Multiple Slots 
AJ-HPX3000 is equipped with five slots for P2 cards. Up
to five cards may be inserted in these slots for
continuous recording. They also provide new recording
capabilities specific to memory cards.   
Hot-Swap recording
The Hot-Swap capability allows cards not in use to
be replaced without interrupting recording. This
facilitates continuous recording.
LOOP REC
AJ-HPX3000 can retain a certain amount of
previously recorded material by continuously loop-
recording data into a specified recording area.
INTERVAL REC/ONE SHOT REC
The 
AJ-HPX3000 features interval recording at
minimum one-frame intervals. This function is
particularly suited to shooting science and nature
programs. Frame-by-frame shooting is simple with the
one-shot recording function.
PRE-RECORDING function
In standby status, AJ-HPX3000 always stores video
and sound input to the camera for up to 8 seconds.
This means that the PRE-RECORDING function,
when turned on, records the video and sound for a
preceding duration preset by the user.   This feature
recovers critical moments that you might have
missed.
Proxy recording (when AJ-YAX800G attached)
By installing the optional video encoder card (AJ-
YAX800G), MPEG4 format video and real-time
metadata such as time code data can be recorded
simultaneously on the P2 card and the SD memory
card, together with the video and sound recorded by
the camera. This function is useful for confirmation
of editing of clips. For more information about the
approximate duration for proxy recording, see
[Approximate Proxy Recording Time (optional) on
SD memory cards] (page 11).
 Please also see
<Cautions in using SD memory cards>. (page 22)
Data protection
Data on P2 cards will not be lost due to overwriting
unless the files are deleted or the cards are
initialised. Recordings are written only to free space.
HD: Format AVC-I100/AVC-I50/DVCPRO HD
SD: Format DVCPRO50
Recorded video is compressed through a component
digital recording method that uses a state-of-the-art
compression technology, and sound is recorded using
the non-compression PCM recording method, which
excels in such areas as S/N ratio, frequency bands,
waveform properties and reproducibility of fine areas.
These methods further enhance the quality of images
and sound. 
And it is also possible to select AVC (Advance Video
Coding) compression of the ISO/IEC14496-10 standard
in addition to DVCPRO HD in HD mode. The unit
performs the in-frame compression.
It is also possible to select DVCPRO HD in addition to
H.264/AVC Intra Profile compression in HD mode. The
unit performs the in-frame compression.

Note
When the clip is played back in the format not selected
on the menu, the picture may be disturbed until the
format is detected.
4-channel Digital Audio Recording (all formats)
In HD (1080i) mode, 4-channel digital audio recording is
used. 
All formats in SD mode also support 4-channel digital
audio recording with high-quality sound (48 kHz/16 bits). 
Clip Thumbnailing
Automatic generation of thumbnails
AJ-HPX3000 automatically generates a thumbnail for
each recording cut (clip). It is possible to make use of
this on the camera-recorder as well as for non-linear
editing purposes, and after uploading to a server.
Thumbnail display on the LCD monitor
The 3.5-inch color LCD side of the your video
camera recorder can provide a multi-screen view
of 12 clip thumbnails. You can choose a desired clip
to playback instantly.
Seamless playback of selected clips
You can select more than one clip from the
thumbnail view for continuous playback and output
of seamless video. 
‹
Note
During continuous playback of clips in different
recording formats, seamless playback is not available.
Display of clip information
By selecting clips, information added to clips, such
as the recording time, Text Memo, Shot Marks and
metadata can be checked.
