Run LTX 2.5 Pro

Overview

LTX 2.5 Pro, from LTX Studio, generates 1080p video with native audio and multi-shot scenes. It works from a text prompt on its own, or from an image: supply a first frame and it switches to image-to-video, optionally interpolating toward a closing frame.

It is aimed at cinematic output. You choose the frame rate, the clip length, the orientation and even a forced camera move, and the model produces the picture and a synchronized audio track together.

What it does well

  • Native audio. Add sound cues to the prompt and an audio track is generated with the video. You can switch it off for a silent clip.
  • Camera control. A camera motion setting can force a dolly in or out, a move left or right, a jib up or down, a static shot or a focus shift. Leave it on auto and the prompt drives the move.
  • Frame rate options. 24 or 25 frames per second for a cinematic look, or 50 for smoother action.
  • Image-to-video. A first frame anchors the start, and a last frame can close it.

Prompting tips

Write the scene, the action, the camera and the sound as one flowing paragraph. Use a six second clip for a single action and the longer options for a sequence of beats. Use 720p for drafts and 1080p for the final render. A first frame works best as a high-resolution JPEG or PNG.

Limits to know

Clip length is a choice of 6, 8 or 10 seconds. The closing frame cannot be combined with automatic duration. Orientation is 16:9 or 9:16. This model is billed on the real cost of each run, so the price depends on length and resolution and is quoted on the Run button before you spend.
