What’s the best video format?

Video is everywhere. We just can’t seem to get enough of it. But making a video isn’t the same as writing a blog post. There's more tech involved. For starters, you have to know a thing or two about video file formats.

Video is everywhere. We just can’t get enough of it. 

These stats (and all the others) make a pretty compelling case for adding video to your marketing, recruiting, and internal comms strategy.

But making a video isn’t the same as writing a blog post. There’s more tech involved. You have to create, edit, and package your video in a way that works across different platforms. (The only thing worse than not using video is using video with poor playback quality.) 

In this article, we take a look at a crucial part of the video creation process: choosing the right video file format. 

This can get pretty technical, so to avoid getting bogged down, we’re just going to scratch the surface and focus on formats that work well for videos designed to be streamed online on platforms like YouTube, Instagram, TikTok, Twitter, and Facebook.

What is video format?

Heads up: we’re about to get technical for a minute. If you just need a quick-and-dirty list of the best video file formats for each platform, feel free to skip ahead. But for those of you who geek out on this stuff, here’s a high-level overview of what video file formats entail and why choosing the right one matters. 

Video format is made up of two parts: a container and a codec. Different containers work only with specific codecs and vice versa. 

The container comprises the “meat” of the file. In a nutshell, it holds together your video, audio, and metadata. Most people will recognize containers by their file extension names, such as .mp4, .mov, and .avi

The codec is software that compresses and decompresses the video. It affects the final file size and video/audio quality. The current standard for video streaming is H.264.

Each video file format (and there are a lot of them) is optimized for a specific use. That’s why certain formats like MOV or MP4 are perfect for videos on the web, while others work really well for Blu-Ray videos or movies projected on a cinema screen.

Bitrate and video file formatting

If we’re on the subject of video file formats, we need to talk about one other number: the humble bitrate.

What is bitrate? One bit is the smallest unit of computer data. The bitrate is the number of bits displayed over a unit of time. In online streaming, we usually measure by millions of bits per second, so “1 mbps” is one million bits per second. 

As a rule of thumb, the higher the bitrate, the higher the quality of the video. But for the purposes of online streaming, you don’t want to format your video with the highest bitrate. 

Your goal is to create something that streams immediately but still looks great — this means balancing compression and bitrate against watchability. When choosing a video format for online streaming, you need to pick something that works for your needs with a bitrate that doesn’t break the internet.

Choosing the best video format by platform

So what’s the best video file format for online streaming? That depends on where you’ll post your video and how your audience will watch it. Here’s a quick list of the video file formats supported by the major social media and streaming platforms.
