The first question on almost every new project is how long the video should be. We heard it before the Jewlr broadcast brief was even fully written.
Video length best practices vary by platform and content goal.
For social media (or what some now call interest media), 15–60 seconds performs best for reach and completion rates.
Branded and commercial content typically lands between 30 seconds and 2 minutes.
YouTube tutorials and educational content perform well between 7 and 15 minutes.
The consistent rule across all of these: hook the viewer in the first 3 seconds or lose them.
Length is a decision that belongs in pre-production and in the edit suite. A platform spec sheet is the last place it should start.
The executive producer owns the project at the business level. The producer owns the execution.
The EP comes in first.
Before a script.
Before a director.
Before a single crew member is hired.
Their authority covers financing, creative vision, and the decisions that determine whether a project gets made at all.
Think of them as the CEO of the production, but only for a sentence, because the analogy breaks down fast on set.
The producer runs the ground game.
They come in during pre-production and stay through delivery. Every department head reports to them. Every logistical decision runs through them.
If something goes wrong on shoot day, the producer is the first call.
Accountability is the clearest dividing line.
The EP is accountable for whether the project exists and whether it reflects the right vision.
The producer is accountable for whether it gets made on time, on budget, and to spec.
In commercial and branded production, that line is sharper than it is in film or TV. For brands hiring a production company, knowing which role handles what determines who you should actually be talking to and when.
The best practice for video length is matching duration to platform behavior and content goal. A universal number doesn't exist. Anyone telling you otherwise is selling simplicity at the cost of performance.
Here's the framework that actually holds up:
platform context sets the ceiling
content goal sets the floor
Length without those two coordinates is guesswork dressed up as strategy.
The advice most brands received three years ago was that shorter is always better. That was never fully accurate, and it's less accurate now.
Platforms have shifted from rewarding short videos to rewarding meaningful watch time. Completion rate and replays carry more algorithmic weight than raw duration.
A 90-second video that gets watched three times beats a 20-second video that gets skipped at the five-second mark.
According to Wistia's State of Video 2025 report, webinars and branded series are among the top performers for conversion. Longer content earns its length when the quality justifies every second of it.
That's not an argument for making everything longer. It's an argument for making every second intentional.
The platform breakdown is instrumental here. So is understanding what your video is actually trying to do before anyone asks how long it should be. For commercial and branded content production, that conversation starts in the brief.
The ideal video length depends entirely on which platform you're publishing to and what that platform's algorithm actually rewards right now.
Short answer: 60–90 seconds for engagement, under 30 seconds for reach.
According to Sprout Social's 2025 benchmark data, Reels in the 60–90 second range deliver the highest engagement and views. Under 30 seconds is where new audience discovery happens fastest.
Feed videos perform best under 60 seconds for completion. Stories drop off fast after 1–3 slides at 15 seconds each.
Instagram expanded Reels to 20 minutes in December 2025. Don't let that number mislead you. Reels over 3 minutes don't get distributed to new audiences. For growth-focused content, 3 minutes is still the real ceiling.
One thing worth watching: Instagram launched a TV app in late 2025. Longer content is starting to find an audience there. The distribution algorithm for TV viewing is still developing, so treat it as an emerging territory for now.
Short answer: 11–18 seconds for virality, 21–60 seconds for storytelling.
TikTok's algorithm rewards completion rate and replays above everything else. A 15-second video watched three times outperforms a 2-minute video watched once. That math doesn't change regardless of how good the longer content is.
TikTok expanded uploads to 60 minutes in 2025. Long-form only works when retention stays high the entire way through. Most TikTok audiences still aren't looking for long-form unless the topic genuinely earns it.
After 35 seconds, drop-off increases sharply. If your hook and narrative payoff weren't established in the first few seconds, you've already lost most of your audience by that point.
Short answer: 7–15 minutes for long-form, 2–3 minutes for branded content, 15–35 seconds for Shorts.
YouTube is the one platform where longer content has always had a legitimate home. The 7–15 minute range hits the sweet spot for most niches:
strong engagement
strong algorithmic distribution
enough room to build something worth watching
For branded and promotional content, 2–3 minutes is the ceiling. Beyond that you're competing for a type of attention YouTube wasn't built to sustain for brand messages.
Educational and tutorial content can run 5–15 minutes. The content type justifies the length, not the other way around.
YouTube Shorts perform best at 15–35 seconds. The platform tested 3-minute Shorts in late 2024, but the data on longer formats is still early.
Worth noting: YouTube surpassed Netflix in TV streaming in 2024. Tolerance for longer content is genuinely rising. But only when every minute is earned.
For long-form branded and documentary-style production, that bar is the starting point.
Short answer: 2 minutes for feed content, 15–30 seconds for ads.
LinkedIn's professional audience moves fast and brings skepticism as a default. If the value isn't clear in the first 5 seconds, they're gone. Length won't save a slow opener on this platform.
