Add Custom Text Overlays to Your Videos Add text, titles, and captions to your videos.

The Video Text Overlay tool renders text on each video frame using the Canvas 2D context's fillText() and strokeText() methods. Text properties (font family, size, weight, color, alignment) are set via Canvas context properties. Position is calculated based on the user's selection (top, center, bottom, or custom coordinates). For text with a background, a filled rectangle is drawn behind the text using measureText() for accurate sizing. During processing, each video frame is first drawn onto the Canvas, then the text is rendered on top. The composite frame is captured by MediaRecorder. Text shadow and outline effects are achieved using strokeText() with a contrasting color drawn before fillText() for readability.
