Using mixed aspect ratios in a playlist
The iDDR can play clips with different aspect ratios in a single playlist. How the
media is displayed is determined by the play channel widescreen setting and clip
aspect ratio. The play channel determines the clip aspect ratio by examining the clip
aspect ratio attribute set when the clip was recorded. The following table describes
how the iDDR displays mixed aspect ratios. (See also
“Video scaling considerations”
on page 37 ) .
Using mixed video resolutions in a single playlist
Playlists can contain events with different video resolutions. When the list is played,
the media is up-converted or down-converted as needed to match the play channel
video output type selected. See also
“Video scaling considerations” on page 37 .
NOTE: The transition between events with different resolutions takes approximately
1 second. During this time, play channel output is switched to black.
Inserting a clip that is still recording
Clips that are currently recording behave as other clips do in a list except for the
following restriction:
• The event-out timecode is set to the last recorded frame at the time the clip is
inserted in List view, or created in Event view. You can move the event-out
timecode as needed while the clip is still recording or after record is stopped.
Inserting a playlist in a playlist (workarounds)
While iDDR does not support a true “nested” playlist, you can retain some of the
functionality of inserting a playlist in a playlist in the following ways. These are
available in workstation operating mode only.
