AI Video — Runway Act-Two — FAQ

Runway Act-Two is one of the AI video models available on Free.ai. Use the form on this page to generate a clip; below the fold you will find sample prompts, pricing, and alternatives.

On Free.ai, video generation tops out at 6 seconds per clip across all video models. To extend, use the Extend button on the full /video/ tool — it captures the last frame and continues from there.

16:9 landscape (YouTube, desktop), 9:16 portrait (TikTok, Reels, Shorts), and 1:1 square (Instagram feed). Pick the ratio in the form before you generate so the model frames the shot for that shape.

720p HD by default. Some premium models support up to 1080p — check the Compare card. You can upscale any output in /video/upscaler/ after the fact.

Strong on natural motion (people walking, cars driving, water, weather). Weaker on intricate hand interaction and fine text. Use camera-direction hints (slow pan, dolly forward) for cleaner motion.

Free.ai grants commercial use of generated videos to you regardless of model. The model itself may be Apache 2.0, MIT, or a vendor-specific license — see the model reference link below.

Runway Act-Two is a premium video model. Cost scales with duration — typically ~5,000 tokens per second. $1 buys 750,000 tokens, so a $5 token pack covers many clips. Free signups receive 10,000 tokens to try.

Yes — use /batch/ for up to 100 prompts. Each clip is queued and the result lands in /account/?tab=history when ready.

Yes — POST your prompt to /v1/video/generate/ with model="Runway Act-Two" (or use the slug on this page). See /api/ for the full endpoint reference plus auth, error codes, and SDK snippets.

We do not store your prompts beyond the share window (24h anon, 7d signed-in). We do not train on your inputs. Self-hosted models run on Free.ai-owned GPUs.

Yes — failed jobs are auto-refunded to the original payment source (daily pool or paid tokens) the same day. Email contact@free.ai if a refund did not appear.

Typical render 30–120 seconds for a 4-second clip; premium models often finish in 15–45 seconds. Use the close-tab-safe queue button on /video/ — your result lands in /account/?tab=history when done, with optional email.
