Add the switch: -truecolors

Can some help me?

I think so. In your command you want to convert a GIF image to a JPG image. GIF images use a colour palette with a maximum of 256 different colours, whereas JPG uses truecolour (16 Mio.). nconvert will not do the required transformation automatically, you have to add -truecolor to do this conversion:

Code: Select all

nconvert" -out jpeg -truecolors -o output.jpg input.gif

Edit: Oops, marsh was 3 minutes faster with his answer.
