What If Captions Don't Work or Look Wrong?
No CC button visible: The video has no caption track. Not all YouTube videos have captions — this is common for older videos, very new uploads (auto-captions take a few hours), or videos in less common languages.
Captions are inaccurate: YouTube's auto-generated captions use speech recognition that's ~90-95% accurate for clear English. For corrected captions, the video creator needs to manually edit and upload a caption file.
