Create Synchronized Video + Audio with LTX-2 19B Distilled (Without the Local Setup)
LTX-2 19B Distilled is a Lightricks-developed, diffusion-based audio-video foundation model designed to generate synchronized video and audio within a single model, built on a DiT-based approach and published with open weights for practical execution.
In the official LTX-2 checkpoint lineup, the variant named ltx-2-19b-distilled is described as the distilled version of the full model, with a distilled configuration note of 8 steps and CFG=1.
For creators, the real win is how controllable LTX-2 becomes when you treat prompts like a mini “shot list” (scene + subject + camera + motion + audio cues) and pair that with sensible generation settings. The official workflow guidance includes standard resolution presets like 768×512, 512×768, 704×512, 512×704, and 640×640, along with a maximum of 257 frames (~10 seconds at 25 fps) and selectable frame rates such as 24 fps, 25 fps, and 30 fps.
Two “Turbo” Workhorses on One Platform: LTX-2 19B Distilled vs Kling 2.5 Turbo Pro
Both models target fast, cinematic short-form generation—but they expose different controls and (officially documented) limits. Here’s a spec-first comparison using only officially published documentation for each exact variant name.

Detailed Analysis
Analysis: Synchronized Audio + Video vs Video-Only Disclosure
LTX-2 is explicitly positioned as an audio-video foundation model that can generate synchronized audio and video within a single model. That matters for creators who want sound design, ambience, or dialogue cues to be part of the same creative pass—especially when iterating on timing, emotion, and camera direction together.
For Kling 2.5 Turbo Pro, the official fal API documentation focuses on returning a generated video file and does not explicitly document audio generation behavior for the exact “Turbo Pro” variant in the schema section—so in a strict spec comparison, audio support should be treated as not officially documented here.
Analysis: Predictable Control Knobs for Short Cinematic Shots
LTX-2’s open-source workflow guidance publishes concrete, repeatable settings (preset resolutions, a documented maximum frame count, and standard FPS options). That’s valuable when you’re building a consistent creative pipeline—because your team can standardize outputs, iterate faster, and reduce “mystery settings” between projects.
On the Kling 2.5 Turbo Pro side (via fal), you get clean, API-level controls for duration (5 or 10 seconds), aspect ratio (16:9 / 9:16 / 1:1), and a documented cfg_scale default—great for production integration, but with fewer officially exposed display specs like resolution or FPS in the schema itself.
Verdict: LTX-2 19B Distilled Is the Best “Spec-Transparent” Starting Point
How It Works
Follow these 3 simple steps to get started with our platform.
Step 1: Write a shot-list style prompt
Describe the scene, the subject’s actions, the camera movement, and the intended sound cues (ambience, dialogue, music, or Foley).
Step 2: Choose generation settings on Vidofy
Pick the format that matches your target platform (landscape, portrait, or square) and select the workflow mode you need (text-to-video or image-to-video).
Step 3: Generate, review, and iterate fast
Run multiple variations, refine only what changed (camera, motion, lighting, sound), and keep your best results organized for final export.
