It always bills as one 5-second block, even if video.duration is present on the request. it costs $0.15 at 540p, $0.30 at 720p and $1.20 at 1080p.\nReframe is standard dynamic range only and bills per second. $0.03/s at 320p, $0.06/s at 540p, $0.12/s at 720p, and $0.36/s at 1080p.\n\nVideo Edit:\nVideo edits use their own rate table. HDR, and HDR + EXR edits increase costs. Each have separate 5-second and 10-second totals. HDR: from $1.08 (360p) to $4.32 (1080p) for 5s.

Each item can be either a plain image input (UUID, URL, Data URI, or Base64) or an object that pairs an image with a target position in the video.\n\nThe `frameImages` parameter allows you to constrain specific frames within the video sequence, ensuring that particular visual content appears at designated points. Position can be specified using `frame` (named positions or frame indices) or `timestamp` (seconds), depending on model support. This is different from `referenceImages`, which provide overall visual guidance without constraining specific timeline positions.\n\nWhen the `frame` parameter is omitted, automatic distribution rules apply:\n\n- **1 image**: Used as the first frame.\n- **2 images**: First and last frames.\n- **3+ images**: First and last frames, with intermediate images evenly spaced between.\n\n**Examples**:\n\n**Shorthand format:** When you don't need to specify a frame position, you can pass a plain image input directly.\n\n```json\n\"frameImages\": [\n \"aac49721-1964-481a-ae78-8a4e29b91402\"\n]\n```\n\n**Object format:** When you need to specify a position, use an object with `image` and either `frame` or `timestamp` (model-dependent).\n\n```json\n\"frameImages\": [\n {\n \"image\": \"aac49721-1964-481a-ae78-8a4e29b91402\",\n \"frame\": \"first\"\n }\n]\n```\n\n**First and last frames:** With two images, they automatically become the first and last frames of the video sequence.
