Capturing Ancillary Data with a Data Track
While you capture video and audio clips, if your Avid editing system has an Avid Nitris DX or
an Avid Mojo DX attached, you can also capture clips with ancillary data.
You perform the same steps included in “Preparing for Capture” on page 159 and “Capturing
Media” on page 223 to capture video and audio media. Make sure you select the Data track (D)
Channel Selection in the Capture tool. You also need to select the appropriate ancillary data
options in the Capture tab of the Media Creation Settings window.
To capture clips with ancillary data:
1. Prepare your deck for capture. Follow the steps in “Preparing for Capture” on page 159 and
“Setting Up the Capture Tool” on page 185. This includes selecting the D Channel Selection
button in the Capture Tool.
2. Select SMPTE 436M and the type of ancillary data you want to capture in the Capture tab of
the Media Creation Settings window. Follow the steps in “Controlling Ancillary Data
through a Settings Window - Data Track Method” on page 1100.
3. Decide on your method of capture, see “Capturing Media” on page 223 for more
information.
Depending on the options you select, ancillary data clips along with the video and audio
clips you selected to capture, appear in the bin.
Performing a Data Mixdown
With the Data Track method, a data mixdown lets you combine several clips into one new master
clip. You can use data mixdown after you finish building your sequence and want to make it into
one piece.
Data mixdown is useful when you want to:
• Combine multiple ancillary data clips into one master clip.
• Finalize a complex sequence before you consolidate, export, or transfer.
With data mixdown, your end result is a new master clip made up of all the data clips on the data
track. That track becomes one clip.
To perform a data mixdown:
1. Select the Record Track Monitor button in the Track Selector panel for the data track.
2. Mark an In point and an Out point around the area to mix down, or clear the In and Out
points to mixdown the entire sequence.
3. Select Special > Data Mixdown.
