Runway Gen-4 AI Video Generator
Runway Gen-4 holds characters, places, and objects across new angles from a single still. It animates that required first frame for 5 or 10 seconds at 24 fps, with Gen-4 Turbo as the faster, lower-cost sibling.
What is Runway Gen-4
Runway Gen-4 is Runway's image-to-video model for world consistency. Gen-4 Turbo is the faster, lower-cost sibling. CamArt's generate default on this page is the Turbo endpoint, not Gen-4.5 and not a text-only generate path.
World consistency
Characters, locations, and objects are meant to hold across new angles and treatments from the same look.
Still as first frame
An input image is required. It sets subject, light, and style before you describe motion.
Motion-first prompts
Text should name action and camera, not restate the picture.
5 or 10 seconds
Official clips are 5s or 10s. CamArt Turbo also offers the seconds in between.
720p-class, 24 fps
Help lists 1280x720 and matching portrait and square sizes at 24 fps.
Turbo for iteration
Gen-4 Turbo is the fast, cheaper SKU. CamArt's generate default is this endpoint.

Key Features of Runway Gen-4 AI Video Generator
What Runway documents for Gen-4, written as controls you can actually use: a required still, motion-first prompts, world consistency, and Turbo length at 24 fps.
-
World consistency from one still
Gen-4 is built so a character, place, or object can hold across new angles and lighting from a single look, without a fine-tune.
-
Required first-frame image
Official Gen-4 and Gen-4 Turbo both need an input still. That picture sets subject, light, and style before you describe motion.
-
Motion and camera in the prompt
Help treats the prompt as action and camera language. Do not restate wardrobe and lighting already in the photo.
-
Physics-aware motion
Issuer reels show cloth, hair, and object weight as the motion test. This is not a Hollywood VFX guarantee.
-
5 to 10 seconds at 24 fps
Official clips are 5s or 10s at 24 fps in 720p-class ratios. CamArt Turbo also offers the seconds in between. No 21:9 on CamArt.
-
Turbo for iteration
Gen-4 Turbo is the faster, lower-cost sibling. CamArt's generate default is this endpoint, billed at 1 credit per second.
Describe motion, not the look already in the still.
Gen-4 follows action and camera language when the first frame already carries subject, light, and style. Keep the prompt short enough to finish inside 5 or 10 seconds.

Why Choose Runway Gen-4 AI Video Generator in CamArt
Choose Gen-4 when the job is a consistent character or product from one photo, animated for 5 to 10 seconds. CamArt runs Gen-4 Turbo on this page.
Keep a character or product on-model
Gen-4 is meant to hold a face, a place, or a pack shot across new coverage from one still. You do not fine-tune a LoRA to get that hold.
- Upload one clear still of the person, set, or product.
- Change angle and lighting in the motion prompt, not by restating the wardrobe.
Animate the still you already have
The input image is the first frame. Product tables, portraits, and location stills keep their look while you write motion and camera.
- Add the still in the tool before you Generate. It is required.
- Keep the prompt short enough to finish inside 5 or 10 seconds.
See hair, cloth, and weight move
Issuer physics reels treat cloth, hair, and object weight as the motion test. Write the action you want in those 5 to 10 seconds.
- Name the camera move instead of hoping the model invents one.
- Iterate on Turbo when you are still finding the take.
See CamArt credits before you Generate
Gen-4 Turbo on CamArt is 1 credit per second. A 5 second clip is 5 credits and a 10 second clip is 10 credits. The button shows the charge before you start.
- Draft at 5 seconds, finish at 10 when the motion needs the extra beat.
- Video Editor Aleph is a separate 90 credit edit, not this generate default.

Hit Generate. Preview the silent clip, then save from Creations. Use Video Editor Aleph only when you need to edit an existing clip.
Who Should Use Runway Gen-4 on CamArt
Gen-4 fits briefs that start from a still and need a short, consistent motion pass. Longer audio-video stories belong on other CamArt models.

-
Brand and campaign marketers
Keep a face or location on-model across short 5 to 10 second cuts for boards and social.

Product and ecommerce teams
Start from a pack shot. The still carries the look. The prompt only has to move the camera or the object.
-
Social and UGC editors
9:16 and 1:1 are on CamArt Turbo. Clips are silent, so add sound in another tool if the brief needs a track.
-
Concept artists and look-dev
Test world consistency from one key still before a longer shoot or a later model.
-
Agencies iterating on Turbo
See credits on Generate, then finish or edit elsewhere. CamArt Aleph is the in-context editor, not this page's default.
