Why creators choose LTX-2.5

LTX-2.5 solves one problem perfectly: turning a still photo into a talking head video. When you have a script and a portrait, LTX-2.5 animates it with tight lip sync and natural facial movement. No avatar, no uncanny valley, just motion that fits the audio. It's built specifically for this task, not as a side feature of a general video model.

Tight lip sync every time

LTX-2.5 syncs mouth movements to every phoneme. The lip sync isn't an approximation, it's trained in. Watch the model work and you'll see mouths match dialogue, not speech that approximates the mouth. The animation understands the mechanics of speech, so /p/ sounds open the mouth differently than /m/ sounds.

Natural facial animation

More than just mouth movement. Eyes, cheeks, and expressions move with the audio. Eyebrows raise on emphasis, the jaw opens and closes naturally, and the head tilts to match the intonation of the speech. The whole face participates in the animation, not just the mouth.

Fast turnaround for talking heads

Script the voiceover, have talent record it, upload a photo, and Craze generates the talking video. No green screen, no camera crew, no sync work. This workflow is much faster than traditional video shooting, and it works with anyone's image.

One 1080p pass

No upscaling, no separate audio sync. LTX-2.5 understands 1080p talking heads from the ground up. Lightricks built this model specifically for the talking photo use case, and it shows in the quality.

How to use LTX-2.5 in Craze

1. Upload a portrait photo: a headshot, a close-up, or a head-and-shoulders crop.
2. Upload the audio: a voiceover, dialogue recording, or speech you want the person to deliver.
3. Say you want LTX-2.5. Craze runs the model when you ask for it by name.
4. Craze generates the talking video, syncing the face animation to the audio.
5. Review in the editor. The mouth and facial movements should match the speech. If they don't, regenerate.

LTX-2.5 capabilities

LTX-2.5 specializes in audio-to-video animation. You provide a portrait photo and an audio file, and the model animates the face to match the speech. The model understands phonetics, facial mechanics, and natural animation. It generates tightly synced lip movement and realistic facial expressions that match the emotional tone of the audio.

LTX-2.5 works with still images: headshots, portraits, close-ups of faces, or character artwork. The image should be front-facing and show the face clearly. The audio can be a voiceover, dialogue, narration, or any speech recording. The model will animate the image to sync with that audio.

Lightricks released LTX-2.5 as an open-weight model in August 2026. On Craze, you just upload your image and audio, name LTX-2.5, and Craze handles the generation.

LTX-2.5 pricing

You pay per second of audio. $0.179 per second of audio. Longer audio means longer video and higher cost. The cost calculator on this page shows the exact price for your clip.

Audio-to-video animation scales with the audio duration, so a 10-second voiceover costs more than a shorter one. The pricing is straightforward and doesn't vary by image quality or other parameters.

Who LTX-2.5 is for

Voiceover and narration videos

Record a script, upload a headshot, and LTX-2.5 animates it. No on-camera talent needed. Works for product narration, brand messaging, or any voiceover-driven content.

Interviews and testimony

Convert interview audio into a video. Use a still image of the person and LTX-2.5 makes it look like they're speaking on camera. For case studies, testimonials, or interview content, you just need the audio and a photo.

Educational and tutorial content

A subject matter expert records narration. LTX-2.5 animates their image to match, and you have a professional-looking tutorial without video equipment. For online courses, training videos, and educational content, this is cost-effective.

Accessible avatars for presentations

Build a presentation where an animated avatar delivers the speech. Use a real photo or a generated character image, and LTX-2.5 animates it to your audio. For virtual presentations, webinars, and conference talks, this creates a consistent visual anchor.

Remote talent and distributed teams

When you can't get talent on set, have them record audio and use their photo. LTX-2.5 handles the rest. This is valuable for distributed teams and remote collaboration.
