Subject, setting, camera, action, spoken line, tone — in that order — produces far more usable footage than a paragraph of adjectives. - Hook decides everything. The first 1.5 seconds carries most of the retention outcome, so generate five hooks per concept and keep the body identical. - Export 9:16 for TikTok, Reels and Shorts, 4:5 or 1:1 for feed, 16:9 for YouTube — with burned-in captions, because most views start muted. - AI-generated or AI-altered video must be labelled on TikTok, YouTube, Instagram and Meta. Labelling does not measurably hurt performance; fake testimonials create real legal risk. - Realistic 2026 economics: roughly $2 to $8 per finished, captioned, multi-ratio AI video versus $150 to $400 for a commissioned human UGC clip. Generating a social media video with AI is no longer a novelty workflow — in 2026 it is the default way small teams keep a posting calendar full. But most people get thin results because they treat the generator like a search box: they type a sentence, accept the first render, and post it. The gap between a clip that looks synthetic and one that performs is almost entirely in the inputs. This guide is the actual step-by-step process: what to decide before you generate, how to structure the prompt, how to ground the output in your real product, how to iterate on hooks, and how to export and publish so each platform treats the video well. Everything below assumes you are one person with a product and no film crew. ## Step 1 — Decide what job the video has to do Before any prompt, name one job. A video that tries to introduce your brand, explain a feature and drive a signup will do none of them. In practice there are four jobs worth generating for on social: - Hook test — one idea, 8 to 15 seconds, judged only on 3-second retention. Cheapest to generate, most informative. - Product explainer — 20 to 30 seconds showing what the thing does, with the real interface or packaging on screen. - Social-proof style testimonial — a creator-style presenter describing a benefit. Never present a synthetic presenter as a verified customer. - Offer or launch — a dated reason to act now, usually a remix of a hook that already won. ## Step 2 — Write the prompt in a fixed structure AI video models respond to structure, not enthusiasm. Use the same six-slot template every time so you can change one variable and attribute the difference: Subject → Setting → Camera → Action → Spoken line → Tone. A working example: "A woman in her late twenties, casual cream sweater, in a bright apartment kitchen. Handheld phone-style selfie framing, 35mm look, slight natural movement. She holds up a matte white skincare bottle, turns it toward the lens, then applies a small amount. She says: 'I stopped buying three products when this one replaced all of them.' Tone: unpolished, conversational, no music." Notice what is absent: no adjectives like 'amazing' or 'cinematic masterpiece', no stacked style words. Concrete nouns and physical actions generate reliably; vibe words generate noise. - Name one subject only — extra people multiply artefacts. - Give the camera a real reference (handheld selfie, tripod mid-shot, 35mm) instead of 'high quality'. - Write the spoken line verbatim, under 25 words for an 8-second clip. - State what should not be there: no music, no text overlay, no on-screen logo, if you plan to add those in post. ## Step 3 — Ground the video in your real product This is the step that separates AI video that converts from AI video that gets scrolled. A fully synthetic clip about a generic product performs poorly because nothing on screen is verifiable. Feed the generator your actual material: a product URL so it can read your positioning and pull imagery, screenshots of your app or site, your logo, and photos of the physical product. For software especially, the strongest structure is a presenter hook for the first three seconds, then a cut to a real screen recording or screenshot sequence for the middle, then a spoken close. The AI carries the parts that are expensive to film; your real assets carry credibility. ## Step 4 — Generate five hooks, not five videos The first 1.5 seconds decides most of the retention outcome, so spend your generation budget there. Keep the body of the script identical and vary only the opening line and opening frame. Five hook formulas that consistently earn a watch: - Contradiction — "Skincare hype? No. Here's what actually changed." - Cost or number — "I replaced a $400 creator shoot with this in nine minutes." - Problem in one breath — "If your ads all look the same, this is why." - Demonstration first — start on the product doing the thing, speak second. - Direct address to a segment — "If you run a Shopify store under $50k a month…" ## Step 5 — Caption, export and publish per platform Most social video views start muted, so burned-in captions are not optional — they are the script. Then