What are the limits of Canva for removing video captions?

Canva has many shortcomings in caption removal. It has no professional AI inpainting function to restore covered video scenes. It fails to handle rolling subtitles, floating text and multi-line embedded captions well. Many advanced caption hiding effects even need Canva Pro membership. Besides, it cannot keep original video quality perfectly after modification. AutoAGC has no such limits, free to use, restore video picture naturally without membership fee.
