Creating Long AI-Generated Videos with Consistent Characters Using Grok AI

This tutorial demonstrates how to create long AI-generated videos featuring consistent characters using Grok AI, a free and unlimited tool available on both desktop and mobile devices. The process involves several key technological steps and product features.

Key Technological Concepts & Features

1. Story Generation

Use AI text generators such as ChatGPT or Google Gemini to create a story script.
The example uses Gemini to generate a Disney-style short story with two characters, approximately 60 seconds long.
Gemini also produces visual prompts linked to the story. For a 1-minute video, 12 prompts are needed since Grok generates 5-second clips.

2. Visual Content Creation with Grok AI

Grok offers two modes:
- Image generation from text prompts.
- Video generation from text prompts.
Users input visual prompts to generate images, then animate them into 5-second video clips.
Supports various aspect ratios to fit different platforms.
The tool is free and unlimited in usage.

3. Maintaining Character Consistency

Generating each frame from separate prompts leads to inconsistent characters and unnatural transitions.
The key technique:
- Copy the last video frame of the previous clip and paste it into Grok’s prompt bar before adding the next visual prompt.
- This uses the last frame as a reference to generate the next clip, ensuring smooth transitions and consistent characters.
Toggle between image and video modes appropriately to guide Grok’s generation.
Disable the “enable automatic video generation” setting to prevent unwanted auto-generation after pasting frames.

4. Video Editing and Assembly

Download all clips and import them into a video editor like CapCut.
Arrange clips according to the story and synchronize them with the voiceover.
Extract audio from clips and lower its volume to serve as background noise.
Adjust the video aspect ratio to 9:16 (ideal for TikTok/shorts), scaling clips to fill the screen properly.

5. Voiceover Generation

Use Google AI Studio’s text-to-speech with Gemini, another free and unlimited tool.
Choose from multiple voice models to find the best fit.
Paste the entire story script to generate a high-quality voiceover.
Edit and clean the audio track by removing silences or unwanted gaps.

6. Captions and Final Touches

Combine all voiceover clips into a compound clip in CapCut.
Generate automatic captions using CapCut’s text tab.
Customize captions with animations, fonts, and styles.
Add manual transitions between clips for smoother flow.
Export the final video.
