Tencent's Hunyuan Video 1.5 delivers up to 121 frames of 480p video at $0.075 per second of output. Trading resolution for prompt adherence and motion quality, the model generates approximately 5 seconds of video in 3 minutes. Best suited for rapid prototyping, social media content, and iterative creative workflows where speed and cost efficiency matter more than 4K output.
Use Cases: Social Media Content | Concept Visualization | Rapid Prototyping
At $0.075 per second of video output, Hunyuan Video 1.5 positions as a cost-effective text-to-video option for standard-definition workflows, with pricing roughly 13 generations per $1.00 on fal.
| Metric | Result | Context |
|---|---|---|
| Resolution | 480p (16:9 or 9:16) | Standard definition optimized for web/social |
| Inference Speed | ~3 minutes | For 121-frame generation |
| Cost per Second | $0.075 | 13.3 seconds per $1.00 on fal |
| Max Duration | 121 frames (~5 seconds) | At default frame count |
| Related Endpoints | Hunyuan Video | Standard variant of same model family |
Hunyuan Video 1.5 uses Tencent's diffusion architecture optimized for semantic understanding rather than pixel density. Unlike models that prioritize 4K output at the expense of prompt adherence, this approach focuses computational resources on motion coherence and text interpretation.
What this means for you:
Prompt Expansion Built-In: Optional automatic prompt enhancement improves scene detail and motion quality without manual prompt engineering
Flexible Aspect Ratios: Native 16:9 and 9:16 support eliminates cropping for vertical social content or horizontal web video
Reproducible Generations: Seed control enables exact recreation of successful outputs for iterative refinement workflows
Controlled Inference Steps: Adjustable from 1-50 steps (default 28) lets you trade generation time for quality based on project requirements
