Runway Gen-3 Image-to-Video Ai is Here! - Comparison with Luma & Kling - Tutorial

Introduction

Runway Gen-3 recently released their AI-powered image-to-video generator, adding to their suite of innovative tools for AI video creation like the motion brush. While the anticipation for Gen-3 was high, my hands-on experience left me somewhat underwhelmed. Here’s a detailed breakdown of why it fell short in my tests.

Testing the Gen-3 Model

I logged into Runway and accessed the video generation interface, ensuring I selected the Gen-3 Model. The interface is straightforward—just drag and drop an image, optionally add a prompt, and choose between a 10-second or 5-second video. The video generation process is quick, taking only a few minutes.

Issues with Facial Structure and Color Grading

I started with an image featuring nice pastel colors. Despite decent camera motion, I noticed inconsistencies. The facial structure of the character changed from a young woman to an older lady. The color grading varied from muted, dim colors to bright, saturated pinks—a recurring issue in Gen-3.

Sample Videos and Prompts

• Boy Wizard Animation: The animation wasn’t terrible; it zoomed in but lacked real 3D movement. The magic spell appeared to come from his fist instead of the wand.
• Swimming Turtle: Nature videos turned out well. The turtle's swimming motion was dynamic, and the camera work was commendable, although colors got brighter.
• Complex Prompts: A prompt asking for a robot to transform into an attractive woman resulted in a static figure that wasn't useful. Simplified prompts, like a robot just walking, showed better motion but unrealistic rain effects.

Consistently Good Results

Some specific types of cinematic, muted-color-tone videos worked well. For instance, a 10-second video of a man and a woman playing chess remained consistent, with great details and minimal issues.

Common Issues and Limitations

Common problems include switching scenes mid-clip and a limitation that forces the cropping of high-resolution images before running them through the AI video generator. This limitation does not exist on other platforms and proves to be an inconvenience.

Comparative Analysis

To give Gen-3 a fair assessment, I compared it with Luma AI and Kling AI.

Luma AI

• Astronaut Example: Gen-3 had a peculiar issue of animating astronauts walking backward, with a notably twisted head. Luma's video got blurry but was more coherent.
• General Performance: Gen-3 handled facial consistency and motion well, though it added brighter colors. In some cases like robot cinematics, Gen-3 outperformed Luma by maintaining a more consistent 3D style.

Kling AI

• Comparable Outcomes: Gen-3 created videos of floating flowers that looked appealing. The robot sliding down the road was equally good in both generators.
• Dynamic Motion: Kling had more dynamic motion for certain clips, whereas Gen-3 sometimes resulted in videos with minimal animation, often just zooming in on a static photo.

Conclusion

Gen-3 indeed has innovative potential, and while it excels in some areas, it currently falls behind Luma AI and Kling AI, especially considering its pricing. However, with future updates, including the reintroduction of camera controls and motion brush, there is hope for improvement.
