What video to put on your company website, and how to add it without slowing it down

What video to put on a company website, and on which page

The question isn't whether to use video, but which one and where. Each page on a website has a different job, and the video has to help with that job, not decorate it.

On the home page, visitors want to understand what you do within a few seconds. Two things fit there: a short silent loop that shows your work or your space, and a one- or two-minute company video for anyone who wants to know more. What that video should say is covered in how to make a company presentation video.

On service or product pages, the video shows the thing working: the machine running, the service from start to finish, the before and after. This is where video does the most to help people decide.

On case studies, what convinces is a client explaining what changed, in their own words. On the careers page, the real team at their real workplace, which says more than any list of perks. And on the about or contact page, a face: the person who will pick up the call.

If you have nothing yet, start with the home page and the service you sell most. That's where the traffic is and where the difference shows.

Is a background video on the home page a good idea?

It can be, if you treat it as what it is: a background that informs, not a video to watch. Motion in the background works when it shows something a photo can't, like a workshop running, a film set or an event full of people. It gets in the way when it's only there to look modern.

There are a few rules we always follow. No sound: browsers won't let a video start playing on its own with sound, and even if they did, nobody wants a website talking at them uninvited. Short: five to thirty seconds that loop without a visible cut. No key messages inside it: the headline and the button belong in the page text, which is what Google and AI assistants read, not inside the video. A still image that shows while it loads, so the home page doesn't appear black. And a frozen frame for anyone who has turned on reduced motion on their computer or phone.

What you shouldn't do is use the full corporate video as a background. The voice is lost, the message is lost and the page gets much heavier. The full video goes separately, with its own play button and sound, for anyone who chooses to watch it.

Format, size and weight: adding video without slowing your site

Video is the heaviest thing a page can carry, and a slow site loses visitors before it shows them anything. A handful of decisions fixes it.

Format: MP4 with the H.264 codec, which plays on every browser and every phone. If whoever builds the site wants to fine-tune, they can add a WebM version, which is usually lighter. Size: 720p is enough for a full-screen background; 4K makes no visible difference on a home page and punishes anyone browsing on mobile data. Sound: strip it from loops, because it's weight nobody will hear. And lazy loading: the video only starts downloading when the visitor reaches that part of the page.

A real example is our page for companies. At the top, Qilimanjaro's 2025 recap plays as a loop: 32 seconds, 720p, silent and around 3 megabytes. Further down, the card for «Qilimanjaro in one minute» shows a five-second clip that weighs just over half a megabyte; the full piece, with voice-over, only loads if someone opens it. The work is on show and the page stays fast.

The final tuning is the web developer's job, but it helps if the production company delivers the versions already prepared, so nobody has to compress blindly at the end.

YouTube or hosted on your site? And what video means for Google

Both options work and they aren't mutually exclusive. Uploading to YouTube gives you free hosting, a player that works everywhere and the chance of being found inside YouTube, which is a search engine in its own right. In exchange, embedding it loads the whole player even if nobody presses play, and when it ends it may suggest other people's videos. Hosting it on your own site or on a service like Vimeo gives you more control over how it looks and what happens at the end.

What we usually recommend: silent loops always on your own site; longer pieces on YouTube and on your site too, embedded so that only an image shows first and the player loads on click.

There's a detail about Google that few people know. Since 2023 it only shows a video thumbnail in the results when the video is the main content of that page. A video at the bottom of the home page won't appear as a video. If you have an important piece, give it its own page, with a clear title, a description and the text of what's said. That text is also what AI assistants understand, which is why the video should have well-made subtitles: they let people watch without sound and make it readable.

Real cases and how we work

With Qilimanjaro, a Barcelona quantum computing company, we're their ongoing video team, and every piece is planned around where it will live. «Qilimanjaro in one minute» explains what they do and why, with voice-over, for people meeting them for the first time. SpeQtrum explains a product with motion graphics in under two minutes. The interview with Dídac, their lab manager, puts a face to the person who works in the lab. And their 2025 recap covers the year in 32 seconds. Each piece leaves the edit in several versions: the full one with sound, a loop for the website and a vertical one for social media.

That's how Bostak Films approaches corporate video: before filming, we go through your website with you and decide which page needs which video. We film in Barcelona and the Baix Llobregat, from our studio in Viladecans, and deliver each piece in the versions every placement needs, so your site can use it the same day.

If you're rebuilding your website or it feels static, book a diagnostic call and we'll tell you which video it's missing and where to put it.
