A practical, step-by-step walkthrough of making a video with AI tools, starting from the script and ending with a published file. Covers the five-stage pipeline (script, voice, visuals, assembly, polish), which tools do what, why your prompt matters less than your shot list, and the mistakes that make AI video look obviously AI.
The five stages, and what AI actually does in each
Making a video with AI is still making a video. The pipeline has not changed: script, voice, visuals, assembly, polish. What changed is that four of those five stages now have a software shortcut, and the fifth (assembly) is where you still do real work.
Here is the honest division of labour. AI writes a decent first-draft script and a weak final one. AI voice is now good enough that most viewers will not notice, provided you fix the pronunciation of names and numbers. AI visuals are excellent for b-roll and abstract shots, unreliable for anything with hands, text on screen, or a character who must look the same in shot 3 and shot 11. Assembly is manual. Polish is half manual.
Beginners usually get this backwards. They spend two hours prompting a video model for a six-second clip and ten minutes on the script. Then they wonder why the video does not hold attention. The script is the part that decides whether anyone watches to the end. Everything downstream is decoration.
| Stage | What AI does well | What you still do |
|---|---|---|
| Script | First draft, hook variations, restructuring | Cut 30%, add a real example, fix the ending |
| Voiceover | Natural-sounding narration in one take | Pronunciation fixes, pacing, re-record bad lines |
| Visuals | B-roll, abstract shots, stylised scenes | Shot list, continuity checks, rejecting bad gens |
| Assembly | Auto-cut silences, rough sync | Timing, cutaways, rhythm, the actual edit |
| Polish | Captions, music matching, upscaling | Colour, caption accuracy, final watch-through |
Start with the script, and write it for the ear
Open a chat model and give it three things: the topic, the length in seconds, and who it is for. Not "write a video about AI in healthcare". Try "90-second explainer for a non-technical hospital administrator on why AI scribes reduce doctor burnout, open with a specific daily frustration". The second prompt gives you something usable.
Then edit it hard. AI-written scripts have a signature rhythm: every sentence is the same length, every paragraph has three points, and the conclusion restates the intro. Read your draft out loud. Anywhere you stumble, rewrite. Anywhere you get bored, cut.
One technique that fixes most beginner scripts: write the first eight seconds last. Finish the body, then go back and write a hook that promises exactly what the body delivers. Most weak videos fail here, not in the visuals.
Finally, break the script into shots before you touch any video tool. One line of narration, one visual idea, on separate rows. This document is your shot list, and it is the difference between a two-hour edit and a two-day one.
Voice before visuals, always
Generate your voiceover next, not your visuals. The audio track sets the exact duration of every shot. If you make visuals first, you will be stretching and trimming clips to fit narration that did not exist yet, and it will show.
For voice, the usable options in 2025 are ElevenLabs, Murf, and the built-in voices in most editing suites. Paste the script, pick a voice, generate. Then listen with headphones. AI narrators mangle Indian names, acronyms and large numbers fairly often, so you will spend ten minutes fixing those by spelling the word phonetically in the input (write "Ben-ga-loo-roo" if the model keeps saying something odd). Insert commas and line breaks to force pauses. That is almost all of the craft.
If you are narrating yourself, do it now anyway. Same reason. Audio first, picture second.
Visuals: match the tool to the shot, not to the hype
There is no single best AI video tool, and chasing one is how beginners lose weeks. Different shots need different machines.
For talking-head explainers with no camera, HeyGen and Synthesia give you an avatar reading your script. Fast, professional, slightly uncanny. For cinematic b-roll, Runway, Kling, Luma and Google's Veo generate clips from a text or image prompt. For faceless content built on stock footage and text overlays, a plain editor plus a stock library often beats generation entirely, and costs nothing.
The practical rule: generate only the shots you cannot get otherwise. A clip of rain on a window does not need a diffusion model. A dragon made of circuit boards does.
Two things will frustrate you early. First, consistency. If a character appears in multiple shots, generate from a single reference image rather than a fresh text prompt each time, and accept that minor drift is normal. Second, text. AI video models still produce garbled words on signs and screens, so add any on-screen text in your editor afterwards.
A working prompt structure that holds up: subject, action, camera movement, lighting, style, duration. "A woman in a white lab coat examines a sample, slow dolly in, soft morning light through blinds, documentary style, 5 seconds." Vague prompts give vague clips.
- Plan for roughly a 1 in 4 hit rate on generated clips. Budget generations accordingly.
- Generate at the aspect ratio you will publish in. Cropping 16:9 to vertical ruins framing.
- Keep every usable clip, even rejected ones. They become cutaways during the edit.
- Five to eight seconds per shot is the sweet spot. Longer clips degrade and look loopy.
Assembly and polish: where the video actually becomes good
Drop the voiceover into your timeline first. CapCut, DaVinci Resolve and Premiere all work, and CapCut is free and fast enough for most beginners. Lay the audio across the full timeline, then place each visual against the line of narration it belongs to.
Now cut. The rule that improves almost every beginner edit: change the picture every three to five seconds, even if the narration continues. Our eyes get restless faster than our ears do. Cutaways, zooms and a held frame with a text overlay all count as a change.
Add captions, because a large share of viewers watch muted. Auto-captions are close but not correct, so read them once and fix the technical terms. Add music at roughly 15 to 20 percent of voice volume, and duck it further under narration. Then watch the whole thing once at normal speed without touching anything. You will spot two or three timing problems you missed while editing.
If you are publishing to YouTube, label AI-generated content honestly in the upload settings. The disclosure rules are worth reading once before you build a channel on this, and we cover them in detail in the YouTube AI video rules guide.
Your first video will take six hours and look mediocre. Your fifth will take ninety minutes and look fine. That gap is practice, not tools, which is also why reading about this pipeline only gets you so far. If you want to run it end to end with feedback on your actual output rather than guesswork, the AI Creator Fellowship is built around shipping projects over eight weeks instead of collecting tutorials. Either way, make the video this week. The second one is where it starts getting interesting.
FAQs
1. How much does it cost to make an AI video as a beginner?
You can produce a basic narrated video for free using CapCut, a free-tier voice tool and stock footage. Once you add AI video generation and a paid voice plan, expect roughly 1,500 to 4,000 rupees a month across two or three subscriptions, and more if you generate heavily.
2. Which AI video tool should I start with if I can only pick one?
Start with a text-to-speech tool plus a normal editor like CapCut, not a video generator. That combination covers explainers, faceless content and most short-form formats, and it teaches you editing, which is the skill that transfers everywhere.
3. Can AI make a full video from just a script in one click?
Tools like Pictory, InVideo and Synthesia will generate a complete video from a script automatically. The output is passable for internal or informational content, but it is generic, and anything meant to compete for attention still needs a human edit.
4. Why do AI-generated videos look obviously fake?
Usually three giveaways: hands and faces that shift between frames, garbled text on signs or screens, and shots that run too long so the motion starts looping. Keeping clips under eight seconds and adding text in your editor fixes most of it.
5. Do I need to tell viewers my video was made with AI?
On YouTube you must disclose realistic synthetic content that could be mistaken for real people, places or events in the upload settings. Clearly stylised or animated AI content generally does not require the label, but the rules are platform-specific and worth checking before you publish.
6. How long does a one-minute AI video take to make?
For a first-timer, around four to six hours, with most of that spent regenerating visuals and learning the editor. After ten or so videos, the same minute takes 60 to 90 minutes, because the script and shot list stop being guesswork.
