To ensure your subtitles are readable and professional, follow these industry-standard "rules of thumb" from LanguageWire and Creative Words :
: For "Closed Captions" (CC), include descriptions of relevant background sounds, such as [Door creaks] or [Tense music playing] , to assist viewers who are deaf or hard of hearing.
: Ensure text appears exactly when the speaker starts and disappears when they stop. A new subtitle should generally start with every scene change.
: Use clear, high-contrast fonts (white with a black outline/shadow is standard). If the background is too light, consider using a semi-transparent dark box behind the text. 2. Recommended Auto-Subtitle Tools
: Keep text on screen for at least 1.5 seconds (for very short phrases) and no more than 7 to 8 seconds for longer blocks to allow viewers time to read.
