Video generation on Okou
A few seconds of video from a description or a still, with or without sound. Several video models, no video account of your own.
Generation · No setup · Managed credits per successful call
Describe a shot and get a clip back, a few seconds long, up to high resolution, silent or with sound the model generates itself. Give it a still to start from, or a first and last frame, when the movement matters more than the invention.
Several models are available because they differ in length, resolution, sound and price, and choosing between them is part of the request. Okou holds the accounts and charges each clip in credits, so there is no video generation plan in your name.
What Video generation is
Video generation is now good enough for the short pieces that used to be commissioned or skipped: a few seconds of motion behind a headline, a product moment, an establishing shot in a longer edit.
This is that step as a call. A description, and optionally an image to move or a first and last frame, goes in. A video file comes out, and the agent can hand it straight to the next step rather than to a person with a download folder.
The models are not interchangeable. They differ in how long a clip can run, what resolution they reach, whether they generate their own audio and how references are handled, and the price follows all of that. Naming the model is part of asking.
Compared with buying a video generation plan, the account and the invoice sit with Okou, and access is a permission per agent. Compared with a video editor, this makes footage rather than finished pieces, and the editing is still yours.
What Video generation can do
What an agent can do with it, and what comes back when it does.
Coverage and limits
What it does not do, said up front, so nobody plans a workflow around something that is out of scope.
Seconds, not minutes
A clip runs a few seconds. A longer piece is several clips and an edit, which means planning shots rather than asking for a film.
It is the most expensive call here
Video is charged by the second or by the amount of picture generated, and resolution and sound both raise it. Drafting at a low resolution before committing to the final render is the difference between a sensible bill and a surprising one.
Rendering takes real time
Clips take minutes rather than seconds to come back, so a workflow that generates several should expect to wait, and a person watching a chat should be told what is happening.
Not precise about details
Exact wording, exact logos, exact faces and exact product shapes are where generated video still gives itself away. Anything that has to be exact belongs as an overlay on top of the footage.
What Video generation costs
Web services are billed in credits per call, not per token. There is no separate vendor bill to reconcile.
MiniMax, BytePlus and fal.ai modelszero generate videoCharged in credits per clip, based on the model, the length, the resolution and whether the clip has sound. It is the most expensive service in this catalog by some distance, which is why the model and the resolution are worth naming in the request rather than leaving to a default.
Product names and logos belong to their owners and appear here only to say what a service runs on. They do not imply any endorsement or partnership.
Setup and access
Nothing to set up
Nothing to connect. No video model account, no key, no plan. If you already pay a provider and want the usage on your own account, Okou ships connectors for several of them; the built-in service is for when you would rather not have the account at all.
Who can use it
Generating a file is a permission you grant per agent and per person. Given what video costs, it is worth granting narrowly and to the agents that were built for it.
What teams use Video generation for
Short motion for something already written
A launch post, a changelog entry, a social card. The agent that writes the words can produce three seconds of motion to go with them instead of shipping a static image.
Bringing a still to life
A product photo or an illustration you already own, given a small amount of movement, is usually more useful and more on-brand than a clip invented from nothing.
Filling gaps in a longer edit
An establishing shot or a transition that nobody wants to film. Generate the few seconds that are missing and cut them into the piece you already have.
When not to use Video generation
Skip it when the piece has to say something exactly, and put the words on top in an edit. Skip it for anything longer than a few seconds as a single call, because that is several clips and a plan. And skip it as a default step in a frequently scheduled workflow, where the cost adds up faster than anyone reviews the output.
What this is called elsewhere
The same thing goes by several names in the market. If you have shopped for one of these, this is how it maps to what you get here.
Text to video API
A description in, a video file out, over an interface a program can call. That is this, with the accounts and the keys on our side.
Image to video API
Starting from a still and asking for movement, which is the version most teams actually want because the subject is already theirs.
AI video generator without an account
No signup, no key, no monthly plan. You ask in a message and the file comes back, charged per clip in credits.
AI b-roll
Short filler footage for an edit. Generated clips are good at exactly this and poor at anything that has to be precise.
Talking avatar video
A related but different job: a presenter reading a script, produced from an avatar and a voice rather than from a description of a scene. Okou generates those too, through the same command family.
Video generation compared
Video generation vs a video model account of your own
Same models, different admin. On your own it is an account and a key per provider and a bill each, and trying a different model is an integration. Here the model is named in the request and the usage lands on one credit line.
Video generation vs a video editor
An editor assembles, times and captions. This produces raw footage. The good workflow is this for the shots nobody can film and an editor for everything that decides what the piece says.
Video generation vs stock footage
Stock is cheaper, licensed and safe, and it looks like stock. Generation earns its cost when the shot has to be about your specific thing, or when it does not exist.
The short version
Short generated footage for workflows that already produce the words. Draft small, name the model, and keep anything that must be exact as an overlay rather than a prompt.
Frequently asked questions
Do I need a video model account?
No. Okou runs the generation and charges it in credits. There is no provider account, key or plan on your side.
How long can a clip be?
A few seconds, with the exact maximum depending on the model. Longer pieces are several clips and an edit.
Can it start from an image?
Yes. A reference image, and on some models a first and last frame, which is the most reliable way to get movement you can predict.
Does it produce sound?
Some models generate their own audio and some are silent. Sound generally costs more, so it is worth deciding rather than defaulting.
What does a clip cost?
Credits per clip, driven by length, resolution, sound and the model. It is the most expensive service in this catalog, and a low-resolution draft first is the usual way to keep it sane.
How long does it take?
Minutes rather than seconds. A workflow that generates several clips should be built to wait, and to say so to whoever is watching.
Can I put text in the video?
Not reliably from a prompt. Generate the footage and add the words in an edit, where they will be correct every time.
Can it make a presenter talking to camera?
That is the avatar video path rather than this one: a script and a chosen avatar and voice, produced through the same command family and charged the same way.
How you ask for Video generation
You describe what you want in plain language. The agent works out which service it needs and makes the calls.
“Make a six-second silent clip of a paper plane flying over a city at golden hour, at 1080p, and give me the file.”
“Take this product photo and give me four seconds of slow push-in, no sound, nothing else moving.”
“I need three seconds of empty office at dawn to cut between two interview clips. Draft it small first so I can check the look.”
