1. A computer-implemented process for processing video signals in a video processing system, comprising the steps of:
- (a) exporting, by a file-processing subsystem, functionality to an application to select optional preloading of a file by the file-processing subsystem;
(b) optionally selecting, by the application, preloading of the file; and
(c) preloading the file, by the file-processing subsystem, in accordance with the optional selection by the application.

Abstract
A file-processing subsystem exports functionality to an application to select optional preloading of a file by the file-processing subsystem. The application optionally selects preloading of the file and the file-processing subsystem preloads the file in accordance with the optional selection by the application. In one embodiment, video frames may be preloaded from a video file, where preloading may include decompressing the video frames. In addition, the preloaded video frames may be retained in memory for repeated display.
