Ingesting media by using an Encode Server
Another way of pre-registering a media file is to create a placeholder clip for it; you can do this
on the Tape Ingest layout.
Note:
• The registration file for a batch recording must be in the format for clip lists, as defined by
the iTX Import Protocol. For more information about this, see "Appendix A: The iTX Import
Protocol", page 349.
Recording from a videotape
For iTX to be able to record media from a videotape, there must be a VTR connected through a
control cable to an Encode Server. The video output from the VTR may be connected directly to
the Encode Server; or, to allow the Encode Server to receive media from other sources, it may
pass through a matrix router.
In automatic and batch recordings, the Encode Server that you choose to perform the recording
controls the videotape machine. It moves the videotape to a point that is just before the point
specified for the start of recording. The difference between the two points is called the "pre-
roll" time.
It then plays the videotape from this point and starts recording after the pre-roll time. It
continues to play the videotape for the specified recording duration, or until you stop the
recording manually.
In a crash recording, you manually control a videotape machine by using playback buttons on
an ingest layout.
A VTR control button on an ingest layout enables you to switch off the ability of an Encode
Server to control a VTR. You should do this when you want the Encode Server to record media
from another source instead of the VTR. More details , page 244.
