What's a DEM File? Is It Possible to Convert DEM to MP4?

If you're a gamer who likes to share your favorite moments in CS:GO or DOTA 2 with friends or followers, or someone who has received a DEM file but doesn't know how to play it outside of the game engine, you might be wondering if there is a way to convert DEM to MP4, a format that is more widely supported and easier to share.

The short answer is NO! DEM files cannot be directly converted to MP4 as they are not video files, but rather events of everything that has happened in the game. DEM stands for demo or demonstration, and it contains instructions to re-enact the match within the game engine version it was recorded with. In other words, there is no such thing as a "DEM to MP4 converter" available.

However, don't worry, as there is a workaround. The only thing that works is to capture your screen with a third-party video recorder while replaying the DEM file in the game engine. Next, we will walk you through the simple process.

How to Record and Convert a DEM Demo to MP4 Readily?
