Why the Right Video Format Decides Your Reach
The best video formats for social media are the ones each platform actually rewards: vertical 9:16 for short form feeds, square or 4:5 for mixed feeds, and 16:9 for YouTube and website embeds. Get the container right and your content loads cleanly, fills the screen, and keeps people watching.
At Apex Video Promotions, we produce promotional video for businesses every week, and the same problem comes up again and again. A strong concept gets buried because it was exported at the wrong size or ratio. The platform crops it, adds black bars, or compresses it into mush.
Below, we break down the sizes, ratios, codecs and lengths that matter, plus how to match each format to the platform it lives on. Get these right and your creative work finally gets the audience it deserves.
Social Media Video Sizes: The Numbers That Matter
The core sizes are simpler than most guides suggest. Vertical video at 1080 x 1920 pixels covers TikTok, Reels and Shorts. Landscape at 1920 x 1080 covers YouTube and website embeds. Square at 1080 x 1080 still works for mixed feeds and carousels.
Shoot and edit at the highest resolution your workflow allows, then downscale on export. Upscaling never recovers detail you did not capture.
Platform by Platform Dimensions
- TikTok: 1080 x 1920, 9:16
- Instagram Reels and Stories: 1080 x 1920, 9:16
- Instagram feed: 1080 x 1350, 4:5
- YouTube: 1920 x 1080, 16:9
- LinkedIn feed: 1080 x 1080 square or 1920 x 1080 landscape
- Facebook feed: 1080 x 1080 square or 1080 x 1350, 4:5
Sprout Social's social media video specs guide is a useful reference point for checking current requirements across platforms, since the details shift as each network updates its player.
Social Media Video Aspect Ratios Explained
Aspect ratio is the relationship between width and height, written as two numbers. It decides whether your video fills a phone screen or sits in a letterbox with wasted space.
The three ratios that matter are 9:16 vertical, 1:1 square and 16:9 landscape. A 4:5 ratio sits between square and vertical and suits feed placements where you want more height without going full screen.
Here is the rule we work to: pick the ratio the platform's main feed uses, not the ratio that flatters your footage. A wide shot of a shop floor looks impressive at 16:9 and becomes a thin strip on a phone. Reframe the concept for vertical first, then adapt outward.
Video Formats and Codecs for Social Media: What to Export
Export as MP4 with H.264 video and AAC audio for almost every social platform. This combination balances compatibility and quality, and it is the format most platforms accept without a re-encode that damages the picture.
Pixflow's creator reference on formats and codecs recommends MP4 with H.264 for YouTube uploads, while noting the platform accepts other formats. In practice, MP4 covers you everywhere.
MOV is fine for editing masters and Apple workflows, but it creates larger files and offers no advantage once you upload. Keep MOV as your archive format and MP4 as your delivery format.
MP4 or MOV? Frame Rates and Bitrates
For most social content, export at 25 to 30 frames per second. Shootlab's guidance on social video export settings suggests 25 to 30 fps, H.264 encoding and a bitrate of around 10 to 20 Mbps, plus turning off HDR where possible.
That last point matters. HDR footage can look washed out or overly contrasty after a platform's own processing. Exporting in standard dynamic range gives you a predictable result.
Social Media Video Length: How Long Should Each Clip Be?
Length should follow the platform's viewing habit, not your script. Short form feeds reward clips of roughly 15 to 60 seconds. YouTube suits longer pieces of several minutes. Website hero videos work best under 60 seconds, where the goal is a quick impression rather than a full story.
The practical test is simple. If the first three seconds do not give someone a reason to keep watching, the length is irrelevant. Front load the hook, then earn the extra seconds.
| Format | Typical Length | Best Use |
|---|---|---|
| Vertical short form | 15 to 60 seconds | TikTok, Reels, Shorts |
| Square feed video | 30 to 90 seconds | LinkedIn, Facebook |
| Landscape YouTube | 2 to 10 minutes | Explainers, reviews |
| Website hero video | 30 to 60 seconds | Homepage, landing pages |
Matching the Format to the Platform
Platform choice should drive the format, not the other way round. Engage Coders' comparison of social platforms for business video draws a clear line between long form video on YouTube and short form on TikTok and Instagram Reels. That split is the starting point for any plan.
