Formula — Gemini API direct: seconds × 5,792 output tokens × $17.50 / 1M (≈ $0.1014/s, Google rounds to ~$0.10/s) + input tokens × $1.50 / 1M; paid tier only, and Google publishes the token rate for 720p only. Runway Dev: seconds × resolution rate ($0.034 / $0.10 / $0.15 / $0.30 per s) + $0.01 per reference image or keyframe + $0.01 per second of input video, rounded up to a whole credit ($0.01), audio included. Per kept clip = per generation × takes; monthly = kept clips × per kept clip. Input-token defaults for images and video are assumptions — edit them.

How it works
- How much does Gemini Omni Flash cost per second?
- On the Gemini API (paid tier only), gemini-omni-1.1-flash bills output video at $17.50 per 1M tokens and 720p uses 5,792 tokens per second, so about $0.1014 per second (Google rounds to ~$0.10). Input is $1.50 per 1M tokens. On Runway Dev, Omni Flash 1.1 is $0.034/s at 360p, $0.10 at 720p, $0.15 at 1080p and $0.30 at 4K, audio included.
- What does an 8-second 720p clip cost?
- Gemini API direct: 8 × 5,792 = 46,336 output tokens × $17.50 / 1M ≈ $0.81 plus input tokens. Runway Dev: 8 × $0.10 = $0.80. With 3 takes per kept clip, multiply by 3.
- What extras does Runway charge for Omni Flash?
- Each reference image or keyframe adds $0.01 (on image-to-video the first and last frame each count), input video adds $0.01 per second, and each generation rounds up to a whole credit. A duration of auto is pre-billed as 10 seconds and the unused part is refunded when the task finishes.
- How are extend and edit billed, and are failed tasks charged?
- On Runway Dev, extend and edit render at 720p and bill at the 720p rate — an edit on the length of its source clip, an extension on the footage it adds. A task that fails input moderation (SAFETY.INPUT.*) is still charged; errors on Runway's side are refunded automatically.
- Can I use Gemini Omni Flash on the free tier?
- No. Google lists Omni Flash as not available on the free tier; you need a paid Gemini API project. Google publishes the token rate for 720p only, so this calculator shows Gemini-direct cost at 720p and Runway Dev at every resolution.