export the ratio each surface actually wants rather than uploading one file everywhere and letting the platform crop your subject's face off. - TikTok, Instagram Reels, YouTube Shorts — 9:16, 1080×1920, keep text inside the middle 80% to clear UI overlays. - Instagram and Facebook feed — 4:5 or 1:1; 4:5 takes more screen height. - YouTube in-stream and display — 16:9, 1920×1080. - Captions burned in, high contrast, no more than six words per line. - Keep the first frame visually loud — it is your thumbnail on most surfaces. ## Step 6 — Disclose AI, and keep claims defensible TikTok, YouTube, Instagram and Meta all require AI-generated or AI-altered content to be labelled, and each provides an in-app toggle. Use it. Across tested accounts, disclosure has no meaningful measured effect on performance — what does create exposure is presenting a synthetic presenter as a real customer, or putting a number on screen you cannot evidence. The safe pattern: label the video, describe benefits your product genuinely delivers, and reserve real testimonials for real customers filmed on a real phone. ## What this costs in 2026 A commissioned human UGC video runs $150 to $400 with one to two weeks of turnaround, plus briefing and revision overhead. Generating the same length of finished, captioned, multi-ratio video with AI lands between roughly $2 and $8 depending on render quality tier — which is what makes hook testing viable at all. You are not replacing one video with one video; you are replacing one video with fifteen tested variations. Budget by variations, not by clips. A useful weekly cadence for a solo operator: ten hook tests on Monday, keep the two with the best 3-second retention, generate three body variations of each on Wednesday, and publish the winner across all placements on Friday. ## Common mistakes that make AI video look AI - Prompts full of style adjectives and no physical action. - Clips longer than about 10 seconds per generation — drift and mouth-sync errors compound in the final third. - No real product on screen anywhere in the video. - Music over a talking-head hook, which buries the line that does the work. - Publishing one 16:9 file to every surface. - Regenerating a losing concept instead of changing the hook. ## FAQ ### How do you generate a social media video with AI? Decide the one job the video has to do, write a structured prompt covering subject, setting, camera, action, spoken line and tone, ground it with your product URL, screenshots or logo, generate five hook variations with an identical body, then export 9:16, 4:5 and 16:9 with burned-in captions and label the video as AI-generated when you publish. ### What is the best prompt structure for AI video? Subject, setting, camera, action, spoken line, tone — in that order. Concrete nouns and physical actions generate reliably; style adjectives like 'cinematic' or 'amazing' add noise. Write the spoken line verbatim and keep it under 25 words for an 8-second clip. ### How long should an AI-generated social media video be? Eight to fifteen seconds for hook tests and twenty to thirty seconds for explainers. Generate in short segments rather than one long clip, because mouth-sync drift and motion artefacts compound in the final third of longer generations. ### Do AI-generated social videos need to be labelled? Yes. TikTok, YouTube, Instagram and Meta all require AI-generated or AI-altered content to be disclosed and provide an in-app toggle. Labelling has no meaningful measured effect on performance, while fabricated testimonials or unsupported claims carry real risk under FTC endorsement guidance. ### How much does it cost to generate social media videos with AI? Roughly $2 to $8 per finished, captioned, multi-aspect-ratio video in 2026, depending on render quality tier, versus $150 to $400 and one to two weeks for a commissioned human UGC video. ### Can AI generate videos for TikTok, Reels and Shorts at once? Yes — a capable platform renders once and exports 9:16 for TikTok, Reels and Shorts, 4:5 or 1:1 for feed placements, and 16:9 for YouTube, with captions burned in. Single-ratio export should be treated as a disqualifier when choosing a tool. ## Sources - [TikTok — AI-generated content disclosure](https://support.tiktok.com/en/using-tiktok/creating-videos/ai-generated-content) - [YouTube — disclosing altered or synthetic content](https://support.google.com/youtube/answer/14328491) - [Meta — ads guide and video specifications](https://www.facebook.com/business/ads-guide) - [US FTC — endorsement and testimonial guides](https://www.ftc.gov/business-guidance/resources/ftcs-endorsement-guides-what-people-are-asking) - [Google Search Central — helpful, people-first content](https://developers.google.com/search/docs/fundamentals/creating-helpful-content) ## Featured pick ### Generate your first social video with VydioFlow.com VydioFlow runs every step above in one pass.
