Rotoscope is the only way with this program, else you could take the time and learn how to match move unsure

Is the one object a specific colour? If so, you should be able to key off it and avoid having to do too much roto work.

Just copy the layer, then apply a chromakey filter to the top one, picking the colour of the object. Make sure you invert the key, so that only that colour is left.

You can then set the lower layer to black and white, at which point the coloured layer will sit on top.

To add to Tarn's point, even if the object is two or three different shades of red, you could still accomplish this without roto work by making multiple keys. The important thing is really just that the color(s) of the object are distinct from those of the background.

I made this a few years ago and happened to have posted it in response to someone else's question just a few days ago.

Hopefully it helps.
