Bring still images to life and learn how to create a living portrait in Runway.

Step 1: Brush out and replace the parts of your image you'd like to change using either Erase & Replace or Infinite Image.
Step 2: Head over to Frame Interpolation to animate your various images into a video.
Step 3: Behold the beauty of your new living image.


Create a Living Portrait

Learn how to seamlessly transition images into one another by using our Frame Interpolation AI Tool.

- Frame Interpolation works well to create videos with subtle movement from still images
- The more frames you have to work with, the better
- Keep the differences between photos subtle if possible for realistic effect
- Try using Erase and Replace to create new images to interpolate between!


Frame Interpolation

- Backdrop Remix changes the background of your photos while keeping the subject in tact
- Upload your photo, and choose a preset or a custom prompt
- Click “Generate,” and Runway will get to work replacing the background automatically — that’s it!


Backdrop Remix

Use this lesson to learn tips and tricks for using Text to Color Grade.

- The main thing to keep in mind: you can never go wrong with natural language.
- Typing in a movie title alone might be counterproductive sometimes; add in a description to make the movie title interpretation less literal.
- Same goes for specific film stocks — add additional descriptors.
- Try different seed numbers for different options.


Text to Color Grade

- Find Infinite Image in the AI Tools section. Start with a text prompt to generate an original image, or upload your own image.
- Move the generation frame to desired area. Make sure it’s overlapping the original image!
- Be descriptive with your text prompt and click “Generate.” You’ll then be presented with 4 initial generated options to choose from.
- Repeat this process as many times as you’d like to continue extending your image.
- Use adjustment button to adjust prompt weight; lower for more surprising and creative results, higher to stay more true to the prompt.
- Try opening your final image in Erase and Replace to clean up any elements in your image you’d like to change.


Infinite Image

Learn how to create generative images using various AI Tools.

- Learn how to create a generative image using AI Tools
- AI Tools used:
    - Text to Image: creates an original generated image from a text-based prompt
    - Erase and Replace: eliminates a specific part of an image and replaces it seamlessly with a new image generated from a new text based prompt
    - Image to Image: uses an image as the input, and generates a brand new image based on both the original and a descriptive text based prompt
- When writing prompts, be descriptive. Include object colors, orientations, and artistic styles in your prompt.
- Refine as you go — the initial output does not have to be perfect. You can slowly work and refine your image with tools like Erase and Replace and Image to Image to gradually get your content to where you want it.

Getting Started

Learn how to use Text to Image for use with Gen-2 in Runway.

- Open Text to Image and explore the newly updated styles in the “Advanced” menu
- Customize output with mediums and moods
- A notable mention is the “Cinematic” style — adept at crafting photorealistic, cinematic visuals
- Once you have a generation you like, navigate over to Gen-2, and use the image as your prompt
- Before generating, open the advanced camera controls to set the direction and intensity of motion in your video


Image to Video Workflow

Gen-2

Learn how to use Generative Audio to add speech to your images and videos.

- Find Generative Audio on the Runway dashboard
- At the top, you’ll find an area to write anything you want and turn it into a spoken audio file
- After you type out your text, you can preview and choose voices from the default voice menu
- Once you choose a voice, click on the “Generate” button
- Generate times depend on script length, but are generally pretty quick
- Audio generations are automatically saved to the “Generative Audio” folder inside of the main assets folder, but can be saved elsewhere
- Custom Voice training only requires a few minutes of clean audio with no background noise — import or record in Runway
- Finally, to create a Lip Sync video, you’ll need a video or image of a person whose face is fully in the frame
    - upload your own or use one of the characters in the list
    - Lip Sync can be used with generated audio from Text to Speech, recorded audio or uploaded audio
    - choose a voice and click “Generate”
- Tip: turn your image into a video with Gen-2, then upload that video into the Generative Audio tool to add Lip Sync to your video
- If your audio is longer than your video, once your video reaches the end of its duration, it will reverse and go back to the beginning for the duration of the audio
    - avoid using general camera motion controls and instead use Motion Brush, which makes the reverse effect less noticeable

Learn how to generate using Styles in Frames.

- Enter a Generative Session, then click on the paint palette icon to access Styles
- Click on any Style to activate it, then enter a prompt into the prompt box
- Simple and long prompts both work well with Styles, with primary focus on the subject and environment
- Choose an aspect ratio, then click “Generate”
- To see the prompt that was used for any of the Styles, click on the top right corner of any of the Styles thumbnails
    - This is helpful to learn what prompt modifiers are being used to create the Style
- To create your own Style, click on “Create,” give it a name, and write the prompt in the prompt box
    - Creating your own Style is a fast and easy way to create images that are in the same stylistic universe, without the need to type the same prompt structure over and over again
    - Focus on stylistic elements (color tones, lighting, shadows, textures, etc.) and avoid things that are too specific, like subject or location details to ensure your Style works for a wide variety of prompts
    - For specific location Styles, be as descriptive and detailed as possible
- Try using Aesthetic Range with Styles to continue exploring new ideas and environments


Using Styles in Frames

Learn how to generate images with Frames.

