Mind-blowing physics in Wan 2.1 video model - reflections, weight & motion

Wan 2.1 Takes Physics to the Next Level 🎥 In this video, we explore how the Wan AI image-to-video model handles physics with surprising accuracy - from a giraffe's weight bending a tree to realistic reflections in sunglasses. The model also keeps separate entities, like fish, consistent without weird morphing. It’s not perfect yet (the juggling example almost works), but the way it manages physics, detailed features, and consistency is pretty impressive. Check out the breakdown to see what makes this model so cool! ⏱️ TIMESTAMPS ⏱️ 00:00 - Intro: Wan AI video model examples 00:30 - Intricate details: Hands and fingers 01:01 - Image-to-video: Drawing becomes animated 01:35 - Realistic physics: Giraffe weight & tree bend 02:13 - Facial expressions and hairstyle changes 03:19 - Complex juggling: AI almost gets it right 03:54 - Reflections: Sunglasses in the mirror 04:56 - Staying separated: Fish don’t morph 05:37 - Final thoughts: Seriously cool model ability Try it out here: https://replicate.com/wan-video https://replicate.com/wavespeedai
