Everything you need to know about generating AI videos on ZNIX.ai.
What is an AI video generator?+
An AI video generator is a tool that creates video clips from text descriptions (text-to-video) or reference images (image-to-video) using artificial intelligence models. You describe the scene you want — subject, camera movement, lighting, mood — and the AI renders a matching video clip. No filming, no editing software, no motion graphics skills required.
How many AI models does ZNIX.ai offer?+
ZNIX.ai offers 10+ AI video models in one workspace, including Seedance 2.0 (ByteDance), Kling 2.0 (Kuaishou), Wan 2.1 (Alibaba), Vidu 2.0 (Shengshu), HunyuanVideo (Tencent), MiniMax Video, Luma Ray2, and Pika 2.2. You can switch between models freely without separate subscriptions or accounts.
Is it free to use?+
Yes, you get free credits when you sign up — enough to generate your first batch of videos at no cost. Paid plans start under $20/month and unlock higher resolution, longer durations, parallel render queues, and priority access to new models. Compared to stock video ($5-50/clip) or video production ($500+/video), the cost per video is typically 90-95% lower.
What is the difference between text-to-video and image-to-video?+
Text-to-video generates a video from a written description ("slow pan across a mountain lake at sunrise"). Image-to-video takes an existing image as input and extends it into motion — the AI preserves the visual identity of the image while adding camera movement and animation. Image-to-video is better for brand consistency; text-to-video is better for creative exploration.
What aspect ratios and resolutions are supported?+
The generator supports all major aspect ratios: 9:16 (vertical, for TikTok/Reels/Shorts), 16:9 (horizontal, for YouTube/pre-roll), 1:1 (square, for Instagram/Facebook feed), and 4:3 (for presentations). Resolution options include 720p for fast previews and 1080p for final output. Not all models support all resolutions — the interface shows available options per model.
How long does generation take?+
Most videos generate in 30-90 seconds depending on the model, duration, and resolution. Kling is the fastest (under 30 seconds for 720p). Seedance takes longer but produces the highest-quality output. You can queue multiple generations and work on other tasks while they render.
Can I use the videos commercially?+
Yes. All videos generated on ZNIX.ai are fully licensed for commercial use — ads, social media, client work, product pages, presentations, and any other business purpose. You own the output. No additional licensing fees or attribution required.
What is keyframe control?+
Keyframe control lets you set a start image, end image, or both. The AI generates the motion between them — controlling the camera path, subject transformation, and scene evolution. This gives you directorial control over the output rather than relying entirely on the AI's interpretation of a text prompt. Available on Seedance, Kling, and Wan models.
Which model should I choose?+
It depends on your goal. Seedance 2.0 for highest quality cinematic output. Kling 2.0 for fastest iteration and drafting. Wan 2.1 for complex multi-subject scenes. Vidu 2.0 for stylized/artistic looks. MiniMax for longer clips. Luma for fluid physics-aware motion. Pika for special effects. Try the same prompt across 2-3 models to find the best fit for your content.
How is this different from the AI Video Agent?+
The AI Video Generator is a direct prompt-to-video tool — you type a description or upload an image and get a video. The AI Video Agent is a workflow automation tool that handles the full production pipeline: upload reference media, auto-generate scripts, and render publish-ready videos. Use the Generator for quick, single-shot video creation. Use the Agent when you need scripted, multi-step production workflows.
