Frequently asked questions
Is this AI video generator really free?
Yes — 100% free with no sign-up, no credit card, and no watermark on the video itself. Fair-use limit is 15 videos per day per browser, with a short 2-minute cooldown every 3 generations to keep the service fast for everyone.
What aspect ratios are supported?
16:9 (YouTube / landscape), 9:16 (TikTok, Instagram Reels, YouTube Shorts), 1:1 (Instagram square), 4:5 (Instagram portrait), 21:9 (cinematic widescreen), plus any custom W:H ratio you type in.
How long is each AI video?
Most clips are 3–6 seconds long — perfect for TikTok, Reels, Shorts, ads, and social posts. Chain multiple clips together for longer videos.
Do I need to sign up or install anything?
No. The generator runs directly on FastDailyTools — no account, no download, no Chrome extension. It works on iPhone, Android, and desktop browsers.
Is my prompt or video private?
Your prompt is sent securely to our video model to render the clip. We don't store prompts or videos on our servers.
How do I write a good AI video prompt?
Be specific: subject + camera motion + style + lighting + mood. Example: 'A cinematic drone shot of a snowy mountain village at sunrise, soft golden light, slow forward push, 4K film look.'
Can I use these AI videos commercially?
Generated clips are yours to use for social media, ads, YouTube, TikTok, and client work — always double-check the underlying model's terms before large commercial campaigns.
Why do I have to wait 2 minutes sometimes?
A short cooldown after every 3 videos keeps the free service fast and prevents abuse. While you wait, try our GPT, Claude, PayPal, Etsy, or Solar calculators.
