What is BDM file?

BDM files contain information about a disc and it is associated with a video recording in the AVCHD format (Advanced Video Coding High Definition), usually created by cameras registering high resolution image. It is worth mentioning, that a BDM file does not contain any audio data, but only data describing content of records located in a specific folder.

Additional information

  1. BDM files are stored in the AVCHD/BDMV folder on the data carrier, and are usually named index.bdm or movieobj.bdm . Files with the BDM extension are not generated on optical drives, but only on hard drives, memory cards or flash memory devices.
  2. An equivalent of BDM files, also utilised on Blu-Ray optical discs, are the BMDV files. Similarly like BDM files, they do not store video data, but the information about content of files located in a specific directory on a disc, therefore, it is not possible to convert them into any other popular video format.
  3. BDM files usually contain text data, therefore, in order to display its content, user may change its extension into TXT and open it, for instance with Windows Notepad.
