KinoviAI is an AI Video tool. API for generating videos up to 30 seconds from text, images, video, and audio with improved motion and character consistency. Best for content creation, media production and developers.
About KinoviAI
KinoviAI provides access to Seedance 2.5, ByteDance's multimodal video generation API that creates videos up to 30 seconds long from text, images, audio, or combined inputs. The platform handles the infrastructure overhead, letting you focus on prompt engineering and output refinement rather than managing generation infrastructure yourself.
The features that matter
- Multiple input modes: Text-to-video, image-to-video, multimodal reference generation, and first/last frame conditioning all available through a single API
- Frame-level editing: Fine-grained control over specific frames within generated videos, not just full-video regeneration
- Resolution & aspect ratio flexibility: Output up to 1080p in multiple aspect ratios suited to social media, presentations, or broadcast formats
- Character & motion consistency: Improved character stability across generations and smoother motion dynamics compared to earlier versions
- Asynchronous processing: REST API with webhook support so you can fire-and-forget requests instead of blocking on long generation times
- Multilingual prompt support: Better adherence to non-English prompts, expanding use beyond English-only workflows
How it stands out
Most video generation tools force you to choose between speed and quality. The tool balances both—it supports durations up to 30 seconds (longer than many competitors' minimum viable output) while maintaining smoother motion and stronger character consistency. The frame-level editing capability means you don't have to regenerate an entire video if only one or two frames need adjustment. Webhook support for asynchronous jobs is essential if you're integrating this into a production pipeline rather than using it interactively.
What to know before signing up
Generation times are not instant; you'll need to poll the API or wait for webhook callbacks, typically spanning several seconds. The tool's multilingual improvements are real but still center on model training from ByteDance—results may vary by language and prompt complexity. If you're new to video APIs, expect a learning curve with prompt crafting; unlike some consumer tools, KinoviAI doesn't abstract away the need to write clear, detailed prompts. Frame-level editing is powerful but requires understanding which frames matter to your output, which isn't always obvious before generation completes.

Frequently Asked Questions
Seedance 2.5 generates videos from 4 to 30 seconds long. The default duration is 5 seconds, and you can customize it via the duration parameter in the API.
Seedance 2.5 supports text-to-video, image-to-video, multimodal reference generation combining images and video, and audio-driven generation. Auto-detection chooses the mode based on provided inputs.
The API supports resolutions of 480p, 720p, and 1080p. Aspect ratios include 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, and 9:21 for various format needs.
Submit a generation request to receive a taskId. Poll the recordInfo endpoint every 2 seconds until status is success or fail. Optionally provide a webhook URL for automatic completion notifications.
