GFCAM Files and Folders
GFCAM video and audio media files record in MXF format.
Each GFPAK stores the video MXF files in:
(Windows) drive:\BINxxx\VIDEO
(Macintosh) Macintosh HD/BINxxx/VIDEO
Each GFPAK stores the audio MXF files in:
(Windows) drive:\BINxxx\AUDIO
(Macintosh) Macintosh HD/BINxxx/AUDIO
The GFCAM video file directory stores MXF files regulated by SMPTE 390M (MXF
OP-Atom) and SMPTE 381M (MXF mapping MPEG streams into MXF GC). If a video clip
needs to split, such as under the FAT32 file system, the system creates multiple MXF files
for that clip.
The GFCAM audio file directory stores MXF files regulated by SMPTE 382 (MXF mapping
AES3 and BWF into the MXF GC). Each file has an AES channel that consists of two audio
channels. For example, the system creates two MXF files from two AES channels (four
audio channels). If an audio clip splits, the system creates multiple audio files for that clip.