- Open a Generative Session and select the “Image” tab
- Choose aspect ratio, then start prompting
- To get the most out of Frames, it’s helpful to structure your prompt with the following format: [art style] [subject] [scene] [lighting] [color]
    - For example: A cinematic photo of a peacock in the water. The lighting is even, creating subtle shadows, with a muted natural color palette.
- Within each section of the prompt, you can keep descriptions general or choose to get more granular for more specific results
- It’s not necessary to include all of these categories every time - Frames does well understanding simple prompts as well
- Experiment with Aesthetic Range, which allows you to dial up and down the overall creative variation that you’ll see across a set of four generations
    - Lower values will remain stylistically close to the original prompt, with minimal changes to camera angles, lighting and color grading
    - Higher values will introduce more extreme stylistic changes to your image while keeping your subject the same
- Once you’ve generated images, you can download, favorite or click the “vary” button to generate four more similar images
- Click the “Use” button to swap the Generative Session UI into video mode, using the Frames output as an Image to Video input
- Check out [runwayml.com/worlds-of-frames](http://runwayml.com/worlds-of-frames) for inspiration


Generating with Frames

Frames

Learn how to use a restyled first frame for more control with Video to Video.

- Inside of a Generative Session, choose a video you’d like to stylize
- Click on “Styled first frame” icon
    - From here, you can download the first frame of your original video to apply stylization to it
    - During the stylization process, make sure the image dimensions remain the same
- Upload the styled frame into Video to Video
- Add a text prompt for additional context if you want, then click “Generate”
- Default Structure Transformation is set to 3, but try experimenting with different values to get different video motion results
- You can even try adding or changing elements from the original frame instead of completely restyling it, to turn Video to Video into a VFX engine
- If you feel like getting experimental, you can upload a completely different image than the first frame, which will give you unexpected and interesting results
    - For this method, increasing the Structure Transformation above 5 is typically helpful for getting better looking videos


Using Restyled First Frame

Learn how to use Character Reference Videos in Act-One.

- Head to Generative Sessions tool and open up Act-One in Gen-3 Alpha or Gen-3 Alpha Turbo
- You can now use a video as your character input, in addition to images
- Upload or record your driving performance, choose a video clip for your character reference video, adjust motion intensity if you’d like, and hit “Generate”
- Keep in mind: if your driving performance video is longer than your character reference video, the output will automatically reverse at the end of the clip to fill the duration
- Character reference videos in Act-One can be live action videos, giving you the freedom and flexibility of changing performances in post
- You can also bring in your Gen-3 Alpha videos as character videos, giving your generative workflows a huge boost in expressiveness
- You can even run your video clips through Video to Video before bringing them into Act-One to completely control every aspect of your performance


Character Videos in Act-One

Learn how to use Expand Video in Gen-3 Alpha Turbo.

- Expand Video allows you to seamlessly generate beyond the edges of a frame to turn horizontal videos into vertical videos, and vice versa - without compromising details or framing
- Open Gen-3 Alpha Turbo to use Expand Video
- If you upload a horizontal video, the model will automatically default into turning it into a vertical video
- You’ll have a few options:
    - Click the Generate button without providing a text prompt
    - Provide a detailed text prompt telling the model what you’re hoping to see in the parts of the frame that aren’t visible
    - Provide the model with an outpainted image of the first frame of your video
- Best practices:
    - Subject is close to center of the frame
    - No graphics or text present in the video
    - Use a guiding text prompt
- If you run multiple expansions in a row, you can create wide shots of the scene — then by overlaying the original footage onto the expanded canvas, you can create super zooms


Gen-3 Alpha Expand Video

Learn how to use Camera Control in Gen-3 Alpha Turbo.

- Head to Generative Video, then Gen-3 Alpha Turbo and upload an image
- Camera Control allows you to plan out specific camera movements for your scene: left/right, up/down, in/out, pan left/right, tilt up/down, rotate clockwise/counter-clockwise
- The camera speed is determined by how close your subject is to the camera
    - Use smaller values when your subject is closer and larger values when your subject is far away
- Camera Control will generally work better if you provide a text prompt to help guide your generation (example: where you want the camera to move, what you want your subject to be doing, add more to the scene)
- Try using presets for inspiration, found underneath the prompt box


Gen-3 Alpha Camera Control

Learn how to use Act-One to generate expressive performances using a single driving video and character image.

