How to prompt LTX in image-to-video (start frame) mode. Every point links its source; community tips are marked. Your agent gets the same guide through the Atlas MCP (get_guide).
Prompt structure
opening frame anchor→action sequence→camera→audio
- Establish the shot (cinematography, scale); set the scene (light, palette, texture, atmosphere); action as a flowing sequence with active verbs; characters with emotion shown physically; camera movement and how subjects look after it; audio. source ↗
What the text should describe
- image_uri is the first frame; prompt = how the image should be animated (can reference details in it). Optional camera_motion enum: dolly_in/out/left/right, jib_up/down, static, focus_shift. generate_audio defaults true. source ↗
- For image-to-video from a first frame, prefer a single continuous take unless you intentionally describe a cut away from the opening image. source ↗
What not to describe
- duration null (auto-length) can't be combined with last_frame_uri. source ↗
Responds well to
- Best: cinematic single-subject scenes, clear camera language, consistent lighting, described audio; dialogue in quotes with language/accent. source ↗
Duration and limits
- API: generate_audio default true; fps default 24; retake section ≥2 s on inputs ≥73 frames; extend 2–20 s (context+duration ≤505 frames); audio-to-video length follows the audio. source ↗
Multi-shot
- Several shots joined by explicit cuts; re-establish framing, identity and audio at each cut. source ↗
- At every cut say whether music/dialogue/ambience continues or changes, and re-identify subjects. source ↗
Avoid and failure modes
- On-screen text spelling not guaranteed; chaotic physics causes artifacts. source ↗
- Don't paste a Kling/Seedance prompt into LTX unchanged: tag syntax and shot-list formatting don't carry over. Aim for ~4–8 descriptive sentences, present tense. source ↗
Negative prompt
