A computing device for reducing horizontal misalignment in a 360-degree video converts the 360-degree video to a rectilinear 360-degree video. At least a pair of views of rectilinear images from the rectilinear 360-degree video are generated and displayed. A user interface for facilitating adjustment of a view angle is generated, the user interface displaying the at least the pair of views of the rectilinear images from the rectilinear 360-degree video. The computing device obtains vertical reference object is obtained in one of the views of rectilinear images; at least one of: a roll angle adjustment, a pitch angle adjustment, and a yaw angle adjustment for aligning the vertical reference object with a vertical axis; and a view angle adjustment corresponding to reduction of the horizontal misalignment. A panoramic 360-degree video is then generated.

Systems and methods for reducing horizontal misalignment in 360-degree video

A method implemented in a computing device for inserting an effect into a 360 video where the computing device receives the effect from a user. The method receives a target region from the user, the target region corresponding to a location within the 360 video for inserting the effect; for each frame in the 360 video. The method then inserts the effect on a surface of a spherical model based on the target region and generates at least two projection frames containing the effect from the spherical model. The method then stitches the projection frames to generate a panoramic representation of the effect, and blends the panoramic representation of the effect with an original source panorama to generate a modified 360 video frame with the effect.

Methods for rendering effects in 360 video

A computing device for inserting an effect into a 360 video receives the effect from a user. A target region is also received from the user, where the target region corresponds to a location within the 360 video for inserting the effect. Next, the following steps are performed for each frame in the 360 video. The effect is inserted on a surface of a spherical model based on the target region, and two half-sphere frames containing the effect from the spherical model are generated. The two half-sphere frames are stitched to generate a panoramic representation of the effect, and the panoramic representation of the effect is blended with an original source panorama to generate a modified 360 video frame with the effect.
