaling like in a classic video stabilization.
As this feature is based on content detection if one of your cameras is not seeing anything (perfect blue sky, completely blurred image, over/under-exposed pictures) it won't work.
Before using the anti-shake you need to have a quiet good stitching of your video and a good synchronization. Use this feature before any timeline editing as you won't keep your horizon after enabling it.

HOW TO USE THE ANTI-SHAKE FEATURE
Before using the anti-shake feature you need to "Compute the motions", during this step your computer is going to calculate the rotation between each frame of every input video. This is a quite long process, depending on you computer and the length of your videos.
Just click on "COMPUTE MOTIONS":
Motion compensation slider
Once the calculation is done you have a motion compensation slider instead of the "Compute motion" button. This slider set the value of the motion compensation from 0% to 100%.
Low values (0-20%) mean that your are going to compensation high frequency moves (vibrations for example).
High values (> 70%) mean that you are going to compensate both high and low frequencies (vibrations + walking moves for example).
The value set on the slider is a low-pass filter, meaning that frequencies under the slider value will be filtered.
These different steps are illustrated in the following video:
