Must preview files be saved?
1. I ran out of on-board disc space, and not keen on using external drives for video work. My Ppro – Preview Files (.PRV) are 24GB+ . After I use DynLink to burn a DVD, is there any reason for keeping the preview files (.PRV)? I assume that if I always keep the project file (.prproj) for that DVD, I can always re-render and re-produce the DVD later if I wanted. So I see no reason to kept the preview files…… right?
2. Curiosity question: why are the preview files so large? I thought Ppro used pointers instead of the actual file footage to built the timeline and the eventual render. Obviously the rendering compiles the actual source footage vs pointers, and maintains the compilation?
Thanks,

1- Correct, no reason to keep them.
2- In previews, you render full video files, the format depends on the timeline/sequence. In DV, it’s DV, in desktop mode, it’s usually uncompressed. In some sequences, you can choose from different formats.
