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