QA DOC 1

Review 

1. Functional Testing

• Playback Controls: Verify that Play, Pause, Seek (Forward/Backward), and Replay function without lagging or audio-sync issues.

• Resolution Switching: Test how the video behaves when switching between 4K, 1080p, and Auto (adaptive bitrate) modes.

• Bookmark/Resume: Ensure the documentary resumes from the exact timestamp where the user last stopped.

• Audio Balancing: Documentaries often mix voiceovers, archival footage, and background music. Check that the music does not drown out the narrator's voice.

• Archival Footage Handling: Verify that older, lower-resolution clips are scaled correctly without aspect ratio distortion (e.g., preventing "stretching").

• Color Consistency: Ensure that color grading remains consistent across different interview segments and B-roll footage.

• Subtitles/Closed Captions (CC):

  • Verify that text matches the spoken dialogue word-for-word.

  • Check that captions for "Non-Speech Sounds" (e.g., [Tense music builds], [Wind howling]) are present and timed correctly.

• Multi-language Audio: If the documentary is dubbed, ensure the lip-sync is as accurate as possible and that the tone matches the original speaker.

• Chapters: Test the "Chapter Markers" to ensure they lead to the correct segments (e.g., "Introduction," "The Discovery," "Conclusion").

• Credits: Verify that the end credits scroll smoothly and that all contributors, sponsors, and archival sources are listed correctly.

• Thumbnail Accuracy: Ensure the preview thumbnail is relevant and not a "black frame" or "spoiler" image.
