							33Recording and Playback: How to handle data recorded on P2 cards
Recording and Playback
The P2 card is a semiconductor memory card that is used as the recording medium in the professional video production and 
broadcasting devices that make up the DVCPRO P2 Series.
ySince data recorded in the DVCPRO P2 format or AVC-
Intra are in a file format, they have excellent compatibility 
with PCs. The file structure is a unique format, which in 
addition to video and audio data in MXF files contains 
various other important information items. The folder 
structure links the data as shown on the right.
Changing or deleting just one information component 
could make it impossible to recognize the data as P2 data 
or use the card in a P2 device.
yWhen transferring data from a P2 card to a PC, or when rewriting data saved on a PC to a P2 card, to prevent data loss be 
sure to use the special P2 Viewer software. Download it from the following website.
(Compatible with the Windows Vista, Windows XP and Windows 2000 operating systems.)
https://eww.pavc.panasonic.co.jp/pro-av/
yWhen using regular IT tools such as Microsoft Windows Explorer or Apple Finder to transfer data to a PC, follow the 
instructions below. However, be sure to use the P2 Viewer when returning data to a P2 card.
– Transfer the corresponding CONTENTS folder and LASTCLIP.TXT file together as a set.
Do not transfer individual files from the CONTENTS folder.
When copying, copy the LASTCLIP.TXT file at the same time as the CONTENTS folder.
– When transferring multiple P2 cards to a PC, create a folder for each P2 card to prevent clips with the same name from 
being overwritten.
– Do not delete data from the P2 card.
– When formatting a P2 card, be sure to use a P2 device or the P2 Viewer.

							34Recording and Playback: Basic Procedures This section describes the basic procedure for shooting and 
recording. Before you embark on a shoot, pre-inspect your 
system to ensure that it works properly.
* For directions on inspecting your unit, see [Inspections Before 
Shooting] (page 153).
1Insert a charged battery pack.
2Turn on the POWER switch and ensure that more than 
5 segments of the battery-remaining amount indication 
bar are illuminated.
yIf the number of illuminated segments is fewer than 5, 
first check the battery setting. If setting is not the 
problem, replace the battery with a fully charged one.
3Insert a P2 card and ensure that the P2 card access 
LED stays on in orange or green. Then, close the slide-
out door.
When more than one P2 card slot contains a P2 card, 
the card in the slot with the lowest number is used first. 
However, regardless of slot number, a P2 card inserted 
later will not be accessed until the other cards have 
been used.
Example:
If all 5 slots contain P2 cards, the cards are used in 
order of slot numbers 12345. However, if the P2 
card in slot 1 is removed and then re-inserted, the cards 
will be used in the following order: 23451.
Note that the number of the P2 card to which recording is in 
progress will be retained even when the power is turned off. 
When the power is next turned on, the last card written 
before powering-down will be the target card.

						

							35Recording and Playback: Basic Procedures
Recording and Playback
For shooting, follow the steps below.
1Select a filter according to light conditions.
2When the white balance is saved:
Position the WHITE BAL switch to [A] or [B].
When the white or black balance is not saved and 
you have no time to adjust the white balance:
Position the WHITE BAL switch to [PRST].
This adjusts the white balance against the filter 
according to the position of the FILTER control.
If the white balance is adjusted on the spot:
Position the WHITE BAL switch to [A] or [B] and shoot a 
white test subject so that it appears at the center of the 
screen. Then, follow the steps below to adjust the white 
balance.
1 Press the AUTO W/B BAL switch toward [AWB] to 
adjust the white balance.
2 Press the AUTO W/B BAL switch toward [ABB] to 
adjust the black balance.
3 Press the AUTO W/B BAL switch toward [AWB] to 
adjust the white balance again.
For directions on making adjustments, see [Adjusting 
the White Balance] (page 52) and [Adjusting the Black 
Balance] (page 55).
3Point the camera at your subject to adjust the focus, and 
zoom.
4To use the electronic shutter, set the shutter speed and 
operation mode.
For more information, see [Setting the Electronic 
Shutter] (page 56).
5Press either the REC START button or VTR button at 
the lens to start recording.
During recording, the REC lamp in the viewfinder stays 
illuminated.
6To stop recording, press either the REC START button 
or VTR button at the lens.

							36Recording and Playback: Normal Recording REC START button or VTR button at the lens starts recording of video and sound on the P2 card. A cluster of data that 
consists of video and sound generated through a shooting action, together with such added information as meta data, is 
called a “clip”.
In the unit, the camera’s recording method is selectable 
between the native recording method with the frame rate 
unchanged and the normal recording method pulling the 
frame rate down to 59.94 or 50 frames.
Images at 24P (23.98P: referred to as 24P) are pulled down 
in 2:3 mode. Images at 30P (29.97P: referred to as 30P) are 
pulled down in 2:2 mode and recorded as 59.94i (referred to 
as 60i). Images at 25P are recorded as 50i with 2:2 pulled 
down. 1080i supports 24PA (2:3:3:2 Advanced Pull down) as 
well.
AVC-Intra does not support pull-down recording.
Example of 24P Over 60i
This recording method extracts and records effective frames 
at the frame rates of the AVC-Intra recording in 1080i.
Even in native recording, the rate for outputting camera 
images and playback images is 59.94 or 50 frames that are 
pulled down.
Example of 1080/24PN (Native)

						

							37Recording and Playback: PRE RECORDING function
Recording and Playback
The internal memory of your unit is capable of storing 
several seconds of video and sound data coming from the 
camera. This capability can be used to record video and 
sound several seconds before either the REC START button 
or VTR button at the lens is pressed to start recording. To 
use this function, the menu option PRE REC MODE must be 
set to “ON”. The storage duration of the internal memory can 
be set from the menu option PRE REC TIME. PRE REC 
MODE and PRE REC TIME menu options can be found in 
the  screen on the SYSTEM SETTING 
page.The function of the menu option PRE REC MODE may be 
assigned to a desired user button by using any one of the 
menu options USER MAIN SW, USER1 SW, USER2 SW, 
MARKER SEL, or TEXT MEMO SW.
These options can be found in the  screen on 
the CAM OPERATION page.
The following is the option for PRE REC TIME.
1-8SEC (for AVC-Intra100/50 or DVCPRO HD)
Specify the duration for which data may be recorded before 
either the REC START button or VTR button at the lens is 
pressed.
