Frequently Asked Questions

How long can a Runway Gen-4 video be? +
Standard Gen-4 use caps around 16 seconds per generation, and Runway has demonstrated continuous generations up to 60 seconds with temporal consistency in specific configurations. For short-form reels the standard length covers most single shots, with the editing suite handling cuts between them.
How much does Runway cost? +
Plans run from roughly $12 to $15 a month for Standard up to $188 for Unlimited as of June 2026. The catch is credit burn, a 10 second 1080p Gen-4 clip costs roughly 100 to 150 credits, so the Standard plan covers only a handful of finished clips per month.
What makes Runway different from Sora 2 or Kling? +
The suite. Runway pairs its models with editing, upscaling, and even access to third-party engines in one subscription, so generation and post-production live in the same tool. Pure model quality benchmarks shift every quarter, but the workflow integration is the reason teams stay.
Do I need Runway to make AI influencer videos? +
No. Runway is an editor's tool, and an AI influencer channel is an operator's job. AvatarFactory builds the consistent character, writes performance-tested hooks, renders a publish-ready reel in about 3 minutes, and auto-publishes to Instagram, TikTok, and YouTube Shorts on a daily schedule.
