LTX 2.3 Pro

LTX 2.3 Pro builds on the LTX-2 Pro foundation with new creative controls:

  • Camera Motion Control: Choose from dolly (in/out/left/right), jib (up/down), static, or focus shift to add cinematic movement.
  • Last-Frame Interpolation: Provide both a first and last frame image to generate smooth video transitions between two keyframes.
  • Up to 4K Resolution: Generate at 1080p, 2K, or 4K quality.
  • Synchronized Audio: Built-in audio generation with natural timing, dialogue lip-sync, and sound effects.

  • Extend: Append or prepend new content that seamlessly continues your original video.
  • Duration options: 6, 8, or 10 seconds.
  • Aspect ratios: 16:9 (landscape) and 9:16 (portrait).
