Video file (H.264) ➀
The HD-quality (1920x1080 30p, 1280x720 60p, or 1280x720
30p) videos have an HDV_####.MP4 format.
The SD-quality videos have an SDV_####.MP4 format.
The file number automatically increases when a new video file is
created.
Up to 9,999 files can be stored in one folder. A new folder is
created when more than 9,999 files have been created.
Photo file ➁
As with video files, the file number automatically increases when
a new photo file is created.
The maximum file number allowed is the same as with video
files. The photos have an SAM_####.JPG format.
The folder names increase in this order: 100PHOTO
101PHOTO etc.

When the 9,999th file is created in the 999th folder (i.e. HDV_9999.MP4 is created in the 999th
VIDEO folder), no more folders can be created. Backup your files to a PC and format the storage
media, then reset the file numbering from the menu.
The name of a video file recorded by the camcorder should not be modified, since proper playback
by the camcorder requires the original folder and file naming convention. •
