Chapter 9 Managing Media Using Clips Pane
Importing media from a file or a device
Assets are imported into iVDR media storage from two sources:
File – You can import media using standard media file formats. Supported formats
include SMPTE 360M (*.gxf), or AVI DV (*.avi). Imported files can be located on a
local iVDR disk drive (fixed or removable media), or a mapped networked drive. See
also
“AVI file encoding requirements for importing” on page 307 .
Stream – The iVDR supports media transfers over the standard Ethernet port or
optional network adapters. Source devices for streaming include other iVDRs, Grass
Valley Profile XP Media Platform, or any device that supports SMPTE 360M (GXF)
streaming transfers. You must configure your network for streaming transfers prior to
using the “Import to stream” feature.
See “Setting up the Ethernet network” on
page 37 .
A transfer job is created for each “import” operation. Once created, transfer jobs are
added to the transfer job queue where they are dispatched in a first in, first out basis.
Up to four transfer jobs can execute simultaneously. Any additional jobs wait in the
queue. You can use the Transfer Monitor to check the status of your transfers.
“Guide
to using the Transfer Monitor” on page 267 .
NOTE: Before playing a clip that is being imported from a file or stream, use the
Transfer Monitor to verify that the clip transfer rate is higher than the clip data
rate. This is required to prevent playback problems due to insufficient bandwidth.

Importing media from a file
You can import media files in either SMPTE 360M (*.gxf), or AVI DV (*.avi type 1
or type 2) file format. Importing converts the files to the iVDR media file format.
Before importing an AVI file, make sure the file meets the following encode
requirements:
• Video Compression - DV (SMPTE 314) 25Mb/s
• Encoder type - type 1 (interleaved) or type 2 (non-interleaved)
• Color sampling - 4:1:1 (525 Line NTSC); 4:2:0 (625 Line PAL)
• Resolution - 720 X480 (525), or 720 X 576 (625)
• Frame Rate 29.97Hz - (525 Line), or 25Hz (625 Line)
• Audio Sampling - 16bit PCM, 48Khz sample rate, stereo
To import a file:
1. In the Clips pane, select the current bin.
For help see “Changing current bin using ‘Look in’ drop-down list.” on page 230 .
The current bin is the destination bin for the import operation.
