Methods and apparatus for re-stabilizing video in post-processing

A camera apparatus, comprising:

• a camera;
• an orientation sensor;
• a processor;
• and
• a non-transitory computer-readable medium that stores instructions when executed by the processor, causes the camera apparatus to:
• capture a video comprising a series of frames;
• determine a plurality of camera orientations based on the orientation sensor for the series of frames;
• determine a plurality of corresponding frame orientations to counteract the plurality of camera orientations for the series of frames;
• crop the series of frames based on the plurality of corresponding frame orientations to create a cropped video having a designated view and margin data;
• encode the cropped video within a video track of a video file;
• encode the margin data within a margin track of the video file;
• and
• encode the plurality of camera orientations and the plurality of corresponding frame orientations within an orientation metadata track of the video file.

A camera-aware post-processing apparatus, comprising:

• a processor;
• and
• a non-transitory computer-readable medium that stores instructions which when executed by the processor, causes the camera-aware post-processing apparatus to:
• obtain a margin data and an orientation metadata corresponding to a video data with a first designated view size;
• reconstruct a set of previously stabilized frames from the video data and the margin data based on the orientation metadata;
• and
• generate a re-stabilized video from the set of previously stabilized frames with a second designated view size having a resolution larger of at least one dimension than the first designated view size.
