Short answer
A demo video for Product Hunt is a YouTube link (Product Hunt supports no other video host as of October 2026) placed in your launch gallery. Keep it around 45 to 90 seconds, show the product working in the first 10 seconds, burn in captions because many people watch muted, and back it with at least two 1270×760 gallery images and a square 240×240 thumbnail.
The video is one asset on a busy page. Visitors land from the leaderboard, read your tagline, glance at the gallery, and decide in a few seconds whether to keep going. A demo video for Product Hunt has to earn its place in that glance, which is a different job from the two-minute walkthrough on your website.
This page is about the video and the media around it: specs, length, the opening, captions and the YouTube upload. For the launch itself (timing, hunters, the rules on asking for support, the run-up), read how to launch on Product Hunt.
What Product Hunt accepts for video, gallery and thumbnail
These are the media rules from Product Hunt's own launch preparation guide and its help article on posting a product, as of October 2026. Check them again before you submit, because the submission form changes from time to time.
| Asset | What Product Hunt says | What to make |
|---|---|---|
| Video | Optional. Only YouTube links are supported; use the full URL; the video must not be private | A 45–90 second captioned demo uploaded to YouTube a few days early |
| Gallery images | At least 2 before the gallery shows on the post; 1270×760 recommended; animated GIFs allowed; drag to reorder | 4 to 6 images, each making one point, with large readable text |
| Thumbnail | Required; square, 240×240 recommended, under 3MB; GIFs don't autoplay, so the first frame must work alone | Your logo or one product moment that reads at 240 pixels |
| Tagline | Maximum 60 characters | What it does and for whom, no slogans |
| Interactive demo | Suggested as an option; several demo tools are free for Product Hunt launches | Only if a click-through tells your story better than video |
| First comment | Prompted at submission; can include images, videos or GIFs | A short maker note; link the video again here if it helps |
One number from the same guide is worth knowing: Product Hunt says about 53% of Product of the Day winners since 2021 included a video. That's a correlation, not a promise, but it means a launch without one is competing against a lot of launches that have one.
What the first 10 seconds must do
Most Product Hunt visitors are makers and early adopters scanning a dozen launches. They aren't settling in for a story. If the first 10 seconds are a logo sting, a stock-footage problem montage or a founder saying hello, a good share of them will be gone before your product appears.
- Seconds 0–3: show the product doing its main job. A real screen, mid-action, with the result visible. No logo intro.
- Seconds 3–6: one line of on-screen text naming the outcome in plain words, such as "Invoices chased automatically" for a made-up invoicing app called Ledgerly.
- Seconds 6–10: the moment of difference. The thing a viewer hasn't seen in the five similar tools launched this month.
- After that: two or three short scenes that follow one task from start to finish, then the call to action.
A useful test: mute the video, watch only the first 10 seconds, and ask someone outside the team what the product does. If they can't say it in one sentence, recut the opening before you touch anything else.
How long a demo video for Product Hunt should be
Aim for 45 to 90 seconds. Under 45 and you rarely get past the hook into a real task; past 90 and you're making a tutorial that belongs in your docs. Wistia's analysis of over 13 million videos found that videos under a minute average a 52% engagement rate and that most viewers drop off around the halfway point of longer videos (Wistia), so whatever length you choose, put the product moment early.
At about 140 to 160 spoken words a minute (a rough guide), a 75-second video holds roughly 160 to 190 words of narration. Plan for less, because the screen needs pauses to land. Our video length calculator does the arithmetic for a script you've already drafted.
One video, not three
Teams often want a hype trailer, a feature tour and a founder message. On Product Hunt you get one video slot in practice, and people don't watch two. Put the founder's voice in the first comment instead, where it reads as a maker talking to the community rather than an ad.
Captions, sound and the YouTube upload
Burn captions into the picture. Plenty of people browse launches at work with the sound off, and burned-in text survives whatever player shows your video. Also upload a caption file to YouTube for viewers who prefer closed captions; YouTube Studio lets you upload a subtitle file under Subtitles, and its automatic captions only cover the video's default language. Our guide on how to add subtitles to a video covers SRT and VTT files.
Write the narration so it still makes sense with music only. If a sentence depends on the voice to explain what's on screen, put the key words on screen too.
- Upload to YouTube several days before launch, not that morning, and paste the full youtube.com URL into the gallery. Product Hunt's guide says a private video won't work; public is the safe choice.
- Set a custom YouTube thumbnail. As of October 2026 YouTube asks for a 16:9 JPG or PNG at least 640 pixels wide (it recommends 3840×2160), and custom thumbnails need a verified account.
- Title the YouTube video with your product name and what it does. People who click through to YouTube see that title, and so does YouTube search.
- Export at 1920×1080. The Product Hunt gallery is landscape, so a 16:9 master is the version to link.
Gallery images and thumbnail around the video
The gallery does the work for everyone who never presses play. Treat each image as a slide with one claim and one screen: "Chase late invoices without writing emails" over a crisp view of that screen. Product Hunt recommends 1270×760, so design at that size and keep text big enough to read when the image is shown small.
Order matters because you can drag images into place. Lead with the strongest product screen, then the video or the images that explain the main task, then integrations, pricing or a short customer quote you have permission to use. Keep animated GIFs short and calm; the thumbnail guidance warns against strobing effects and quick cuts, and the same sense applies to the gallery.
The thumbnail is the image people see on the leaderboard, at 240×240. Because GIFs don't autoplay there, the first frame has to stand on its own. A clear logo on a solid color usually beats a tiny screenshot nobody can read.
Recording it, editing it or building it from code
Product Hunt's own guide suggests quick tools like Loom, and for a solo maker shipping a weekend project a tidy screen recording is fine. Script it first, clean the sample data, and record in short takes. Our guide to making a product demo video walks through that order.
If you want motion-designed UI without hiring an animator, DemoVexa builds the video from your app's code: it recreates the real screens as animation, times them to the voiceover and exports a 1920×1080 MP4 with SRT or VTT subtitles, plus 9:16 and 1:1 cuts for the social posts you'll make on launch day. It doesn't make interactive click-through demos, so if a clickable tour is what you want in the gallery, use one of the interactive demo tools Product Hunt lists instead. The tools guide compares the approaches by starting point.
Questions
Is a video required for a Product Hunt launch?
No, the video is optional; only the thumbnail and at least two gallery images are needed for the gallery to show. Product Hunt's launch guide notes that about 53% of Product of the Day winners since 2021 had a video, so most strong launches include one.
Can I use an MP4, Vimeo or Loom link on Product Hunt?
Not as the gallery video: as of October 2026 Product Hunt supports only YouTube links, using the full URL, and the video can't be private. Upload your MP4 to YouTube and paste that link.
Should my Product Hunt video have a voiceover?
A voiceover helps people who turn sound on, but the video must also work muted, so pair it with burned-in captions and on-screen labels. If you can't record clean audio, captions and music alone are better than a muddy voice.
Do I need a vertical version for Product Hunt?
Not for the launch page, which uses a landscape gallery. Make 9:16 and 1:1 cuts for the posts you share on X, LinkedIn and Instagram on launch day, and recompose them rather than cropping the 16:9 master.
Make product videos from your code
DemoVexa reads your app's code, writes the script, adds a voiceover and animates your real screens in 16:9, 9:16 and 1:1. Try it on your own product: 14 days free, no card.
