Write out animations to separate files? Is there any way I can, after rendering an animation/physics simulation, write out said animation to an external file? Needs to be a file format compatible with Linux (I'm new to Linux so unfortunately I don't know what sort of file would work for this). I also need to be able to, ideally, do this within the script controlling the animation/simulation.  

Thanks so much!
Yes, Go to rendering panel and change the format [ GREEN ] to AVI JPEG or AVI RAW For more high quality without using a sequence of images. Select image files [ GREEN ] Such as PNG or JPEG for image sequences which you can put together manually but are usually more high quality. Click the folder [ YELLOW ] To select where to save the file.
