{"success":true,"data":{"ext":"mk3d","name":"MK3D","description":"MK3D is a Matroska-based multimedia container format developed and maintained by the Matroska project. It is used primarily for storing stereoscopic 3D video, along with audio, subtitles, and chapter metadata, and is supported by various media players and editing tools. As a container format, it is generally safe to open, though malformed files or embedded streams can still affect playback software, so files from untrusted sources should be handled with normal caution.","mime":[],"risk_level":"Safe","signatures":[{"hex":"1A 45 DF A3","offset":0,"sources":[{"name":"Wikipedia","url":"https://en.wikipedia.org/wiki/List_of_file_signatures"}]}],"related":["mka","mks","mkv","webm"],"usage":{"python":"def is_mk3d(file_path: str) -> bool:\n    \"\"\"Check if file is a valid MK3D by magic bytes.\"\"\"\n    signature = bytes([0x1A, 0x45, 0xDF, 0xA3])\n    with open(file_path, \"rb\") as f:\n        return f.read(4) == signature","node":"function isMK3D(buffer: Buffer): boolean {\n  const signature = Buffer.from([0x1A, 0x45, 0xDF, 0xA3]);\n  return buffer.subarray(0, 4).equals(signature);\n}","go":"func IsMK3D(data []byte) bool {\n    signature := []byte{0x1A, 0x45, 0xDF, 0xA3}\n    if len(data) < 4 {\n        return false\n    }\n    return bytes.Equal(data[:4], signature)\n}"},"category":"Video"}}
