international standards used for coding audio/video
information into digital format. Currently, MPEG-2 is
the standard for digital video formats and MP3 for
strictly digital audio formats.
non-realtime
capture
Non-realtime capture continues processing video
after the video capture playback stops in order to
ensure that no frames are dropped. Capturing video
at a higher speed reduces processing time, but yields
video of a lower quality. Capturing better quality
video requires more CPU power and more time to
complete.
NTSC
(National Television Systems Committee) A standard
format adopted by the FCC for television broadcasts
in the United States, Japan, Canada, and Mexico.
NTSC offers 525 lines of resolution per frame at 30
fps.
PAL
(Phase Alteration Line) The standard format for
television broadcasts in Germany, Great Britain,
South America, Australia, and most of Western
European and Asian countries. PAL offers 25 frames
per second.
realtime
capture
Realtime capture completes capturing during
playback of the original video. Realtime capture
requires high processing speeds and risks dropped
frames.

video, audio, photo, and settings parts.

contained within albums.