- Head into Generative Video with Gen-3 Alpha selected
- Click “Act-One” icon on the left sidebar
- Add your source footage
    - Act-One can work with characters positioned at varying angles as long as it’s not too extreme
    - Maintain lively facial expressions with the entire face in view, with minimal body movement and clear audio
- Add your reference image
    - Upload your own image or choose from one of our presets
- Once ready, hit “Generate”
    - Your result will be a seamless animation preserving all of the subtle expressions and movements from your performance, but transposed onto the character from your reference image


Getting Started with Act-One

Learn how to use Video to Video in Gen-3 Alpha.

- Open up Generative Video and select Gen-3 Alpha
- Upload a source video
    - input videos 5s or less cost 50 credits, input videos longer than 5s (up to 10s) cost 100 credits
- Add a text prompt describing how you’d like to stylize your video
- Adjust structure transformation slider in settings
    - lower values will adhere to the source video structure more
    - higher values will allow you to slightly deviate from structure of input video
- Click “Generate”
- Use custom style presets to experiment with new styles
    - edit the purple text in the text prompt with a quick description of your scene


Gen-3 Alpha Video to Video

Learn how to extend Gen-3 Alpha generations.

- Choose Gen-3 Alpha from the model dropdown in the Text/Image to Video tool (extensions aren’t available in Gen-3 Alpha Turbo yet)
- Generate a video from a text prompt or an image
- Click “Extend” — choose to extend it by 5s or 10s for a maximum of three extensions total
- If you click the “Extend” button with no additional prompt, Gen-3 Alpha will automatically continue the motion from the previous video
- If you’d like, you can add a text prompt to your extension for more control, or to add something new
- From your assets folder, you can always navigate back to a previous Gen-3 Alpha generation and extend it from there
- Extensions are a great way to get more out of Gen-3 Alpha — showcasing the environment, transitioning the scene or just continuing the action


Gen-3 Alpha Extensions

Learn how to blend live action video with Generative Visual Effects.

- Find or shoot a source video
    - Suggested camera settings: auto focus off, auto white balance off, camera on tripod
- Next, scrub through your footage and export a still image from where you want to add visual effects
- Bring the still image into Gen-3 Alpha Image to Video
- Depending on your idea, you can choose to input the image as the first frame or last frame
- In this example, we’ll select the first frame and add a text prompt describing the effect
- Once you have a shot you like, composite (combine two or more images together to make one final image) the source video with the generated video
- For the final output, feel free to add color correction or masking if needed
- Gen-3 Alpha Image to Video allows you to achieve various levels of VFX — from singular assets to fully blended live action and generated content

Learn how to use Text to Video with Runway’s newest video model, Gen-3 Alpha.

- Head to Text/Image to Video tool and select Gen-3 Alpha from the model dropdown
- Add a text prompt
- Select 5s or 10s video to generate
- 720p generations take about 60s for a 5s video, or 90s for a 10s video
- The more detailed you can make the text prompt, the more Gen-3 Alpha will shine
    - Include things like subject, scene, lighting, camera, movements and more
- In addition to visual details, Gen-3 Alpha can be prompted for subject action, camera action, speed, transition and more
- Gen-3 Alpha works with a wide variety of prompt structures, from super simple to more complex
- If you’re looking for inspiration, separate prompt into a visual description and a camera description
    - Example: Visual: A pillow fort in a cozy living room. The pillow fort is made from an assortment of quilts, fabrics and pillows Camera motion: Hand held camera smoothly zooms into the entrance of the pillow fort, revealing an ancient castle in the interior

Learn how to use References in Gen-4 for consistent characters, locations and more.

- Gen-4 References allows you to visualize and create consistent characters and locations, new shots and angles and so much more
- Open a new Session and click on the “Image” tab
- Drag in up to 3 Reference images to use
- If you’d like to save a Reference into your library for a quick recall later, hover over the Reference image to give it a name
    - Use Saved References by using the @ command in your text prompt
- Be conversational with your prompts - ask for new angles or characters
- Choose any part of the image to reference - lighting, color grading, compositions, poses and more
- Reference different images directly by using tags/saved References, or simply reference “image 1” or “image 2” in your prompts according to the upload order of your images
- Currently, References primarily supports character and location preservation, but we will be making updates in the future to support objects, styles and more


Gen-4 References

- Open a Generative Session and make sure that Gen-4 is selected from them model dropdown
- Upload an image to use it as the first frame of your video
- Gen-4 supports Image to Video with multiple aspect ratios and will automatically adhere to the closest aspect ratio to your image, but feel free to change it
- Providing a text prompt with your image provides more control of your scene and camera
- Prompting should focus on the things you want to happen in the video, specifically the subject action and camera action
- Or, you can use Gen-4 with no prompts at all for stunning results
- Gen-4 works well in a visual effects workflow, prompting for scene actions to take place, or by animating visual effects assets that can be used in a more traditional compositing workflow
- Don’t forget to combine Runway workflows and models together, like Act-One to make your characters speak, or Expand Video to see more of your scene, run your outputs through Video to Video to reimagine them, or upscale your videos to 4K for higher fidelity
