Most small businesses already have the raw material for good short videos. It sits on the owner's phone: the job half done, the cake before the icing, the van loaded at seven in the morning. What's missing isn't footage or talent. It's a routine that turns twenty random clips into one 20-second reel without eating a whole evening.
This is the workflow I'd suggest to a plumber, a bakery or a hair salon that wants to post short vertical video on Instagram Reels, TikTok or YouTube Shorts. Almost all of it works with nothing but a phone. At the end I'll show how we built the editing part into an AI agent, because that's what we work on, but the steps don't depend on any tool.
1. Film short shots while you work, not "a video"
The mistake is planning a video. Planning means a free afternoon, and a small business never has one. Instead, collect shots: three to eight seconds each, taken whenever something visible happens.
Shots that work for almost any trade:
- Hands at work. Cutting, mixing, fitting, wiring. People like to watch a skill.
- Before and after. Film the "before" even when you're not sure there will be a video. You can't film it later.
- The detail. A close-up of the finished product, the texture, the label, the clean joint.
- The place. Ten seconds of the workshop, the counter or the street outside, so people recognise you.
- One sentence to camera. "This is what a leaking valve looks like" is enough.
Hold the phone vertically, keep it still for a second before and after the action, and face the light rather than having it behind you. Drop every clip into one album. By Friday you have a week of material and nothing to invent.
2. Decide the one thing this video says
Before you cut anything, write one line: what should someone know or feel after watching? "We fix boilers the same day." "This is how our sourdough gets its crust." "Look how this kitchen changed."
One video, one message. If you have two, you have two videos. That line also decides which shots stay: anything that doesn't support it goes, however nice it looks.
3. Cut it short: 15 to 30 seconds, three to six shots
A useful default for a small business reel:
- The first second shows the most interesting thing: the result, the mess, the moment of action. Don't open with your logo or a greeting.
- Three to six shots, each cut to the part where something happens. Trim the dead time at the start and end of every clip.
- End on the result and, if it fits, one practical line: where you are, how to book, what it costs.
Shorter is easier to finish and easier to watch to the end. If you can't decide between two shots, keep the one with movement.
4. Sound, subtitles and music
Assume some people will watch with the sound off, and some with it on. Plan for both:
- Subtitles for anything said, whether it's you talking to camera, a voice-over or a customer speaking in the shot (with their consent).
- A voice-over is often easier than talking to camera. Write it first, read it aloud, and cut it until it fits the video, not the other way round.
- Music only if you have the rights to it. Popular songs belong to someone; the network may mute or remove the video, and the account is yours. Use music you're licensed to use, or music made for you.
- Clean up the sound of a noisy workshop clip, or replace it with music and subtitles.
5. One video, a version for each network
The same vertical video works for Reels, TikTok and Shorts. What should change is the text around it:
- Instagram: a short caption with the one message, and the practical detail (area, booking, price) in the first lines.
- TikTok: a caption that adds context to the video rather than repeating it.
- YouTube Shorts: a title that says what the video shows, in plain words people would search for.
- YouTube or your website need horizontal video, so if you plan to use the same footage there, film a few shots horizontally too.
Choose a cover frame that shows the result, not a blurry moment in between.
6. Be honest about anything AI-generated
If part of the video was generated, whether an AI clip, AI music or an AI voice, say so. Instagram, TikTok and YouTube each have their own labels and rules for AI-generated media, and people accept AI content far more easily when it's labelled than when they discover it. Never use other people's faces, voices or brands without permission, and don't show "customers" who don't exist. Your real work is the most convincing thing you have.
Where an AI agent fits: how we built this into Weyvox
We build Weyvox, a phone app that gives a small business a team of AI agents. One of them, Alice, runs social media, and editing reels is part of her job. Here is how the steps above work there, as a concrete example.
You still film; she cuts. You give Alice your photos and videos, and she edits a reel of up to 90 seconds from them, adding her own clips and sound if you want. Every video you give her is analysed once: scenes, text on screen, what is said and quality problems. She never identifies people.
Subtitles from any voice. A video post gets subtitles from whatever is spoken: her voice-over, your own recording or the people in the frame.
Sound. She makes voice-overs in a library voice (a real person's voice is not offered), music that is instrumental unless you ask for a song, sound effects, and can clean up the sound of a noisy clip.
AI clips only where they help. She can make short AI clips of 3 to 10 seconds, without speech, vertical for Reels, Stories, TikTok and Shorts or horizontal for YouTube and a website, for example starting from a photo of a product, a dish or a storefront. A clip she made can be extended up to 40 seconds within two days. Generated media carries built-in AI marking, and when a post contains AI-made media, the AI label of Instagram, TikTok and YouTube is set automatically. Editing your own footage is not AI content.
You see the real thing before it goes out. She renders a preview in full quality and sends it to the chat as a post card, exactly as it will look on the network. A post from the chat goes out only after you approve it (posts from an approved social media plan follow her Autonomy switch), and once you approve, that very video becomes the final one, without rendering again. The preview itself is not charged.
What it costs. Prices are in credits, where 1 credit = €0.01 excl. VAT; the Start plan is €19 a month excl. VAT and includes 2,500 credits. Editing costs 20 credits per minute of the finished video, at least 10 credits, and watching your videos costs 5 credits per started minute. So a 30-second reel cut from three short videos is 3 × 5 + 10 = 25 credits before any music. A music track is 25 credits, a voice-over 30 credits per started 1,000 characters, and AI clips 30 or 45 credits per second in 720p or 1080p. You pay only for a finished result. The full list is on the pricing page.
The workflow, in short
- Collect three-to-eight-second shots while you work: hands, before and after, details, the place.
- Write one line: what this video says.
- Cut to 15–30 seconds and three to six shots; open with the most interesting moment, end on the result.
- Subtitles for everything said; music only with the rights; clean or replace bad sound.
- One vertical video, a separate caption for each network, and a cover that shows the result.
- Label anything AI-generated, and show only real people, products and places.
The part no tool can do for you is the first one: noticing the moments worth filming. Once that's a habit, the reel is the easy part.
