Extract text from Havok movie files (HKM)
To convert HKM movies to another format, you need Havok SDK or other Game software.
To convert other file formats to the "Physics Engine Movie" file type, you need software like Havok SDK or a similar tool.
The .HKM file is a Havok Movie File created by the Havok physics and animation middleware. Game developers and 3D animators use this format to record real-time physics simulations, character animations, or in-game cinematic sequences. These files are highly specialized and are typically handled only by the Havok SDK or the specific video game that originally generated them.
The .HKM format is strictly proprietary, closed-source, and deeply tied to the specific version of the game engine used to create it. This is a major disadvantage for end-users because it is not a standard video file. You cannot open it with common media players like VLC or Windows Media Player. It requires a specific 3D game engine environment to render the underlying physics data into a visual output. Files can also become broken or incompatible if the game engine receives an update.
Users typically want to convert .HKM to standard video formats like MP4, AVI, or MKV so they can share gameplay or simulation footage. However, because the file contains 3D simulation coordinates rather than standard video pixel frames, direct conversion is usually impossible outside the original game engine. Standard online converters fail completely when processing .HKM files because they lack the proprietary Havok rendering engine needed to reconstruct the scene.
Often, only the original software can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your HKM file, detects the exact format, and lets you read the text inside.
If you want to convert HKM file to , you can use Havok SDK or similar software from the "Game Physics Engine Recording" category. In the File menu, look for Save As… or Export….
To convert files to HKM, try Havok SDK or another comparable tool in the "Game Physics Engine Recording" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our HKM converter.
