This is what GPT said:
I can make an educated guess, but it’s not 100% reliable. There are some common signs that suggest a video might be AI-generated, like:
• Strange facial expressions or unnatural movements.
• Weird lip sync issues where the mouth doesn’t match speech.
• Overly smooth skin or unnatural textures.
• Consistent lighting or shadows that don’t change naturally.
• Glitches, like hands not looking right or objects morphing.
• Perfect, too-scripted speech that lacks natural stumbles or filler words.
• Unusual eye contact where the subject either stares too much or their gaze doesn’t track properly.
If you want, you can show me a video (or screenshots from it), and I can tell you what stands out.
All those weird cabinets, floors, counter tops that have those motion images look fake.
