How to make a promo video from text: script-to-video tool, AI clip generator or phone?

You have one offer to promote, maybe a sale or a seasonal package. You have no video of it, and a crew is out of reach. A written description turning into a finished video sounds perfect. It can work, but "text to video" hides two very different products, and picking the wrong one wastes a week and a month of subscription. If your offer repeats every year, see seasonal promo videos you can build in one day.

I will walk through the options from least effort to most, show where Higgsfield fits and where it does not, and give you a plan you can run in seven days with pass and fail marks.

Quick answer: script-to-video tool, clip generator or phone?

• The promo must show your real product, staff or premises: film it on a phone in daylight. Use a script-to-video editor or a normal editor only for captions and music.
• The promo is mostly words, offers and photos: a script-to-video editor or a template tool (Canva, CapCut) is cheaper and faster than any clip generator.
• You need a few scenes that do not exist, such as a mood shot, scenery or something impossible to film: a clip generator earns its place, for those scenes only.

Lilach Bullock, a marketing consultant who sells services of her own, calls text-to-video clip generators "impressive, expensive, rarely the right tool" for most small businesses (page updated October 2026). That is one consultant's view, but the cost math below shows why it is a fair warning.

Two things called text to video

When you search for "make a promo video from text", most of the top results are the first kind below. This page covers both, because you may end up needing each.

Kind	What it does	Example tools	Best for
Script-to-video editor	You paste a script. It picks stock clips or avatars, adds a voiceover and captions, and gives you a rough edit to adjust.	InVideo, and similar editors	Promos built on words, offers and photos
AI clip generator	You describe one scene. A model invents a brand new clip, usually 3 to 15 seconds, with no real footage behind it.	Runway, Pika, Luma (another AI video website), Google Flow, Higgsfield	Scenes you cannot film or buy

A clip generator does not make a finished promo by itself. A 30 second promo is several short clips stitched together, plus your logo, price, voiceover and captions, which come from other tools. That is the part most "type a sentence, get a video" pages leave out.

A promo also needs a structure. One vendor guide names four parts: a hook in the first 3 seconds, the problem the customer has, the solution, and one clear call to action. I use those four as the skeleton below.

The options in order of effort

Start at the top and stop at the first row that does the job. Prices are the vendors' own figures as I read them on 3 November 2026. They change, so check each page before you pay.

Option	What it is	Cost (check the page)	Pick it if
Phone, daylight and a simple editor	You film 3 to 5 short shots yourself and cut them in a free or cheap editor.	Free or close to it	The promo shows something real
Script-to-video editor	A tool such as InVideo that builds a rough video from your script using stock clips.	Check the vendor page	You have the words but no footage
Canva or CapCut with stock	Canva is a design website with video templates. CapCut is a video editor from ByteDance, the company that owns TikTok.	Both have free tiers. Their paid prices were shown in a local currency when I checked, so look at the vendor page	A text-and-photo promo is enough
Runway	An AI video tool that generates clips from text or images.	Free: 125 one-time credits. Standard $15 a month ($12 billed annually) with 625 credits. Pro $35 ($28 annual) with 2,250 credits	You want one model and a simple editor in one place
Pika	An AI video tool aimed at short, playful clips.	Free, but no commercial license. Starter $10 a month with a commercial license	You want a cheap paid entry point
Google Flow	Google's AI video workspace, sold through its AI subscriptions.	Google AI Plus $4.99 a month with 200 Flow credits. AI Pro $19.99 with 1,000. Per-clip credit cost was not stated on the page I read	You already pay for Google's plans
Freelancer or UGC creator	A person who shoots and edits for you.	Ask for a quote	The promo matters enough to pay for a human

OpenAI's Sora (its AI video app) is not an option. OpenAI's help page says the Sora app closed on 26 April 2026 and the API on 24 September 2026. If an older guide tells you to use Sora, it is out of date.

For most small promos, the top rows win on cost. For the broader tool list, see best AI video generators for small business, and for the shot-by-shot choice between AI, stock and filming, see AI video vs stock footage vs filming yourself.

Where Higgsfield fits and where it does not

Higgsfield is a website where you type a description and get back a short clip from a choice of AI video models, such as Seedance, Kling and Veo (video models made by other companies), all inside one account. The pitch is variety: if one model gives you a poor result, you try another without a new subscription. If you want the full picture, read what Higgsfield is and the Higgsfield review.

