A file with the BDMV file extension is a Blu-ray Information file, or sometimes called a Blu-ray Disc Movie Information file. They contain information about the contents of a Blu-ray disc, but they don't hold the actual multimedia files themselves. You can open BDMV files using MPC-HC, BDMV Player, and VLC. But you can't load BDMV files to Final Cut Pro (X/7/6) to edit cause Final Cut Pro (X/7/6) doesn't support BDMV files.
Generally, Final Cut Pro (X/7/6) supports Apple Animation codec, Apple Intermediate codec, Apple ProRes (all versions), AVCHD (including AVCCAM, AVCHD Lite, and NXCAM), AVC-ULTRA (including AVC-LongG, AVC-Intra Class 50/100/200/4:4:4, and AVC-Intra LT), DV (including DVCAM, DVCPRO, and DVCPRO50), DVCPRO HD, H.264, etc, among which ProRes will be the best format for Final Cut Pro (X/7/6).
Best BDMV to Final Cut Pro (X/7/6) Converter
Some common BDMV files includeindex.bdmv, MovieObject.bdmv, and sound.bdmv. Given that BDMV files are descriptive files only, you cannot convert them to Final Cut Pro (X/7/6) supported a video format. However, there are some converters available that are advertised as "BDMV converters" that work by converting the video/audio contents (like the MTS/M2TS files) of the BDMV folder to other formats, although instead of the actual .BDMV files.
Pavtube iMedia Converter for Mac is an example. It enables users to load from BDMV folder and convert the video and audio content in the BDMV folder to FCP X/6/7 supported ProRes in various different file types. You can choose proper Prores format to output according to the following standards:
If you computer is old or slow, or you just want to do some rough editing, you can select to output “Apple Prores Proxy)(*.mov)”or “Apple Prores (LT)(*.mov)”format to save more space and bandwidth. However, if your computer are powerful enough to handle multicam and high-resolution video and you are going to do many effects editing work with FCP X, you’d better choose to output “Apple Prores 422(*.mov)”or “Apple Prores 422(HQ)(*.mov)”for better performance.
