Prompt to clip
Generate a short cinematic shot from a written description alone using text-to-video.
Animate a still

Vertical and wide
Produce 16:9 widescreen or 9:16 vertical video at 720p or 1080p for different placements.
Points forts

- Outputs full-HD 1080p in addition to 720p for sharper, deliverable clips
- Built on the Runway Gen-4 family for high-fidelity, temporally coherent motion
Compromis
- 1080p is limited to 5-second clips; 10-second duration is only available at 720p

- Maximum clip length is 10 seconds and no audio is generated
En un coup d'œil
À propos de Runway
Runway is a video generation model built on the Runway Gen-4 family, available on HexGen for turning written prompts and still images into short, motion-rich clips. Write a description and it runs text-to-video from the prompt alone. Add a single start image and it switches to image-to-video, animating your frame into a moving shot.
The model outputs at 720p or full-HD 1080p in either 16:9 widescreen or 9:16 vertical, so you can target both landscape players and mobile-first feeds. Clips come back as MP4 files at 5 or 10 seconds, with the Gen-4 architecture delivering high-fidelity, temporally coherent motion that holds together across the frame.
Pricing is flat per video and tiered by resolution and duration rather than billed by the second, so the cost is predictable before you hit generate. Pick your settings, write your shot, and HexGen handles the rest.
