Notes on time required for recording
When recording from an HDD or DVD camcorder connected via USB cable,
the length of time required depends on the REC mode (HQ, SP, or LP) used to
shoot the video and the number of scenes the video contains. In general, videos
shot in higher image quality modes take longer to be recorded onto a disc. The
following provides a general estimate* of the time required to record a 1-hour
video containing one scene onto a disc.
When recording from an HDD camcorder
HQ mode: about 30 min (1/2 of the video playback length)
SP mode: about 20 min (1/3 of the video playback length)
LP mode: about 10 min (1/6 of the video playback length)
When recording from a DVD camcorder
HQ mode: about 60 min (almost equal to the video playback length)
SP mode: about 40 min (2/3 of the video playback length)
LP mode: about 20 min (1/3 of the video playback length)
* Depending on circumstances, the length of time required to record may be equal to or more
than the video playback length.
