LTX Video 2.0 Fast | [text-to-video]
Lightricks' LTXV 2.0 Fast delivers 6-20 second video generation with synchronized audio at $0.04 per second (1080p). Trading maximum resolution flexibility for speed optimization, this model runs 30x faster than traditional diffusion approaches through multiscale rendering architecture. Built for rapid prototyping workflows where iteration speed and cost efficiency outweigh 4K output requirements.
Use Cases: Social media content creation | Advertising concept testing | Rapid video prototyping
Performance
At $0.04-$0.16 per second depending on resolution, LTXV 2.0 Fast positions as a cost-optimized endpoint within the LTX Video 2.0 family, trading render time for accessibility in high-volume production environments.
| Metric | Result | Context |
|---|---|---|
| Generation Speed | 30x faster than traditional diffusion | Multiscale rendering vs standard latent diffusion |
| Duration Range | 6-20 seconds | Durations over 10s require 25 FPS and 1080p |
| Cost per Second | $0.04 (1080p), $0.08 (1440p), $0.16 (2160p) | 25 generations per $1.00 at 1080p/6s baseline |
| Audio Generation | Native synchronized audio | Integrated audio synthesis, no post-processing |
| Related Endpoints | LTX Video 2.0 Pro | Pro variant for extended duration and higher fidelity |
Speed-Optimized Video Synthesis with Audio
LTXV 2.0 Fast uses multiscale rendering to generate video frames at multiple resolutions simultaneously, then combines them during final output. This contrasts with traditional latent diffusion models that process each frame sequentially at full resolution.
What this means for you:
-
Synchronized Audio Generation: Native audio synthesis eliminates separate sound design workflows. Prompt "cinematic depth, western mood" and receive matched audio automatically
-
Flexible Duration Control: Generate 6-20 second clips with frame-level precision at 25 or 50 FPS, though longer durations (12-20s) lock to 25 FPS at 1080p
-
Resolution Scaling: Choose 1080p, 1440p, or 2160p output with proportional cost scaling. 1440p doubles cost to $0.08/second, 4K quadruples to $0.16/second
-
16:9 Native Output: Fixed aspect ratio optimized for standard video platforms, reducing post-production cropping for YouTube, Instagram Reels, and TikTok formats

How It Stacks Up
LTX Video 2.0 Pro ($0.10/second at 1080p) – LTX Video 2.0 Fast trades extended duration capabilities and higher base fidelity for 2.5x cost efficiency at standard resolutions ($0.04 vs $0.10). Pro supports longer clips beyond 20 seconds and maintains quality at extended durations, ideal for narrative content where runtime flexibility justifies increased cost.
Hunyuan Video V1.5 (see pricing) – LTXV 2.0 Fast prioritizes integrated audio generation and rapid iteration speed through multiscale rendering. Hunyuan emphasizes maximum visual fidelity and complex scene composition for workflows where render time is secondary to output quality.
LongCat Video (see pricing) – LTXV 2.0 Fast offers native 1080p and higher output with synchronized audio at competitive pricing. LongCat targets 720p workflows optimized for mobile-first content where file size and bandwidth efficiency outweigh resolution requirements.
