# Load and Save

The Save button allows the user to save one frame to a new directory give the name of the Movie Title entry field entry and with the file extension specified in the File Extension entry field. The Frame entry field tells the user which frame number is going to be saved or loaded. This field can be manually set, however; the user must set it to the frame number before the frame of interest.

The Load button first prompts the user on whether the movie should be loaded in discrete mode and then opens the directory specified in the Movie title entry feild. As more frames are loaded the frame number increases to correspond with the current frame.

The Ray Trace Frames check box plays the movie back with each frame ray traced. This severly slows the movie progress, but is essential for creating an MPEG movie.

The Create PNGs button creats a series of numbered PNG (picture) files for which correspond a a frame of the movie. These PNGs are saved to the PyMol root folder and can be imported into a movie maker to make stand alone movies. If Ray Trace Frames is check, each frame will be ray trace, which vastly increases the quality of the movie.

The Frame Cache Off check box should be used for movies over 100 Frames long and keeps the RAM from being filled.

The Clear Ram button clears loaded froms from the computers RAM.
