AI video generator FAQ
How long does it take to generate a video with AI?
A 5-second HD clip typically renders in one to three minutes on RenderJam. 4K upscaling adds a few more minutes.
Can I use AI-generated videos commercially?
Yes — every paid plan includes a commercial-use license for ads, social content, client work and products.
Is there a free AI video generator?
Yes. RenderJam’s free plan includes 20 credits per month — two 5-second HD videos — with no credit card required.
What makes a good video prompt?
Describe the subject, setting, camera movement, lighting and style — e.g. “handheld close-up of rain on a café window, warm bokeh, cinematic”. Specific prompts produce dramatically better clips.
Do my videos expire?
No. Every render is saved to your personal library permanently, unlike tools where output links expire after a few days.
