Seedance 1.5 Pro

Dubbed video usually means generating footage, recording audio and then fixing mouths that no longer match the words.

Seedance 1.5 Pro is an AI video generator that produces picture and sound together, so speech and lip movement are synchronized from the start.

It handles text to video and image to video, and its lip-sync covers multiple languages and dialects, which makes it relevant for AI dubbing work as well as original clips.

Under the hood, Seedance 1.5 Pro uses a dual-branch Diffusion Transformer with cross-modal joint modules.

Training combined Supervised Fine-Tuning with Reinforcement Learning from Human Feedback, aimed at better narrative coherence and cinematic output.

It also offers camera control for dynamic shots, and inference runs over 10 times faster than before, a claim worth testing against your own clips.

The platform is pitched at professional content creators who need to produce at volume and publish across different distribution channels.

Pricing is not something to count on here, so check the site before planning a workflow.
