LTX 2.3 Fast
Strengths: Audio & Lip Sync, Prompt Adherence
Compare engines
Compare current LTX 2.3 Fast with available Wan 2.5 Text & Image to Video. LTX reaches 4K, supports longer constrained clips, and lists a lower shared 1080p rate; Wan keeps 1:1 output and lower-resolution 480p/720p entry options for simple ten-second jobs.
Quick verdict
Stay on available Wan 2.5 Text & Image to Video for existing simple work or 1:1 and lower-resolution output; upgrade to current LTX 2.3 Fast for 4K, lower listed 1080p pricing, or longer constrained clips. Above 10 seconds, LTX requires 1080p at 25 fps.

Stay with Wan for accessible formats
Keep Wan 2.5 for simple text/image generation with audio in 480p, 720p, or 1080p and 16:9, 9:16, or square output.
Move to LTX for higher resolution
LTX 2.3 Fast adds 1440p and 4K, broader FPS selection, and a lower listed rate than Wan at their shared 1080p resolution.
Key format and duration trade-off
Wan provides 1:1 and lower-resolution entry tiers; LTX adds high resolution and longer output, restricted above ten seconds to 1080p at 25 fps.
Best workflows for each model
Use Wan for simple square or entry-resolution clips; use LTX for 1080p value, 1440p or 4K delivery, and constrained longer landscape or portrait shots.

What it tests: Motion Realism + Temporal Consistency + Visual Quality
Wide 16:9 cinematic action shot, a runner sprints through a rainy city street at night, water splashes realistically with each step, reflections on wet asphalt, handheld tracking camera following from the side. Dynamic motion with believable inertia and physics, no rubbery limbs, no wobbling background, stable scene geometry, minimal temporal flicker, sharp details despite fast movement, realistic motion blur.

Wan 2.5 Text & Image to Video
What it tests: Human Fidelity + Audio/Lip Sync + Prompt Adherence
Vertical 9:16 TikTok-style UGC selfie video, handheld smartphone feel, natural indoor daylight near a window. A friendly creator speaks directly to camera with natural blinking, subtle head nods, and a warm smile. Add small human imperfections: a tiny hesitation, a soft breath, a quick smile mid-sentence, and a micro-pause before the last line. Realistic skin texture, stable identity, no face warping, minimal flicker, clean audio with natural room tone. No subtitles. No on-screen text. No logos. No watermarks. The creator says (exactly, with the same pacing and hesitations): “Okay, so… um… quick thing. If you’re feeling stuck, just do the tiniest first step… like, set a two-minute timer and start. (smiles) That’s it. You’ll be surprised how fast it gets easier.”

Wan 2.5 Text & Image to Video
What it tests: Hands/Fingers + Text & UI Legibility + Prompt Adherence
Wide 16:9 full-body unboxing video in a clean studio/kitchen setting. A person is fully visible (head-to-toe or at least head-to-knees) standing behind a minimalist tabletop. They unbox a small generic gadget from a plain matte cardboard box: peel the seal, open the lid, remove the inner tray, take out the device and accessories, and lay everything neatly on the table. The person occasionally lifts the item toward the camera for a closer look, then places it back down. Realism requirements: natural body proportions, stable identity, realistic skin and clothing fabric, no face warping, no unnatural limb bending. Hands must be highly realistic: correct finger count, natural grip, believable pressure/contact with the box and device, consistent shadows, no extra fingers, no “floating” objects. Keep object geometry stable, no wobbling background, minimal temporal flicker. Camera: single continuous shot, tripod-stable, slight cinematic push-in (very slow), eye-level or slightly above table height. Natural soft daylight, clean shadows, realistic materials and textures. No logos, no brand names, no watermarks. No subtitles. Optional on-screen title at the top (perfectly readable and stable, no jitter): "UNBOXING — FIRST LOOK"

Answers for Wan 2.5 continuity and migrating higher-resolution jobs to LTX 2.3 Fast.
Stay on the available model for simple ten-second text/image clips, especially when 480p, 720p, or native 1:1 output fits the channel.
LTX lists a lower per-second price at the shared 1080p tier and adds 1440p, 4K, and more frame-rate choices for current production.
No. Its generations above ten seconds require 1080p at 25 fps, so 1440p and 4K work must stay at ten seconds or less.
