What are the advantages of flash memory?
Your videos and photos are recorded in the built-in memory (GJII!) only) or
on commercially available SD/SDHC memory cards
2
using AVCHD
specifications
3 .
Recording on flash memory means that there are no moving
parts in the recorder unit of the camcorder. To you, it means a camcorder
that is smaller, lighter and faster. In fact, using the Quick Start function
(OJ
48) you can open the LCD panel and start recording within
approximately one second.
Any New Functions?
Pre-recording
When pre-recording
(OJ
68) is activated, the camcorder
starts recording video continuously into a temporary 3-second memory.
When you press the
[START/STOP]
button, the scene recorded will have
started 3 seconds before you started shooting. This is especially useful
when it is difficult to predict when to start recording.
Face Detection
With face detection (CD 72), have the camcorder
automatically detect people's faces and use this information to adjust the
focus and set the best exposure for beautiful videos and photos.
Video Snapshot
Discover a new fun way to shoot video with video
snapshot scenes
(OJ
66). Shoot short (approx. 4-second) scenes and
arrange them into a video clip set to your favorite background music.
I
Cinema Mode
Give your recordings a cinematic look by using the
[ltJ
Cine Mode] recording program
(OJ
65) with the 24 fps progressive
frame rate.
