AI Video Generator FAQs
Answers to common questions about producing videos with prompts and optional images.
Do I need to upload an image to generate a video?
No. You can create a clip using only a text prompt. Adding a reference image is optional and helps the AI lock onto a specific composition.
What file types and sizes are supported if I include an image?
We support JPG, JPEG, PNG, WebP, and GIF files up to 24MB. Higher-resolution images (minimum 1024x1024) provide more detail for depth analysis.
How long does rendering usually take?
Most clips are ready in one to five minutes depending on duration, resolution, and current demand. Premium plans receive priority processing.
How do I control the motion and visual style?
Use descriptive prompts to specify camera moves, pacing, mood, lighting, effects, or animation styles. You can refine and regenerate at any time.
What resolutions and aspect ratios can I export?
Choose between HD (720p/1080p) and 4K, with aspect ratios including 16:9, 9:16, and 1:1 so every video is ready for its intended platform.
What is the maximum duration right now?
The generator currently supports clips up to 12 seconds. Longer sequences are on the roadmap.
Are outputs watermarked?
Free tier exports include a subtle watermark. Paid plans remove watermarks and unlock additional export controls.
Can I use generated videos commercially?
Yes. Commercial rights are included with paid plans for marketing, client projects, ads, and monetized channels. Free plans are limited to personal use.
