AMA Linking with Ancillary Data
393
When you work with spanned clips, consider the following:
• If you remove a card that contains a spanned clip, for example Card 2 in the above example,
and you try to play Clip 1, it plays until it reaches the portion of the clip that resides on
Card 2. Media Offline appears until you reach the media on Card 3. Avid recommends that
you do not place another card in the removed card’s place unless you remove all the cards
that contain the spanned clip (Cards 1 and 3 in this example).
• You can mix cards that contain spanned and unspanned master clips. However, if you eject a
card which contains a chunk of a spanned clip and insert another card, the master clips in the
newly inserted card are not visible in the Media Tool but the media files are visible. To work
around this, remove all the cards which contain chunks of the spanned clip and choose
File > Unmount followed by File > Mount All (non-AMA method). All the master clips are
visible.
• P2 and XDCAM EX spanned media covers multiple drives, but the bin displays only one
drive letter. The drive letter in the bin might be any of the drives, but is usually the highest
lettered drive where the media exists.
• If necessary, copy all spanned clips to another drive to ensure a clip’s integrity before you
swap out the cards.
AMA Linking with Ancillary Data
You can AMA link to an XDCAM or an MXF (SMPTE 436M) clip with ancillary data, the
ancillary data appears in your bin. You can link to the ancillary data clip without an Avid
input/output hardware, however, in order to view the ancillary data in a monitor, an Avid Nitris
DX or Avid Mojo DX device is required.
For information about ancillary data and data tracks, see “Preserving HD Closed Captioning and
Ancillary Data” on page 1091 and “Data Track Method” on page 1092.
AMA Linking with Multichannel Audio
You can use the AMA Settings dialog box to define the audio track formats for the audio
channels in your linked media, up to a maximum of 16 audio channels for the clips in your bins.
This allows you to specify which source channels are treated as mono or multichannel audio
tracks in your project, rather than having to modify the clips in your bin after you link to the
AMA media.
The mappings affect all media clips created when you link to your source media. If you want to
use different mixes for different master clips or different projects, create a custom AMA Settings
template for each separate type of mix and then create your linked master clips.
