Set Index Picture
In some cases the first frame and last frame index pictures may not clearly represent the content of a clip,
i.e. in a pan the most telling images may only appear towards the end of the pan. Click Set Index Picture
to select another frame, which will serve as the Picon of the clip. See also “Views” on page 238.
Set Marker
You can set markers at any position and attach comments to them. Also see “Setting Markers and Adding
Comments” on page 271.
When a live source is used, the marker button is not available.
A/V Inputs (Selecting Source Tracks, H)
The A/V signals (Source Tracks) to be digitized are determined by a series of buttons to the right of the
inlay. Click the appropriate buttons to select (icon highlighted) or deselect them.
Source Track selection affects Media File generation. See also “Media Management” on page 313.
For example, activate the Video Source Track and Audio Source Tracks A1 to A4. The system then creates
five different Media Files, one for each signal.
However, this occurs only when digitizing.
DV: Channels 3 and 4
Some DV camcorders can record and play four audio channels, although at a reduced sampling quality of
32 kHz. When captured, this audio is converted to system-compatible 48 kHz. However, in DV embed-
ded, only two
channels (@ 48 kHz) can be output.
Avid Liquid
It is possible to later add Source Tracks to clips and to re-capture these clips with all active Tr ac k s . Add
Tra c k s by clicking the appropriate checkboxes in the clip’s Properties.
The number of Audio Source Tracks available depends on the system configuration and the current audio
input.
If V is not selected, the video signal will not be displayed in the inlay.
Note that even if you want to capture DV audio only, there must be a video signal present (to ensure cor
-
rect synchronization).
