1. A post-processing apparatus, comprising:
a processor subsystem; and
a non-transitory computer-readable medium that stores instructions which when executed by the processor subsystem, causes the post-processing apparatus to:
obtain a video comprising previously stabilized rectilinear image data according to an originally captured view;
obtain a margin track that corresponds to the previously stabilized rectilinear image data;
obtain telemetry data and a lens characteristic;
determine a new view based on the previously stabilized rectilinear image data and at least one of the margin track, the telemetry data, and the lens characteristic;
correct a first portion of the previously stabilized rectilinear image data and a second portion of the margin track based on the lens characteristic;
stabilize the first portion of the previously stabilized rectilinear image data and the second portion of the margin track based on the telemetry data; and
stitch the first portion and the second portion into a video frame.
