There are three different approches to synchronizing your source videos.
#### 1.1.1 Audio based synchronization
#### Audio based synchronization
Videos are being automatically synchronized based on a loud sound, that stands out from the background noise. A loud clap or a dog training clicker can create such sounds, but it is still not recommended for noisy environments. Make sure the sound is within the working area!
#### 1.1.2 Motion based synchronization
#### Motion based synchronization
Videos are being automatically synchronized based on a strong motion of the camera rig itself.
If your rig allows it, a short, but strong spin would be ideal for this synchronization method.
Make sure both, the start and end of the spin are within the working area.
#### 1.1.3 Flash based synchronization
#### Flash based synchronization
Videos are being automatically synchronized based on a sudden change in lighting that needs to be visible from all cameras.
Turning on bright lights in a room or using synchronized professional flashes would work for this method.
Make sure the change of lighting is within the working area.
If your footage wasn't optimized for synchronization and it doesn't synchronize good enough with any of the automatic methods (ghosting on moving objects in the calibrated 360° panorama can be a sign for this) you can adjust the frame offset manually.
By clicking on "Manual" you will reach the Manual tab where you see the source video names and frame offset.

To get rid of the ghosting of moving objects in the 360° panorama go to a frame where you can clearly see the ghosting in the "Output" panel, enable input numbers ("Window" > "Output configuration" > "Show input numbers"), locate the source file that isn't synchronized well and the input number assigned to it and manually change the offset until no ghosting occurs.
