The essentials
- Dominant format: vertical 9:16, subtitled, with a hook in the first two seconds; short video remains the most widely distributed format on Instagram, TikTok, Facebook and YouTube.
- 2026 lengths: 15 to 45 seconds for Reels and Shorts, 30 to 90 seconds on LinkedIn, 1 to 3 minutes on TikTok for instructional content.
- Retention benchmarks: aim for more than 50% of viewers still there at 3 seconds and 25 to 35% full views on a 30-second video.
- Production: a smartphone, a €30 lapel microphone and editing in CapCut or Adobe Express are enough; consistency counts for more than cinema quality.
Video has become the default format for organic distribution: in 2026, Reels, Shorts, TikTok and LinkedIn videos get 30 to 100% more reach per post than still images on the same accounts. That advantage disappears if the video is badly framed, has no subtitles or is too long for its network. Here are the practices that make the difference, with up-to-date specifications and the metrics to track.
Formats and lengths network by network
| Network and format | Ratio | Recommended length | Technical maximum | Specific feature |
|---|---|---|---|---|
| Instagram Reels | 9:16 | 15 to 45 s | 3 min | Cover visible in the grid; on-screen text kept out of the interface zones |
| TikTok | 9:16 | 20 to 60 s, 1 to 3 min for instructional content | 10 min (60 min on upload) | Internal search: keywords in the description and spoken aloud |
| YouTube Shorts | 9:16 | 30 to 60 s | 3 min | Video title indexed; can point to a long video |
| YouTube long video | 16:9 | 6 to 12 min | 12 h | Chapters, custom thumbnail, detailed description |
| 9:16 or 1:1 | 30 to 90 s | 15 min | Dedicated video tab in the app; subtitles essential (muted playback) | |
| Facebook Reels | 9:16 | 15 to 60 s | 90 s | Distributed beyond followers too; older audience |
| X | 16:9 or 1:1 | 20 to 60 s | 2 min 20 (more with Premium) | Autoplay without sound |
These lengths are comfort zones, not absolute rules: a two-minute video that holds attention does better than a 20-second video abandoned at the third second. The right metric is retention, not length.
The structure of a video that holds attention
Platforms decide in the first few seconds whether to keep distributing. A proven structure:
- 0 to 2 seconds, the hook: one sentence that states a problem or a concrete promise (“Here is the mistake that costs 20% of your reach”), a moving visual, no logo and no title sequence.
- 2 to 5 seconds, the context: who is speaking and why they are credible, in one sentence.
- The body: a single message, split into two or three points, with a change of shot or of text every 3 to 5 seconds.
- The ending: a clear conclusion and a single call to action (comment, save, link in bio). Avoid the “thanks for watching” that prompts people to drop off before the end.
Subtitles are not optional: most mobile viewing happens without sound, particularly on LinkedIn and Facebook. Editing tools generate automatic subtitles that need proofreading (proper nouns, figures). Place the text in the centre of the frame, away from the areas covered by the interface (bottom and right-hand side on TikTok and Reels).
Producing without a studio: kit and tools
The level of production expected organically is that of a smartphone used well. The basic kit costs less than €150: a wireless lapel microphone (sound makes more difference than image), a small tripod, a light source facing the subject. On the software side:
| Tool | Use | Indicative 2026 price |
|---|---|---|
| CapCut | Mobile and desktop editing, automatic subtitles, templates | Free; Pro around €10 / month |
| Adobe Express | Simple editing, brand-coloured styling, format variants | Free; Premium around €12 / month |
| Canva | Template-based videos, text animation, multi-format export | Free; Pro around €110 / year |
| Descript | Editing through the text, silence removal, transcription | €15 to €30 / month |
| DaVinci Resolve | Advanced editing, colour grading | Free |
To keep up the rhythm, shoot in sessions: half a day a month is enough to record 8 to 12 short videos from a list of customer questions. The editing is then done in series, with a reusable subtitle and styling template. The choice of creative tools is detailed in visual creation tools.
Adapting one video to several networks
Posting the same video everywhere works provided you adapt it. Remove the TikTok watermark before publishing on Reels (Instagram reduces the distribution of videos carrying a competitor's logo). Rewrite the description for each network: searched keywords on TikTok and YouTube, a more professional tone and an open question on LinkedIn. On YouTube, one long video can supply three to five Shorts. The differences in tone are covered in adapting your tone to each network. The through line remains the calendar: video fits into the editorial calendar with a target share, in 2026, of 40 to 60% of posts on Instagram and TikTok, and 25 to 40% on LinkedIn.
Measuring: the metrics specific to video
- 3-second retention rate: the share of viewers still there after the hook; below 50%, rework the first two seconds.
- Average watch time: expressed as a percentage of the video; 25 to 35% full views is a good level for 30 seconds, 40% and above is excellent.
- Rewatches and shares: the heaviest signals in distribution on TikTok and Reels.
- Views from non-followers: measures the video's ability to travel beyond your audience; 60 to 90% is common on TikTok, 30 to 60% on Reels.
- Clicks and conversions: to be tracked on the site side with tagged links and the social conversions in GA4.
Compare these metrics video by video, by hook and by theme, rather than account by account: that is how you build a list of the hooks that work for your audience.

Frequently asked questions
Should you favour short video or long video in 2026?
Short vertical video remains the most widely distributed organic format and the best entry point for reaching new people. Long video, especially on YouTube, builds trust and turns up in searches. The right mix for an SME: short videos every week, one long video a month if the subject justifies it.
What is the ideal length for a Reel or a TikTok?
Between 15 and 45 seconds for a Reel, between 20 seconds and a minute for a TikTok, with tolerance up to three minutes for tutorials that hold attention. The decisive criterion is not length but retention: a video watched more than 30% of the way through will be distributed whatever its length.
Can you repost the same video on several networks?
Yes, provided you remove the watermarks, adapt the format (9:16 everywhere except long-form YouTube and X), rewrite the description for each network and stagger publication by a few hours. Instagram reduces the reach of videos carrying a visible TikTok logo.
How do you get reliable subtitles quickly?
CapCut, Adobe Express, Descript and the native functions of Instagram and TikTok generate automatic subtitles in a few seconds. Always proofread the figures, proper nouns and industry terms, then settle on an identical font and position for all your videos to create a visual signature.
