If you are really in a hurry, i am afraid that you will have to find an 
external solution, because anyway exporting figures within Scilab is 
quite slow, even in bitmap encodings. This has been reported here 
<http://bugzilla.scilab.org/13904> and is still the case.

Otherwise, you can use animaGIF(), that can avoid storing all 
intermediate images, but that does not avoid creating them. So, it saves 
disk space, but not time as you request. It does not really aim to make 
video with a "normal" frame rate, although it can mimik it.