What it does well for a promo:

• Makes mood and scenery shots you could not film, such as a product on a mountain road, a city at dusk or an abstract background. For cutaways over a talking video, see AI b-roll generators.
• Lets you try more than one model on the same description. Clip lengths run from 3 to 15 seconds on several models, and up to 30 seconds on Seedance 2.5 and Kling 4.0.
• Shows the credit cost on the Generate button before you confirm. A credit is the unit Higgsfield charges, and different models cost different amounts.

What it does not do for you:

• It will not show your real product, shop or staff correctly. A generated clip invents details.
• A Free account has 0 credits, and every generation on a free account carries a Higgsfield watermark, per Higgsfield's help center. A promo you plan to post needs a paid plan.

As of November 2026, Higgsfield's pricing page lists Starter at $19 a month with 270 credits, Plus at $59 a month ($47 billed annually) with 1,200 credits, and Ultra at $129 ($99 annual) with 3,000 credits. Check the current pricing page before you decide, because plans and promotions change. I explain what a month really costs in Higgsfield pricing explained.

Write the script and pick the shape before you open any tool

Every tool works better with a script. Keep it to three lines: the hook (the customer's problem in one sentence), the answer (what you offer), and the action (what to do next and by when). Read it aloud and cut any line you stumble on. InVideo's guide stresses that the hook belongs in the first 3 seconds and that the call to action should lead to a sale, such as "Book a demo", not a vague "visit our website".

Then choose the shape. Vertical 9:16 suits Reels, TikTok and Shorts. Wide 16:9 suits YouTube and a website. Square 1:1 still appears in some feeds. Script-to-video makers such as Pictory (another script-to-video website) list output in all three. With a clip generator, set the shape before you generate, because cropping a wide clip to vertical later can cut off the space you saved for text.

Five steps from one sentence to a finished promo

Step 1: Write the offer in one sentence

Example, made up for illustration: "Spring clean-up packages for homeowners in Austin, book before 30 April and get the first hour half price." If you cannot say it in one sentence, the video will not say it either.

Step 2: Describe three scenes in plain words

Map the four promo parts onto three scenes: the hook and problem, the solution, then the offer and call to action. Keep each scene to one subject, one setting and one camera move. Prompts that pack several actions into one clip fail most often. Use the same style words in all three prompts so the clips cut together.

Copy-ready scene template

Scene 1 (hook): "A tidy garden at golden hour, slow push-in, soft warm light, clear empty space in the upper third of the frame."
Scene 2 (solution): "Close shot of hands pruning a green hedge, shallow depth of field, same warm light, slow pan right."
Scene 3 (offer): "Wide shot of a neat front yard, calm morning light, static camera, clear empty space at the bottom of the frame."

For more starting prompts, see Higgsfield prompts and templates.

Step 3: Generate a few clips and pick the best

Make two or three attempts per scene, and keep notes of which model and words gave the best result. If you decide to try Higgsfield, start on a paid plan for one month rather than a standing subscription, and watch the cost on the Generate button for each model.

Step 4: Add your logo, price and voice in a normal editor

Drop the three clips into a free editor such as CapCut or Canva. Add your logo, the offer text, the phone number or link, a voiceover or music you have the license for, and captions. Most people watch with the sound off, so captions matter.

Step 5: Ask one other person to check it before you post

Do the phone test below. A stranger's reaction beats your own.

What a finished promo costs: keeper-rate math you can replace

Do not judge cost by the price of one generation. Judge it by the price of one clip you actually keep. The formula in plain words: total spend divided by the number of clips that make it into the final video.

Two things push the number up. First, attempts: you rarely keep the first result. Second, edit survival: some clips you keep still get cut from the final edit. One independent reviewer assumes 3 attempts per kept clip and about 70% of kept footage surviving the edit, which multiplies cost by roughly 4.3. Those are that reviewer's assumptions, not measurements. Treat them as a starting guess and replace them with your own numbers after the test.

Worked example with Runway's published numbers (made-up usage, real vendor figures):

• A 30 second promo needs about 6 clips of 5 seconds.
• At 3 attempts per kept clip, that is 18 generations.
• Runway's Gen-4.5 model costs 60 credits per 5 second clip, so 18 generations is 1,080 credits.
• Runway Standard includes 625 credits a month for $15, which covers about 10 clips. So this one promo needs more than one month of Standard.

