What is the purpose of being able to upload .webm files in Webflow if only .mp4 files are served as background videos?

The purpose of being able to upload .webm files in Webflow, even if only .mp4 files are served as background videos, is to provide flexibility and compatibility for different browsers and devices. Let me explain further:

When it comes to using videos as background elements in a website, Webflow offers the ability to upload and use .mp4 files. This is because .mp4 is a widely supported video format that can be played on most modern web browsers and devices, making it a reliable choice for background videos.

However, there are certain cases where a video in .mp4 format might not be compatible with a specific web browser or device. This is where .webm files come into play. .webm is an alternative video format that is designed specifically for web use. It uses the VP8 or VP9 video codec, which provides high-quality compression suitable for streaming over the internet.

By allowing users to upload .webm files in Webflow, even though only .mp4 files are served as background videos, Webflow ensures compatibility with browsers and devices that may have better support for the .webm format. This allows the website to provide a smooth and consistent user experience across different platforms.

In summary, the purpose of uploading .webm files in Webflow is to offer compatibility options for browsers and devices that may have better support for the .webm format, while still serving .mp4 files as the default and widely supported choice for background videos. This flexibility helps to ensure a seamless video experience for all users, regardless of their browser and device.
