The best moment for stitching is:
- No motion of the cameras: when the cameras are not moving, you suffer no more of residual desynchronization, rolling shutter and motion blur.
- No close object: if you stitch videos coming from a camera rig, nodal points of the cameras cannot be perfectly superimposed. Then, the stitching will compensate the parallax in a way that is too specific to the current surrounding 3D scene. The less you have close objects the less the stitching will be instant-specific.
- Visual information: the current time must not suffer of a lack of visual content due to blue sky, uniform color walls...
