What's New in LTX 2.5

LTX 2.5 pushes AI video further than any LTX video release before it — longer durations, higher resolutions, and audio built into the generation itself.

Up to 20 Seconds Per Clip

LTX 2.5 generates continuous video up to 20 seconds long — roughly double what most AI video models offer. Tell complete mini-stories, showcase products, or build cinematic sequences in a single generation.

Native Audio Generation

Audio is generated alongside the video: ambient sound, effects, and atmosphere that match the on-screen action. LTX 2.5 delivers a complete audiovisual clip without any post-production sound work.

Up to 4K Resolution

Render your LTX video at up to 4K resolution with fine detail and clean edges. From quick drafts to broadcast-quality masters, one model covers the entire quality spectrum.

Text-to-Video & Image-to-Video

LTX 2.5 supports both text-to-video and image-to-video workflows. Describe a scene from scratch, or animate a reference image — the model handles both with the same long-duration, high-resolution capability.

Why LTX 2.5 Is the Long Video King

When your content needs more than a five-second teaser, LTX 2.5 delivers the duration, resolution, and audio other models can't match.

Most AI video models top out at 5–10 seconds. LTX 2.5's 20-second generations let you build real narrative beats — establishing shots, action, and resolution — without stitching multiple clips together.

LTX 2.5 Technical Capabilities

Six core features that make LTX 2.5 the leading long-form AI video generator.

Extended 20-Second Generation

Generate coherent video sequences up to 20 seconds long — enough for complete scenes, product demos, and story arcs that shorter models simply can't fit.

4K Resolution Output

Render at up to 4K for crisp, detailed footage suitable for large screens, broadcast, and professional post-production pipelines.

Synchronized Native Audio

LTX 2.5 generates audio together with the visuals — ambience, effects, and soundscapes aligned to the action in every frame.

Dual Input Modes

Full support for both text-to-video and image-to-video, so you can start from a written concept or animate existing visuals with equal quality.

Fast Generation Tier

Fast Generation Tier is available through the supported controls shown in the generator.

Consistent Long-Form Coherence

Lightricks' architecture maintains scene consistency, lighting, and subject identity across the full duration — no drift or degradation in longer clips.
