Automatic Render Controls

ch-rendering_auto-render-controls

 

These controls are automatic in that they are toggled on or off, and affect the render processing from then on.

Render BG

ch-projectmanagement_render-button-render-bg

 

Default : On

 

With The Render BG button enabled, some resources are devoted to rendering the active composition in the background while you work. This background rendering will only occur if the application is otherwise idle and will pause when a more important workload surfaces (e.g. if you play the timeline, or need interactive response during grading adjustments).

 

By default, all new projects have the Render BG button enabled.

 

dv_note

Render BG can greatly reduce rendering requirements with little impact on your interactive work. It is generally a good idea to leave it enabled.

Render FG

ch-projectmanagement_render-button-render-fg

 

Default : On

 

This will cause unrendered portions of the timeline to be rendered for display when playing timeline. If this button is disabled, playback of unrendered timeline areas will display grey "not generated" frames :

 

ch-rendering_frame-rendered

ch-comp_notgenerated

ch-projectmanagement_render-button-render-fg

ch-rendering_render-fg-button-off

Cache

ch-projectmanagement_render-button-render-cache

 

Default : Off

 

The Cache button is relevant to composition playback only. During timeline playback, any unrendered frames are rendered on-the-fly dynamically for display (if Render FG is enabled) but are not normally saved to disk. Enabling the Cache button causes any unrendered frames encountered during playback to be saved to disk.

 

dv_note

This rendering is identical to that done with Render BG enabled or when doing a Render Output operation, except it occurs only during timeline playback (of unrendered frames).

 

dv_alert

Enabling the Cache button may affect timeline playback due to the extra work required to save out rendered frames to disk.

Transition

ch-projectmanagement_render-button-render-transition

 

Default : On

 

The Transition button enables the rendering of transition effects (e.g. dissolves).
