Burned-in captions (open captions)

In Arabic: الترجمة المدمجة في الفيديو

Transcription and captions

Text drawn into the video picture itself, so it is always visible and cannot be switched off or edited without re-exporting. Ideal for TikTok and Reels, where many people watch with the sound off.

Example: A Reel with large word-by-word Arabic captions mid-screen that still work when the phone is on silent.
