Detecting errors in the timing between subtitles and shot changes

One or more non-transitory computer-readable storage media including instructions that, when executed by one or more processors, cause the one or more processors to perform the steps of:

• acquiring a plurality of shot changes and a first subtitle associated with an audiovisual program, wherein the plurality of shot changes and the first subtitle are included within a sequence of frames of the audiovisual program;
• determining that the first subtitle is positioned at a first temporal location within the sequence of frames, wherein:
• a first shot change occurs at a second temporal location within the sequence of frames, and
• the first subtitle has a first temporal edge coincident with the first temporal location;
• computing a plurality of timing errors associated with the first subtitle, wherein each timing error in the plurality of timing errors indicates a distance between:
• a different location within the sequence of frames relative to the shot change, and
• the first temporal location;
• determining that a first temporal edge does not satisfy a timing guideline relative to the first shot change that is included in the plurality of shot changes;
• determining, based on a difference between at least a subset of the plurality of timing errors, a second temporal edge for the first subtitle that satisfies the timing guideline relative to the first shot change;
• and
• causing, based on the second temporal edge, the first subtitle to be positioned at a third temporal location within the sequence of frames.

A system, comprising:

• a memory storing a subtitle timing application;
• and
• a processor that is coupled to the memory, wherein, when executed by the processor, the subtitle timing application causes the processor to:
• determine that a first subtitle is positioned at a first temporal location within a sequence of frames of an audiovisual program, wherein:
• a first shot change occurs at a second temporal location within the sequence of frames, and
• the first subtitle has a first temporal edge coincident with the first temporal location;
• determine that the first temporal edge does not satisfy a timing guideline relative to the first shot change;
• compute a plurality of timing errors associated with the first subtitle, wherein each timing error in the plurality if timing errors indicates a distance between:
• a different location within the sequence of frames relative to a shot change, and
• the first temporal location,
• determine, based on a difference between at least a subset of the plurality of timing errors, a second temporal edge for the first subtitle that satisfies the timing guideline relative to the first shot change;
• and
• cause, based on the second temporal edge, the first subtitle to be positioned at a third temporal location within the sequence of frames.
