A VEG file acts as a lightweight non-destructive project record 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 If you have any questions regarding in which and how to use VEG file windows, you can speak to us at the site. .
