Art-directed frame
Gen 4 Turbo motion
Gen 4 Turbo is the faster, lower-cost tier of Runway’s Gen-4 video model. Runway built it for quick iteration: it animates an image you supply, which becomes the first frame of the clip, and your prompt describes the motion.
In Pixara, Gen 4 Turbo is the one Runway model available, listed in the Create Video picker next to Seedance, Kling, Veo, Wan, Hailuo and others. So this Runway video generator page is about Runway image-to-video. Runway’s own documentation now describes Gen-4 as an older generation, with Gen-4.5 its newest model in Runway’s own app.
Upload an image. A JPG, PNG or WebP up to 10 MB. Gen 4 Turbo needs one.
Describe the motion. What moves, how the camera moves and the pace.
Select Runway Gen 4 Turbo in the model picker.
Choose duration and ratio. 5 or 10 seconds, and one of six aspect ratios.
Generate and compare. Review the clip, then try the same image on another model if it helps.
For image preparation, motion prompting and troubleshooting in depth, see how to animate an image with Pixara.

Start with Runway Gen 4 Turbo when you want a fast, style-conscious image-to-video test. Compare another Pixara model when your project depends on audio, longer duration, reference inputs or different controls.

10 seconds
Based on each model’s documented controls, not a Pixara benchmark.
Test subtle motion, camera moves and visual direction without rebuilding the scene.
Use 9:16 for vertical posts, 21:9 for cinematic compositions and other ratios for campaign variations.
Use a 5-second clip as a visual proof of concept. It won’t predict exactly how another model will behave.
Create variants for social, web and presentations from one approved image you have rights to use.
Runway’s Gen-4 Video Prompting Guide gives this advice for its Gen-4 models:
Formula
Subject motion + Camera motion + Scene motion + Style or pace
Example
“The camera pushes in slowly as the subject turns towards the light. Leaves drift through the background. Calm, cinematic pace.”
Negative to positive
Instead of “No camera shake, don’t change the product.”
try “Locked camera, the product stays still and upright, soft studio light moves across it.”
One source image and one prompt, run on Gen 4 Turbo and another Pixara model. Neither is presented as the winner: the point is to see how two models read the same motion.
Source image, then Gen 4 Turbo and Seedance 2 with the same prompt, 16:9, 5 seconds; date and a neutral observation to be recorded. The second model is a suggestion; any image-capable Pixara model works.
