Sigma is quite right, continuous mouse control is required for my solution.
But then if you want to control something with a mouse that is sort of a given no?
Try out the scratch controller anyway with all the speed knocked off your clip. It is more effective with some clips than others.
You can try routing the bpm to the 'scratch controller' and/or the layer 'speed' settings which is fun and frees a hand for beer.
This would allow you to have a movies position and speed controlled automatically to the beat.
Open the 'BPM (global)' module and then route it using either 'master' or 'layer' BPM Router modules or my favourite
the 'L-BPM ROUTERV2 Ergo Mouse' -
you can pick almost any controllers from the gui are to be controlled by the master BPM and set their in/out points using these modules.
Great fun and very effective.
