How to make AI videos for free

Start with a draft, not a masterpiece

The single biggest waste in AI video is rendering a long, high-resolution clip from a prompt you have not tested. Render a fast 360p draft of five seconds first. It tells you whether the camera move, the subject and the mood are what you imagined, and it costs a fraction of an HD render.

The four decisions before you press render

• Prompt — one subject, one action, one camera move
• Format — 9:16 for TikTok and Reels, 16:9 for YouTube and websites
• Length — 5 seconds to test, 8 to 10 seconds to publish
• Quality — draft in fast mode, re-render the keeper in HD

Write the prompt like a shot list

Free tools reward clear instructions. Instead of "a nice city video", write "slow dolly push down a rain-slick city street at dusk, neon signs reflecting in puddles, shallow depth of field". The first prompt gives the model nothing to hold on to; the second gives it a subject, a movement and a light source.

Queue several variations at once

AI video is a numbers game. Queue three variations of the same idea, then keep the steadiest one. In expidvid the queue runs renders back to back and shows you when each one starts, so you can write the next prompt while the first is still rendering.

What to do with the clip

Short AI clips work best as hooks, background plates, product reveals and loops. Publish them vertically for social feeds, or drop a 16:9 clip behind a headline on a landing page. Every clip you render is saved in the gallery with its title and description, so you can revisit what worked.

Common free-render mistakes

• Asking for 30 seconds — consistency collapses; sequence short clips instead
• Two subjects doing two things — the model splits the difference and blurs both
• Crowding the prompt with adjectives instead of one clear camera move
• Cropping a 16:9 render to vertical instead of regenerating at 9:16
