A: These sites ask you to paste a video URL. They return a heavily compressed, watermarked, or corrupted file. Many also harvest your search history and insert affiliate cookies. Avoid them completely.

A: No. Any extension claiming to do so is a scam. Chrome extensions cannot re-render video content on the server side; they can only modify CSS or DOM elements, which doesn't affect the actual video frames.

Bottom line: There is no secret backdoor. Any site claiming to offer free, watermark-free Shutterstock videos is lying to you.
