The native audio and video generation part is honestly the biggest shift here. Most AI video tools still feel stitched together when it comes to dialogue, ambient sound, and lip sync.
What’s interesting is how this could impact AI UGC and ecommerce workflows too. I’ve been seeing platforms like Tagshop AI experimenting with scalable creator-style product videos recently, and models like Seedance 2.0 feel like the kind of backend leap that could make AI generated ads look way more natural.
The multi shot consistency is the real game changer though 👀