Vertical 9:16 at 1080 x 1920 is the default for TikTok, Reels and Shorts, as InfluenceFlow's 2026 specifications guide sets out. For Instagram specifically, Reels, Stories, Live and in feed posts each behave differently, and Raw Pictures' breakdown of Instagram video types is worth reading before you plan a single shoot.
If you sell products, shoppable and interactive video ideas are worth testing. EmbedSocial's roundup of social video ideas covers several formats beyond the standard promotional clip.
This is where most plans fall over. Teams produce one landscape master and crop it everywhere. The result is a vertical video with the subject's head cut off and captions running off screen. Build a vertical master first.
Producing Correctly Formatted Video Without a Film Crew
You do not need a crew to hit these specifications, but you do need someone who understands them. The common mistake is treating format as an afterthought, bolting a vertical crop onto a landscape edit days before launch.
A cleaner route is to brief the format up front. Decide the platforms, set the ratios, and build the concept around the vertical frame first. Everything else adapts from there.
This is the workflow we use at Apex Video Promotions. We take a brief, existing website or product information and turn it into promotional video built for the platforms it will run on, with the correct ratios and export settings baked in from the start. Concepts are typically delivered within 24 hours, there is no cost until you approve the concept, and turnaround is around two weeks. No filming days, no camera crews, no production schedules to manage.
For businesses weighing this against a traditional shoot, our guide to savings versus traditional video production sets out where the time and cost actually go.
Conclusion
Getting the format right is the difference between a video that gets watched and one that gets scrolled past, and the specifications are not complicated once you know them. The harder part is producing consistently to those specifications without a crew, a studio and weeks of scheduling.
That is exactly what we built Apex Video Promotions to solve. We combine AI-powered production with human creative direction, deliver a concept within 24 hours at no cost until you approve it, and turn around finished promotional video in around two weeks. Every export is built for the platform it runs on, from vertical short form to website hero video.

Frequently Asked Questions
What is the best video format for social media?
MP4 with H.264 video and AAC audio is the most widely compatible choice across platforms, and it is the format recommended for YouTube uploads in particular. It balances file size and quality well enough for most organic and paid content. Export at 1080p as a baseline, keep the bitrate moderate at around 10 to 20 Mbps for most social clips, and turn off HDR where possible to avoid washed out colours after upload. Always check the specific platform's current specification before a major campaign.
What aspect ratio should social media videos use?
Vertical 9:16 at 1080 x 1920 pixels suits TikTok, Instagram Reels and YouTube Shorts, and it is the format most short form platforms now favour. Square 1:1 still works for feed posts on some platforms, while 16:9 remains the standard for YouTube long form and LinkedIn. If you only have budget for one master file, shoot or generate in 9:16 first, then crop to 1:1 and 16:9 for other placements. Cropping from a wider master is harder than reframing down.
Should social media videos be MP4 or MOV?
MP4 is the safer default because it is accepted almost everywhere and produces smaller files for the same quality. MOV is fine for editing and archiving, particularly on Apple hardware, but some platforms re-encode it less efficiently. For delivery to a platform, export MP4 with H.264 video and AAC audio. Keep your MOV masters for future edits. The codec matters more than the container, so confirm the platform accepts your chosen combination before uploading a large batch.
How long should a social media video be?
Short form placements on TikTok, Reels and Shorts work best between 15 and 60 seconds, with the strongest hook in the first three seconds. Feed videos on Instagram and Facebook often perform between 30 seconds and two minutes. YouTube long form rewards eight minutes or more when the content justifies it, and LinkedIn tolerates one to three minutes for thought leadership. Match length to the platform's behaviour, then cut ruthlessly. A tight 30 second clip usually beats a padded 90 second one.
How do I resize one video for every platform?
Generate or shoot a vertical 9:16 master at 1080 x 1920, then create crops for 1:1 and 16:9 rather than stretching the frame. Keep key text and faces inside a central safe zone so nothing important is lost when cropping. Export each version as MP4 with H.264 and check it on a phone before publishing. If you are producing promotional video at volume, an AI powered workflow can output several aspect ratios from one brief, which saves re-editing the same clip for each platform.
