LightricksLTX-2.3 Pro
LTX's mature full-workflow video model for generation plus Retake, Extend, Reframe, native audio, and first-to-last-frame control.
Plain-English overview
What LTX-2.3 Pro actually is
LTX-2.3 Pro remains useful beside the newer 2.5 family because it supports more editing endpoints. Teams can generate from text, images, or audio and then repair a section, extend a clip, or reframe existing footage using the same API family.
It supports output up to 4K and several cinematic frame rates, with price varying by resolution and operation. That makes it a strong workflow model when controllable iteration matters more than selecting the newest checkpoint name.
Good fit for
- Video pipelines that need generation and editing
- First-to-last-frame interpolation
- Retake, Extend, and Reframe workflows
