About DM_1 files
A .dm_1 file is a replay data file primarily used by video games, including Call of Duty 4: Modern Warfare, Quake, and Painkiller, as well as legacy presentation software like InstallShield DemoShield. It stores a sequence of engine instructions, player inputs, and coordinate data rather than actual video pixels.
Users often want to convert a .dm_1 file to a standard video format like MP4 or MKV to share gameplay on platforms like YouTube. The main disadvantage of the .dm_1 format is its strict dependency on the original software. You cannot open it with standard media players like VLC. It requires the exact game and often the exact patch version that recorded it. If the game updates, old replay files will likely break and become completely useless.
Because a .dm_1 file contains proprietary engine commands instead of video data, standard online converters fail to process it. The most realistic workaround to convert this file is to load the demo within the original game engine and use screen recording software like OBS Studio to capture the output as an MP4.
This file format is exceptionally difficult to convert programmatically. Only the original software can properly read or export the 3D data.
Convert.Guru analyzes your DM_1 file, detects the exact format, and lets you read the text inside.
Users also converted DM, DM_2, DM_3 and DM_4 files.
