What Does Cospark Do? A Guide to Your First Video Ad

Cospark helps you turn a product, idea, script, or existing footage into an editable video ad. It can write the script, generate scenes, combine them with media you upload, and add voiceover, captions, and music. You can then ask for changes in chat or work on the timeline yourself. That is the workflow described on Cospark's current product page.

You do not have to generate everything. If you already have a good product demonstration, keep it. The useful question is what the ad still needs: a clearer opening, narration, another scene, or an edit that brings the pieces together.

This guide explains where to start, what to prepare, and how to review your first project. Cospark publishes it, so this is a first-party product guide. We checked current public pages on September 4, 2026; the worked example below is an exercise you can adapt, not a reported generation test or a promise of advertising results.

What can you start with?

Choose the input that already contains the most useful work. An approved script saves you from rewriting the argument. Real footage saves you from trying to generate a demonstration you already have. A clean product page can supply the facts, but those facts still need checking.

The app directory also includes a caption workflow. These are entry points for different inputs; you do not need to work through every app to make one ad.

For a URL, use the page for the exact product you are selling. A collection page with several variants gives the agent more opportunities to mix them up. The product-URL guide includes a truth sheet for separating supported facts from assumptions before generation.

Can Cospark use real footage?

Yes. The current product page describes combining generated scenes with uploaded footage, and the editor documentation describes adding clips, swapping scenes, and adjusting timing. You can build around a real product demonstration instead of asking a model to recreate it.

That matters when the action is the evidence. A generated clip of a clamp attaching to a desk may change the screw, jaw, or thickness of the surface. Footage of the real clamp shows what you are actually selling. The same principle applies to software: record the current interface when the ad promises to show how a feature works.

Keep the real proof and use generation where it helps explain or introduce it. If you want to animate a product photo, use the product-fidelity checklist and inspect the resulting frames. A reference image helps direct the shot; it does not guarantee that every label or moving part will stay correct.

Prepare a small first project

Imagine you sell a clamp desk lamp. For this illustrative example, the approved product page says the lamp has three brightness settings, an adjustable arm, and a clamp for desks up to 5 cm thick. It includes a USB cable, while the power adapter is sold separately.

The first ad answers one question: “Will this fit my small desk?” You already have a product photo and a short recording of the actual clamp attaching to a suitable desk. That is enough to plan a useful draft without inventing a customer story or generating a complicated installation scene.

Here is a media plan you can adapt:

An optional generated room shot could introduce the setting. It should not replace the attachment footage or imply that the clamp fits every desk. You may find that the supplied media already tells the story. In that case, ask for assembly, narration, and captions before adding more footage.

Give the agent a brief with a clear boundary

Adapt the details to your own evidence before pasting this into a project:

Create a vertical video ad for our clamp desk lamp.

Audience: people setting up a small desk.
Question to answer: will this lamp fit without a base taking up desk space?

Use the attached wide product photo for the opening, the real clamp recording
for the demonstration, and the approved close-ups for the feature section.
Keep the installation recording as real footage. Do not generate a substitute.

Approved facts:
- three brightness settings
- adjustable arm
- fits desks up to 5 cm thick
- USB cable included; power adapter sold separately

Suggested narration:
"A desk lamp without a base taking up your work surface.
This lamp clamps to desks up to 5 cm thick, with an adjustable arm and
three brightness settings. A USB cable is included; the adapter is sold
separately. Check the fit and current offer on the product page."

Do not claim reduced eye strain, energy savings, universal fit, or a customer
experience. Keep the exact product, clamp, cable, and controls unchanged.

Show me the proposed script and scene plan before generating new media.
Use readable captions and leave the product demonstration easy to see.
End with: "Check your desk fit."

The instruction to show a plan is a request for this project, not a claim that the product enforces an approval checkpoint for every operation. Read the proposed response and check the planned work before proceeding. If the agent needs a missing photo or a clearer instruction, resolve that while the project is still small.

For your own script, the important part is the connection between the line and the asset. If the line says the lamp has three settings, the scene should show the real control or use a clear, approved image. A pleasing room shot cannot establish that feature on its own.

How do you change the first draft?

Ask for a specific change and say what should remain. “Make it better” gives the agent little information about what failed. A useful revision identifies the scene, the problem, and the desired result.

For the lamp example:

In the clamp demonstration scene, shorten the pause before the hand turns the
screw. Keep the original installation footage and its normal playback speed.
Do not change the narration, product close-ups, fit qualification, or closing.
Show me the revised cut so I can check that the attachment remains clear.

Cospark's editor supports conversational revisions and timeline control, but you should still inspect the result. Play the changed section with the scene before and after it. A shorter pause may improve pacing while making the actual attachment harder to follow.

Separate an editing problem from a generation problem. A caption that covers the clamp needs a layout change. A generated clamp with the wrong shape needs replacement, perhaps with the real photo. Rebuilding the entire ad for either issue can disturb material you already approved.

What does Cospark cost?

As of September 4, 2026, the public pricing page lists:

The Free workspace and a Pro trial are different offers. The URL-to-Ad page advertises seven days free, then $25 per month, with a card required. Check the offer, eligibility, allowance, and renewal shown in your checkout before starting a trial.

Credits are a production budget, not a guaranteed number of approved ads. The work required will depend on your project and revisions. Keep a record of what you spent, what you discarded, and what you could actually use before deciding whether a larger plan makes sense.

For a one-off project, that decision may be different from an agency producing repeated client work. Start with a bounded brief and a budget you are comfortable evaluating; a subscription alone cannot tell you how much review your particular product will need.

When is another workflow a better fit?

Cospark is worth considering when the missing work spans scripting, scenes, narration, captions, and ad assembly. If your footage already tells the story and you only need a few cuts, the editor you know may be enough.

Generation and editing are also available elsewhere. Adobe's current Firefly timeline guide describes importing and arranging your own video, audio, and images. Runway's Apps guide includes Edit Studio for manipulating existing footage. An editable workflow is something to evaluate, not a capability unique to Cospark.

Use a real creator when the ad depends on that person's experience. Keep a specialist editor when your project requires detailed post-production or a team workflow already built around that tool. For a broader shortlist, use the AI video tools comparison.

What should you check before exporting?

Watch the whole draft first. Does the opening lead naturally into the demonstration? Can you hear the narration clearly? Does the closing tell someone what to do next? Then pause on the product scenes and check the details against the source material.

For the lamp ad, check that:

• the product, clamp, controls, and included cable match the approved assets;
• the real attachment sequence remains clear and has not been replaced with generated action;
• the script and captions preserve the 5 cm limit and separately sold adapter;
• captions and the crop leave the demonstration visible on a phone;
• the destination shows the same product and current offer;
• you have permission to use the footage, music, voice, and any person's likeness.

An AI presenter can explain the lamp's features. It should not claim to have used the lamp or experienced a benefit without a truthful basis. The FTC's reviews and testimonials FAQ explains that AI avatars are not automatically prohibited, but false underlying testimonials and deceptive presentation remain concerns.

Export is also separate from campaign setup and platform review. For example, TikTok's current misleading-content policy requires disclosure for significantly edited or AI-generated media. Check the rules for the market and placement where you will run the ad. The TikTok workflow guide covers that handoff in more detail.

Start with the assets you trust

Your first Cospark project should answer a small, useful question. Bring the product facts, keep real footage where it supplies the proof, and ask the agent to finish the missing parts. Review one draft and one meaningful correction before expanding the project.

If your script is ready, open Script to Video and adapt the brief above. If the product page is your starting point, use URL to Ad. The first useful result is an ad you understand well enough to approve, edit, and put in front of the right audience.