Two-minute videos currently deliver the highest engagement for standard feed posts. Thought leadership, interviews, and B2B content can stretch to 5 minutes for audiences willing to invest time in the right topic.
LinkedIn caps uploads at 15 minutes. Live streams can run up to 30 minutes. Ads stay tight: 15–30 seconds, no exceptions.
Short answer: 90–120 seconds for Reels, 15 seconds for retention-focused feed video.
Per Sprout Social's 2025 benchmark data, Feed Reels between 90–120 seconds generate the strongest engagement.
Standard feed videos work best at 15 seconds for pure retention, or 2–5 minutes when the goal is deeper engagement with an already-interested audience.
Facebook Live is a different animal. 30–40 minutes perform best because live audiences have already committed to the session.
Facebook's audience skews older and watches more on desktop and television compared to TikTok. That means slightly more tolerance for mid-length formats when the content warrants it.
Short answer: 20–45 seconds, regardless of account tier.
X Premium subscribers can upload up to 2 hours. Ignore that. Best performance stays under 45 seconds for feed content, no matter what your account allows.
X is not a video-first platform. Treat anything posted there as a distribution cut rather than a primary channel. Optimize for the platform it was built for first, then adapt.
Short answer: 15–30 seconds for standard Pins, 1–3 minutes for how-to content.
Pinterest audiences browse without sound at high rates. Always use text overlays. Captions carry the message when audio is off, which is most of the time.
Standard Pins perform best at 15–30 seconds. Product demonstrations and how-to content can run 1–3 minutes when the visual walkthrough genuinely needs that time.
For branded content, the length question is less about the platform and more about where the viewer is in their relationship with your brand.
A first-time viewer needs a reason to care. An existing customer will give you more time if you've earned it.
Those are two different videos, two different lengths, and two different edit decisions.
15–30 seconds for pre-roll. 30–60 seconds for broadcast and paid social.
There is no grace period on a commercial. The hook has to land in the first 3 seconds, or the rest of the budget is wasted.
Before the Jewlr broadcast brief was even fully written, the conversation was already about what those 30 seconds needed to do emotionally from the first frame. The emotional payoff first, then everything else gets built around it - the concept, the cast, etc.
Pre-roll is even less forgiving. Non-skippable ads at 15–30 seconds live or die on the opener. Skippable pre-roll has roughly 5 seconds before the skip button becomes the easier choice.
60 seconds to 3 minutes for owned and social distribution. 5–10 minutes for premium contexts.
Length in a brand film is earned by the story.
A 90-second film with a genuine emotional arc outperforms a 5-minute one built around product specs every single time.
The Entrust campaign is a good example of what this looks like in practice. Six storylines edited into one seamless flow. The pacing had to mirror the product's ease and reliability.
Every cut was a decision about trust, specifically how long it takes to build it on screen and how quickly it falls apart if the edit loses momentum.

Longer brand films in the 5–10 minute range work in specific contexts: film festival submissions, award entries, investor presentations, and owned channels with established audiences.
Ajax Originals exists specifically for that kind of work.
60–90 seconds for explainers. Under 90 seconds for homepage video.
Website visitors are making a stay-or-leave decision in real time. A long video on a homepage is a risk. Under 90 seconds keeps completion rates high and gives the page a chance to convert.
An explainer video for landing pages and product pages sits in the same range. 60–90 seconds is enough to establish a problem, present a solution, and give the viewer a reason to act.
Animated explainer formats follow the same ceiling. The medium changes, but the attention window doesn't.
For email marketing, under 60 seconds is the practical limit. Embedded video in email drives higher click-through rates than static images, but only when the ask is small.
A short teaser that drives to a landing page outperforms a long video that tries to close in the inbox.
One shoot. Multiple lengths. Plan for it before production starts.
A 60-second commercial should generate a 15-second cut for Stories, a 30-second cut for feed, and a square-format version for LinkedIn.
These are post-production decisions that need to be built into the offline edit from day one.
The Arc'teryx product education video is the clearest example of this done right. The post-production process was built to serve multiple distribution contexts from the start. That kind of intentionality in the edit suite is what makes a single shoot day produce assets with real shelf life across platforms.
Repurposing without planning produces compromised cuts. The coverage isn't there. The pacing doesn't translate. Post-production built around multi-platform delivery starts making those decisions before the camera rolls.
20% of your footage is doing 80% of the work. The editor's job is to find it and cut everything else.
It applies in two ways.
Across a content library: most of your views will come from a small number of videos. A handful of well-made pieces consistently outperform a high volume of average ones. Volume is not your strategy.
Inside the edit itself: most videos could be 20–30% shorter and be better for it. Every scene that doesn't serve the message is borrowing time from the scenes that do.
This is why video length is a post-production problem as much as a production one. The decisions made in the edit suite determine whether a video feels the right length or feels padded. No amount of good footage fixes a loose edit.
The 7-second rule refers to the critical window in which a viewer decides whether to keep watching or leave.
Drop-off is steepest in the first 7–10 seconds of any YouTube video. When viewers exit early, the algorithm registers it and reduces distribution.
