Subtitle Quality Assurance & QC Checklist Subtitles

Subtitle Quality Assurance & QC Checklist is an important format in the world of subtitles and captions. Subtitle quality assurance (QA) is a systematic process for verifying that subtitle files meet professional standards before delivery. A thorough QA checklist covers timing accuracy, text accuracy, formatting compliance, and technical validation. Timing checks should verify that subtitles appear within 0.5 seconds of the corresponding speech onset, that subtitle duration allows comfortable reading at no more than 20 characters per second, that minimum display time is at least 1 second, and that gaps between consecutive subtitles are at least 2 frames. Text accuracy checks should verify correct spelling, grammar, and punctuation, that proper names and technical terms are spelled consistently throughout the file, that numbers and measurements use the correct format for the target locale, and that no dialogue has been omitted or incorrectly attributed. Formatting checks should verify that line lengths do not exceed 42 characters, that no more than two lines are displayed simultaneously, that line breaks follow linguistic segmentation rules, and that text alignment and positioning are consistent. Technical validation should confirm that the file encoding is UTF-8, that timestamps are properly formatted and sequential, that there are no overlapping subtitle entries, and that the file is valid for its declared format. Automated QA tools can catch many of these issues, but human review remains essential for context-dependent quality factors like translation accuracy, cultural appropriateness, and subtitle segmentation quality. Professional subtitle QA typically involves both automated validation and at least one full human review pass.
