From $0.157 / second

per second of generated video — price depends on requested size/resolution

Text-to-video

Resolution (via `size`)	Price
720p	$0.157 / second
1080p	$0.235 / second

Image-to-video

Same rate as text-to-video above — attaching a starting image never changes the price.

Reference-to-video

With reference images only: same rate as text-to-video above — no extra charge per image.

Attach a reference video (not just images) and the same per-second rate above also bills for your reference video's own seconds, on top of your output's seconds.

Formula: rate × (your reference video's seconds + your output's seconds) — e.g. at $0.157/s, a 5s reference video plus a 5s output bills 10s = $1.57.

+ VideoRouter platform fee: 2.5% of provider cost (≈ $0.0039) — billed as its own line, never blended into the price above.
