Extracting jpg from animated gifs

[Maz]

Hi There

I have a problem

I have an animted gif, where i want to extract a jpg from
so i access the gif , and handle each frame as a BufferedImage
so far so good, that works

but if i try to create a jpg from a certain buffered Image
i get a jpg that has completly corrupted colors
It looks very reddish, like there would have been a filter applies to it!

Can anyone help me and tell me where the problem is?

best wishes
