TL;DR
- 4 ready-to-use image-to-video scenes: a landscape first frame with motion, a day-to-night first/last-frame transition, a silent vertical craft close-up, and a product orbit — all real
ltx-2.5-fast/image-to-videoclips; 720p runs $0.215 for 5 seconds. - Each scene lists the input frames, the prompt, and a pre-fill link. Code lives in the API guide.
- New accounts get 200 credits; generating from scratch is covered in the text-to-video prompt guide.
Scene 1: Animate a landscape (single frame + push-in)


Waves crash against the rocks below the lighthouse, seagulls glide across the golden sky, the camera slowly pushes in, sound of surf and gulls
(Upload the lighthouse photo as the first frame; 720p, 6 s, 16:9.)
ltx-2.5-fast/image-to-video, 720p, 6 s, 16:9, 1280×720, audio, $0.258.
How to write it: the prompt adds only what the still lacks — surf, gulls, a push-in, and the sound. What's in the frame stays in the frame.
Scene 2: First + last frame: day to night



Time passes from bright winter day to starry night, the sky darkens, the cabin windows light up warmly and smoke rises from the chimney, an aurora appears, fixed camera
(Upload the day and night images; 720p, 5 s, 16:9.)
ltx-2.5-fast/image-to-video, first + last frame, 720p, 5 s, 16:9, $0.215.
How to write it: the two frames set the endpoints; the prompt describes the process and the rig (fixed camera). Keep both frames at the same aspect.
Scene 3: Vertical craft close-up (audio off, score in post)


The potter's hands shape the spinning clay vase, it rises smoothly, wet clay glistens, slow subtle camera drift
(Upload a vertical workbench photo; 720p, 5 s, 9:16, generate_audio: false.)
ltx-2.5-fast/image-to-video, 720p, 5 s, 9:16, 720×1280, silent (generate_audio: false), $0.215.
How to write it: pair a vertical first frame with 9:16 output; mute for clean footage you'll score yourself — the price doesn't move.
Scene 4: Product orbit


Rose petals drift down around the perfume bottle, a slow orbit of the camera, light glints across the amber glass, soft piano
(Upload the product shot as the first frame; 720p, 5 s, 16:9.)
ltx-2.5-fast/image-to-video, 720p, 5 s, 16:9, 1280×720, audio, $0.215.
How to write it: with the product as the first frame, give the camera path, one falling element, and a music cue — orbit, petals, soft piano — and the showcase clip assembles itself.
How to write these prompts (3 lines)
- Write only what the still lacks: motion, camera, sound; the frame carries the rest.
- For first+last frames, describe the process and the rig: how the light changes, when windows glow, whether the camera moves.
- Match
aspect_ratioto the first frame to avoid crops and bars.
FAQ
- Yes, two images max: one first frame, or first plus last; a third returns a 400.
- Yes, muting doesn't save money:
generate_audio: falsegives clean footage at the same price. - Yes, $10 buys about 38 clips (720p, 6 s each; a 5-second clip is $0.215).
Next: pick one of your product shots or landscapes, follow the link to pre-fill the prompt, upload the first frame, and run a 5-second take.
