Erasing wires should be easy with any half-decent effects/compositing program. 'Matrix shots' where you freeze time while moving the camera around are not.

However, if you want to 'freeze time' while the camera is stationary you can probably just shoot one shot that you freeze and a second shot with the moving actors and rotoscope them in... would be time-consuming and tedious though.

Add in the ball (or whatever object you decide to use) in post. Record as normal without the ball there, and then add it in later.

Like what Mark said, it'd probably be easiest to just "erase" the wires in post. If you want an effect similar to The Matrix, you'd have to record your video and put it in slow motion, adding the object in later.

thanks guys ill look into it.

A quick one you can try. Shoot a white ball dropping against a blue background. Then take a single photo using a digital camera of the white ball, against the blue background, on the ground - with the white ball in the middle of the frame. You can then use this static image, and composite - replacing the blue BG with your video. Voila, time is frozen? ball is suspended.

Shoot the scene in reverse. Hang the ball with the wires were you want it to 'freeze'. Then quickly swing the wires back the way the ball would come as it were thrown. Now reverse the footage so the ball appears to be thrown and then freeze in mid air. Cut to another shot of the static ball, then whip the wires again and off it goes down to the ground.
