See what AI video can do before you build with it
AI video is now cheap enough for product demos, social clips, ads and storyboards, but it's hard to judge a model from sample reels. This page lets you try one yourself with your own prompt.
Free clips are 6 seconds at 480p so they stay free for everyone. For longer, sharper videos open the same prompt in the Grok Imagine playground and generate with credits, or call the model through the HiAPI API.
How to make a free AI video
- 1
Describe the scene
Say who or what is on screen, what happens, the setting and the camera move.
- 2
Pick a format
16:9 for YouTube and websites, 9:16 for Shorts, Reels and TikTok, 1:1 for feeds.
- 3
Generate and continue
Wait about a minute, watch and download, then go longer or sharper in the playground.
What makes a good video prompt
Short clips reward prompts that describe one clear action.
1Subject
a red fox
One main subject keeps the motion clean.
2Action
leaps over a frozen stream
Use one verb the viewer can see. Six seconds is one shot.
3Setting
snowy forest at dawn
Place and time of day set the look.
4Camera
slow tracking shot
Name the move: dolly in, pan, handheld, aerial.
5Light and mood
soft golden light
Light changes the mood more than adjectives.
6Style
cinematic, shallow depth of field
Add a style word or two, not a list.
Ideas to try
Product shots
- A sneaker rotating on a pedestal, studio light, slow orbit.
Nature
- Waves crashing on black rocks at sunset, aerial shot.
Characters
- A robot barista pouring latte art in a cozy cafe.
City
- Neon street in the rain at night, camera moving forward.
Food
- Syrup pouring over a stack of pancakes, close-up, slow motion.
Storyboards
- Block out a scene before shooting or animating it.
Tips
One shot per prompt
Six seconds fits one action. Split longer ideas into several clips.
Describe motion
Say what moves and how fast. Static descriptions give static videos.
Write prompts faster
Use the AI Video Prompt Generator to turn an idea into a shot-by-shot prompt.
Match the platform
Pick the aspect ratio before generating; cropping later loses detail.
Avoid text on screen
Video models still struggle with readable words.
Scale through the API
Batch generate variations through the API once a prompt works.
