Text-to-Video

Gen-3 Alpha is the core function of Runway, which generates high-quality videos through text descriptions.

Scenario

Generate product advertising videos

Prompt example 
In Runway Gen-3 enter:




A sleek black smartphone slowly rotating on a white marble surface,


dramatic studio lighting from above, water droplets on the screen,


close-up macro shot, cinematic quality, 4K, slow motion
Output / what to expect

Generate high-quality 4-10 second product videos:

  • The phone rotates slowly, and the light illuminates the metal texture

  • The details of water droplets are clear and have a high-end advertising texture

  • Suitable for direct use in e-commerce or social media advertising

Tips

English prompt is better than Chinese. Add keywords such as "cinematic", "4K", and "slow motion" to improve quality. Video length is optional 4 seconds or 10 seconds (10 seconds requires more points).

Scenario

Generate time-lapse video of natural scenery

Prompt example 
Aerial view of a misty mountain valley at sunrise,


golden light slowly illuminating the peaks,


clouds moving through the valleys,


timelapse style, epic landscape photography,


National Geographic quality
Output / what to expect

Generate a spectacular valley sunrise time-lapse video:

  • Clouds and mist flow across the valley

  • Golden light gradually illuminates the mountain peaks

  • Suitable as video background or nature documentary material

Tips

Describe light changes ("slowly illuminating") and movement directions to make the video more dynamic.

Image-to-Video

Upload a picture and Runway can "animate" the picture and generate a coherent video.

Scenario

Make product images move

Prompt example 
Upload product static images in Motion Brush:




1. Use a paintbrush to paint the area you want to move (such as the product
body)


2. Set the movement direction: move slowly to the right


3. Enter in the text box:


"Product gently floating, soft ambient light, luxury advertisement style"
Output / what to expect

Product pictures turn into dynamic videos:

  • The product slowly floats and rotates

  • Light changes naturally with movement

  • The background remains static and the subject stands out

  • Suitable for e-commerce main image videos and circle of friends ads

Tips

Motion Brush can precisely control which areas move and which remain stationary, with more precision than pure text descriptions.

Video editing features

Runway is not only a generation tool, but also has powerful video editing capabilities.

Scenario

Remove video background with one click

Prompt example 
Upload the video to Runway and select the "Remove Background" tool:




1. Upload videos containing people


2. Click "Remove Background"


3. Select replacement background (solid color/picture/other video)


4. Export
Output / what to expect

Automatically identify and remove video background, the effect is comparable to professional green screen shooting:

  • Delicate hair edge processing

  • People in motion can also be accurately identified

  • Can be replaced with any background

  • Suitable for producing virtual background videos and live broadcast materials

Tips

Wearing clothes that contrast clearly with the background when shooting will result in better background removal.
