Grass Valley Aurora Edit v.7.0 - Manual (Page 112)

Understanding Aurora Edit's Agile Timeline
Aurora Edit allows you to mix and match video formats in real-time within the same
Timeline.
Administrators can enable mixed-format (Agile) Timelines from Tools | Options |
Timeline by checking the Allow Mixed Format Timeline checkbox. When this setting is
enabled, users are given the option to enable mixed formats when creating a Timeline.
While Aurora Edit allows this real-time mixing and matching of formats within a
Timeline, all clips that differ from the Timeline's default video format must be
transcoded when sent to a media or playout server. With this in mind, editors may
choose to enable or disable mixed-formats on a per-Timeline basis, depending upon
their needs. This feature can be configured from the New Sequence or Sequence
Properties window.
When disabled, clips that don't match a Timeline's format are transcoded when they
are added to the Timeline. When enabled, clips that differ from the Timeline format
appear with a blue bar above the clip to indicate that transcoding will take place when
the sequence is sent.
Clips on a Timeline, as well as other effects, are transcoded by selecting Render All .
You can also manually transcode a clip by right-clicking on it and choosing Render
Selected .
NOTE: Aurora Edit LD cannot render. The conform process will handle this.
If not transcoded prior to sending, Aurora Edit transcodes them automatically when
they are sent via either the local editing machine or a Conform Server.
Note that NTSC and PAL formats cannot be mixed on the Timeline.
Mark Points
About Mark Points
You can set the Mark Points using the Mark In and Mark Out buttons in either the
Timeline Tool or the Source Tool.
The steps to create a mark point are the same regardless of which tool you are using,
but you will be setting different mark points in the two tools. In the Timeline Tool,
you are setting mark points for your sequence; in the Source Tool, you are setting
mark points for the input source.
When you make the first edit in a sequence, you can mark In and Out points (optional).
If you don’t set a Mark In point, recording starts at the current position of the cursor.
If you don’t set a Mark Out, Aurora Edit creates an Out when you stop recording and
