What is the KMPROJECT file format?
A .kmproject file is the project file used by KineMaster, a mobile video editor from KineMaster Corp. for Android and iOS. It holds the recipe for an edit: the timeline arrangement, the order and timing of layers, transitions, effects, text overlays and the settings you applied.
What it does not hold is the media. A .kmproject stores references to your video, audio and image files rather than the files themselves, which keeps it small, often just a few kilobytes to a few megabytes. Each project lives in its own folder next to the assets it points to. Because the media is external, moving or deleting a source clip leaves the project unable to load. That limitation is exactly why KineMaster 5.0 added the .kine package, which bundles the .kmproject together with every referenced file so a whole project can travel between devices.
Security & safety
RISK: LOWA .kmproject is a passive project description file with no executable content. The main practical risk is broken projects: because it only references media, deleting or moving the source clips leaves the project unable to load. Files are only meaningful inside KineMaster.
Format details
in a nutshellPrograms that open KMPROJECT files
Android1 app
KineMaster
Freemium Install KineMaster from Google Play, then open the app and select the project from the project list to load the .kmproject. For older backups, place the project folder where KineMaster expects it before launching.
KineMaster
Freemium Install KineMaster from the App Store and open the app; saved projects appear on the launch screen. Newer versions use the .kine package rather than a bare .kmproject. Technical details
deep spec| Encoding | Binary/structured proprietary container; internal layout not publicly documented |
| Container | Single project file stored inside a per-project folder alongside referenced media |
| Compression | Not documented |
| Encryption | None documented |
| Typical size | A few KB to a few MB, since only project metadata and asset references are stored, not the media |
| Structure | Holds the edit decision list for a KineMaster project: timeline layout, layer order and timing, video, audio and image references, transitions, effects, text overlays and applied settings. Actual media is stored separately and only pointed to by path reference. |
| Integrity | Not documented |
| Platforms | Android, iOS |
| Notes | Because a .kmproject stores references rather than embedded media, moving, renaming or deleting the referenced source files breaks project loading. This is the problem the later .kine package format solved by bundling the .kmproject together with all its media. |
| Media Type | Video editing project (non-linear editor) |
| Primary App | KineMaster (mobile app for Android and iOS) |
| Released | 2013 |
| Latest version | Superseded by the .kine package format in KineMaster 5.0 and later |

Frequently asked questions
How do I open a .kmproject file on my phone?
.kmproject. The file is not meant to be opened by tapping it in a file manager.Can I open a .kmproject file on a Windows PC or Mac?
.kmproject format. It only works inside the KineMaster mobile app on Android or iOS.Why won't my .kmproject load or why is media missing?
What is the difference between .kmproject and .kine?
.kmproject is the internal project file. .kine, introduced in KineMaster 5.0, is a package that wraps the .kmproject together with all its media so a whole project can be moved between devices.How do I turn a .kmproject into a video?
.mp4 video. The project file itself is not a video and cannot be played directly.How do I share a KineMaster project with someone else?
.kine file. That package includes the .kmproject and every referenced asset, so the recipient can open the complete project.
