To perform frame-accurate
video input and output using Panasonic® variable frame rate VTR decks, you must
use the following firmware versions:
- AJ-HD3700H D5-HD deck:
SYSCON: 1.04 or later
AV: 0.21 or later
FRONT: 0.13 or later
- AJ-HD1200A DVCPRO HD deck:
SYSIF: 1.30 or later
AVDV: 1.39 or later
SERVO: 1.22 or later
Regular video input and
output is not affected by a firmware version.
NoteRefer to your Panasonic
documentation for information on verifying the firmware version.
To capture material from a Varicam device:
- Ensure your devices are properly connected
and the corresponding VTR keywords are enabled in the software initialization
configuration file. See
Configuring Software For Clip Input and Output Using a VTR.
- Open the Input Clip menu. See
Accessing the Input Clip Menu.
- From the Device Name box, select a video
device, supporting variable frame rate (for example, one of the
following options: VTR DVCProHD 720 59p or VTR DVCProHD 720 60p).
- Enter the Engineering menu and enable
Varicam (on the right side).
- Make sure the Video Input Delay is set
to zero or a positive value (negative video input delay is not supported
on Varicam capture).
- From the Timecode Mode box, select the
required timecode.
- Exit the Engineering menu and click Process.
Flame removes the
redundant frames so that the frame rate of the captured clip corresponds
to the frame rate of the project. You can monitor the process using
the VTR Status display. The Current Frame Rate field is updated
depending on the frame rate of the captured material.
NoteWhen performing operations
in Varicam mode, audio/video synchronization largely depends on
frame rate compatibility and can be guaranteed only if the following
conditions are observed: (1) Material shot at 24 fps and captured
into a 24 fps project (2) Material shot at 30 fps and captured into
a 30 fps project (3) Material shot at 60 fps and captured into a
60 fps project.
