A frontier video generation model developed by Runway: creates cinematic videos with consistent characters and objects.
Top choice for creating professional-quality videos with consistent subjects and movie-like camera work. Perfect when visual consistency matters most.
Character consistency: Maintains the same person, product, or mascot across different scenes and lighting conditions.
Product consistency: Place any product in multiple environments while keeping it visually identical.
Cinematic quality: Professional camera movements and scene control that rivals traditional filmmaking.
Scenarios where you have a specific visual you want to animate consistently:
Product videos: Show a product in various lifestyle settings with perfect consistency.
Campaign variations: Generate multiple scenarios with the same products for performance testing.
Mascot animation: Create consistent spokespersons or mascots across multiple video assets.
Requires a starting image (can't generate from text alone)
Struggles with overly complex multi-element scenes
Occasional visual glitches or hallucinations
More expensive than simpler animation models
Gen-4 thrives on simplicity and focus. Start simple and build up gradually:
Basic motion: "The subject turns slowly"
Add camera: "The subject turns slowly as camera circles around"
Add environment: "The subject turns slowly as camera circles, dust swirling"
Add style: "The subject turns slowly as camera circles, dust swirling, cinematic"
Pro tips:
Focus only on motion - let the image handle the visuals
Use "the subject" or "the product" instead of specific names
Say what should happen, never what shouldn't
Add one new element at a time when iterating
"The subject turns slowly toward the camera and smiles"
"The product rotates gently while the camera circles around it"
"She raises her hand and waves at the camera"
"The camera slowly pulls back to reveal the full scene"
"The person on the left walks forward. The person on the right waves."
