Spanned clips are clips that extend from one card to another. Avid supports working with
spanned Canon XF clips in your Avid editing application. For more information about spanned
clips, see “Spanned Clips” on page 392.
Using the GFCAM AMA Plug-In
The Ikegami GFCAM HDS-V10 is a tapeless camera/recorder that uses flash memory instead of
video tapes as a recording medium. GFCAM devices record MPEG-2 Long GOPmedia onto a
GFPAK
™
, a removable high-speed storage medium. GFCAM is only available through the AMA
method. 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.
GFCAM allows gapless recording over several GFPAKs, however, each GFPAK handles the
contents as a separate clip. If you record across three GFPAKs, you create three separate clips.
You can then edit those clips together into one continuous sequence.
