Nero 7 Slide Shows

Postby sdculp on Tue Feb 20, 2007 6:19 pm

I make a lot of DVD slide shows with Nero 7. A typical nvc file of 900 slides occupies 299 KB of space. The jpg's used to create the nvc file occupy 864 MB. This amounts to a picture compression of 2890, or about 299 bits per picture. The resulting slide show looks very nice. This sounds impossible!! How do they do that???

I don't use the app, but more than likely the NVC file just points to the JPGs which are then used in the authoring process... it's not recompressing the images and storing them in the NVC file.

Thanks for the response. I should have thought of that. I checked the file size on the DVD and it was 316 MB. Not as large as the original jpg files but apparently good enough.

It probably drops the JPGs down to TV resolution (720x480 for NTSC) and so does do SOME recompression.. but nothing miraculous. :)
