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?+
Available models, input types, resolutions and durations are shown in the generator. Options vary by model and can change. Each generation has its own credit quote.
Is it free to use?+
Video generation uses credits. Any promotional credits are subject to eligibility and may not cover a video. Check the quote before generating and see Pricing for current packs.
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?+
Generation time varies with the model, settings and provider queue. Track progress in your task history; there is no guaranteed completion time.
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?+
Choose an available model, test a short clip, and compare the result against your brief. Trying another model creates a separate paid generation.
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.
