1. A video processing method comprising:
receiving an omnidirectional content corresponding to a sphere;
obtaining a plurality of projection faces of a three-dimensional object from the omnidirectional content of the sphere, wherein the omnidirectional content of the sphere is mapped onto the projection faces via a 360-degree Virtual Reality (360 VR) projection; and
creating, by a conversion circuit, a projection-based frame by generating at least one padding region and packing the projection faces and said at least one padding region in a 360 VR projection layout, wherein the projection faces comprise a first projection face and a second projection face, where regarding the three-dimensional object, one side of the first projection face does not connect with one side of the second projection face; said at least one padding region packed in the 360 VR projection layout comprises a first padding region, where regarding the 360 VR projection layout, said one side of the first projection face is parallel with said one side of the second projection face, and the first padding region is sandwiched between the first projection face and the second projection face and connects with said one side of the first projection face and said one side of the second projection face for isolating said one side of the first projection face from said one side of the second projection face in the 360 VR projection layout.
