v0 Portfolio Demo Video

Put a working v0 build in your portfolio instead of a static screenshot.

Show a v0 build running instead of a screenshot, so a portfolio entry proves the thing works rather than describing it.

Choose the job that represents the build

Choose the one job that shows why this build is worth including in a portfolio.

Confirm the preview still works

Open the v0 preview URL and confirm the flow still runs before recording an entry that may sit online for years.

Write the hint and place the clip

Write a hint naming the start, the action and the result, then place the finished clip next to the entry it belongs to.

A portfolio screenshot proves that an interface existed at one moment. It does not prove that clicking the button did anything. A reviewer scanning a list of projects, whether they are a hiring manager, a prospective client, or another builder deciding whether to collaborate, is trying to answer a narrower question than "does this look nice": does this thing actually work. A static image cannot answer that question. A short clip of the real flow can, in less time than it takes to read a project description.

GogoScreen takes a web app URL and a one line hint about what to show, then returns a narrated, edited MP4 with zooms on clicks, cursor smoothing, dead air cuts and burned in captions. For a portfolio entry, that narration matters because it explains what the viewer is watching without requiring a paragraph of context above the clip. The video carries its own explanation, which is exactly what a portfolio entry needs when nobody is standing next to the reviewer to walk them through it.

What makes a v0 build a strong portfolio candidate?

Not every v0 project belongs in a portfolio, and the ones that do are rarely the most visually elaborate. A build that does one specific job well, and can be shown doing it in under a minute, usually reads as more competent than a sprawling app with five half finished sections. Because v0 generates interface quickly, it is easy to end up with several pages that never got real functionality behind them. Pick the entry, and within that entry pick the one job, that survives being watched closely.

Choose the one job that shows why this build is worth including in a portfolio. That might be a generation flow, a transformation from input to output, or a state change the viewer can immediately understand. Avoid choosing a job just because it is the most recently built one. A portfolio is judged over months or years, and the job that best represents the project on the day it was finished is often still the strongest choice much later.

This choice is close to, but not the same as, the one covered in the v0 app review walkthrough guide, which is written for a reviewer confirming a build meets a brief rather than for a portfolio audience deciding whether to hire or hire again. A portfolio viewer is not checking the work against a spec they wrote, they are forming a first impression from almost nothing, so the clip has to carry more of the explanation on its own than a review handoff does.

Portfolio entry quality	What a viewer notices	What to do about it
One job, clearly finished	The flow works end to end	Record exactly that job, nothing more
Several pages, none complete	Gaps between what looks done and what works	Pick the single most finished flow
Interesting idea, thin execution	The concept, not the execution, carries interest	Be honest in the surrounding text, do not overstate the clip

How do you prepare the app for recording?

Open the v0 preview URL and confirm the flow still runs before recording an entry that may sit online for years. A build that worked when it shipped can quietly break weeks later if a dependency changes or a hosted resource expires, and a portfolio entry linked to a broken app undermines every other entry next to it. Check the flow by hand first.

Load the exact route the demonstrated flow begins from and confirm it still opens correctly.
Replace any placeholder content left over from generation with something that looks intentional.
Remove any other person's data, name or account from the build before recording.
If the flow needs a login, use a demo account instead of a personal one.

If a login gates the flow, a demo account can be supplied through the approved process, and the credentials are encrypted, used for a single render, then deleted. When a storyboard is planned first, the credentials are kept encrypted for that session and deleted at most two hours after their last use. For a portfolio entry that might be revisited long after the render, this matters because there is no ongoing access left behind to worry about.

Set aside time for this check even when the build feels finished. A project that sat untouched for months is exactly the kind of entry where a dependency has quietly gone stale, a hosted database has emptied out, or a third party service the app relied on has changed its behavior. Treat the pre recording pass as part of maintaining the portfolio, not as a one time step you complete and never repeat.

How do you write a hint that captures the right moment?

Write a hint naming the start, the action and the result, then place the finished clip next to the entry it belongs to. A hint such as "from the blank editor, generate a component and show it rendered live" is specific enough to produce a usable result. A vague hint like "show the app" risks a render that lingers on navigation instead of the moment that actually demonstrates the build's value.

Keep the vocabulary in the hint consistent with whatever labels the interface actually uses, so the narration reads as a description of the real build rather than a generic summary layered over unrelated footage. The solo developer demo video guide covers a closely related case, where one person is both the builder and the only reviewer before the clip goes public, which is the common situation for a portfolio entry built outside of paid work.

A portfolio also differs from a client deliverable in how forgiving the audience is about scope. A hiring manager scanning many entries will not penalize a project for being small, but they will notice a clip that promises more than the flow actually delivers. Keep the hint's claim exactly as large as the flow it describes, and let the surrounding project description carry any additional context about what the build does not yet do.

Where should the clip live once it is finished?

A clip that only exists as a file on a laptop does no work for the portfolio. The embed product demo video guide covers placing the finished clip directly next to the project description rather than linking away to a separate page, which keeps the reviewer's attention on the portfolio itself. If the entry represents a recent release rather than an older project, the product announcement demo video guide covers framing that distinction so a viewer does not mistake a year old build for a current one.

Roughly one render in five fails or needs a retry, so leave time to watch the candidate before publishing it, and consult the demo video render failure guide if the first attempt does not come back usable. If the build includes any agent driven behavior rather than a purely manual flow, the AI agent browser automation demo guide covers the additional care that kind of flow needs before it goes in front of a reviewer.

For a build made in Cursor instead of v0, the cursor demo video guide, the cursor landing page video guide, the cursor product hunt launch video guide and the cursor share with a client guide walk through the same preparation for a project with no built in preview URL.

Clarifications

Before you start

Why is a video better than a screenshot for a portfolio entry?

A screenshot shows a single frozen state and asks the viewer to imagine the interaction. A video shows the interaction itself, which is usually the part of a portfolio entry that a hiring manager or a client actually needs to see.

Should the portfolio entry show the v0 preview URL?

It does not need to. What matters is showing the app running, not the address it happens to be hosted at while the portfolio version stays live.

How long should a portfolio demo clip be?

Long enough to show one job completed, and no longer. A reviewer looking at a portfolio is usually comparing several entries in one sitting, and a clip that drags loses that comparison before it finishes.
