Looking for a specific effect to add to video

I'm trying to see if there is an effect which will slowly change 10 or 20 seconds of a video clip from colour to black and white, with the option to invert it the other way also

Does anyone know if there is such an effect available

thanks

I do not know an effect for that, but it can be done in PD16 without third party tools.
It is a little tricky, I cannot explain it, so I made a little video for you:



And excuse my bad english...

P.S. I thought about it again: Or you can play with the opacity of the second clip by keyframing the opacity from 0 (color clip is visible) to 100 (b/w clip is visible) and back.

The effects you need are there. Highlight the clip. Go to Fix/Enhance/Keyframe/Saturation. At the moment on the clip you want to begin in B&W move the saturation slider from 100 to 99. 10 to 20 seconds later in the clip move the saturation slider from 99 to 0. That is it. Do the reverse when you want to change the B&W back to color.

Yes. My first way was a kind of awkward : When I thought it back, using the opacity was the easier way.
