In this video, I test the newly released Seedance 1.5 Pro. Honestly, it is by far the best video model right now when it comes to audio, speech, and lip-syncing. While models like Kling 2.6 and Veo 3.1 struggle with "sliding mouths" or robotic audio, Seedance 1.5 nails the mouth shapes frame-by-frame.
However, it’s not perfect. It is capped at 720p and struggles significantly with complex physics compared to the competition.
I put this model through a 3-part test: Cinematic Camera Motion, a direct Lip-Sync Battle against Kling & Veo, and a deep dive into my "First and Last Frame" workflow to generate consistent AI influencers that actually speak naturally.
Whether you’re a filmmaker or creating AI UGC ads, by the end of this video you’ll understand:
The strengths and weaknesses of Seedance 1.5 (Audio vs. Physics).
