How it works

From prompt to publish-ready video in three steps

Most users get their first video in under 90 seconds. No editing timeline, no manual setup — describe, pick a model, render.

3 steps · ~60 seconds
01
Describe

Type a prompt or upload an image

Describe the scene you want — camera movement, lighting, mood, subject. Or upload a reference image and let the AI extend it into motion. Supports text-to-video and image-to-video in the same composer.

02
Model

Pick the right AI model

Choose from 10+ models based on your goal: Seedance for realism, Kling for speed, Wan for complex scenes, Vidu for stylized looks. Set aspect ratio (9:16, 16:9, 1:1), duration (5–10s), and resolution (720p–1080p).

03
Render

Render and download

Hit generate. The AI renders your video in 30–90 seconds depending on model and duration. Preview in-browser, download as MP4, or regenerate with a different model or tweaked prompt. Your generation history is saved for easy iteration.

Capabilities

Everything you need to generate AI video — nothing you don't

Text-to-video, image-to-video, keyframe control, multi-ratio output, batch rendering, and commercial licensing. All built into one workspace.

✦

Text to Video

Type a natural-language prompt and the AI generates a matching video clip. Describe scene, camera angle, lighting, mood, and subject — the model interprets and renders. Works across all 10+ models.

◈

Image to Video

Upload a reference image — product photo, illustration, screenshot — and the AI extends it into motion. The model preserves composition, color palette, and subject identity while adding cinematic movement.

▥

Keyframe Control

Set a start frame, end frame, or both. The AI generates the motion between them — controlling camera path, subject transformation, and scene evolution. Available on select models (Seedance, Kling, Wan).

⊞

Multi-Ratio Output

Render in any major aspect ratio from a single prompt: 9:16 for TikTok/Reels/Shorts, 16:9 for YouTube, 1:1 for Instagram feed, 4:3 for presentations. Switch ratios without re-prompting.

◉

HD Resolution

Generate at 720p for fast previews or 1080p for final output. Resolution options vary by model — Seedance and Kling support full 1080p, others optimize at 720p for speed.

⧉

Batch Generation

Queue multiple generations with different prompts, models, or settings. Run them in parallel and compare results side by side. Paid plans unlock higher concurrency for bulk workflows.

Use cases

Who uses an AI video generator — and what they build

From social media creators to enterprise marketing teams, the workflow is the same: describe what you want, pick a model, render. The use cases are as varied as the people.

Creator

Content creators — produce more, outsource less

Generate b-roll, intros, transitions, and visual hooks without a camera or editing suite. Test ten visual concepts in the time it used to take to film one. Post to TikTok, YouTube, or Instagram directly from the download.

Marketer

Marketers — video ads at the speed of copy

Turn a product brief into a video ad variant in under two minutes. A/B test visual styles across Seedance (cinematic), Kling (fast), and Vidu (stylized) without reshooting. Export in 9:16 for social, 16:9 for pre-roll, 1:1 for feed — from one prompt.

Educator

Educators — visual explanations without production budgets

Generate explainer animations, concept visualizations, and lecture intros from text descriptions. No motion graphics software required. Particularly useful for abstract concepts (molecular biology, physics, history) that are hard to film.

Business

Business teams — internal video without the agency

Create product demos, training clips, onboarding videos, and presentation visuals in-house. No creative brief, no agency timeline, no revision cycles. Generate, review, publish — same day.

Personal

Personal projects — bring ideas to life for fun

Generate music video concepts, short film scenes, social media content, birthday greetings, or just explore what AI video can do. No professional goal required — curiosity is enough.

Field guide

Six rules for getting great results from AI video generators

Practical, tested advice for generating videos that actually look good — not just passable in a preview thumbnail.

01

Be specific about camera and lighting

Vague prompts produce vague videos. Instead of "a person walking," try "medium tracking shot of a woman walking through a Tokyo alley at dusk, neon reflections on wet pavement, shallow depth of field." Camera angle, movement type, and lighting conditions are the three highest-leverage details you can specify.

02

Match the model to the mood

Seedance renders the most photorealistic output — use it for product shots and brand content. Kling is fastest for iteration. Vidu handles stylized looks (anime, clay, watercolor). MiniMax handles longer sequences. Don't use a speed model when you need cinema, and don't use a cinema model when you need fast drafts.

03

Start short, then extend

Generate 5-second clips first to validate your prompt and visual direction. Once you find the right look, extend to 10 seconds or switch to a higher-quality model. This saves credits and time — most prompts need 2-3 iterations before they hit.

04

Use image-to-video for brand consistency

When you need the output to match existing brand assets — a specific product photo, color palette, or visual style — start with image-to-video instead of text-to-video. Upload your reference image and the AI preserves its visual identity while adding motion.

05

Keyframes give you directorial control

Set a start frame and end frame to control the exact transformation you want: product rotating from angle A to angle B, scene transitioning from day to night, object morphing from one state to another. This is the closest you get to directing the AI's camera.

06

Compare models on the same prompt

The same prompt can produce dramatically different results across models. Generate the same scene with Seedance, Kling, and Wan — compare realism, motion quality, and rendering speed. You'll quickly develop intuition for which model fits which type of content.

AI Video Generator — Frequently Asked Questions

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.
