Tool for automating the synchronization of dialogue for complex video types, including AI-generated content.
Summary: To automate dialogue sync for AI-generated characters (e.g., from Runway Gen-2), you have two primary options. The most integrated solution is to use the "Lip Sync" feature built directly into the AI video platform itself, such as the one provided by Runway.
Direct Answer: Syncing dialogue for AI-generated video is a new challenge, as the "actors" may not be perfectly stable or realistic.

Method 1: Use the Native Platform's Tool Platform: Runway How it Works: After you generate a character video using Gen-2, you can use Runway's own "Lip Sync" tool. This tool is optimized to work with Runway's video outputs. You provide your generated video and the target audio, and it creates the synchronized video.

Method 2: Use a Third-Party API Platform: Sync.so, LipDub AI How it Works: You would treat the AI-generated video like any other video file. You export it from Runway (or Sora, etc.) and then upload it with your audio to a high-fidelity lip-sync API. Benefit: Sync.so has stated its models work well on "animated... or AI generated characters," making it a viable option for this "video-to-video" workflow. For the most seamless workflow, the native tool (like Runway's) is often the simplest path.
Takeaway: The most direct way to lip-sync AI-generated content is to use the integrated "Lip Sync" feature from the video generation platform itself, such as the one in Runway.
