But what is your question? If you are asking- was it done with Motion- highly doubt it. If you are asking- could you copy the look in Motion- probably unless there’s a lot amount of 3D or motion tracking going on.
Well this app is pitched as Motion Graphics much more than compositing but having at least the time remapping tools FCP has would be a major plus. For compositing Shake, Combustion or After FX are far better suited.
Short answer no. Long answer- to a certain extent but as slow motion goes it’s probably the least effective. Better to use FCP or much better one of the true slow motion plugins like RE:timer.
What is chaging that you don’t want? I’d highly recommend first cutting the ball out into a circular shape and saving as a PSD. JPEGs don’t have alpha channels.
If you are planning to stay in the NTSC world with no plans for a filmout or 24p native DVD then that would work fine. Sorry for being huffy- I recently switched to decaf.
