Runway’s current help page says the Free plan includes a one-time deposit of 125 credits that does not expire. That is a finite starter allowance, not a recurring monthly balance. The same page lists Gen-4.5 at 12 credits per second of generated video, so a five-second generation at that rate costs 60 credits and a ten-second generation costs 120. Those figures let you plan a test, but they do not promise a particular creative result or account access in every case.
Estimate the cost before generating
Choose one short shot that can demonstrate whether Runway’s output suits your idea. If you select Gen-4.5 at the listed rate, multiply the output duration by 12 credits per second. A five-second clip is 60 credits; two such generations would total 120 credits, leaving five from the initial 125 before any other credit-consuming activity. If you lengthen a clip or pick another model or tool, the cost may differ.
Credits are not an unlimited video quota. Retries can use the same balance, and a generation that misses the prompt still consumes time and may consume credits. Runway says the Free plan’s deposit does not expire, but Free users cannot buy extra credits through the described plan flow. Check the credit table and balance inside your account before starting a batch.
A low-waste first-generation workflow
- Decide the clip’s job: a close-up, a transition, a product atmosphere shot, or one moment in a short story.
- Draft the prompt outside the generation box. Specify subject, action, setting, camera movement, lighting, framing, and what should remain out of frame.
- Choose the shortest useful duration and suitable model. Confirm the displayed cost before submitting.
- Generate one version and evaluate motion, subject consistency, camera behavior, and visual artifacts.
- Change one prompt detail for a second attempt rather than generating several vague variations.
- Download the result you intend to keep and assemble it with your own edit, narration, and licensed audio.
For example, instead of “make a cool ad,” try “five-second vertical close-up of a reusable glass water bottle on a sunlit hiking table; slow camera orbit, clean natural color, no logos or readable text.” This gives a model observable direction and reduces dependence on text rendered inside the image.
Check rights and free-plan conditions
Runway’s credit page explains product credit use, not the rights status of every prompt, input, or final use. Check the current terms and account-specific plan before using a result commercially. Do not upload a person’s image, brand mark, or protected footage unless you have the necessary permission. Avoid using a generated likeness to imply someone endorsed a product.
If you need a more generous no-cost editing route than a small one-time generation balance, compare Google Vids’ current free workflow with Canva’s short text-to-video feature. Each has different controls and allowances; “free” usually describes access to a feature, not unlimited production.
