Beginner's Guide to AI Video Generation

AI video generation lets you create moving footage from a written description or a single image — no camera, no actors, and no timeline-editing experience. If you have ever stared at a blank editor wondering where to start, this is the shortcut. This guide explains what the technology actually does, what it does well, where it still struggles, and how to make your first video today.

The goal here is not hype. It is to give you a realistic mental model so your first attempts land closer to what you imagined and you waste fewer credits getting there.

What 'AI video generation' really means

There are two main starting points. Text-to-video takes a written prompt — 'a golden retriever running through tall grass at sunset' — and generates a short clip that matches it. Image-to-video takes a still photo you provide and adds motion: a slow camera push, a subject that turns their head, wind moving through a scene.

Both produce short clips, usually a few seconds long. You are not generating a five-minute film in one shot. You are generating shots — building blocks you then arrange, trim, caption, and score into a finished video.

That distinction matters. Treating AI generation as a shot factory rather than a one-click movie maker is the single biggest reason some creators get great results and others get frustrated.

Text-to-video vs image-to-video: which to start with

If you already have a photo you love — a product shot, a portrait, a landscape — start with image-to-video. You keep full control of the look, and the AI only has to add believable motion. Results are more predictable because the composition is already locked. Try it on the image-to-video tool.

If you are starting from an idea in your head with no source image, use text-to-video. You get more creative range, but you trade away some control, so expect to generate a few variations before one clicks.

Most beginners find image-to-video more forgiving for a first win, then graduate to text-to-video once they are comfortable writing prompts.

Writing your first prompt

A good prompt names four things: the subject, the action, the setting, and the style. 'A barista (subject) pouring latte art (action) in a sunlit cafe (setting), shot on film, shallow depth of field (style).' Vague prompts produce vague, generic results; specific prompts give the model something to hold onto.

Describe camera movement explicitly if you want it — 'slow dolly in', 'handheld', 'static shot'. Name the lighting — 'golden hour', 'soft window light', 'neon night'. These words do real work.

Avoid stuffing ten ideas into one prompt. One clear scene per generation beats a crowded description the model has to guess its way through.

From clip to finished video

A raw generated clip is rarely the finished product. The reliable workflow is: generate two or three short shots, pick the best, then assemble them. Add a voiceover or music, layer on animated captions so sound-off viewers can follow along, and export in the aspect ratio your platform wants — 9:16 for TikTok and Reels, 16:9 for YouTube.

Captions in particular are not optional. Most short-form video is watched on mute, so captions are what keep people watching. You can add them automatically once your shots are assembled.

Setting realistic expectations

AI video is remarkable but not magic. Hands, fast complex motion, readable text inside the frame, and perfect physical consistency between shots are still weak spots. Plan around them: favour slower motion, avoid prompts that demand legible signage, and keep individual shots short so small glitches have less time to show.

Think of your first ten generations as learning the tool's dialect. You will quickly develop an instinct for which prompts it renders beautifully and which it fumbles.

Your first project, step by step

Pick one simple idea — a single scene, not a story. Generate it with the AI video generator. Regenerate once or twice to compare. Assemble your favourite, add captions and a short voiceover, and export vertical. That is a complete, publishable clip, and you can do it in a single sitting.

When you are ready to make videos regularly, check the pricing page to see how generation credits work so you can plan your output. Start small, ship something, and iterate — momentum teaches faster than any guide.

Common beginner mistakes

The biggest mistake is expecting a single prompt to hand back a finished, minute-long video. It will not. AI generators produce short shots that you then assemble, caption and score. Once that clicks, most of the early frustration simply disappears, because you stop asking the tool to do something it was never designed to do.

The next tier of mistakes is smaller but just as common. Asking for too much motion causes the melting, warping look people associate with bad AI video — dial it down. Skipping captions loses the large share of viewers who watch on mute. And abandoning a prompt after one weak result wastes its potential: because every generation samples differently, your best take is often the second or third attempt, so regenerate before you rewrite.

Finally, resist the urge to cram an entire story into one prompt. One clear scene per generation, assembled afterwards, beats a crowded description the model has to guess its way through.

A quick glossary

A handful of terms make every AI video tool easier to navigate. A 'prompt' is the text description you feed the model. 'Text-to-video' builds footage from that description alone, while 'image-to-video' adds motion to a still image you provide. 'Aspect ratio' is the shape of the frame — 9:16 vertical for TikTok, Reels and Shorts, 16:9 horizontal for standard YouTube, 1:1 square for some feeds.

'Credits' are how most platforms meter generation: each clip you create spends a certain amount, and longer or higher-quality outputs usually cost more. 'Seed' or 'variation' refers to the randomness that makes each run differ. Knowing this small vocabulary means the settings on any tool — VidMints included — stop looking intimidating and start looking like choices you understand.

How to start today

You do not need a paid plan or a grand strategy to begin. Most creators start on a free tier, spend a few credits learning which prompts land, and only upgrade once they are producing regularly enough that output — not experimentation — is the goal. The pricing page explains how credits map to real output so you can plan sensibly once you reach that point.

The single most useful thing you can do right now is make one small clip end to end: generate a shot, assemble it, add captions, and export vertical. Finishing something — however modest — teaches you more than any amount of reading. It turns AI video from an abstract idea into a skill you actually possess, and it gives you a baseline to improve on with every clip that follows.
