Step by step
How to use LTX-2.5 in 6 steps
- 1
Open LTX-2.5 in the Studio
Open the Studio (it opens with LTX-2.5 selected), or choose the Video tab and pick LTX-2.5 in the model menu. Sign in with Google or your email; you pay per generation from prepaid credits.
- 2
Choose what to make
- Text → Video — a prompt.
- Image → Video — a first frame and a prompt. Add it under “First frame”.
- 3
Write the prompt
One shot per prompt works best. Cover these, in plain sentences:
- Subject. Who or what is on screen, with the details that must stay consistent: age, clothing, materials, colours.
- Action. One clear action in the present tense. Keep it to one beat for short clips.
- Camera. Shot size and movement: close-up, wide, dolly-in, orbit, handheld, drone.
- Scene and light. Location, time of day, and where the light comes from.
- Style. Lens, film look, colour grade or animation style.
- Sound. LTX-2.5 generates synchronized audio with the clip, so name the ambience, effects or lines of dialogue you want.

Set the options
The settings sit under the prompt; rarely needed ones are behind ⋯. What each does — and to the price — is in the table below.

Generate
The exact price is shown before you run: press Generate (or ⌘/Ctrl + Enter). The amount is held from your balance and refunded in full if the generation fails.

Download and iterate
Results appear above the prompt; download them from there. Change one thing per try — the prompt, the camera move or a setting — so you know what helped. Compare runs the same prompt on several models side by side, and Code shows the same request for the API.

Common LTX-2.5 mistakes
Drafting at 1080p
Every try at 1080p costs 2.0× one at 720p. Settle the composition and motion at 720p, then render the keeper at the resolution you deliver.
Expecting one long take
One generation is up to 8 seconds (1–8 s). Plan longer pieces as several shots, and keep the subject consistent with the same first frame in each.
Several actions in one prompt
Give each clip one clear action and one camera move. A list of events in one prompt usually gets merged or skipped.
Describing what you don't want
Prompts work better when they describe what should be on screen. "No blur" or "no extra fingers" can pull the result towards the very thing you name.
