How are creators making dolls lip-sync videos longer than 15 seconds? Looking for workflow/tool advice.

Hey everyone,

​

I’ve been seeing a lot of creators on Instagram posting these really impressive AI videos of Barbie dolls lip-syncing to songs.

​

Most of these clips used to be under 15 seconds, which makes sense since tools like Kling AI or Google Omni have strict duration limits. However, lately, I’ve been noticing some creators breaking this barrier, putting out videos that run for 25 to 30 seconds with perfect lip-syncing and clean camera motion control. Crucially, there are no visible cuts or abrupt transitions in the middle.

​

Since the mainstream video generators cap out at 15 seconds, I’m trying to figure out the technical workflow behind this.

​

​

- Is there a specific pipeline (like ComfyUI with AnimateDiff or LivePortrait) that allows for longer, continuous motion control without melting the prompt coherence?

​

If anyone is making this type of content or knows the current state-of-the-art workflow for bypassing those short duration limits, I’d love to know your secrets.

​

Thanks in advance!
