Video content alignment

A computing system, comprising:

• a processor;
• and memory including instructions that, when executed by the processor, cause the computing system to:
• receive a first video file and a second video file, the first video file including a first plurality of frames and the second video file including a second plurality of frames, each frame of the first plurality of frames segmented into one or more cells, each frame of the second plurality of frames segmented into one or more cells;
• generate a first fingerprint for each frame of a first subset of frames of the first plurality of frames based at least in part on an intensity value associated with the one or more cells of each frame of the first subset of frames;
• generate a second fingerprint for each frame of a second subset of frames of the second plurality of frames based at least in part on an intensity value associated with the one or more cells of each frame of the second subset of frames;
• generate a first encoded representation of the first fingerprints for the first video file input and a second encoded representation of the second fingerprints for the second video file input;
• identify a first set of unique fingerprints from the first encoded representation and a second set of unique fingerprints from the second encoded representation;
• compare the first set of unique fingerprints to the second set of unique fingerprints;
• segment the first video file input into a plurality of first segments and the second video file input into a plurality of second segments based at least in part on comparing the first set of unique fingerprints to the second set of unique fingerprints;
• and align each first segment of the plurality of first segments with a corresponding second segment of the plurality of second segments, wherein generating the version fingerprint for each frame of the version of the video file further includes:
• segmenting each frame into a plurality of cells;
• and positioning a rectangular canonical window divided into the plurality of segments relative to a center of the frame, the frame having a first size and the rectangular canonical window having a second size that is smaller than the first size.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause a computing device to:

• for each version of a video file:
• segment the video file into a plurality of frames, each frame of the plurality of frames segmented into one or more cells;
• generate a fingerprint for each frame of the version based at least in part on an average intensity value for each cell of the version of the video file;
• generate a run-length encoded representation of each version's fingerprints for the version of the video file;
• identify a set of unique fingerprints of each version from the run-length encoded representation;
• determine a set of split points for the version of the video file based at least in part upon a plurality of matching unique fingerprints between each set of unique fingerprints for each version;
• and segment the version of the video file into a plurality of version segments using the set of split points;
• determine individual frame correspondences between each version segment of the plurality of version segments and a corresponding version segment of a plurality of corresponding version segments;
• and concatenate the plurality of the version segments and the plurality of corresponding version segments based at least in part on the individual frame correspondences, wherein generating the version fingerprint for each frame of the version of the video file further includes:
• segmenting each frame into a plurality of cells;
• and positioning a rectangular canonical window divided into the plurality of segments relative to a center of the frame, the frame having a first size and the rectangular canonical window having a second size that is smaller than the first size.
