Short-Form vs Long-Form

One of the questions I get asked most often, usually somewhere in the middle of a planning call, is some version of: "Do we need a proper video, or just something quick for social?" It's a fair question and there's no single right answer. But there is a way of thinking about it that tends to make the decision a lot simpler. So here's how I'd look at it.

First, where is this video actually going to live?

This is the question that should come before anything else, and it shapes everything that follows.

If the video is going on Instagram Reels, TikTok, or YouTube Shorts, short-form wins every time. Those platforms were built for content that gets in, makes its point, and gets out. Anything over about 60 seconds is working against itself on those channels, no matter how good it is.

If the video is sitting on your website, going into a pitch deck, being shown at an event, or running as a longer pre-roll ad, then you've got room to breathe and a longer format starts to make sense.

A lot of campaigns actually need both, and the good news is that if you plan a shoot properly you can capture footage that works across all of it.

Short-form: when it's the right call

Short-form video, let's call it anything under 90 seconds, is brilliant for a few specific jobs.

It's great for grabbing attention quickly on social media, especially with new audiences who don't already know your brand. It works well for product highlights, quick announcements, behind-the-scenes clips, and anything where the goal is to get someone to stop scrolling and take notice.

It's also cheaper and faster to produce, which matters when you need to post consistently or test a few different angles at once.

The trade-off is that you don't have much time to build anything. Short-form can make someone aware of you. It's less good at making someone trust you.

Long-form: when it earns its keep

A longer brand film, something in the two to five minute range, does a completely different job. It's not trying to stop a scroll. It's trying to hold attention once you've already got it.

This is the format for telling a proper story. For showing how something works. For letting a real customer talk about their experience in their own words. For explaining something complex in a way that actually lands.

If you're a business where trust is a big part of the buying decision, and most businesses are, a well-made long-form video on your website can do a lot of heavy lifting. It gives people a reason to believe you before they've ever spoken to you.

The limitation is that you need a decent budget and a clear idea of what you're trying to say. A long video with no real focus is worse than no video at all.

The honest version: most brands need a mix

Here's the thing. Short-form and long-form aren't really competing with each other. They're doing different jobs at different points in the same journey.

Someone might see a short clip of yours on Instagram and think "that looks interesting." They click through to your website. They watch a two-minute video about what you actually do and who you've worked with. Now they're ready to get in touch.

The short clip got their attention. The longer video built the trust. You needed both.

The most efficient way to get both is to plan for both at the same time. Shoot the long-form video, and while you're at it capture the extra angles, the behind-the-scenes moments, and the shorter sequences you can cut down for social. One shoot, multiple outputs, a lot more value from the same day.

So what does your campaign actually need?

Ask yourself these three questions:

Where will it be seen first, and what will people do next? If it's a social ad, go short. If it's a website centrepiece, go long.

How much do people already know about you? If they're already warm leads, a longer more detailed video makes sense. If they're cold audiences, lead with something short and punchy.

What's the one thing you want them to feel or do after watching? If the answer takes more than one sentence to explain, you probably need more than 60 seconds of video.
