VideoZen is Artnex’s main AI video studio. You can generate videos from a text prompt alone, or bring an image to life by animating it into a full video clip. With over 11 models from Google, OpenAI, Alibaba, Kling, and ByteDance, you have the right tool for every creative brief — from quick social content to cinematic sequences.

​
Modes

VideoZen offers two generation modes, selectable at the top of the prompt bar.
Write a prompt describing the scene, motion, and style you want. VideoZen sends it to the selected model and returns a video clip. No source image is needed.

​
Generate a text-to-video

1

Open VideoZen

Navigate to Tools > Video > VideoZen in the Artnex sidebar.
2

Select Text-to-Video mode

At the top of the prompt bar, click Text-to-Video to make sure you are in the right mode.
3

Write your prompt

In the text area, describe the video you want to create. Be specific about the subject, setting, camera movement, lighting, and mood for best results.
Use the Prompt Enhancer (the sparkle icon in the prompt bar) to automatically expand and improve your prompt before generation. This works especially well for short or vague descriptions.
4

Choose a model

Click the model selector button in the control bar. A dialog lists all available models grouped by provider. Select the one that fits your quality and budget needs.
5

Adjust settings

Use the aspect ratio, duration, and resolution controls to match the output format you need — for example, 9:16 for vertical short-form content or 16:9 for widescreen.
6

Generate

Click Generate. The credit cost for the selected model is shown next to the button before you confirm. Generation typically takes 30 seconds to 3 minutes depending on the model and duration.
7

Download your video

Once the video appears in your creations gallery, click the Download icon to save it to your device.

​
Generate an image-to-video

1

Switch to Image-to-Video mode

Click Image-to-Video in the mode selector at the top of the prompt bar.
2

Upload a start image

Click Add Image (or Start) in the control bar to upload the image you want to animate. The image becomes the first frame of the video.
3

Optionally upload an end image

For models that support it — including Seedance v1.5 Pro, Kling v2.5 Turbo Pro I2V, and Veo 3.1 I2V — you can also upload an end frame. The model generates the motion that connects the two frames.
4

Write a motion prompt

Describe how you want the image to move or evolve. For example: “The camera slowly zooms in while the flowers sway gently in the wind.”
5

Select a model and settings

Choose an image-to-video capable model from the model selector. Adjust aspect ratio, duration, and resolution to match your intended output.
6

Generate

Click Generate to start the process. Credits are charged once the video is successfully produced.

​
Prompt Enhancer

The Prompt Enhancer is available as a sparkle icon inside the prompt bar. When you click it, Artnex rewrites your prompt with richer descriptive language, camera direction, and cinematic detail before sending it to the model.
The Prompt Enhancer replaces the text in the prompt field with the enhanced version. Review the result before generating so you can adjust anything that doesn’t match your vision.
