When you render effects using the Render at Position or Render In/Out command, the 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, the 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 seven effects on two tracks. If you use the Render In/Out command on this material, you render all seven effects. If you use the ExpertRender In/Out command on the material, the ExpertRender analysis recommends rendering only the three effects on the top track.

The ExpertRender option helps to solve the problem of unnecessary rendering by analyzing all the effects in selected material and by determining which effects need to be rendered to achieve successful playback. You can then choose to render the effects identified by ExpertRender or to modify the selections before submitting them for rendering.

ExpertRender attempts to generate a minimum set of effects to render for successful playback. If you render the effects recommended by ExpertRender, your material will usually play successfully in real time.

ExpertRender is particularly useful in the following circumstances:

In most circumstances, ExpertRender enables you to render material quickly, easily, and with a high degree of storage efficiency. However, experienced Avid users might achieve an even quicker render of a complex sequence than that offered by ExpertRender — for example, using Submaster editing.