The practical implication is straightforward. The first line of dialogue, the first visual choice, the first piece of music: these deserve more creative attention than almost anything else in production.
This is not a post-production fix. It truly starts in the script. It gets executed on set. Every project Ajax produces is built around the premise that the first seconds determine everything that follows.
The 10-minute rule came from a monetization threshold. Videos over 10 minutes were originally eligible for mid-roll ads, which gave creators a financial incentive to hit that length.
That threshold changed in 2020. According to YouTube's Partner Program policies, mid-roll ads are now available on videos 8 minutes or longer. The 10-minute rule as a hard standard is outdated. The actual current threshold is 8 minutes.
A few things worth knowing:
8+ minutes unlocks mid-roll ad eligibility.
10–15 minutes is where most successful monetized content lands, balancing watch time depth with retention.
Padding to hit a threshold destroys retention. A tight 6-minute video with 70% retention outperforms a padded 12-minute video with 30% retention every time. The algorithm measures how long people actually watch (not how long the video runs).
Video length affects SEO indirectly through watch time, completion rate, and audience retention. These are the signals platforms use to determine whether content is worth distributing.
Three specific connections matter:
Watch time is a primary ranking factor. Longer videos have more watch time potential, but only when retention stays high.
A 15-minute video with 30% retention produces less total watch time than a 5-minute video with 80% retention. Length without retention is not an SEO advantage.
Completion rate and replays signal quality on Instagram, TikTok, and Facebook.
Shorter content has a natural advantage here because it's easier to complete. But completion without conversion doesn't move the needle. The goal is content short enough to finish and strong enough to act on.
Shorter videos load faster and hold attention on landing pages. That directly affects bounce rate, which affects page-level SEO signals.
A homepage video that auto-plays and runs three minutes is more likely to drive exits than conversions.
One length-adjacent point worth adding here: according to research cited by Sprout Social, 69% of social media users watch videos with the sound off. Captioned content maintains retention among silent viewers. Better retention means better algorithmic distribution regardless of length.
Here's what the current data says, stripped of nuance.
| Platform / Format | Ideal Length |
| TikTok (virality) | 11–18 seconds |
| TikTok (storytelling) | 21–60 seconds |
| Instagram Reels (engagement) | 60–90 seconds |
| Instagram (reach) | Under 30 seconds |
| YouTube long-form | 7–15 minutes |
| YouTube branded content | 2–3 minutes |
| YouTube Shorts | 15–35 seconds |
| LinkedIn feed | 2 minutes |
| LinkedIn ads | 15–30 seconds |
| Facebook Reels | 90–120 seconds |
| X (Twitter) | 20–45 seconds |
| Pre-roll ads | 15–30 seconds |
| Broadcast commercials | 30–60 seconds |
| Brand films | 60 seconds to 3 minutes |
| Explainer and website video | 60–90 seconds |
| Email video | Under 60 seconds |
Universal rule: hook in the first 3 seconds (or even the first frame). Completion rate matters more than total length.
Ajax has been making length decisions on behalf of brands like Arc'teryx, Entrust, and IC Bus since 2016. The answer always starts with what the video needs to do. If that's the conversation you need to have, bring the project to Ajax Creative.
It varies by platform. Instagram Reels perform best at 60–90 seconds for engagement and under 30 seconds for reach. TikTok peaks at 11–18 seconds for virality and 21–60 seconds for storytelling. LinkedIn feed videos perform best around 2 minutes. Facebook Reels between 90–120 seconds generate the strongest engagement. X performs best under 45 seconds regardless of account type. Across all platforms, completion rate carries more algorithmic weight than total duration.
For digital pre-roll, 15–30 seconds. For broadcast and paid social, 30–60 seconds. Brand films distributed on owned and social channels typically run 60 seconds to 3 minutes. Homepage and explainer videos perform best under 90 seconds. The right length is determined by how long the story needs to land, not by what the platform allows.
Yes, but not in the way most people assume. YouTube rewards watch time and audience retention, not length alone. The 7–15 minute range performs best for most content because it generates meaningful watch time without losing viewers mid-way. Mid-roll ads are available on videos 8 minutes or longer, a threshold YouTube lowered from 10 minutes in 2020. Padding a video to hit that threshold lowers retention, which lowers distribution. A tight shorter video with high retention consistently outperforms a longer padded one.
It means 20% of your footage is doing 80% of the work. In the edit, it translates to cutting everything that doesn't serve the core message. Most videos could be shorter and stronger as a result. It also applies to content strategy: a small number of well-made videos will generate most of your views. Volume without quality rarely closes that gap.
Viewers decide almost immediately whether the content is worth their time. Drop-off is steepest in the first 7–10 seconds on every platform. A strong opening, whether that's a bold visual, a compelling first line, or an immediate value signal, is the only reliable way to hold attention past that window. On platforms where the algorithm measures early retention, losing viewers in the first 7 seconds directly reduces how widely the video gets distributed.
