Preparing Custom BWF Information
Additional information can be displayed in bin columns, but this information needs to be coded in a particular format. The recording device must provide this information in the BWF Description field, using the following keyword/value pairs:
uKEYWORD=data[CR/LF]
u | Letter code of the manufacturer. Use the letter u unless otherwise instructed by Avid. |
KEYWORD | Designation of the bin column. |
= | Terminates the keyword. |
data | Information to include in the bin column. |
[CR/LF] | (carriage return/line feed) Terminates the data. |
For example,
uSCENE=1A[CR/LF]
After importing, this keyword/value pair displays "1A" in the Scene column of the bin into which it was imported.
The following table describes how to code BWF information for particular bin columns:
Comments (editable text field that appears in the bin script view) | uNOTE=x, where x is text. |
Scene | uSCENE=x, where x is text. |
Take | uTAKE=x, where x is text. |
Tape Name | uTAPE=x, where x is text. If there is no tape name specified, a name is created by concatenating the origination date and the file name. |
TRK1 through TRK8 | uTRKn=x where n is the track number, and x is text. |
User Bits (custom column) | uUBITS=$hhhhhhhh where hhhhhhhh is the 32-bit hexadecimal encoded user bits. |
In addition, to assign a file to a particular track number, the file name needs to end in _n, -n, or a space followed by n (where n is the track number). For example, a file named Orchestra_1.bwf would create the audio on track A1.
To avoid display of a dialog box during import, you can specify the frame rate using the following syntax:
uFRAMERATE=nDF or
uFRAMERATE=nND
where nn is the frame rate (25, 29.97, or 30), DF is drop-frame, and ND is non-drop-frame.
