When rendering a single frame, either by pushing F12 or from the PropertiesRender menu, is there any way to speed up the process? I know about rendering animation through the Python console to speed up rendering time, but can this be applied to a single frame of animation?

    $\begingroup$ dont understand the question, I think you could re-phrase, are you asking how to make a screen-shot? $\endgroup$ – ideasman42 Jun 25 '13 at 13:19
  • $\begingroup$ Lindsey, the question is in danger of being closed, please clarify exactly what you mean and then 'flag' to reopen. Thanks. $\endgroup$ – iKlsR Jun 25 '13 at 15:46
  • $\begingroup$ Do you mean to do a quick openGL rendering of your animation like a playblast animation? $\endgroup$ – zeffii Jun 26 '13 at 9:26

there are several possibilities depending of your scene setup and renderer (blender internal [BI] or Cycles), but beware, most of them are lowering your overall quality. But we're faking all of the time in CG, so why not here too ;)

  • Reduce the number of subdivisions if you're using one or more subdivision surface modifier
  • BI: Reduce the number of mirroring surfaces (if any)
  • BI: Reduce the number of area lights and replace them with several spots
  • BI: Turn down Anti-Aliasing
  • Cycles: Reduce the number of samples
  • Cycles: Disable the usage of caustics
  • Cycles: Split your scene in different passes and render with a different sample count (less samples for simple passes, more samples for heavy passes)
  • Cycles: Disable motion blurring
  • Cycles Use the direct light Integrator preset (changes your scene appearance too - be warned)

  • Decrease your image resolution...

The possibilities are really countless and depend heavily on your scene - so it's really hard to give a specific answer in your case.

You can save a file with F3 when you're above the rendered image.
