Runway

Runway is one of the leading AI video platforms. You can generate clips with its Gen-4.5 model, edit existing footage with Aleph 2.0, and use models from other companies in the same app. Let's learn the current workflow.

Older models such as Gen-3 Alpha have been retired, so older tutorials may show buttons and settings you won't find today.

What Makes Runway Special

Runway stands out for:

• Creative control: Gen-4.5 follows detailed directions about the subject, the action, and the camera
• Motion: Strong at realistic movement and physics
• Editing: Aleph 2.0 changes existing video without starting over
• Choice of models: Runway also hosts models from other companies, such as Kling and Seedance
• One workspace: Generate, edit, and export in one place

Runway is a strong option, but no single tool wins every shot. Compare it with the other leading models before you choose.

Getting Started with Runway

Creating an Account

1. Visit runway.com
2. Sign up with email or Google
3. You get 125 free credits, one time only. That is about 10 seconds of Gen-4.5 video, and the free plan may limit which models you can use
4. Paid plans start at $12 to $15 per month for 625 credits. Check the pricing page before you subscribe, because plans change often

Gen-4.5 Settings

Setting	Options
Input	Text prompt, or an image plus a prompt
Duration	2 to 10 seconds
Aspect ratio	16:9, 9:16, 1:1, 4:3, 3:4, 21:9

Text-to-Video in Runway

Basic Generation

1. Choose Gen-4.5 as your model
2. Enter your prompt
3. Select the duration
4. Choose the aspect ratio
5. Generate and review the result

Writing Effective Runway Prompts

Runway responds well to structured prompts:

[Subject description], [action/motion], [environment],
[camera motion], [lighting], [style keywords]

Example prompts that work well:

A woman with flowing red hair walks through a neon-lit
Tokyo street at night, tracking shot following her,
cinematic, rain reflections on the ground

Close-up of coffee being poured into a white ceramic cup,
steam rising, soft morning light through a window,
slow motion, shallow depth of field

Drone shot rising above misty mountains at sunrise,
layers of fog between peaks, epic cinematic,
golden hour lighting

If your prompt has several actions in a row, choose a longer duration so each one has time to happen.

Directing the Camera

With Gen-4.5, you direct the camera in your prompt. Use the words a film crew would use:

• Push in / Pull out
• Pan left / Pan right
• Tilt up / Tilt down
• Orbit left / Orbit right
• Crane up / Crane down
• Tracking shot / Handheld / Static shot

Combine Motions

You can describe more than one camera move. For example:

• "The camera pushes in and tilts up" gives a rising, dramatic reveal
• "The camera pans right and pulls out" opens up the scene

Control the Intensity

Use plain words to set how strong the movement is:

• Subtle: "a slow, gentle drift"
• Medium: "a steady push in"
• Strong: "a fast, sweeping orbit"

Older Runway models had separate camera sliders and a Motion Brush. You may still see tools like these on some models in the app, but don't count on them with Gen-4.5. If a control isn't there, write the direction in your prompt.

Image-to-Video in Runway

Starting from an image gives you more control over the look of the shot.

Preparing Your Image

• Resolution: Use a clear, high-quality image
• Composition: Consider what will move and how
• Style: The video inherits the image's style
• Aspect ratio: The video follows your image unless you change it, which crops the image

Writing the Prompt

Drag your image into the prompt window. The model can already see the image, so don't describe it again. Describe only what should move:

The camera slowly pushes in as the waves roll toward
the shore and the clouds drift to the left

What works well:

• Landscapes with sky or water
• Portraits with subtle expression changes
• Scenes with clear motion potential

What's challenging:

• Complex human poses
• Multiple moving subjects
• Text-heavy images

Editing Video with Aleph 2.0

Aleph 2.0 is Runway's video editing model. Instead of generating a new clip, it changes footage you already have. Edit one frame, and the change carries through the rest of the video while other elements stay the same.

You can use it to:

• Change the style or the lighting of a shot
• Swap or remove objects
• Apply the same edit across several cuts

It handles clips up to 30 seconds at 1080p and is available on paid plans.

Tips for Better Results

Do's

• Be specific about motion: "slowly walking" vs "walking"
• Include lighting info: It dramatically affects mood
• Use camera terms: Runway understands film language
• Specify what moves: "The camera pushes in while the subject remains still"
• Iterate: Use a good frame as the image input for your next try

Don'ts

• Avoid conflicting motion: Don't ask for static and dynamic at the same time
• Don't expect a long story in one clip: Gen-4.5 clips run up to 10 seconds
• Avoid tiny details: Small text and small objects often don't generate well
• Don't overload prompts: Focus on key elements

Credit Management

Runway charges credits per second of video, and the rate depends on the model:

Model	Cost	5 seconds	10 seconds
Gen-4.5	12 credits per second	60 credits	120 credits
Aleph 2.0 (editing)	28 credits per second	140 credits	280 credits

Gen-4 Turbo costs about half as much as Gen-4.5 and is faster, so it's useful for testing ideas. Rates change, so check the credit cost shown in the app before you generate.

On the 625-credit plan, you get about 52 seconds of Gen-4.5 video a month. Failed experiments use up that total too.

Tips to conserve credits:

• Test prompts with short clips first
• Try ideas on a cheaper model, then make the final version on Gen-4.5
• Save successful prompts for reuse

Example Workflow

Here's a complete workflow for creating a cinematic shot:

1. Write initial prompt:

   A lone astronaut standing on Mars, looking at Earth
   in the sky, dust particles floating, cinematic, epic scale
   

2. Generate a short test

3. Evaluate and refine:

   • Too static? Describe the movement you want
   • Camera too still? Add a camera move to the prompt
   • Style off? Add more style keywords

4. Generate the final 10-second version

5. Edit if needed with Aleph 2.0, or combine several clips in your editor for a longer sequence

Key Takeaway

Runway gives you strong creative control through clear prompts, and Aleph 2.0 lets you edit footage you already have. Direct the camera with film language, check credit costs before you generate, and iterate based on results. In the next lesson, we'll explore Pika as a complementary creative tool.
