Dog photo to a 5-second clip with sound: six Sume models

Sending one dog photo as the first frame for a 5-second clip costs $0.38 on minimax-h3 (768p native), $0.63 on wan-3.0 or gemini-omni-flash-1.1 at 720p, $0.94 on seedance-2-mini, $1.05 on kling-3 with sound and $2.89 on seedance-2.5. Those are Sume's billable prices: the catalog rate times 1.25, rounded up to the cent.

Two of these always return sound. Omni Flash 1.1 and H3 have native audio with no toggle, and generate_audio: false is a 400 on Omni. If you want to lay your own music over the clip, pick a model that accepts the toggle, or trim the audio afterwards. Source: Video Router, read 2026-10-06.

What does each cost for the same photo?

Same input, same 5 seconds, each model at the closest 720p rung it offers.

How do I send it?

Put the photo in frame_images as the first_frame. A single photo in input_references instead is reference-to-video, which conditions the whole clip on the dog but does not pin the opening frame. That split is how /v1/videos avoids the old single-image ambiguity, described on Video generation.

What should I watch for?

Run the cheapest row first. A pet photo with a clear face and one simple motion rarely needs the $2.89 tier; move up only if the cheap take loses the dog's markings. Sume reserves the price when you submit, so check the balance before queueing a batch.
