What it costs
Per second, and what a single clip comes to at each length. These are computed rather than multiplied out, so the minimum billed unit and any cap are already applied.

Others in this lane
A clip you have goes in and a changed one comes out: edited from a prompt, extended, lip-synced, dubbed, given sound, reframed, upscaled, or with its background or an object taken out. Most bill per second of the clip or audio that goes in.
