LTX 2.5 is a fast video model built for draft previews and frame-chained motion. Use it to preview a shot cheaply before committing credits to a premium final: it accepts a first frame and a last frame, so it is the natural engine for turning two stills into one continuous move.
| First frame | Attach a still as the opening frame — LTX animates outward from it. |
|---|---|
| Last frame | Optionally attach a target frame; LTX interpolates a continuous move between the two. |
| Motion | Describe the transition between the frames — "slow push toward the doorway", not a whole new scene. |
| Duration | LTX 2.5 Fast runs up to 20s. Keep drafts short (3–5s) to iterate cheaply. |
| Purpose | Treat LTX output as a draft — get the timing right, then re-render the keeper on a premium model. |
Copy any recipe, or run it free in the studio — the prompt prefills and the model is preselected for you.
Turn two stills into one continuous move.
Smooth continuous camera move from the first frame to the last frame. A slow dolly-in through a misty forest clearing, morning light filtering through the canopy, dust motes drifting in the beams. Steady, cinematic, no cut.
Preview a shot before spending on the final.
Cinematic 3-second draft. A vintage sports car pulls into frame on a coastal cliff road at golden hour, camera tracking laterally to match its speed, sun flaring across the lens. Rough draft to lock the timing and framing.
Bring a single storyboard frame to life.
Animate the attached still with subtle life: gentle rain begins to fall, neon signs flicker, a wisp of steam rises from the street vent, faint reflections shimmer on the wet asphalt. Camera almost still, a barely-there drift forward.
The clip invents a whole new scene.
Describe only the transition or motion between your frames, not a fresh setting.
Draft quality looks rough.
That is expected — LTX drafts are for timing and framing. Re-render the keeper on a premium model.
The frame-chain jumps.
Make sure the last frame you attach is visually close to where the first frame’s motion would land.
Motion is too aggressive.
Ask for "subtle", "gentle", or "barely-there" motion and a near-static camera.
The real leverage is in the pipeline between generations — keeping one character across every shot, and frame-chaining each clip’s last frame into the next so a storyboard becomes one continuous move. That is a built-in FXI Studio capability.
LTX 2.5 is a fast AI video model built for draft previews and frame-chained motion. In FXI Studio it accepts a first frame and an optional last frame, making it the natural engine for previewing shots cheaply and turning two stills into one continuous move.
Drafting on LTX 2.5 is fast and cheap, so you can lock a shot’s timing and framing before spending credits on a premium final. This draft-then-final workflow protects your free credits and gives you more successful shots per grant.
Attach a first frame and a last frame, and LTX 2.5 interpolates a continuous camera move between them. Extract the generated clip’s last frame and feed it as the first frame of the next generation to build a seamless sequence.
Preview a shot on a fast, cheap model like LTX 2.5 to get the motion and timing right, then re-render only the keepers on a premium model for the final. It maximizes how many good shots you get from your credits.
You can try LTX 2.5 in FXI Studio. New accounts start with 65 free credits, and each recipe has a one-click button that prefills the prompt and preselects the model.
