Working with LTX 2.3
LTX 2.3 is the generation built around longer 4K output: up to twenty seconds with synchronized audio, vertical framing for social, and a choice between 24 and 48 FPS. Its lipsync variant takes an image and an audio file and produces a talking clip with realistic facial expression.
When to choose LTX 2.3
Choose LTX 2.3 when you need a twenty-second 4K clip or explicit frame-rate control. LTX 2.5 is newer, adds audio-led generation and camera controls, but this family keeps the longest single-shot duration.
Choosing between the variants
Text to Video and Image to Video are the 4K generation routes with FPS and framing control. Lipsync is the odd one out — it takes a face image and an audio track and returns a talking video.
