With "overlay[...],fade[...],fade[...]", you're appying the fading to the whole video and not just the overlay. It's a filter chain, you see, and the fade filters are chained behind the overlay. You will want to do something like adding "-loop 1" before the overlay image, and then using a filter like this: -filter_complex "[1:v]fade=t=in:st=5:d=1,fade=t=out:st=10:d=1[over];[0:v][over]overlay=0:0" (First creates an in+out-faded version of the overlay image as "[over]", then overlays.
