Prompt, method & costs
Same input; different native recipes
Twelve requests shared the exact image and supplied prompt: two takes per setting, no automatic retries. Kandinsky’s step settings are separate arms; seeds differ. H3 used balanced prompt expansion; Kandinsky and LongCat expansion was off. LTX and Grok’s internal rewriting is unverified.
Supplied prompt
A single continuous realistic shot. Preserve the woman in the starting image: same face, dark curly bun, charcoal sweater, home dining table, laptop and Sunday-evening lighting. She makes a small deliberate edit using the trackpad, types a brief correction, then pauses to inspect the screen. Focused expression with mild fatigue. A restrained slow camera push; keep face and hands readable. No new people, scene changes, speaking, music, captions or logos. This illustrates an agency owner fixing client work on Sunday, paying with her own time.

Costs are estimates
Displayed rates divide historical per-take estimates by delivered duration. The source quotes used requested durations of 5 or 6 seconds. LongCat’s 5.4s request returned 11.667s, so its range covers both interpretations. Billing remains unconfirmed.
Account-verified tariffs imply $2.49–$2.53 for all twelve attempts. Final charges, rounding, fees, taxes and refunds are unconfirmed. Human acceptance is pending, so cost per usable clip is unknown.
Review limits
Files passed full decoding and have distinct hashes. Review sampled eight frames per clip and selected playback, not every frame. Names are visible here; the A–L reel hides them until its reveal.
One scene; native duration, size, frame rate, steps and prompt rewriting vary. Clips have no AI upscaling, interpolation, speed changes or trims. This does not establish a universal winner or reliability rate.
