Hedra AI Lip Sync (Free) - Make Characters Talk or Sing

Hedra is an AI tool with the ambition of doing various things, but right now, it's particularly excelling at lip sync. Here's a comprehensive look at how to get started and make the most out of this fantastic feature.

Getting Started

First, head over to the Hedra website and click the button that says "Try Beta." You'll then see another button labeled "Sign in to use," which appears to currently only support Google sign-ins. After selecting your Google account and completing the necessary confirmations, you'll be redirected back to Hedra, where you'll be asked to accept the terms of service and privacy policy. Note that residents of Illinois, Texas, or Washington are not permitted to use the services, and users must be over 18 years of age.

Using the Interface

After accepting the terms, navigate back to the homepage and again click "Try Beta." This will bring you to the generation screen with three panels: the audio panel on the left, the character panel in the middle, and the video/preview panel on the right.

Audio

In the audio panel, you have the option to generate audio by typing in text, selecting a voice from a dropdown menu, and letting it generate the speech. Alternatively, you can import audio that you've already created.

Character

For the character panel, you'll need a face to sync the audio with. You can either drag and drop an image, paste an image from your clipboard, or describe your character in a text box, and Hedra will generate an image for you.

Combining Elements

Once you have both the audio and character elements ready, click the "Generate Video" button to create your lip-synced video. The generation process takes some time, which has been sped up for demonstration purposes in the video.

Experimentation and Features

The video walks through several experiments, including generating audio within Hedra, importing custom audio from 11 Labs, and even creating a character image using Leonardo. The lip-sync quality is notable, with not just mouth movements but also head, eyes, and upper body movements to match the audio.

Additional Options

  • Report Issues: The three dots icon on the preview panel offers options to report copyright issues or unacceptable content.
  • Sharing: You can toggle a link for sharing the video and copy the URL for distribution.
  • Settings: In the character creation panel, there are options for adding negative prompts, using a manual seed, and auto-cropping images.

Advanced Experiment

One of the unique experiments involved using AI-generated music to see if a character could lip-sync to a song. An Abraham Lincoln character was generated to sing a blues song—demonstrating the flexibility and creative potential of the tool.

Conclusion

Hedra is currently free and offers unlimited usage with a watermark on output videos. It only supports a square resolution format for now. Despite these limitations, the quality of lip syncing—incorporating full facial and upper body movements—is impressive.
