B-Roll Footage Generator Prompt for LTX
This is the LTX version of the b-roll footage generator prompt: clean, narration-ready B-roll: one subject, one gliding camera move, nothing that fights a voiceover or an edit. It is formatted the way LTX takes prompts best. Free — copy it, replace the bracketed parts, and paste it in.
The prompt
Push copies this prompt with a reference line naming your image, and downloads the image file — attach it in the model to complete the pair. This page stages the pair for you; it cannot upload into the model itself (sites cannot reach into each other), so the final attach happens there. The image is downscaled to at most 1024px and stored only in this browser, paired with this prompt. If browser storage is full, it is kept for this visit only.
The deliverable — and how to check it
Deliverable: one 8-second clip with a single continuous camera move and no cuts, subject in frame for the full duration, clean head and tail (at least 1 second of settled frame at each end for edit points). Acceptance check: the clip must sit under narration without any moment that pulls attention — no faces to camera, no text, no sudden movement.

Using this prompt with LTX
LTX (Lightricks, current LTX-2 generation) is an open audio-video model: it generates synchronized sound and picture in one pass, so the prompt must describe the soundtrack — music, ambience, dialogue — as fully as the image. It rewards verbose, shot-by-shot prose over compressed lines. The open weights run locally (the full model wants serious GPU memory; quantized and distilled checkpoints run lighter) under the LTX license, and there is a hosted LTX platform and API. Negative prompting is supported in the local pipelines.
What this route costs — and how to pay less
Cost structure: open weights — LTX runs on your own hardware under its license (free below a revenue threshold), so the marginal cost per generation is zero; Lightricks also sells a hosted platform and metered API. The same prompt is pre-configured in this library for every major model, so you can run it on whichever route fits your budget — comparing the structures before you generate is a free way to save money.
Replace the bracketed placeholders — [SUBJECT OR PROCESS], [SETTING], [LIGHT] — with your own details before pasting.
