LTX 2.5 First / Last Frame Guide

Plan LTX 2.5 first/last-frame transitions with stable identity, coherent motion and an explicit path from the opening frame to the target frame.

How this workflow works

When both start and end images are supplied, the prompt should explain the motion that connects them. Do not re-describe the two frames as separate scenes; describe the transition path.

Step 1

Lock what must stay constant

Call out identity, product geometry, wardrobe, lighting direction or environment elements that must survive the transition.

Step 2

Describe the path, not just the destination

State how the subject and camera move from the first composition to the last. Use one coherent motion arc.

Step 3

Match the frames before generation

Large changes in identity, lens, lighting or scene geometry force the model to invent too much. Similar visual structure usually produces cleaner interpolation.

Prompt example

A practical starting structure

Preserve the same woman, red coat, street and evening lighting. From the opening medium shot, she turns toward the storefront while the camera slowly arcs right. Her position and body orientation change continuously until she reaches the final three-quarter pose shown in the end frame. No cuts or identity drift.

What this page is meant to answer

Use LTX 2.5 First / Last Frame Guide for explanation, setup choices and workflow checks rather than immediate prompt generation. It is the informational layer for this specific search intent.
