What is the KINE file format?
A .kine file is a project export from KineMaster, the mobile-first video editing app made by KineMaster Corporation. It is not a finished video. Instead it holds everything needed to keep editing: the project's internal .kmproject descriptor plus copies of every clip, image, audio track, and font the edit relies on. Under the hood a .kine is a .zip archive, so the whole project travels as one portable file.
KineMaster added .kine export in version 5, released in 2019. Before that, projects lived only inside the app on a single device. The .kmproject file records the timeline, layers, clip order, transitions, effects, color adjustments, text styling, and audio, while the bundled media supplies the actual source footage. That combination is what lets a project reopen intact on another phone, tablet, or computer.
Security & safety
RISK: LOWA .kine is a project archive, not an executable, so opening one in KineMaster carries little inherent risk. Because it is a ZIP container, treat files from unknown senders with normal caution and scan them, since any bundled media could in theory be malformed. The file itself does not run code.

deep spec| Encoding | Binary |
| Container | ZIP archive |
| Compression | DEFLATE (standard ZIP compression); embedded media is usually stored without recompression |
| Byte order | N/A (ZIP container) |
| Structure | A .kine file is a ZIP archive bundling a project's .kmproject descriptor file together with every media asset the project references (video clips, images, audio, fonts). The .kmproject file records the timeline, layers, clip order, transitions, effects, color adjustments, text and styling, and audio tracks, while the bundled media provides the actual source content so the project opens intact on another device. |
| Integrity | Per-entry CRC-32 checksums provided by the ZIP container format |
| Typical size | A few megabytes to several gigabytes, depending on the number and length of the bundled media clips |
| Platforms | Android, iOS, Windows, macOS, ChromeOS |
| Notes | Exporting to .kine packages the whole project as a single portable file, unlike the internal .kmproject file which references media by path and does not travel with it. Importing a .kine on a new device restores the full editable project. The Merge Project tool lets an imported .kine be combined with an existing project or with other imported .kine files. |
