							32Recording and Playback: How to handle data recorded on P2 cards 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.

							33Recording and Playback: Basic Procedures
Recording and Playback
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 148).
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.

						

							34Recording and Playback: Basic Procedures 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:

							35Recording and Playback: Normal Recording
Recording and Playback
REC START/STOP 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 or 59.94P 
(referred to as 60i and 60P). Images at 25P are recorded as 
50i or 50P 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
Example of 720P 24P Over 60PThis recording method extracts and records effective frames 
at the frame rates of the AVC-Intra recording in 1080i, and 
DVCPRO HD and AVC-Intra recording in 720P.
For 720P, it is possible to record images where the length is 
2 to 2.5 times longer than the pull-down recording.
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)
Example of 720-24PN (Native)

						

							36Recording and Playback: PRE RECORDING function 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/STOP 
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/STOP button or VTR button at the 
lens is pressed.

						

							37Recording and Playback: Variable Frame Rate (VFR) Recording Function
Recording and Playback
This unit can shoot at a lower frame rate (undercrank) or 
higher frame rate (overcrank) in the 720P mode. The native 
(PN) recording mode or standard (OVER) recording can be 
selected.
1Open the  screen from the SYSTEM 
SETTING page using the menu.
Set SYSTEM MODE to “720-59.94P (60P/50P)”, REC 
FORMAT to “AVC-I 100/24PN”, and VFR to “ON”.

back is normal (1
						

							39Recording and Playback: Variable Frame Rate (VFR) Recording Function
Recording and Playback
This way of shooting provides the quick motion effects used, for instance to realize speeding clouds, a person standing 
stationary in the blur of a moving crowd, and kung-fu moves. For example, when the scenes have been shot using the 24P 
recording format for specifying playback frames, the speed of the quick motion effects can be doubled by setting the VFR 
recording frame rate to 12 fps.
yWhen REC FORMAT is set to “DVCPROHD/60P” or “DVCPROHD/50P”, the quick motion effects can be obtained by using 
a nonlinear editing system to process what has been recorded.
This way of shooting provides slow motion effects used in car chases, action scenes, climactic scenes and other dramatic 
moments. For example, when scenes have been shot using the 30P recording format for specifying the playback frames, the 
speed of the slow motion effects can be halved by setting the recording frame rate to 60 fps. Images in the 720P progressive 
format will create smooth slow motion sequences with a high picture quality.
yWhen REC FORMAT is set to “DVCPROHD/60P” or “DVCPROHD/50P”, the slow motion effect can be obtained by using a 
nonlinear editing system to process what has been recorded.

							40Recording and Playback: Loop Recording This way of shooting provides a flow effect and may, for instance, be used to shoot a subject on a far side of a road with a 
stream of fast-moving cars as the flow, in such a way that the stationary subject comes into focus though the cars.
When two or more P2 card slots contain cards, this function 
allows the target P2 card to be switched in order. Even when 
the free space of a P2 card is used up, this function 
continues recording while erasing existing data.To use this function, the menu option LOOP REC MODE 
must be set to “ON”. The option LOOP REC MODE can be 
found in the  screen on the SYSTEM 
SETTING page.
