Pricing

Prices are in USD. The API uses a separate USD balance. Website credits cannot be used or transferred to it, and API funds cannot be transferred to website credits. When a task is accepted, we reserve the maximum quoted amount from your API balance. On completion, we charge for actual usage, never more than the hold, and release the remainder. If the task fails, the hold is released.

OptionUSD per second
resolution 480p$0.015
resolution 720p$0.024
resolution 1080p$0.032

Send the same request body to POST /jobs/quote to see the estimated and maximum USD charge before running. A quote does not run the task or charge your balance.

Use cases

Multi-shot sequences

A wide shot, a close-up and a medium shot in one clip.

9:16 for phones.

Prompt guide & pro tips

Quote the dialogue

Put spoken lines in double quotes and say who speaks.

Give the shots times

"From 0 to 4 seconds... At 4 seconds the shot cuts to...". Repeat who is in the scene.

Choose the input mode

Start with text to video when you have no reference material. Use image to video to animate a starting image, or reference to video to guide a clip with images, video or audio references.

Keep prompt expansion off

It made no visible difference in our tests, so keep it off for literal direction.
