## Intent

LTX 2.3 Pro is a 6/8/10s 4K production SKU with fps control. Wan 2.7 is a 2–15s 1080p generalist with references and native audio.

## Verdict

LTX 2.3 Pro uses fixed 6, 8, or 10 second durations at 1080p, 1440p, or 4K, 16:9 or 9:16, with optional audio, first/last frames, and 24–50 fps options—no reference packs. Wan 2.7 lists 2–15 seconds at 720p or 1080p with native audio, first/last frames, up to nine references, and negative-prompt/seed controls. Choose LTX when resolution and frame rate are the production constraint; choose Wan 2.7 for repeatable social footage with references.