The same exercise on Higgsfield uses its pricing table, where a 5 second Kling 3.0 clip at 720p is about 7 credits and a 5 second Seedance 2.0 clip at 720p is about 22 credits. For 18 generations that is roughly 126 credits on Kling 3.0 or roughly 396 credits on Seedance 2.0. Seedance 2.5 and Kling 4.0 have no published credit cost, so read the Generate button. These figures can change. See how to spend Higgsfield credits wisely for ways to cut waste.

Neither example counts your time stitching, captioning and checking. A script-to-video editor or a phone often wins once you do.

Keep your logo, prices and phone number out of the generator

AI video models often garble letters and numbers. A price that reads "$49" in your prompt can come back as nonsense. A logo can melt or change shape. Never let the generator draw them. Instead:

• Ask for "clear empty space in the upper third" or "plenty of room at the bottom" so you can place text in your editor.
• Add the logo, price, date and link yourself, over the clip.
• If the product itself must appear accurately, film it. Do not ask a model to invent your product.

Rights, plan licenses and platform labels

This is information, not legal advice. Check local law and each platform's current rules.

• Plan license. Pika's Free plan has no commercial license, while its paid plans do. Runway says it does not restrict commercial use of outputs. For Higgsfield, the pricing table marks commercial use "Not included" for Free, while the help center says use is not restricted to paid plans, and free output is watermarked. Because the two disagree, use a paid plan for client or ad work and screenshot the plan's license line on the day you generate.
• Copyright. The US Copyright Office (the US government body that registers copyrights) said in its January 2025 report that prompts alone do not give enough human control for copyright. So a promo made only from prompts may not be protectable, and a competitor might reuse a similar clip. Your script, edit, overlays and voice are the parts you can own.
• Labels. YouTube asks creators to disclose realistic AI-generated footage. Its own example is AI footage of a real place in a promotional travel video. Clearly unrealistic or animated scenes do not need the label. Rules for Meta and TikTok change, so check each platform's current AI-label setting before posting. Do not write wording that suggests the footage is real.
• Faces and voices. Never use someone's face or voice without their written agreement.

Monthly credit pools reset: Runway's Standard and Pro credits do not roll over, and Higgsfield's subscription credits reset at renewal. For a one-off promo, finish in one month and set a reminder to cancel before renewal.

A seven day test with pass and fail marks

1. Day 1: write the offer and the three scene prompts. Set a hard budget in credits or dollars.
2. Days 2 and 3: generate up to three attempts per scene. Log the model, the credits used and whether you kept the clip.
3. Day 4: assemble the promo. Add logo, price, captions and music.
4. Day 5: run the phone test. Watch it on a phone at arm's length with the sound off. If a stranger cannot say what you sell within 5 seconds, regenerate the hook, not the whole video.
5. Days 6 and 7: post it and note views, saves or enquiries.

Measure	Pass	Fail
Usable shots	At least 4 of 6 shots usable within 3 attempts each	Fewer than 4
Spend	Within your set budget	Over budget
Outside approval	A person outside the business approves it unprompted	They ask what it is or point out errors
Accuracy	Nothing shown is false about your product or place	Any invented detail a customer could notice

If it passes, keep the workflow. If it fails on shots or spend, switch to the script-to-video tool or the phone and cancel the generator before renewal.

Who should skip clip generators

• You sell something where the exact look matters, such as food, clothing, real estate or a medical service.
• You make one promo a quarter. A freelancer or a template is cheaper than a monthly plan.
• You only need text and photos on screen. Canva or CapCut will do that for free, and no generator is needed.

If cost is the worry, read Higgsfield free vs paid and free AI video generators: watermarks, limits and rights before paying for anything.

How I'd approach this

I would film the real parts on a phone first, because customers trust real footage. Then I would use a script-to-video editor or a template tool for the structure, captions and music. Only then would I add a clip generator for the two or three scenes I cannot film, and I would keep each one under a few seconds as a cutaway, not as the whole video.

If you do try Higgsfield, pick one paid month, run the seven day test, and cancel if it fails. The tool is not the hard part. The hard part is repeating the process every week with approvals, a shared library and a record of what was used. If that becomes your problem, Blur Studio builds the repeatable creative workflow, client approval portal or shared asset library around these tools, and you can see how I approach it.
