ExpertRender
ExpertRender determines which effects need to be rendered to achieve successful playback of a
sequence.
You can use the ExpertRender feature in the same way that you use the standard Render
commands. You can use the ExpertRender at Position command or you can mark IN and OUT
points and then use the ExpertRender In/Out command. For more information, see
“Using the
ExpertRender Command” on page 159
.
If your Avid editing application has difficulty previewing effects in real time and displays
playback information indicators in the timecode track of the Timeline, the steps you take when
you use the ExpertRender In/Out command are somewhat different from the steps you take when
you use one of the ExpertRender commands in other circumstances. For more information, see
“Using the ExpertRender Command After a Real-Time Playback Attempt” on page 161.
For more information on rendering, start with
“Basics of Effects Rendering” on page 51.
Understanding ExpertRender
When you render effects by using the Render at Position or Render In/Out command, your Avid
editing application renders all effects in the selected material — all effects on the enabled tracks
at the position or all effects on the enabled tracks between the marked IN and OUT points. In
most cases, your Avid editing application renders some effects that do not require rendering for
successful playback, increasing the time to render and creating more precomputes than
necessary.
For example, the following sequence includes four effects on four different tracks. You could
render all four effects, however if you use the ExpertRender In/Out command on the material,
the ExpertRender analysis recommends rendering only one of the effects.
