A VEG file functions as a non-destructive edit snapshot in VEGAS Pro, storing only references to imported clips rather than embedding any footage, while keeping metadata and every editing action—from trim points to transitions and color tweaks—so the file stays small and depends on the original media, which VEGAS Pro reloads when opened, producing missing-file alerts if clips were moved, and no real video is generated until rendering, since playback always pulls from the source files.

Rendering is the moment edits become an actual file, as VEGAS Pro reads the media, applies all stored edits, and writes formats like MP4 or MOV, while deleting the VEG file leaves the footage intact but removes all project instructions, highlighting that the VEG file is an editable blueprint instead of a finished video, with rendering being entirely separate since the VEG file cannot create frames and only drives temporary previews until the final export is made.

Rendering is the moment when edits stop being temporary and become permanent output, with VEGAS Pro processing each frame in sequence, applying every edit, effect, transition, color correction, and audio adjustment before encoding into MP4, MOV, or AVI, producing a standalone file that works without the project structure, leaving the VEG file editable but not suitable as a deliverable, and if removed, taking all edit decisions with it, while a lost render can be recreated anytime as long as the VEG and source media exist, making the VEG file the master document and rendering the irreversible creation of the finished video.

Opening a VEG file makes VEGAS Pro read the internal project snapshot, which outlines how the timeline was last configured, without copying any video or audio, identifying tracks, clip placement, effects, transitions, and settings, then searching the system for every referenced source file and rebuilding the project when everything is present, or asking you to find missing items since the VEG file includes no actual media.

When media links successfully, VEGAS Pro builds the preview on the fly to combine the source footage with transitions, effects, color work, and audio processing, which stresses system resources and doesn’t generate a finished video, allowing unlimited edits and serving only to reopen the project environment so you can continue working until you choose to render the final output.
