What is a good frame rate?
A frame rate above 15 generally gives good results. Lower rates may give acceptable results if important movements are slow. If the frame rate is too low, your video will be jerky. In that case, you may be able to improve your results by adjusting your graphics settings Edit>Preferences>graphics>check customize an turn down features you don’t need in your video. Also cut down unnecessary activity in your scene — particles, bling, moving objects not part of the story. Leave the camera steady and let the avatars, objects, and sound tell the story. Put the story on a set and enclose it so the camera does not see anything not in your story. Also close all unnecessary programs running in the background. Consider adding more memory to your computer. You need at least 1 G and 2 is better.
