Mastering AI Generative Video with Runway GEN 2 Motion Brush: A Step-by-Step Guide
Have you ever wondered if artificial intelligence can make the Mona Lisa smile? Well, wonder no more! Runway has just released its latest feature, the Motion Brush. This groundbreaking tool allows you to generate motion in your videos like never before. Let's dive into the world of AI video creation and see how the Motion Brush can bring your images to life!
Getting Started with Runway
First, open up your preferred web browser and go to RunwayML.com. If you're new to Runway, don't worry! There's a tutorial popping up on the top of the page to guide you through the process. Once you're familiar with the platform, log in and let's begin.
Using the Motion Brush Tool
To start using the Motion Brush, click on the "Start with Image" button. This will prompt a video generation prompt box with all the necessary tools. And now, the exciting part - Runway has just added the Motion Brush tool!
Upload the image or video you want to apply the Motion Brush to. For this tutorial, I'll be using a mean-looking, fiery metallic skull. Once your image or video is uploaded, click on the Motion Brush tool and unleash your creativity!
The canvas gives you full control of the Motion Brush. Up top, you can adjust the brush size and eraser size. On the bottom, there are three main directional speed controls - Horizontal, Vertical, and Proximity.
The Horizontal control determines the speed of motion from left to right, with a range of -10 (maximum motion speed to the left) to 10 (maximum motion speed to the right). The Vertical control works similarly, but for motion upwards or downwards. And the Proximity control adjusts how the motion moves towards or away from the camera.
Note that the brush tools and controls are quite sensitive, so it's best to loosely paint around the areas where you want to create motion. This will help you avoid wasting credits and ensure the best results.
For example, let's create a burning motion around the skull's head. I'll set the Vertical speed value to 6 and add a slight Proximity value. With a click of the "Generate" button, the fire comes to life, looking incredibly realistic. The Motion Brush does not disappoint!
Introducing the Camera Motion Tool
But wait, there's more! Runway has also added the Camera Motion tool, which allows you to apply additional camera movements to your video. This tool works independently of the Motion Brush, meaning you input the camera motion values separately.
Let's say you want to zoom in slightly and have the camera pan to the right. With the Camera Motion tool, you have the power to bring these actions to life. Simply adjust the values, save your settings, and hit "Generate."
However, use the Camera Motion tool with caution. It's easy to go overboard, so remember to keep it subtle and realistic. You don't want your viewers to feel dizzy!
Exploring Motion Speed Strength
Now, let's talk about motion speed strength. What if you want the motion to be faster or slower? Runway allows you to control the speed of motion to achieve your desired effect.
For horizontal motion speed, I've experimented with different values of 2, 6, and 10. As you can see, the higher the value, the faster the motion appears. Similarly, for vertical motion speed, I've used the same values. Not bad at all, right?
Creating Longer Videos
By default, the generated videos are limited to 4 seconds. But what if you want your video to be longer? Don't worry, I've got a pro tip for you!
After generating motion on your first video, you can download the video and visit Finalframe.net. This platform captures a snapshot of the last frame of your video, which you can then use to continue the motion on your first video.
Simply upload the Final Frame image to Runway, paint in your desired motion, adjust the speed values, and hit "Generate" once again. Now, you have the power to create longer videos with seamless motion transitions.
Remember, perfection takes time and experimentation. If your results aren't perfect on the first try, don't worry. Keep regenerated it and fine-tune until you achieve your desired effect. Once you're satisfied, you can combine the first video and the current video using your favorite video editor.
And voila! You're ready to show off your masterpiece to the world!
