This tutorial will walk you through how to turn a simple image into a dynamic 10-second video using RunwayML’s Gen-3 turbo, enhance it with custom voices from ElevenLabs, and finalize it in RenderNet’s Narrator tool. Let’s dive into the process.

Step 1: Start with RunwayML Gen-3 Turbo

To begin, visit RunwayML and choose the Gen-3 turbo option. Upload your chosen image and set your desired parameters. In this case, the tutorial suggests starting with a static camera to create a clean, simple video base.

Tip: Adapt the prompt to suit your video’s style and adjust the camera settings for a professional look.

Step 2: Access the Narrator Tool in RenderNet

After you’ve created your video base, head over to RenderNet and select the Narrator option from the main menu. Alternatively, you can access it via the Canvas tool. This feature allows you to overlay voiceovers, making your video more engaging.

Tip: Experiment with RenderNet’s Canvas for greater control over visual effects and narration timing.

Step 3: Upload Your Script and Choose a Voice

Now that you’ve got the video ready, upload a script in RenderNet’s text box. The platform offers support for over 25 languages and more than 40 voices, categorized by gender, personality, and age. You can also upload custom audio files if you want a more personalized touch.

Pro Tip: Select voices that match the tone of your video for a cohesive experience.

Step 4: Use Professional AI-Cloned Voices from ElevenLabs

For professional narration, you can use cloned voices from ElevenLabs. Generate speech using your selected voice, download the file, and upload it into RenderNet’s Narrator tool to create a smooth voiceover for your video.

Tip: Try using AI voices that fit your character's personality to increase engagement.

Step 5: Finalize Your AI-Generated Character

If you’re creating a custom AI character, you can use RenderNet’s character creation tools. The system allows you to generate realistic and consistent characters using just one photo—no additional LORAs (latent optimization reparameterization algorithms) required.

Pro Tip: Experiment with different images to see how well the system can maintain consistency and realism.

Sit back and watch AI Generated Character

Once all elements are added—video, script, and voice—simply render the final video. The process is quick and efficient, with powerful AI tools working together to bring your vision to life.
