Video File Format and Codec Basics

When it comes to videos, there are two important factors: file format and codec.

They are responsible for how a video is stored, compressed, decoded and viewed.

Let’s dive deeper into what these terms mean and how they impact your videos.

What Is a Video File Format?

A video file format is a specific way of storing and organizing video data on your computer and other digital devices.

The file format is like a blueprint that determines how the video information is structured within the file.

A format also includes details about the resolution, audio data, and other elements such as subtitles etc.

In simple words, a video format specifies how video data should be organized so that devices and software can understand and play it correctly.

Different video formats serve different purposes. Some are designed for high-quality playback, while others prioritize smaller file sizes for easier sharing online.

It’s important to choose the right format for your specific needs, whether you’re uploading videos to social media, creating YouTube content, or archiving family memories.

What Is a Codec?

The term “codec” is short for “compressor/decompressor,” which can be in the form of software or hardware.

Codecs work behind the scenes in all types of video-related tasks, whether you’re recording, editing, or saving videos.

They are responsible for encoding and decoding of video data.

For example, a codec formats and compresses your data in a specific way when you are saving a video, and when you play a video, a codec decompresses and reads video data in the backend.

A video file can be seen as a large and complex jigsaw puzzle. This puzzle contains pieces related to images, audio, video, and metadata, among others.

Video data consists of information about frames, audio, metadata, subtitles, and many other things.

Such data needs to be organized effectively so that it can be saved in a file and available to play on demand. That’s where codecs come into play.

They specialize in reducing the size of video files by cleverly compressing the data.

This compression involves techniques like merging similar data, simplifying color information, and adjusting the resolution.

As a result, the file size becomes smaller, which is important for storage and sharing online.

However, there’s an important distinction between codecs: they can be either “lossy” or “lossless” in their compression methods.

  • Lossy Codecs: These codecs achieve compression by removing some data from the video.

The encoding process of such a codec can lead to a slight to significant reduction in video quality, depending on the level of compression.

  • Lossless Codecs: On the other hand, lossless codecs preserve all the original data from the video, ensuring minimal quality loss.

However, preserving the video data comes at a cost- it makes the file size heavier.

Here are some popular video codecs in 2023:

  • 264(AVC): This is one of the most popular codecs in current times as it offers very good compression yet maintains a good quality of video. It’s often used by video streaming services and online sharing.
  • 265 (HEVC): This codec is an upgraded version of the above codec. It offers better compression and higher-quality video; however, it requires a more powerful device to run smoothly. It’s often used for 4k and 8k video content.
  • VP9: It’s an open-source codec designed by Google. It’s created especially for web videos where high compression is often useful to keep the file size low. It’s widely used on platforms like YouTube.
  • MPEG-2: This is an old codec that is still used for encoding videos for DVDs, cable TV, and broadcasting. However, with time, it is being used less and less.
  • MPEG-4: This is a versatile codec used for various purposes, such as web streaming, video conferencing, and smartphone videos.

Now that we’ve understood what is a file format and how a codec works, let’s dig deeper into some of the common video formats.

Most Common Video File Formats Used in 2023

When it comes to video formats, each comes with its own set of pros and cons.

How Do I Choose the Right Video Format?

Choosing the right video format can be quite challenging, especially when you’re new to videography.

However, the choice would depend on the purpose of your video and where you’ll share it.

Here are some things to keep in mind when choosing the right format:

Consider File Size:

Keep in mind that file size matters. Some formats, like MOV, can be quite large, while others, like MP4, are more lightweight. Choose based on your storage and bandwidth needs.

Think About Compatibility:

Consider where your video will be played. If it’s for a specific platform, check their recommended formats. For broad compatibility, choose formats like MP4.

Quality vs. File Size:

Balance quality with file size. High-quality formats like ProRes offer excellent video and audio but come with larger file sizes. Select what suits your requirements better.

Check Your Editing Software:

Ensure your video editing software supports your chosen format. Some programs work better with specific formats.

For example, ProRes videos work better with Final Cut Pro.

Think About Future-Proofing:

If you want your videos to remain accessible for years, consider open-source formats like MP4 and MKV, which are less likely to become outdated.

Below are some of the video format recommendations for specific purposes:

  • For Online Videos: MP4 and WEBM formats are ideal for online sharing. They load quickly and play smoothly on websites, social media, and platforms like YouTube.
  • For Home Videos: If you’re creating home videos and want them to last, MP4 and AVI formats strike a good balance between quality and compatibility.
  • For Windows: If you’re working with Windows-based applications, WMV is a reliable choice. It’s compatible with many Windows programs and other devices.
  • For Professional Video Editing: Professional video editors often prefer MOV and ProRes for their high quality and flexibility. They maintain top-notch video and audio in projects.
  • For Multi-Media Projects: If you’re working on projects with various audio tracks, subtitles, and high-quality video, MKV would be the right choice for you.

There’s no one-size-fits-all video format. The right one for your needs would depend on where you want to use your video and its purpose.

So, consider the above-mentioned pointers while choosing the format for your videos.

MP4 vs. MKV: Which One Should You Choose?

When choosing between MP4 and MKV, you should keep in mind that both formats have their pros and cons.

Let’s discuss some of the advantages of both.


  • Simplicity: If you want a format that works on almost any device or platform without installing extra software, MP4 is the best option for your needs.
  • Streaming-Friendly: MP4 is excellent for online streaming as well. The high compression and smaller size make it load quickly, making it ideal for YouTube and other social media sites.
  • Everyday Use: If you’re shooting videos with your smartphone or digital camera and want a format that’s easy to work with, MP4 is a solid choice.


  • Versatility: MKV can handle multiple audio tracks, subtitles, and various video streams, making it a good choice for videos with additional data.
  • High Quality: If you’re focused on maintaining the highest video and audio quality, MKV is the format for you.
  • Comprehensive: When storage space isn’t a concern, and you want all the features, such as multiple languages and high-quality video, MKV would be the right format for you.

If you want an easy-to-work-with and widely compatible format for everyday use and online sharing, go with MP4.

However, if you work on videos with multi-audio tracks, other media files, and the extra features, MKV is the right choice.

The choice ultimately depends on your project’s demands and where you plan to showcase your videos.

High Resolution vs Low Resolution: What’s the Difference?

A high-resolution file has a huge amount of image & video data which makes it more realistic.

It allows for better video editing as well as renders at a high quality when being played.

However, the size of a high-resolution video file is much larger than the lower resolution file.

On the other hand, a low-resolution image or video is one that doesn’t have complete image data and renders dull and lacking sharpness.

Low-resolution files are very easy to share as they are smaller in size compared to high-resolution files.

Which Video File Formats are Supported on Social Media?

When it comes to sharing videos on social media, it’s important to know which video file formats are supported.

Different platforms have their preferences, and using the right format ensures your videos display correctly.

Here’s a handy list of the video file formats supported by some popular social media platforms:
